Includes: Taboo, Masturbation, Just the TIP, Virgin, Barely Legal, ENF. Sis got caught wanking by the parents and has been banned from masturbation. Since she's so pure, she's going to follow the rules and not touch herself. But sis gets super horny one day and bro tells her about a loophole in the rules. If bro does it, its not technically masturbation, or sex, so she can still stay a virgin and cum, she just needs a little help. Oh what a wonderful selfless bro for doing this for little sis... It makes alot of sense actually, and mommy and daddy will never suspect a thing.
