My parents remarried and I started living with my sister-in-law. She's a vulgar, slutty sister-in-law who calls me a virgin and teases me! But she's surprisingly kind and doesn't discriminate based on my appearance. She doesn't put up any walls between her and anyone, and she tells me things like, "I can't help it, just take out your dick," and she tries to teach me sex and treat me like a sex friend. Naturally, I can't resist my naughty sister-in-law and I fuck her raw over and over again! I cum inside her over and over again!
