If out makes him feel good or works him up why not
It. Not out
This belongs in the "Confessions" section...
Doubt he's complaining
Girls do it all the time, you just got to watch this time. Sure
Whoa. That was hot. Thanks for the entertainment. I always found guys more attractive than girls. Always. Their body is just more... alluring. Is it only me? It makes me just want to... yahhhh. Anyways,the girlfriend just couldn't resist. And guys are really sensitive and it looks that way since they do get boners and we can physically see their *****. But, in girls, we can't see "it". They just get wet and ****. Not that fun. But yeah, its okay for a girl to do that, since the guy didn't get incredibly mad and walk off. He likes that sensation so its okay. hehe.
That was.. uh.. nice and desc<x>riptive. Look, if the two of them are enjoying it, why not? Not really any of your business, or anybody's business.
