Oops, i cant hold my cum
Well, normally i would say that isnt a problem, you are supposed to cum right? But in this case its going a little bit too quick. His dick is just inside of her when he tells her to stop. She stops because she doesnt want it to be over yet. But its already too late, he pushes her away and has no other option then to release. I guess she is a little bit angry, she just watches him cum in stead of swallowing it.
