step-Mom comes into your room, and says that the contractors working on the upstairs turned off all the heat! step-Dad's taking the couch, can she stay with you? "Just for tonight? I know, you finally get your own room and here I am, invading your privacy!" she says, but you don't mind. Until, of course, you pop a boner while you're both in bed, your cock hard as a rock looking at the form of her under her pajamas. She's beautiful, you've always known that, but...having her body rubbing against you, god, you really shouldn't but you can't help yourself. You start to slowly rub yourself against her, grinding just a little, so you don't wake her. After a little bit, though, she starts to push back. Not push you away...push back, into you. You can't believe this, but you think she might be into it! You can't believe how badly you want it, and when she finally reaches behind her, tentatively grabbing your cock, you nearly explode! "We really shouldn't do this," she says, glancing at the partially open door that leads to the living room, where step-dad is on the couch. His close proximity only makes you harder. You never would have thought this would turn you on so much, but the idea of fucking his wife--your step-mother!--right under his nose has you so hard, and your step-mom is egging it on. "What would he do?" she asks as she positions herself beneath you, begging you to fuck her, to make her your slut!
