Chapter 20: Showering Together
I turned around abruptly, giving her my back before her eyes could continue tracing my body. My breathing was erratic and I could feel my cock growing even harder, throbbing with a painful stiffness. I needed to calm down, I needed the cold water of reality to hit my mind, but the steam in the bathroom only served to fuel my most basic instincts.
"Why did you come in, Ava?" I asked, trying to sound authoritative, but my voice came out rougher and more broken than I intended.
She ignored my question. I heard the hiss of the sliding door closing and, right after, the sound of soft footsteps approaching on the wet floor.
"We have to save water, big brother," she said in that sweet voice that hid an intention I couldn't quite decipher. "Besides, I'm much shorter than you. If I stand in front, the water will reach me better and we won't waste any."
Before I could protest, I felt her pass beside me in the narrow stall. As she did, her naked body brushed against my arm. It was barely a second, but I felt the warm, soft weight of one of her breasts against my skin. The sensation was like an electric shock that ran down my spine. I took a step back by pure reflex, but my back hit the cold wall of the shower; there was no more space to escape.
I cursed mentally. "I can't do anything now," I told myself, resigned. The best thing was to finish showering as quickly as possible to escape this torture. I let her pass and she positioned herself right in front of me, with her back to me.
I tried to look at the ceiling, at the walls, at anything that wasn't her, but my height worked against me. From my position, the view was inevitable and my mouth watered. The water cascaded over her shoulders and slid down her back until it disappeared into the curve of her ass cheeks, but what disturbed me the most was the frontal view I got when I leaned a little: the water hit her heavy breasts, drawing shiny trails over her pale, milky skin. Her nipples, hardened by the temperature contrast, stood out with a lewdness that burned my eyes.
My cock reacted instantly, jumping hard. I had to arch my hips backward, pressing my ass against the wall to avoid my erection brushing against her round, firm ass, which took up almost all the space between my legs. I felt dangerously aroused; the heat of her body and the scent of her soap were driving me crazy.
"The water feels so good…" she whispered, letting out small moans of satisfaction that made my hairs stand on end.
"She's your sister, don't look," I repeated like a mantra, suffering mentally. She was my little sister, yes, but she had a body to die for that I found impossible to ignore. Naked, wet, and moaning under the water… it was a test my rigid upbringing hadn't prepared me for.
I decided to focus on my own hygiene. I grabbed the shampoo and started lathering up with quick movements, trying to ignore her presence. I saw her let her hair down; her silver mane spilled over her back like a cascade of silk. She began washing her hair, humming a soft melody, acting as if I wasn't about to lose my mind right behind her.
The calm was only an illusion.
"Little brother…" she said sweetly, turning her head slightly. "Will you wash my back? I can't reach well."
She looked at me over her shoulder, soap in hand and those big, wet eyes that disarmed me. I froze, my heart hammering in my ears.
"Ava, I…" I stammered, feeling nervousness run through my body.
"Please…" she insisted. Without giving me a choice, she took my hand and placed the soap in my palm.
I hesitated for a second, but tried to convince myself: "It's just her back, I can handle this." Gathering courage, I lowered my hands onto her wet skin. I started making circular movements, spreading the foam over her beautiful back, which narrowed elegantly down to her waist.
"Mmm… that feels so good," she let out, and that moan hit me like a direct blow to my crotch. I felt my cock throbbing painfully, pointing toward the sky, wanting to break free from the pressure.
"Here too," Ava said, gesturing with her head toward her lower back.
In my mind, I was still fighting the feeling of being a pervert. I made sure to wash thoroughly, but when I reached the lumbar area, my eyes landed on what seemed like sacred territory: those large ass cheeks that jutted out lewdly, shining under the water. I quickly moved my hands back up, fearing that if I went an inch lower, I wouldn't be able to stop. I was getting more and more aroused, my breathing becoming heavy.
But then she called me again. Suddenly, her small hands sought mine and, with a softness that left me breathless, she guided them forward, wrapping around her body.
"Here too…" she whispered over the sound of the water.
She pulled my hands until they landed directly on her large breasts. I froze completely, feeling my brain short-circuit at the contact with her soft, firm skin. I felt the full weight and warmth of her tits in my palms; it was an intoxicating sensation. I noticed Ava's ears were red and strands of her silver hair stuck to her neck from sweat and steam.
Was she deliberately provoking me? I couldn't avoid thinking about it.
I started reviewing everything that had happened since I arrived home: how she sat on my lap during dinner, how she slept naked with me in the same bed, and now this. I didn't know if it was my imagination or if my little sister had really become a living temptation. I regretted not leaving the moment she entered, but it was too late.
"I already touched them by accident before, I'm just helping, it's just putting soap on…" I tried to lie to myself, but I no longer believed it. My fingers moved on their own, spreading the foam over the lower curve of her milky breasts, while I felt my own breathing becoming deep, fast, and hungry.
