Step-Mom catches you in your step-sisters room. You know she doesn't like you in here. You try and distract her by asking how her visit went at your aunts but she seems uncomfortable with your question. She immediate tells you nothing happened which is very odd since you never asked that. She is embarrassed to tell you since you're her step-son but... she... saw something when she went there. Something she didn't understand at first. But she witnessed them, a step-mother and step-son, her step-sister and nephew, committing.. she can't even say it. Sex. They were having sex. She starts touching herself, she can't help it. She's so aroused by what she saw. That illicit act. She can see you're aroused too. It's so wrong. It's impossible. But maybe if you just, take the cock that she made out. Maybe if you admit you're just as turned on by this forbidden fantasy as she is. She takes you into her mouth, on your step-sisters bed. It makes it even more wrong and you're both even more turned on. Is that what you were doing in here? Your step-mom can tell, you were jerking it on her step-sisters bed weren't you? Having illicit fantasies about your very own lil sis. Your step-mom wants you to taste her, feel the pussy that made you. Just like she tasted you. Her pussy is already dripping wet, you tongue fuck her hole until its dripping down to her asshole. You might as well lick that too, get all of step-mommy nice n wet. She turns over and you lick her dirty lil asshole. You get to taste all of step-mommy. She can't take it any longer. She needs your cock inside of her, back where it came from. You slide right in, she's already dripping wet. She pulls a pair of panties out from under the pillows, your step-sisters dirty panties. She smells them. She has you smell them too.. its like your step-sister is there with you. You can smell your step-sisters pussy and it only makes you harder. You cum inside of step-mommy all over her sheets. But step-mom doesn't care, she hopes your sis can smell all that sex all over her bed XO **Contains lots of step-brother/step-sister encouragement.
