Paris has talked a classmate into modelling nude for her art assignment but when he arrives he is horrified to find a second girl there. He has to follow through with his agreement though and he strips off and stands naked as they giggle at him. Unfortunately his dick starts twitching and he developts an erection. The girls laugh and tell him to jerk off while they watch. He is reluctant but when they lift up their school skirts and flash their panties he complies. When they rub each other's pussies he shoots his cum all over the floor!
