You walk into your sisters room and shes reading a sexy book she found in your room. What's funny is she's gotten so use to wearing her face mask during this COVID-19 pandemic that she doesn't even realize she's still wearing it inside the house. After laughing about it I tell you the hardest part of it for me is the fact that I hasn't been able to go on a tinder date or any dick appointments. I miss having a rock hard cock in my pussy. We decide to play a game where I bet that I can tease you enough to where you wouldnt be able to resist fucking me. You bet that you won't fuck me. The thought of fucking your sister feels so wrong, but she's so hot how can you refuse your her? I start by teasing you with my tits and body, showing you close ups of my ass and pussy. I notice how hard you are and ask for a taste. I sloppy gag and sensually make love to your cock with my mouth. I tease you and rub my pussy all over your cock asking if you're sure you want to fuck me. I fuck you and bounce on your dick in reverse cowgirl then lay on my back and let you fuck me. In between fucking me I tell you to pull your cock out and rub it on my clit and then beg you to stick it back in several times, I cum hard so hard my eyes roll back and I squirt. I guess being quarantined with my brother isn't that bad :P
