incest

Incest is taboo but extremely aroused. It's easy for people to cum while masturbating with porn but it becomes terribly easy while you think you were fucking your family members (son & mom, dad & daughter, brother & sister). But the best incestous scenario is fuck both your mom and sis.

He fucked his sister in her ass and then put his penis into his mom's mouth. They're such incest family.

I saw my sister undressing, and got a boner, does that mean we did incest?
