My first reaction on seeing this video was that it was really hot that she was cheating on her husband and that she was letting him watch her getting laid. The second reaction was that her husband must have a really small cock, and possibly a low sex drive, if she she is doing this guy with his small cock. You're right it isn't fair. I do happen to have a big cock and I fuck a lot of horny married chicks. I always get comments like, "you are huge, it is the biggest I have ever had and you are twice the size of my husband!". Obviously I had nothing to do with getting a big dick but I try to take advantage of having one.
This is every cuck husbands dream to have a wife like this. First time I watched my wife and her BF make love in our bed with no condom I was hooked and my sissy shecock got so hard in my panties. I get harder watching her than I do with her.
