We came home from BJJ still arguing about the last round. I dropped my bag by the door and pointed at him.
"You're too strong now. That pass was bullshit and you know it!"
Luca pulled a face I've seen before. His mouth was a little twisted, eyelids half down. I know he disagreed, but he didn't say anything and that irritated me. He turned toward the kitchen like the conversation was already over.
I followed him. "Don't do that. Don't pull the face and walk off. Admit it!"
He kept walking.
"It's so not fair, you spend half the late night training sessions at the pub instead, but I'm the one who falls behind?"
I caught the back of his rash shirt and yanked him around. We were the same height, or close enough that my chest sat between us, full and high even in the training gear.
"I'm serious, you're too strong. I used to be able to get out of that."
Luca looked at me for a second, then the corner of his mouth lifted.
"I've been stronger than you since I was thirteen, Sofia. You just didn't notice because you were a bit taller."
I opened my mouth but he kept going. "And it's not only strength. It's your chest. Every time you try to turn or get your elbows in, they're in the way."
I stared at him. He wasn't wrong -- the pass had left me fighting my own body as much as I was fighting his. My breasts, usually useful when I wanted attention, had turned into a liability in anything physical and slightly competitive. I hated that he'd noticed.
"That's a cheap shot!"
"It's an accurate shot." He reached past me for a glass. "You still have great underhooks, you're just carrying extra up top."
I shoved his shoulder. He barely moved -- that was new too.
Later, after we had both showered, the house was quiet. Our parents weren't back until midnight. I found Luca already in my room, stacking the big pillows against the headboard the way we always did when we watched shows late at night. I changed into a loose crop top and soft shorts and climbed into the bed next to him where we settled in, backs against the pillows, with the laptop on a cushion between our knees.
I put my feet over his thighs the way I always did. He rested a hand on my ankle without thinking about it. A familiar easy silence settled over us -- a comfort in each other's physical presence. Every so often I caught him glance sideways when I shifted and the top pulled tighter. I rolled my eyes once and he looked away, but there was no real embarrassment. We'd seen each other in less.
Still, the comments about my chest sat in the back of my mind. Not because it hurt my feelings, but because it was the first time he had voiced a physical difference between us that changes how we interact.
After the episode I stretched, arms over head, and felt my top ride up even higher. Luca's eyes flicked down and then away again, quick. I noticed, but I left it.
"Want another one?" I asked.
"Yeah."
I started the next episode. His hand was on my ankle thumb stroking me once more, thumb tracing an absent circle. It wasn't really deliberate, I don't think, it was just us. The same way it had been for years -- except now he was stronger and the quiet house felt a little more cozy to me -- and I felt no reason to move myself or his hand.
Half way through the episode he stretched, and when he settled again his forearm rested against my side, higher than before. The warm edge pressed along the underside of my breast through the thin fabric. He didn't seem to notice, or he noticed and decided it didn't matter. I waited to find out which one it was.
A whole minute passed and his arm had stayed exactly where it was. It was warm and the weight of it lifted the curve of my breast slightly with every breath I took. I could feel the shape of myself against him -- full and heavy. My nipple had started to get firmer from nothing more than the quiet contact.
I turned my head just enough to look at him. He was watching the screen, but he was clenching his jaw.
"Your arm." I said, softly.
"Mmh."
"It's under my tit, Luca"
Luca glanced down, saw the awkward placement, then still didn't move. "Yeah."
The air immediately felt thicker and I could have moved away, but I didn't. Instead, I stayed exactly where I was and let the next breath press me more firmly into his forearms. The soft weight of my breast settled heavy against him. He exhaled through his nose, slowly.
"You can leave it," I said. "It's... fine."
Luca's eyes met mine for a second and he gave the smallest nod before turning back to the screen. But his arm didn't lift. If anything, the pressure increased by a fraction -- it was deliberate now.
We watched the rest of the episode with my feet in his lap, his forearm under the curve of my chest, and the house completely quiet around us. Every time I breathed I felt myself move against him. No commentary, just steady, warm contact and the knowledge that I had given him permission.
When the credits of the episode rolled I didn't sit up immediately and neither did Luca. The weight of his arm stayed, solid but careful, and for the first time I let myself notice how good it felt to be there.
I reached for the laptop to start another episode. He didn't object, and his thumb began tracing the fine circles on my ankle again. Under my crop top my nipple had drawn tight against the fabric, impossible to ignore.
Another twenty minutes passed before we spoke, long after the show had since become background noise. Luca's arm was still propped against my breast and at some point his hand had opened so that his fingers rested against a soft side. He wasn't gripping it, just being present. His palm felt hot through the thin fabric of the top and I stayed perfectly still, afraid that any movement would alert him and make him recoil away.
But when the episode ended, he still hadn't moved his arm. I didn't ask him to and the silence stretched to fill the void. It was comfortable but charged at the same time.
"You're quiet."
"Thinking," he replied.
"About what?"
He took a long second to answer. "Nothing important."
I tilted just enough that the full weight of my breast settled into his hand. His fingers flexed once, almost involuntarily, and then relaxed again. My nipple was pinched tight and protruding so obviously that I was sure he could feel it.
I kept my voice light and inquisitive. "You can actually hold it, you know. If you want."
The words hung in the charged air. Luca's breathing changed before he slowly and carefully turned his hand and cupped me properly over the fabric. His fingers spread out under the heavy curve, and his thumb was just below my nipple. The fit of his hand against me felt deliberate and new and caused me to let out a small breath. I leaned into it a little more. This was nicer than I expected.
He didn't squeeze or grab, just held the weight of me. I sat enjoying the warmth while the next episode started on its own. Neither of us reached for the laptop. His thumb moved once, a slow stroke along the underside, and I felt a wave of goosebumps ripple over my back and stomach.
We stayed exactly like that until the episode finished without further conversation. No jokes, no banter, just his hand under my breast and my feet over his thighs. The quiet understanding that something had been allowed tonight that we had never done before.
When I finally stood up his hand slipped away. The place where it was now felt cold. I straightened my top, though it didn't help hide my shape or the fact that my nipples were visibly protruding from the fabric in frustration.
Luca cleared this throat and stood up. "I'm getting water. Want any?"
"Yeah."
While he was in the kitchen I sat against the pillows and stared at the paused screen. My pulse raced and I swear I could still feel a tingle in the shape of his hand on my skin.
Three nights later our parents were out again and I heard Luca moving around the living room. I stayed in my doorway for a minute, deciding, and then went to find him.
"Bed?" I asked.
He followed me without a word. We stacked the big pillows against the headboard, opened the laptop, and settled in the same as before. But this time I didn't wait as long. Once the show had started, I reached down, took the hem of my top -- another crop top -- and pulled it up above both breasts in one motion. The air was cool on my skin, and I let the fabric bunch under my arms as I leaned back over the pillows.
Luca went still.
"I said you could," I reminded him, quietly.
He nodded once, then his hands were on me. Both hands this time -- cupping the full weight skin-on-skin without hesitation. He lifted them, felt the shape, let his thumbs brush my hazelnut nipples until they reacted. I watched his face while he did it. The concentration made something pull tight low in my tummy long before the sensation on my nipples took centre stage.
Luca spent a long time just holding and stroking. I noticed his eyes kept dropping from the screen to my chest and staying there -- after a while the show may as well have been silent. He was simply watching what his hands were doing, and I started to admire the sight too. Watching the way my breasts moved under his touch, the way my nipples reacted and wrinkled tight to his friction, the way the soft weight filled his palms. He looked almost mesmerised by it, and he by him. Distracted from everything else.
I stayed quiet and let him be him. His thumbs kept circling and his breathing had gone shallow. After a long stretch of that attention I watched him lean in a bit, hesitate, and then allow himself a single slow lick across just one nipple. The wet heat of it made my breath catch. He pulled back immediately as if he had done something wrong and returned to only using his hands, but I didn't react.
We stayed like that through the rest of the episode. He didn't lick again, he simply kept playing with me while his eyes moved between my face and bare chest. When the episode ended he carefully withdrew his hands. I pulled my top down and savoured the texture of the fabric on my still sensitive nipples.
Luca shifted on the bed and I could see how affected he was from the evening by the front of his shorts. I looked at it openly this time, long enough that he noticed, then looked back at his face.
"I'm going to bed," I said, even though we were already in it.
He understood. "Okay."
The next time our parents were out came almost a week later. I heard the front door close and the car pull away. I waited a few minutes and then walked down the hall and leaned against Luca's doorway. He was on his bed on his phone, but he looked up.
"They're gone until late," I said. "Want to watch something?"
"Yeah."
We ended up in my room again, stacking the big pillows. I had already changed into a loose top and shorts. He settled in beside me and I opened the laptop -- an old series we both knew by heart was already queued up, but I didn't press play yet.
I kept my eyes on the screen.
"Do you want to play with my tits tonight?"
The question came out plain, almost casual, but inside my heart was racing. I heard Luca's breath stop for a second.
"Yes," he replied.
I nodded once, then hit play. A few minutes into the episode I reached down and pulled the oversized shirt up to my collarbone. My nipples reacted to the cool air immediately, twisting into little caramel kisses. I arched back over the pillows and waited.
Luca's hands were on me before the first commercial break. Skin on skin, both palms full, thumbs already brushing the peaks. I let my eyes close for a while and simply felt the slow exploration, the careful attention, the heat of his palms and breath. His hands stayed on me while the laptop played on, ignored.
I opened my eyes to watch his face a while longer, then leaning in and kissed him.
It wasn't a careful, testing kiss. I committed. I pressed my lips into his with intent, one hand sliding up into his hair. The kiss was deep and open and unmistakeably deliberate. I felt his surprise, but then he responded by kissing me back harder, his hand gripping me tighter, fingertips sinking into my bountiful softness. When I finally drew back, our breathing had changed.
I stayed close enough that our foreheads were almost touching. "Was that okay?" I asked quietly.
He nodded, eyes dark and turned away. "Yeah. I... I liked it."
Only then did he lean down and take one nipple into his mouth. I inhaled sharply before he licked in slow circles, then sucked, gentle at first and then with more purpose. When we switched to the other nipple I slid my fingers into his hair and held him there, a silent scream frozen on my face.
He took his time. Long, deliberate pulls of his mouth, his tongue dragging firmly across the raised point. Occasionally he would allow the brush of a soft, smooth surface of a tooth that made my hips pivot against the mattress. Every so often he would pull back just far enough to look at what he had done -- nipples glistening and flushed with deep red, breasts blushing -- before leaning in again.
I felt myself getting wetter with every minute, I couldn't control it. The sensation playing over my chest was sending shockwaves directly to my clit, and the time between shocks was quickening rapidly. The soft shorts were pressed firmly between my thighs and I knew they were soaked through. Luca's mouth moved from left to right and back again, unhurried and arrogant, like he had decided he could take as long as he wanted. As he sucked a nipple deep onto the back of his tongue he let out a low groan and undulated his tongue, causing me to let out an involuntary squeak. He reacted by tightening his hand on the other breast.
How we managed to continue that through a whole episode I do not know. By the end my chest was slick from his attention and my breathing was erratic. Luca finally lifted his head and his lips were bright red. He kept one hand cupped over me, thumb still stroking slowly, and met my eyes with his.
"You good?" he asked, voice rough.
"Yeah." I sounded just as rough. "Really good."
He gave me one last slow squeeze and sat back. I left the top where it was for another minute before I finally pulled it down. It clung to the wetness he had left behind.
Luca shifted. The outline in his shorts was impossible to miss. I looked at it the same way I had last time -- openly, without pretending I didn't notice -- then back at his face.
"Same deal next time?" I asked.
He could only manage a nod, still breathing carefully.
I waited until he had left the room. Then I pushed my shorts down, lay back against the same pillows, then slid my hand between my legs while the feeling of his hands and tongue were still vivid on my skin. I came quickly and quietly, already planning how much further I would let him go next time.
The night it went further started the same way as the others.
Our parents had left for a long dinner. I heard the car pull away and felt the familiar decision grow as an ache in my chest. I changed, but this time I left the top and shorts in the drawer. When Luca appeared in my doorway, I was already under the covers, the sheet pulled up to my waist, everything above it bare.
He paused; I saw a little panic at the change of routine.
"Come on," I encouraged with a smile. "Same as usual."
He closed the door and stacked the pillows. I lifted the edge of the sheet so he could get in beside me. The laptop was already open and I started an episode neither of us would remember.
As soon as he hit the bed and settled I grabbed his hands and put them on my breasts. He made a low rumble and leaned in, his mouth finding a nipple while both hands worked. I kept the sheet over my hips and thighs and let him have everything else.
He was more confident now with longer pulls of his mouth, chancing stronger suction. At some point he shifted closer and I felt the hard length of him press against my thigh through his shorts.
I discretely slid my left hand under the sheet while he was busy and found myself already excited. I moved my fingertips in slow circles, matching the rhythm of his tongue. He didn't notice.
He spent a long time on each breast but then he changed what he was doing. Both hands came up along the outer curves, fingers spreading wide, and he gently pressed my breasts together until my nipples almost touched. He leaned down and took them both into his mouth at once.
The sensation was immediate and overwhelming. His tongue flicked and swirled across both sensitive buds at the same time. Hot electricity flooded straight down my body, branching out like a tree as the sensation made its way between my legs. My fingers moved faster under the sheet, sliding effortlessly through the wetness, circling with more pressure.
I had to work to stay quiet. My breathing wanted to break. My hips wanted to buck. I clenched my teeth while the pleasure built in tight, rising waves. I kept my movements small and careful and the sheet barely betrayed me. Luca licked a slow path from one peak to the other, then sucked both deep in his mouth, harder. The additional pressure pushed me over.
The orgasm hit hard. I clenched around my own fingers and had to actively tense every muscle to keep from making a sound or moving the sheet. Pulse after pulse ran through me while he continued, completely unaware. The orgasm was sharp and private, but satisfying and entirely needed. I bit the inside of my cheek to stay silent as I rode out the waves that kept coming with each swirl of Luca's tongue or press of his imprint into my exposed bottom half.
Luca kept going for a while longer, mouth and hands unhurried, before he finally lifted his head. His lips were wet and flushed again. He looked satisfied and even a little dazed, but he didn't know anything had changed.
"You good?" he asked.
"Mhm." My voice was steadier than I expected. "Really, really good."
He gave me one last caress and then leaned back. I pulled the sheet higher, suddenly aware of how naked I still was underneath it. The evidence of what I had done was on my fingers and the inside of my thighs. An uneasy heat began to replace the normal relaxation.
We finished the episode in near silence and when it ended I told him I was tired. He left without pushing and as soon as the door closed I rolled onto my side and stared at the wall. I had crossed a line he didn't even know existed.
The next morning I kept my distance a bit. When he suggested watching something the following night I said I was busy. The night after that, I was too tired. I let the routine drop -- no more invitations, no more lifting my top. When we ended up too close on the couch or in the kitchen I made sure the space between us was maintained again.
He noticed, of course, but he never asked and I didn't explain. Part of me was still replaying the way his mouth felt while I came under the sheets. But the other part of me kept insisting it had been too much and far too easy to want again.
And so I withdrew to almost nothing. Maybe the occasional, careful contact under my shirt after a genuinely bad day. Never in bed. Never fully bare. Never for too long. The full routine had stopped and I told myself it was safer that way.
I still thought about the size of him when he got hard against my hip or thigh. I still felt that private swell of pride, but I didn't act on it. Not for months.
Instead, life filled the space. I went on a few dates that turned into three very short relationships. Each one ended the same way -- polite disappointment in bed, the quiet sense that something is missing. A lingering frustration. None of them finished me, so I finished it with them. None of them even came close to the attention and dedication I had become used to.
I thought about my brother more than I wanted to admit. The way his hands treated me with reverence. The night I came in secret under the sheets. Even the single, careful lick. What I most thought about was the thick, obvious shape of him when he got hard -- it was why I had to keep my distance, to keep safe from myself.
Then one Thursday our parents announced they would be out late on Saturday -- dinner and a long drive back. The familiar ache set in my chest before I could stop it, and I knew what decision I had to make to get it to go away.
Saturday night I was already naked under the covers when I heard him in the hallway. I had left my door half open on purpose. When I saw his shadow approach my door, I spoke first.
"Come in."
Luca stepped inside and closed the door. I lifted the sheet in invitation. He hesitated a second but then stacked the pillows and jumped in beside me enthusiastically. The laptop stayed closed on the desk and neither of us reached for it.
I was already touching myself when he turned to me. Slow circles over my nipples, keeping them erect, transfixed his attention and I drank in his expression.
"You can be naked too," I said. "If you want."
Luca stripped without breaking eye contact and I felt the heat emanate off him as soon as he slid under my covers. We were making direct, naked contact from shoulder to thigh and I felt the hard length of his cock resting against my hip heavily. I reached down and wrapped my fingers around it, just once, feeling the girth and the heat.
"I need to tell you something."
He waited.
"That night I was completely naked under the sheet... I came. While you were licking me. You didn't notice."
Luca's breath escaped him slowly. "I used to go back to my room and finish myself every time after I left you."
I stroked him once more as we absorbed our shared truths and found him even harder than before.
"Do you want to make me cum this time?" I whispered closely, with a sly grin.
He nodded, eyes dark as they had been months ago.
I pushed the sheet down, swung my left leg over him, and straddled his lean thighs. I wasted no time, wrapping my hand around the base of his cock as best I could, angled him up, and sank down just far enough to take the head and a little more. The entry made my breath catch. He was thick enough that even at this shallow depth it felt like a lot.
"Pull out," I instructed, voice already unsteady. "Cum on me anywhere you like. Just not inside. Anywhere else is fine."
I rose and dropped again, only a few inches of the tip slipping in and out. Once. Twice. On the third slow sink his whole body locked under me. My hand could feel his balls tighten close to his shaft, which jumped hard in my grip, once, then again. I could feel it in my hand before I registered it inside -- hot, powerful surges travelled straight through my palm. Even though he was only partially inside me, the angle was apparently perfect. A powerful, heavy pulse shot straight up into me. I felt the wet impact deep inside and the long ropes kept coming while I stayed frozen on him, shocked at the force of it and how clearly I could feel it. Not like this.
I stared down at him, breathing hard. His hands were on my thighs, grip tight, face stunned.
"It's... It's okay," I said quickly, softening when I saw his expression. "Really. We can try again tonight while they're still out."
I lifted off him carefully, expecting a slow leak, but none of him escaped me. Neither of us spoke for a moment. The line we had just crossed was still settling around us and I already knew we were going to cross it again before the night was over.
We stayed in my bed for a while after. Luca's hand rested on my hip, idly tracing small circles. Neither of us reached for clothes and we had no need to -- our parents wouldn't be back for hours yet. The house remained quiet and ours.
I rolled towards him and kissed him properly. He answered it immediately with a slow, deep, and passionate kiss. When we broke apart I took his hand and guided it between my legs so he could feel how excited I still was. I jumped as his fingers firmly slid over my oversensitive clit.
Luca made a satisfied low growl and slid down the bed in an instant. Three careful licks made me squeal loudly, echoing down the hall. My hips lifted into him involuntarily before I dropped back against the pillow and opened my legs for him. He settled between them, braced on his forearms, and pushed inside in one smooth motion, fitting in about half way.
The intense feeling of being filled made me close my eyes, stretching me more than I had ever been. Luca drew back and thrust in again as deep as he could. I kept my eyes shut and let the sensation roll through me, a quiet sound of pleasure parading from my perpetually open mouth. A third stroke bumped my cervix and sent waves of aching pleasure throughout my whole abdomen; I was lost in how good it felt. And then his body tensed hard.
Luca pulled out with a strained sound and came hard. Long strands shot far up my stomach, across my breasts, and reached as high as my collarbone. His heavy member swayed between my legs and shot three or four huge loads before his O-face was replaced with the look of surprise.
I opened my eyes, snapped out of my trance, and I stared down at the mess streaked all the way up my body, mouth falling open in pure amazement. Then I tipped my head back against the pillows to let out a short, disbelieving laugh.
The look on his face softened me right away and I reached for him smiling.
"It's okay," I reassured him, trying to keep my voice warm and accepting. "Really, it is."
I guided his mouth back between my legs before the frustration could take hold. He took his time and traced his tongue up and down, side to side, the same careful manner he did it a moment ago. The orgasm built fast -- what I had just seen was in some ways frustrating, but it was overwhelmingly sexy seeing my brother in the throes of pleasure.
When the climax hit, I came harder than expected, thighs tightening around his head with waves lasting long enough that I had to remind myself to breathe. Afterward I lay still, dazed, while he rested his cheek against my thigh. I ran my fingers through his hair in one long stroke.
"Thank you," I said quietly. "For that. And for finishing on me this time."
He nodded against my skin.
I eventually sat up and used a dirty T-shirt to clean the long streaks from my collarbone down to my stomach. The evidence of the first round chose this time to make its presence known, forming a warm trickle down my inner thigh. I told Luca I needed a quick shower. He stayed on the bed, still naked, watching me.
When I came back, he was half-dressed. We didn't talk much. I was already fantasising about the next time, and I think he was doing the same.
Sunday afternoon meant the house was full of ordinary noise. Our parents were in the kitchen preparing a slow-cooked dinner -- cupboard doors, clinking cutlery, the low hum of their conversation. Luca and I were on the living room couch "helping" by staying far out of the way. The TV was on low volume.
Luca was half-sprawled with a bent leg, soft bulge on clear display in his track pants. I lingered on it for a few seconds, then reached over and gave it a light, teasing squeeze through the fabric. Exactly the same way I used to ruffle his hair when we were kids.
"Still so easy," I whispered.
Luca shot me a warning look but I ignored it and went in for another touch, slower this time, tracing my fingers over the shape. When he twitched I slipped my hand inside his waistband until I found bare skin, and wrapped around him properly. He was rapidly getting harder so I kept my eyes on the TV while stroking with short, lazy movements. I let my thumb slide over the head every few seconds like it was the most casual Sunday afternoon in the world.
"Sofia--" he tried to form a sentence, but his voice was tight.
"Shh. They're right there."
I gave him two firm strokes, then lighter again, just enough to keep it building. His breathing became rapid and I felt him swell in my fist. A few more firm tugs and he grit his teeth in a low groan. Luca spilled through my fingers, hot and sticky into his pants while the sound of vegetables being chopped echoed from the kitchen.
I wiped my hand on his shirt, then lifted one partially cleaned finger, put it in my mouth, and slowly pulled it out clean like I was sucking icing off my finger. I gave him a satisfied big sister look.
"That's what you get for staring at my chest earlier."
I stood up and walked toward the kitchen to offer help with the salad, leaving him to his mess on the couch.
That night I waited until the house was completely still. At a little after two I slipped out of my room and into his. He woke up the moment the mattress dipped under my weight, but I didn't speak. I spent some time running my hands over his chest, his stomach, the already growing length under his boxer shorts.
"I want to help you last longer," I whispered. "If you'll let me."
I heard the swish of Luca nodding in the dark.
We shuffled around until we were on our sides and facing opposite directions. I took him into my mouth at the same time his tongue found me. The angle was messy but intimate and I enjoyed it more than I expected.
Luca lasted longer than he ever had, by far. Just over ten minutes of slow, careful work gave plenty of time for me to enjoy several small orgasms against his mouth. The size of him made my jaw ache, and I was all too eager to end this experiment early to see if it worked.
I pulled off and rolled onto my back, pulling him over me with a well-executed sacrifice sweep.
"Come here," I said in the softest big sister voice I could pull off. "Inside. It's okay."
He pushed in slowly. The entrance was familiar now but still overwhelming. I encouraged him with quiet words, hands on his back, telling him he was doing well and that it felt good -- I wasn't lying.
"Keep going." It was beginning to feel really good, I was building rapidly.
About five thrusts later, Luca's rhythm broke and I could tell what was coming. I tried to squirm up the bed but the wall was too close and he thrust deep on instinct, bumping his head on my cervix in a sharp, pleasurable-pain jolt. And then he was coming -- the usual thick, heavy strands being emptied straight into me while I held him there and felt every one.
Three, four, five. I counted the pulses of his load -- it was massive and he grew in girth and hardness with each shot. I lost count as a wash of heat covered me and my legs began to shake. Pleasure consumed me for a short moment as an orgasm crept up out of nowhere.
When I regathered my composure, we were still locked together and remained until the last tremor passed. His forehead rested against mine and we lay in silence. The quiet of the house began to reassert itself after our brief, beautiful chaos and the reminder of what we had done settled deep between my legs.
Time felt like it stretched after that night. Mundane weekdays filled the gaps -- Luca would share a bag of chips with me on the couch, the two of us would hide a stupidly expensive pair of headphones from our parents, long afternoons in the backyard pool where the only contact was a light splash fight.
One evening Luca found me in the kitchen and asked, voice low, if we could practise more. I agreed.
We started with very slow missionary. I coached him to go very carefully an inch at a time and pausing whenever I told him to. It was exquisite for me, as I got to feel myself make way inch by inch. His girth made even the smallest thrust intense and I kept my hands on his shoulders to talk and guide him through it. I told him when to push deeper, when to hold still. He managed about ten controlled pumps before his control broke down.
He finished inside me again, forehead pressed to mine, the heavy pulses prominent. Afterwards he stayed half on top of me and played with my breasts the way he had before. Slow, attentive, gentle, even grateful. We fell asleep like that, naked, and only woke when we heard the front door swing loudly open. We had napped for longer than expected and the drunk voices of our parents made us scramble into clothes to pretend we fell asleep with a movie on. Our parents suspected nothing.
A few nights later we tried doggy. I braced on my forearms and let him take me from behind. The angle made him feel even larger, I could barely take it, and he lasted longer this time. When his breathing turned sharp he managed to pull out and finish up my lower back and over the curve of my ass. I stayed in position and asked him to keep going with his mouth. He licked me from behind until I came, thighs shaking.
When I looked over my shoulder he had my sex all over his mouth and chin. I turned, wiped it away with my thumb the way I used to wipe chocolate off his face when we were kids, and then kissed him. Soft, approving, and appreciative.
Afterwards, while we were still catching our breath, I reached into the drawer on my nightstand and handed him the small plastic stick. Two visible lines. He stared at it, then at me, and worry washed over his face.
"Are you angry?"
"No." I meant it. "I'm really not. The sex is... good, Luca. Even when it's quick, it's still better than any of the boyfriends I had. And now that this is happening..."
I ran my fingertips over my stomach lightly. "I don't want to keep stopping. I want to be available. For you. Whenever you need it."
Luca looked at the test again, then back at me. The worry didn't disappear, but acceptance joined it. And his eyes flashed with a hunger I will never forget.
I took the stick from his hand and set it aside before pulling him down into bed with me, letting the new reality settle in without the need for further discussion. Free use had just been offered and I was excited to see what it meant.
A few nights later the house returned to its usual deep quiet. I heard our parents' bedroom door close and the last of the hallway lights click off. Not long after, the mattress dipped.
Luca climbed over me in the dark. He stopped between my legs and hovered there, the thick head of him resting against me but not pushing in. His voice was low.
"I don't want to practise tonight. I just want to enjoy you."
I reached down and wrapped my fingers around him once, feeling how hard he already was.
"You can do whatever you like."
He pushed inside me in one stroke until he was as far as he would get. We stayed still for a moment, breathing the same air. The thickness of him felt different now that I was already pregnant -- more claiming. He kissed me once, soft, then began to move in long, slow thrusts.
It stayed gentle for a while. Intimate. The quiet sounds of the house around us, the faint creak of the mattress, the wet squelch of a brother enjoying his sister's excitement. Then he slid one forearm under my shoulders, gathered me closer, and changed the rhythm. Deeper. Harder. Faster. Each thrust landed with force, the head of him brushing that sensitive place at the end of me. I wrapped my legs around him and held on, staring with love deep into his eyes. It hurt, but it hurt for him. He needed this.
He lasted longer than he used to, especially considering the faster pace. He drove in deep and dropped his load into me with heavy, pulsing waves. I kept him there through every one, hands on his back and fingernails applying light pressure, letting him finish completely.
When it was over he stayed inside me, weight resting carefully on his elbows, face turned into my neck. The new arrangement needed no further discussion. He had taken what he wanted, exactly as I had offered, and I had given it without hesitation.
Eventually he slipped free and settled beside me. I stayed on my back, one knee still bent, feeling the slow warm leak of him between my thighs as I covered the bridge of his nose in soft kisses. His hand rested on my stomach as we drifted off, already past the point of pretending this was only practice.
The afternoon was already warm when I stepped out of my room in my bikini, phone in one hand, towel over my shoulder. Luca was in the hallway pulling on his board shorts. Through the open back door, I could hear the scrape of the BBQ lid and our parents' voices. Dad was asking where the tongs were, Mum was answering from the kitchen.
Luca looked at me, then toward the backyard, then back at me. He was already half-hard.
"Please," he said quietly. "Just quick. I'll be fast."
I hesitated, listening to the clatter outside. The risk was very real. Then I sighed, slid a finger in the side of my bikini bottoms, and pulled it aside.
He stepped in close, pushed himself against me, and slid in with almost no resistance. Three short, urgent strokes and he bucked hard as he emptied into me. I bit my lip and stayed completely still until the last throb faded. When he pulled out, I fixed the bikini back into place.
We walked out to the pool a minute later like nothing had happened.
Dad handed Luca the tongs. Mum asked me to grab the extra plates. I sat on the edge of the pool with a drink, the sun on my bare shoulders, and felt him begin to leak out of me. Every small shift of my hips reminded me. Across the water Luca caught my eye once and looked away again, the same secret existing in two worlds.
I floated on my back for a while, staring up at the clear sky, and let the thought wash over me for the first time.
I was pregnant with my brother's child.
Sooner or later, I was going to have to tell our parents.
The smell of the BBQ drifted over the water. Family noise filled the backyard. Between my legs the evidence of what we had just done continued its slow, private escape, and I floated there, already pondering the first cautious versions of a conversation I did not yet know how to begin.
