Billy is on speakerphone to his optician when he asks him some very embarassing questions. As his two female flatmates listen in, he is asked if he wanks a lot because it is ruining his eyesight! The girls giggle as Billy turns red when the doctor tells him not to jerk off any more! After the call, the girls are worried for Billy's eyesight and offer to satisfy him so he doesn't jerk off and go blind. They strip him naked and take turns to suck his big cock. He soon cums hard as they tell him to use their mouths anytime he feels the need to wank!
