It was wrong to think about your stepmother as you did. She’s your father’s wife, for God’s sake. It’s terribly immoral. But you didn’t let that stop your fantasies from running wild. When she bent over, you always thought of grinding up against her ass, or when she wore pants that framed her dick perfectly, fuck, did that have you soaked.
But even though you so desperately wanted to shove up against the wall and make out with her, you hated her.
“Fuck you, Agatha! I’m an adult, for fuck’s sake. I can make my own fucking decisions,” you screamed, face hot.
Agatha’s eyes rolled. “Did you just learn to swear?”
You glared at her, arms crossed over your chest. “I’m going to the party.”
Agatha stood with her hands on her hips and her lips tight. “I promised your father I would look after you whilst he’s gone, and going to some trashy college party is not safe!”
You swiped your keys off the counter and tried to push past her, but Agatha grabbed your wrist and pinned you between herself and the counter. You knew the act wasn’t purposefully sexual, but you could feel her dick pushing against you as she kept you trapped. Your heart sped up.
“You are not going, do you understand, mommy?”
You swallowed, pussy clenching around nothing. Agatha has been trying to get you to call her "mommy" and "mama" for the past few months. You refuse to. Not because it weirded you out or anything, but because you knew that if you did, it would only fuel this sexualness you have for her.
“Uh-” you stuttered.
“Do you understand?”
“Yes,”
“Yes, who?”
You hesitate for a moment, the word nearly slipping out. “Yes, Agatha.”
She seemed disappointed, but she took your keys from your hand and stepped back. You headed to your room, the thought of the party leaving your mind as all you could focus on was the throbbing feeling between your legs and the need to relieve yourself.

Your fingers worked relentlessly, pumping in and out of your soaked pussy. The sheets below were damp with your wetness and sweat. You groaned in frustration, eyes welling with tears. For the past two hours, you have been edging yourself. Nothing will bring you over that edge, and you’ve tried absolutely everything. Well, not everything.
I can't, you tell yourself, it’s wrong.
You checked the time; it’s 12 AM, way past Agatha’s bedtime of 10 PM. She’s a heavy sleeper, so she probably wouldn’t even wake up. Does that make it better or worse? Before you can question yourself about the morality of the situation, you’re slipping out of bed and down the hall to their shared bedroom.
The door was already cracked open, revealing Agatha’s sleeping form in the moonlight. Her white night gown had risen over her hips as she slept. She wore pink heart panties. Cute.
You sneaked into the room, settling into the longue chair in the corner of the room, which faced the bed. You spread your legs, slowly dragging your fingers through your folds, collecting your slick. You covered your mouth to muffle your moans, your fingers gliding into you. It felt good, so fucking good being able to watch her whilst touching yourself, but it wasn’t enough.
You slowly clambered over Agatha, hovering right over the place your body begged for. You pulled her panties down, watching her face cautiously for any signs of waking. Her dick sprang out, and you swallowed nervously. She was way bigger than you expected. That wasn’t going to stop you, though.
You brushed your finger over her hole, and she twitched. As you slowly started to jerk her off, she stirred. Her eyebrows furrowed, and her lip got caught between her teeth. You thought she was going to wake, but she didn’t. Her pre-crum drizzles from the head down her shaft, and you moaned as you licked it up.
“Messy, aren’t you, mama?” you mused.
She whimpered, and your pussy ached for more. If she didn’t wake up to you giving her a handjob, no way she would wake up to you riding her, right? Yeah, sounds right.
Oh, how you were wrong. Your pussy has swallowed half her dick, your walls fluttering around her, and tears streaming down your face from the pain of the stretch when she wakes.
“Shush, shush. It’s okay, Agatha,” you hushed her as she let out a noise of confusion mixed with a moan. “I just need this, yeah? It’s okay.”
“Y/n? W-what are you doing?” she questioned with a heavy breath. Is she close already?
You grabbed her face, kissing her deeply and moaning into her mouth as you took her whole length. The kiss was fierce and desperate. You clashed for dominance, tongues pushing against each other, but she was crowned victor when she flipped you onto your back.
“How long were you-”
“Please, mommy, please.”
It was like hearing that snapped something inside her. Her hips slammed forward, her grip on your thighs iron and no doubt will bruise. She moaned, her head dropping onto your shoulder. You wrapped your legs around her waist, pulling her closer to you.
“I can’t hold for long,” she whimpered.
“Please, don’t. I just need you to cum in me, please.” You know you were begging pathetically, but you didn’t care.
She bit down on your shoulder as she came, her body shaking. You followed shortly behind, your back arching and eyes squeezing shut. You threaded your hand through Agatha’s hair and kissed her softly.
Suddenly, the situation dawned on you, and you cleared your throat awkwardly. Agatha did the same, removing herself from you. You stand, legs shaking from your orgasm.
“Um, goodnight, Agatha.”
She smiled softly, but sadly. “Goodnight.”
You hurried back to your room, mind racing. No fucking way did you just let your stepmom fuck you. But even though it was wrong, you didn’t hate it. In fact, you loved it enough to let it happen again. No harm if your father doesn’t find out, right?
