I don't know what she does but every time she wants to go down on me she ends up scraping or bruising the tip of my **** like wtf, i try to tell her to slow down and go down deeper but she docent really get the point its usually OK for a while then out of know were she like hurts the head of my penis, its more pain than pleasure. In the end she apologized as i didn't get off and said that next time when were not chillin on my bros couch and at one of our places that she will rid the **** out of me, But still if a girl insist on giving you a blow job she should at least have the decency to know what the **** to do or pay attention to who shes doing it too. Sucks cause now the head has a a lil bruise on it docent really hurt, But seriously wtf
