Dr. Foxi has been working on an experimental medicine that would help cure limp dick, some men have volunteered to test the new medicine despite the fact that she can't guarantee what sort of outcome will come from them taking my new experimental medicine. She only tells the men that they will never suffer from limp dick again and their cocks will transform into incredible creature like cocks! The men are all willing to give up their normal dicks to never have to suffer from not getting it up again. Dr. Foxi prepares her patients for the procedure by stripping naked out of her lab coat and jerking off their humanoid cock and fucking them until their cocks transform into a new and improved creature like rock hard appearance! Once the transformation is complete Dr. Foxi rides and fucks both of her patients, allowing them both to fill her gorgeous hairy pussy with their massive loads of cum!
