You're Not Quitting StepMommy

Stepmommy comes home tired from work and wanting a fuck to let off some steam. Not the perfect moment to confront her with your decision to quit having sex with your stepmother, but it'll have to do. When she realises you're actually serious and arguing her case won't work, she shrugs it off and tells you you'll change your mind. Days later, she sneaks out of bed with your stepdad and comes to see if you've changed your mind. You stand strong but she tempts you into letting her suck your cock, worried that you'll get blue balls if she doesn't. Now that she's got you hard, your resistance is weakening and when she slides you between her legs to give you a thigh job, you're seconds away from letting it all go. But she stops and leaves you. You didn't want this, right? If you're gonna play games with stepmommy, she's going to play them too. The next week, she approaches you dressed in the skimpiest outfit and holding a bottle of oil. She's decided to sack off her exhausting job and take up a career as a masseuse: she'll be home more often and able to spend more time with her boy, but she does need someone to practice on. You reluctantly lay back as she starts massaging those tight muscles, her huge ass in your face and her pussy grinding against your hardening cock. When she turns around and takes off her dressing gown (what? it's getting hot), she "accidentally" sits right down on your erection and you slide into her wet pussy. She rides you until she orgasms, then apologises: your stepdad's going to be home any minute so we'll have to stop there. You didn't get to cum, but you're trying to stop all this so it's for the best, right? Another night, she shows up in your room horny and practically begging you to fuck her it's been so long, but you stay strong. You think she's given up when she comes back in dressed in slutty lingerie and dripping with oil. She takes out your cock and begins sucking you, keeping you on the edge, stopping each time you're about to cum. You're controlling yourself so well, why not just slide it in for a bit? She rides you and tells you to fuck her in all positions and you can't resist. You make her cum multiple times but just as you're close, she calls it a night. The next week she sits down with you as you're checking your calendar. You might not have successfully quit her cold turkey, but you're proud that you haven't cum inside your stepmother for weeks now! When she realises you've been keeping track, she decides enough is enough. This is all just silly. She takes your cock out and sliding it between her big tits, convinces you to just give in. It's what you both want isn't it? Why deny yourself. Your resolve finally broken, you take her upstairs and fuck her, unloading the biggest load all over her chest. Your cock stays hard, your balls full from weeks of denying your urges and she rides you, your cum dripping off her tits as she begs you to breed her. She knew you couldn't stay away, now she wants to make up for lost time and get impregnated by her stepson...
