My wife swallows it most of the times.
I think she rather does it to please me...not bevause she likes it so much. When my cum is too "dense", fishy or "crumbly" she spits it out.
I have to say, that i shoot quite a lot of sperm...so its not an easy task.
Every once in a while, she agrees to let me cum on her face. But when I do, most of it shoots across anything else but her face
