[ Episode can be enjoyed individually, or as part of the full series ] In the second installment of A Taboo Experiment, you and sister 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 sister’s ass under her school uniform skirt at the dining table with mom and dad right there. Once mom and dad have evacuated to the neighbors’ for happy hour, sister 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, sister sits on your lap and stuffs her pussy with your cock - but she barely gets started with you when mom and dad come through the door. Awkwardness ensues when mom wants to know what the hell is up with sister sitting on your lap, and more generally, what’s up with you guys hanging out all the time now. Thankfully, mom doesn’t notice that your cock is deep in your sister while she talks to you, so naturally you sneak upstairs to finish up once she’s gone. Sister 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 sister (her first one during sex), she’s so cockdrunk she says fuck it and you cum inside her once again. We end on sister hanging with you while you game, confiding in you that she’s late on her monthly cycle and she’s panicking a little. Approximately 10 minutes of this video are sexually explicit (blowjob/penetration/etc).
