Hinako joined a gym to get the body type her husband would like. The trainer is an ass man and gets heated up during instruction. Hinako is drenched in sweat and love juices from the sexual harassment training. Unable to hold back his desires, the trainer assaults Hinako. Although she should feel repulsed, the trainer's incredible dick is just too amazing, making her experience unprecedented orgasms and squirting! Especially the reverse piston action is the best; she awakens to the pleasure of being penetrated from behind. While feeling guilty towards her husband, Hinako still goes to the gym every day seeking intense pleasure and getting taken.
