A TABOO FLIRTATION

In the second installment of A Taboo Series, you and your STEPsister have been sneakily having sex for a while now and have developed a habit of teasing and touching each other around the house to try to turn each other on. We open on you making an attempt to touch STEPsister's ass under her school uniform skirt at the dining table with your STEPparents right there. Once they've evacuated to the neighbors’ for happy hour, STEPsister decides she’s in a mood to tease the hell out of you while you play video games on the living room couch, lap dancing on you until you’re hard, then suggesting you continue gaming while she sucks your cock. Unsatisfied that she can’t sufficiently distract you with her mouth, STEPsister sits on your lap and stuffs her pussy with your cock - but she’s barely gotten started bobbing up and down on you when your STEPparents come through the door. STEPsister has no choice but to sit all the way down on your lap, your erection deep inside her as she greets your STEPparents. Awkwardness ensues when STEPMommy wants to know what the hell is up with STEPsister sitting on your lap, and more generally, what’s up with you guys hanging out all the time now. Thankfully, STEPMommy doesn’t notice that your cock is deep in your STEPsister while she talks to you, so naturally you sneak upstairs to finish the deed once she’s gone. STEPsister asks you not to cum in her this time since you’ve been doing it a lot, but once you fuck an orgasm out of her (her first one during sex), she’s so cockdrunk she says fuck it and you cum inside her once again. Once you’ve cleaned up, STEPsister hangs out with you while you game, confiding in you that she’s late on her monthly cycle and she’s panicking a little.
