You are a weak and submissive man and your wife knows how to take advantage of it to let off steam on you. She is having fun with you and she is right, because a weak man must be obedient with his wife. Me too, my wife knows how to take advantage of my weakness but she is not as bitch as yours.
Your wife is really bitch and sadistic with you. First she excites you and caresses your little cock and then she hits your balls. Do you like that she slaps your balls? Or does it excite her and she likes to make you suffer? Even dressed your wife has fantastic buttocks to look at. I like how she sits on your cock and rubs and shakes to excite and tease you. She's really a bitch because in the end she withdraws and leaves just when you're going to cum.
