Doctors Lola and Lilly are conducting clinical trials into a new formula which helps men get stronger and bigger erections. Today they have a volunteer coming in so they can study its effects. The poor guy didn't realize he would have an audience and is very embarrassed as he has to strip off in front of them. As the pill takes effect his cock becomes erect as they stare at it. The sexy girls then ask him to jerk off for them so they can see what his orgasm is like and he soon shoots a big load for them.
