The local slut of a sister-in-law is always careless, constantly flashing her panties, cleavage, and nipples! It's too stimulating for a virgin like me, so I can only keep my distance. But she invades the bathroom to close the gap! Naturally, I get an erection, but she greedily latches onto it like the slut she is! She even says she'll teach me sex and lets me penetrate her! Even when I cum inside her, she doesn't get mad; instead, she gets more aroused from the internal ejaculation, arching her back and screaming in orgasm multiple times, demanding more internal ejaculations!
