I just started living with my step-brother, George. I'm used to walking around nearly naked, but he's never lived with a woman before. While I'm putting on lotion and talking to him, I notice he gets a boner. I laugh and ask him if he likes his own step-sisters tits. I realize he does, and taunt him a little with the thought of the trouble we could get into. Finally, I decide it would probably just be good to jerk off together, and then we won't have to worry about being horny anymore. I show George my tits, teasing and telling to touch them. I show off my ass, asking if he likes his step-sisters big ass. Finally, I take off my panties and spread my legs, moaning for my step-brother and telling him to stroke his cock for me. I dirty talk while I play with myself, and finally end in a cum countdown where we both cum together. I'm sure this will help us not be horny for each other. ;)
