Dr. Spankencock's Sexperiments

Johnny wakes up in a mad scientist's lab, with no clue how he got there or why. What he does know is that he's suddenly got a massive new dick, and it gets bigger and harder than ever. To complete her sexperiment, MILF scientist Cherie has to make sure it works. She sucks his new cock, and then he pounds her pussy until she can't walk straight.
