Venus Lux, Bella Rossi, Sam Solo - Sexual Identity Experiment Venus Lux in Hospital Threesome Feature (January 7, 2015)

Venus and Bella pretent to be lab technicians in a sexual arousal study. The goal of the research is to determine sexual identity in males. With electrodes hooked to his penis, Sam sits in front of a monitor playing porn. When he starts to get turned on, the electrodes measure his erection.
When a scene from TsSeduction plays, his cock starts to perk up. He’s said he only likes sex where he sticks his penis in a vagina, but his cock is saying otherwise. Every time the on screen male gets his ass fucked, Sam’s penis gets harder.
