I like this kind of sharing where both men get involved, even if it includes intimate touching. I enjoy helping the other guy get off and I really enjoy fucking my wife's pussy with another man's load lubing her up.
It looked like during the DP the husband got her ass while the friend kept her pussy. I'm the only guy ever in my wife's ass. If we ever have a threesome with one of her lovers I think id want him in her ass.
