Your spunky girlfriend announces it is diaper night. You are not so sure about this as you watch while she puts a disposable on herself. Then it is your turn. "You will love it" she says. "I can make it sooo much fun putting a diaper on you". You are very sceptical about this but when she gets to cleaning your cock, especially pulling down your foreskin for a thorough job, you must admit the attention is rather nice. But it gets better when she rubs in powder over your cock, balls and bum. You get quite a stiffy which does not go unnoticed. Finally she tapes a disposable diaper on you and shows you how much fun it is making the crinkly noise.
