Lamb dip

When a young man is invited into a cuckold situation, after he has 'dipped' his dick in the woman, the cuck sucks it clean.

"Hey, see that older couple over there?"
"The chick with the short skirt?"
"Yup, it was a lamb dip kinda night."
"No shit? That fucker sucks cock?"
"Dont judge, he deepthroats better than she does! She had him cleaning it all night!"
