When I was in my teens I used to suck my own cock all the time, it never failed though I always felt bad when I came though. I wanted to swallow it so bad but after I would cum I always felt bad and would wipe it away or spit it out. This was a never ending self torture because I would purposely not cum for a week or more just so I would have a larger load because I wanted it. All I wound up with was huge stains on my shirts and a moustache full of dried cum feeling guilty, horny and bad. I would love to be able to do it again though now. I loved having my cock in my mouth.
