When the girls catch their flatmate Mark laughing at some poor girl being humiliated by having naked pictures of her shared around the internet, they decide to give him some of the same medicine. They strip him naked and hold his legs open while they take photos and laugh their heads off. All the prodding and teasing soon has his cock standing on end and the girls laugh at how turned on they have got him. They then take turns to suck his cock before he cums for them - then they hold him down and take more photos!
