Riho Shishido, A Big-breasted Wife Who Falls Into The Trainer's Womb-evading Back-piston And Goes To Be Cuckolded Every Day.

The fifth installment features Riho Shishido with big breasts and a big ass! She resists her trainer's sexual harassment lessons, saying 'I'm a married woman!' but experiences climaxes she's never felt before with muscle piston thrusts! The back piston is especially intense, and she convulses in ecstasy, sweating and squirting from the pleasure of having her womb gouged! This big-breasted wife, who never came once with her husband, goes crazy orgasming repeatedly, and her rationality collapses as she's filled deep in her vagina with semen (protein) from someone other than her husband! Drowning in pleasure, Riho continues to visit the gym for cuckolding, ignoring her worried husband.
