Well, if you put peanutbutter on your balls on have your dog lick it off, does that constitute as cheating? Answer: No, cause its your dog.
Dude, a lot of guys in here need to step away from the computer and meet some women. No way am I sucking my own dick when I can have the gf do it. Masturbate, yes, cause no one beats the master. Blow job, no, cause I'm not geigh
Just get some heated KY and rub that bitch out. If you need help that bad, my friend got a pocket pussy, or in your case, one that is made to looklike a mouth. Better then doing it yourself.
