My little sister, once the schedule for sex is set, she thoroughly engages in abstinence until that day. Of course, her breasts are off-limits until the day of sex, even her nipples get the 'denied' treatment, and she brings her erotic peak to the max right before sex, suddenly exploding with lust! The ultimate abstinence play! Long-term teasing for masochists! You won't be allowed to touch my rock-hard dick anytime soon!
