Daves mates have played a prank on him for his stag do. They chained him to a wall and left his cock sticking out of the skin suit they made him wear! Sadly for Dave, three girls are the first ones to find him and rather than untying him they decide to take selfies with his exposed penis! They then take turns to stroke his cock until he is rock hard. They offer to release him if he cums but when he shoots his load they walk off laughing, leaving him for the next lot of girls!

Dr Satine has discovered a phenomenon she has called "natural viagra" - a condition where males are fully erect without any stimulation. She is presenting a seminar on it and demonstrates in front of her female colleagues by stripping a male subject naked. When he drops his pants the women are shocked at how erect he is! They prod at his cock and grasp how hard he is, but wonder if it works properly. The three of them then give him a blowjob until he cums on Eve's cleavage!
