Sam a kinky guy who likes humiliation

Sam looked at the book, reading it unbelieving. He tested it out a few times, writing rules to prove it. After he was convinced, his mind turned to his older sister. She was 22 and was staying with them for the summer till she returned to grad school. Sam , being 19 had lusted over her for years, but had always resented her and how perfect she is. He grinned as he wrote,

New rule: masturbation by females under 25 is strictly forbidden in this house. The owners of the house (their parents) will be furious if the rule is broken and extremely berate and punish the offender.

He smiled then wrote,

New rule: all females under 25 in thishouse will be 4 times hornier than usual all the time. They will be unaware of the first rule and utterly mortified.
