These horny volunteers didn't know what to expect... but now they do and are sore for doing so! The doctor is at it again and this time, with the help of his Lusty Nurse and some horny volunteer's he has created yet another magic sauce that makes you not only Bigger but ready to do the filthiest things ever! With just one application, your cock grows to the bursting point and you had better be ready to play that thing into any hole that's nearby! His nurse finds out the hard way as does the doctor during their first trial runs, but after nearly killing the both of them, the next trial goes a little better! If that's not enough, he has yet another invention that even the CIA helped developed!
