I have had hubby help out with another mans cock with his mouth but he was willing. What I did was have him join me in some tongue action to begin. He took it upon himself to think he was supposed to take it in his mouth. It was a pretty erotic sight and I was surprised when he did that. Of course, I'm greedy so he had to stop so i could take back over again. He has also eaten another man's cum off my leg, stomach, and breast on a few occasions. He so wants to be involved in any way he can that he would probably do whatever to be so. I have never considered nor has anyone ever offered to screw his ass. Best busy getting us drinks and things.
