Stepmother's Service
"...That should about do it."
The counseling room still reeked of sex, but every filthy puddle of juices on the floor had been wiped clean with wet wipes. No one was going to come in here anyway—leave the door open on the way out and the smell would clear on its own.
I glanced over at my stepmother slumped across the table. She was still gasping, trapped in the aftershocks of her climax, sweat gleaming on her skin as cum dripped steadily from between her ass cheeks. The sight of her was unbearably hot.
The only real question left is how she's going to play this...
Honestly, the odds of her telling anyone were vanishingly small. She was prouder and more hard-headed than anyone I knew—and she hadn't exactly been innocent herself, treating me like a slave and putting me through every kind of humiliation. If this got out, we both lost.
"...Don't you think you should get up soon? You can't just stay like that in the counseling room."
I spoke first, perfectly casual. Only then did it hit her that we were still at the academy. She bit down hard on her lip and glared at me.
"...You. When we get home, you'd better be ready."
"If you've got something to say, say it here."
"You think you can do that to me and just walk away?"
I snorted.
"Do what, exactly? Catch your stepson by the balls and try to turn him into your slave?"
"......"
That finally sank in—she was in no position to lecture anyone. Color flooded her face. She had used me as a sex slave to feed her own filthy need for conquest, hadn't she?
And because she chased perfection harder than anyone alive, the moment this got out, every scrap of social standing she had built would come crashing down. That much was obvious.
"...Tsk."
She clicked her tongue, face tight with fury, and started gathering her white blouse and stockings off the floor. The sweat stains were impossible to hide, but once she had the suit back on she looked every inch the haughty teacher again.
Glasses perched just so, expression locked into something crisp and professional—no one looking at her now would ever guess she had been writhing under me minutes ago, screaming her head off.
Which, of course, only made it hotter....
"......Heading home now?"
"Why do you care?"
"Give me a ride. You're going home anyway."
"Get lost."
The answer came instantly. In the end, I walked.
After that day, everything between my stepmother and me flipped one hundred and eighty degrees. How to put it... We still couldn't stand each other—but physically, we had become closer than anyone.
"Welcome home, Mom."
"I'm exhausted today, so don't even think about—"
"Kyaah!?"
I caught her by the arm the second she walked through the door. She still had her heels on. She thrashed in my grip, but strength was never going to save her. I hauled her straight into the living room, shoved her down on the sofa, and started stripping her clothes.
The moment my fingers went for the buttons of her blouse, she shoved at me with her stockinged feet.
"You fucking pervert! Stop it....!! I just got home—I'm tired....!!"
"Hold still. I'll make you feel good."
She fought at first, but the second I started licking the nape of her neck just right, she gradually went quiet. All that snarling was pure pride. She couldn't stand admitting she was losing her mind to the pleasure, so she put on a show of resistance.
As if to say, I'm only letting this happen because I have no choice!
Proof enough: the moment I pinned her down by force, she would quietly spread her legs like she had already lost, looking up at me with an expression that was already hungry for whatever I was about to give her.
"Relax your ass."
I said it as I peeled off her panties and set my hands on her hips. I kneaded those soft cheeks, then casually pressed a fingertip to her asshole. The second I started rubbing the rim, her toes curled and a moan slipped out of her.
"Hnnnnh...."
"You like it when I touch your shithole?"
"Don't talk like that...."
The crude word twisted her face. True to that haughty personality, filthy language still made her flinch. Which was exactly why I kept using it—the more it shamed her, the better.
"Nngh.. hnnngh...."
A dirty little anal slut through and through. Circle her asshole and she melted. She was biting back the sounds, but that strained look on her face only made me harder. All the work I had put into training her back door was paying off—even a light touch got a reaction now.
"See? You're feeling it through this hole."
"Shut up..!!"
"You'd be better off just admitting it already."
My tone was mocking, but my hands stayed gentle. The goal was to break her, so I made damn sure she felt good doing it. I wanted a bitch addicted to the pleasure I gave her. I spread her ass wide with both hands.
"Alright. Relax for me..."
"Hnnnnnh....!!!"
The second my finger touched her asshole again, her brows knotted.
"Th-there—don't..!!!"
"Just the tip. Aren't you curious?"
"Th-that's...!! Haaahn...!!?"
The idea of something going into her ass clearly freaked her out—she clenched hard, sealing the entrance shut. I put steady pressure behind my middle finger and slowly pushed it in anyway.
"Ugh? Jesus, it's tight..."
Her asshole clamped down like it had been waiting for this, locking onto my finger and refusing to let go. Hot inner flesh squirmed and squeezed around me, and a thought flickered through my head. If a finger felt like this, what would it feel like to put my cock in?
...Save that for another day.
Right now, the priority was sending her home happy.
I worked my finger slowly, teasing the inside of her back hole.
"Hup..!!? Haaagh...!!?"
Squish, squish, squish....
As my finger stirred her sticky insides, her back arched and her whole body shuddered. Her ass was still so tight it could barely take a single finger, but bit by bit it softened, going pliant and giving me room to move. I stroked the sensitive flesh inside her, patiently guiding her toward the edge.
Not many people get off from their ass. But I had spent a long time working on hers, and she had been weak there from the start—so now she was curling and uncurling her toes with the filthiest look on her face.
"Hnnngh... not thereee..!!!"
Even as she said it, her hot little shithole-pussy kept wriggling around my finger. I kept the rhythm gentle—then suddenly ramped up the speed.
Squish squish squish squish!!!!
"Getting finger-fucked in the ass and reacting like this... You're definitely a pervert, Mom. What would your students think if they saw you now? A dirty slut who cums from getting her shithole reamed—they'd despise you, wouldn't they?"
"I'm not... shut uuuup..!!"
That proud face had completely fallen apart. The last thread of reason had snapped. She rolled her smooth hips and sprayed pussy juice in every direction, then spread her thighs wide in a perfect V, baring her crotch completely, face gone slack with bliss as she braced for the orgasm rushing up on her.
"Hnnnnnh!!!!"
Holding that filthy pose, she screwed her face up like she was trying to hold something back—and the gap between that stupid, ruined expression and her usual icy composure was so huge it was almost funny. It only made me harder. If I snapped a photo of that face and showed it to her later, she would die of shame.
But right now she didn't have the bandwidth to care about any of that.
Because she had started squirting from her pussy, tipping over the edge.
"Cum from your shithole!!"
"Haaahn..!! I'm cummiiing!!!"
I pumped my finger hard and fast, and she finally broke, climaxing hard. Her asshole clenched down viciously at the same time, strangling my finger. The soles of her feet, pointed at the ceiling, went white and wrinkled like she had a cramp.
She kept spraying juices everywhere for a long time. Only after she finally dropped her head against the sofa did I slowly pull my finger free.
"You came ridiculously hard..."
Day by day her reactions only got more extreme, and I felt a deep satisfaction watching it. At the same time, something felt a little off-balance.
....Isn't this a little one-sided? She's the only one getting off here.
Exactly. She could say she hated it all she wanted, but every time I touched her she came apart with pleasure. She was the one walking away satisfied. Watching her cum like a filthy slut scratched the conquest itch, sure—but it did nothing for my own body.
Didn't I deserve a little service of my own to even the books?
The thought barely formed before a perfect idea hit me.
"Mom."
"Hnnnnn... nngh.!!?"
I sat down on her face, pinning her under my ass. She thrashed for a second under the sudden weight—then my next words made her freeze in pure panic.
"I make you feel good every single day, playing with your asshole. Don't you think you should return the favor?"
"W-what are you even....!!"
"God. You're so slow on the uptake."
I settled my full weight onto her face and crushed her under me.
