Watching another man’s cum leak out your wife is quite mesmerising. So now you have 4 choices:
A) Get down there and lick up that cum before it hits the sheets, starting with her ass.
B) Use your cock to push as much of the cum back into her cunt and simply enjoy the erotic feelings of fucking your Wife when she is already full of another man’s cum.
C) Use the other guys cum as lube and fuck your wife in the ass until you fill her with your cum.
D) All of the above.
