Once there, she sheepishly asks if you want to masturbate together, and you agree. You have to be quiet as not to alert your stepparents downstairs, but it seems like harmless fun… Just two people getting off - until her boyfriend calls her wondering why she stopped responding! Soon her and her boyfriend are having phone sex, and your stepsister gets even more turned on than before. She can’t help it… her fingers aren’t enough. She’s so horny that she starts to perform the sex acts on you as she describes doing them to her boyfriend.
She massages and sucks your cock, shushing you and nodding as if to say it’s okay. Before long she’s climbed on top of you and your cock is burried deep in your stepsisters pussy! She rides you cowgirl, then flips over to doggy and finally you put her onto her back and watch her beautiful tits bounce around as you fuck her missionary, and when her boyfriend gets close to cumming so do you, and you end up giving her a huge creampie! Your stepsister, still on the phone plays it cool and ends the call with her boyfriend, but then gets upset with you for cumming inside of her - she’s not on any birth control! Your grumpy but satisfied stepsister tells you you should probabaly leave so she can get cleaned up - hopefully your stepparents didn’t hear you!
