Professor Farnsworth could not be happier! He just invented a new sex pill that actually works with him, and now he has the erection of an 18 year old! He rushes to Leela to show her his boner, and finds out that she is interested in experimenting in order to see if the effects are as good as they seem! She has always been curious about having sex with the old man, but since his dick was limp, she never thought it could happen! He is so old, he must have years of experience fucking girls from every single alien race known to men!..
