"On the faucet!" "On the hat rack!" "On the doorknob!" etc. I encountered my older sister practicing fellatio! The younger brother was excited by the sight of her licking around in a dirty way, and when he was found out to be peeping, he said, "I'll improve more this way," and made himself the practice dummy! The older sister was confused at first, but she gradually started using her tongue in a very erotic way as she felt the hot, hard cock! And not satisfied with just a blowjob, he forced his sister down and engaged in forbidden incest!
