Your (18) year old sister comes into your room and finds you watching porn. “I feel like I know that girl from somewhere.” Curious, she asks if she can stay and watch with you. “Is it bad that watching this makes me feel really horny? I just can’t help imagining it’s me in the video…” Your sister begins to touch herself, asking you lots of questions. Do you watch porn a lot? Where’d you get this video anyway? When she finds out that both of you are virgins, she gets an idea… “why don’t you take out your dick? I know you were going to jerk off to this anyway.” Suddenly, she realizes where she recognizes the girl in the video from: it’s her friend from school and the guy is HER BROTHER! Compared to what they’re doing in the sex tape, jerking off with her own brother doesn’t seem that naughty now. Hearing this gives you guys a naughty idea. She reassures you that mom won’t be home for another 20 minutes and begins to suck you off. Before you know it, the two of you are engaged in the most taboo thing a brother and sister could do together: your cock, with NO CONDOM, sliding inside your fertile teen sister’s virgin cunt. “I think I’m ovulating but you can pull out right?” She reminds you how bad the “I” word is and how you can UNDER NO CIRCUMSTANCES cum inside her. You wouldn’t want to get your sister pregnant right? The two of you fuck until you hear the front door open. “Oh no, mom just got home!” Your sister gasps, but continues to bounce up and down on your cock. “Shhhh! Shhh I’m so close just let me finish on your cock I NEED IT.” She moans as your mom starts to call out “Hazel? Where are you two? It’s awfully quiet in here.” Mom starts to walk down the hallway and just as she gets to your room you feel your sister’s pussy contract on your cock. You’re so turned on and distracted hearing your mom come home that you accidentally release inside your sister, filling her with warm sticky cum. Your sister is shocked but quickly pulls herself together as your mom opens the bedroom door. “What are you two doing in here?”
