"My ass…?"
Yuiira's eyes widened in confusion and fear as I summoned a thick stream of fresh, sweet whipped cream directly from my magic and began slathering it generously over her tight, virgin-pink asshole.
"Stop—please stop! Not there! That's dirty—!!"
She tried to twist away, but I held her firmly in place, rubbing the cool, aphrodisiac-laced cream deep into her puckered ring with two thick fingers.
The moment the cream was pushed inside—
*BLUUUURP—BLUUUURP—BLUUUURP!!*
A loud, wet gurgling erupted from her belly.
"N-noooo!! Not here—!!"
I scooped her up in my arms and carried her to the private toilet in the back of the shop before she could make a mess on the floor.
"P-please… don't look… I'm going to—!!"
The moment her feet touched the tiles, she lost control.
*BRRRRRT—BRRRRRRRT—BLUUUURP!!*
A humiliating torrent of creamy white whipped cream mixed with her own waste exploded out of her ass in noisy, wet bursts. Yuiira's face burned crimson with shame, but her voice cracked with an unmistakable moan of pleasure.
"Aaah… aaahhh♡"
Even as she emptied herself, her body trembled with unwanted ecstasy.
When she finally finished, I pulled her back against my chest and claimed her mouth in a deep, devouring kiss.
"Mmmnh—♡♡♡"
My tongue forced its way past her lips, tangling with hers in a powerful, dominant kiss. She melted against my strong body, her resistance crumbling as the drug and the humiliation worked together to break her down.
I lifted her again, pressing the fat, throbbing head of my cock against her now-slick, cream-coated asshole.
"It won't fit—!! Something that big will tear me apart—!!"
But her body betrayed her. Thanks to the special aphrodisiac cream, her tight ring stretched obscenely wide and swallowed the massive head with a wet *schlurp*.
"Wha—?! How—?! It's going in so deep—♡"
There was almost no pain—only a hot, overwhelming fullness that made her eyes roll back.
I grabbed her hips and started thrusting, slow and deep at first, letting her feel every thick inch reshaping her insides.
"Uuu♡ Don't move—♡ It's too much—♡"
"Your ass is sucking me in so greedily, Yuiira. You're such a perverted married woman."
"I'm not—♡ I'm not perverted—♡"
But her hips were already rocking back to meet my thrusts. Every time I bottomed out, the head of my cock ground against her deepest walls, turning her asshole into a brand-new erogenous zone.
"Why does it feel so good—♡ My ass is supposed to be dirty—♡ Why is my ass making me feel this good—♡"
"Because you're a natural anal slut," I growled, slapping her ass hard.
*SMACK! SMACK! SMACK!*
Bright red handprints bloomed across her pale cheeks.
"Admit it. You love getting your married asshole fucked by a cock bigger than your husband's."
"I… I don't—♡ Aaahn—♡"
I wrapped one hand around her slender throat and squeezed, cutting off her air just enough to make her pussy gush onto the floor while I pounded her ass harder.
"Say it properly, Yuiira. Tell me whose ass this is now."
"It's… it's yours—♡♡♡ My asshole belongs to you now—♡♡♡ My husband can never have it again—♡"
"Good girl."
I choked her tighter and fucked her with brutal, punishing strokes, the wet *plap-plap-plap* of my hips slamming into her ass echoing through the toilet. Her legs shook violently as another orgasm built.
"I'm going to cum inside your ass. Take every drop like the anal whore you are."
"Yes—♡ Please cum—♡ Fill my dirty ass with your hot cum—♡♡♡"
My cock swelled even thicker. I slammed in to the hilt and erupted.
*SPUUUURT—SPUUUURT—SPUUUUUUURT!!*
Thick, heavy ropes of cum blasted deep into her bowels, so much that her belly visibly swelled. The sensation pushed her over the edge.
"I'm cumming—!! From my ass—!! I'm cumming so hard—aaaahhhhh!!!"
Her asshole spasmed wildly around my cock, milking me dry while she squirted violently onto the tiles.
*PSHHHHHH!!*
When I finally pulled out, a thick waterfall of cum poured from her gaping, ruined asshole.
But the drug was still raging through my veins. My cock stayed rock-hard.
Yuiira looked at it with hazy, desperate eyes.
"Nooo—♡ Don't put it back in—♡♡♡ I'll become addicted to ass sex—♡♡♡"
Too late.
I lifted her legs high, folded her nearly in half, and drove back into her cum-filled ass in one savage thrust.
"Too late, Yuiira. You're already my anal-only slut now."
"Yaaah—♡♡♡ My ass… my ass is falling in love with your cock—♡♡♡ I can't go back—♡♡♡"
I fucked her mercilessly—choking her throat, slapping her bouncing tits, pinching and twisting her swollen clit while I railed her asshole raw.
"Whose hole is this?"
"Yours—!! It's your personal cumdump asshole—!! Fuck it harder—♡♡♡ Slap me— choke me— ruin me completely—♡♡♡"
*SMACK! SMACK!*
I rained heavy slaps across her ass and tits, leaving her skin bright red while my cock battered her deepest parts.
"You're going to cum again, aren't you? Cum from getting your married ass destroyed."
"Yes—♡ I'm cumming— I'm cumming again—!!"
She squirted hard a second time, her whole body convulsing as I pumped another massive load straight into her guts.
We continued like animals for hours. I took her in every position—bent over the sink, pressed against the wall, riding me reverse cowgirl so I could watch her gaping hole swallow my cock over and over. Every time I filled her, I made her thank me.
"Thank you for ruining my ass…♡ Thank you for making me your anal slave…♡"
By the time the drug finally wore off, Yuiira was a broken, cum-bloated mess—asshole permanently stretched into a lewd, cum-leaking gape, body covered in handprints and sweat, face shining with tears of overwhelming pleasure and shame.
---
The next morning I dropped to my knees and bowed deeply.
"I'm truly sorry! The magic went completely out of control!"
Yuiira, still walking with a slight waddle, blushed deeply.
"…It's fine. You said it was a magical accident… and you did blow up a wall before, so…"
She couldn't meet my eyes. Every time she shifted, a fresh trickle of my dried cum leaked from under her skirt.
But the real problem was far worse.
Later, when she tried to use the toilet normally, the moment anything touched her asshole she moaned loudly and nearly came again.
"Ah—♡ Aaahn♡ My ass… it's turned into a sex organ…"
Two days. That was all it took.
She couldn't resist anymore.
Yuiira came to me, eyes wet with desperate need, and clung to my chest.
"…Please take responsibility."
"Are you sure?"
"My pussy is still off-limits… but my ass… please use my ass whenever you want…"
I didn't hesitate.
I summoned more of the special cream, cleaned her out thoroughly, then bent her over the same table and slammed my thick cock balls-deep into her greedy asshole once again.
"Oooooohhhhh♡♡♡ Yes— that's it—♡♡♡ Your huge cock is grinding against my insides—♡♡♡ It feels so good—♡♡♡"
Her usual slow, drawn-out speech was completely gone. She spoke fast and needy, completely lost in pleasure.
I grabbed her throat from behind and choked her while pounding her ass with deep, brutal strokes.
"Tell me again, Yuiira. Whose asshole is this?"
"It's yours—!! My married asshole belongs only to you—♡♡♡ Fuck it harder— slap my ass— choke me while you breed my guts—♡♡♡"
*SMACK! SMACK! SMACK!*
I spanked her mercilessly, turning her cheeks cherry red while my cock rearranged her insides.
"I'm going to cum—!! Fill my ass again— pump your hot cum deep into my belly—♡♡♡"
I roared and unloaded another massive load, flooding her until her stomach bulged noticeably.
The pleasure was too much. Yuiira screamed in ecstasy and squirted violently once more.
"I'm cumming—!! From my ass again—!! I love ass sex— I love your cock ruining my asshole—♡♡♡"
Completely overwhelmed by happiness and pleasure, she passed out in my arms with a blissful, fucked-stupid smile on her face.
From that day on, Yuiira became my secret anal-only lover. Her pussy remained faithful to her distant husband, but her ass… her ass belonged to me completely.
