Billy Chain

An all-male sex orgy. Literally, a chain of "Billies".

Then, when I opened the door, all I could see was writing male flesh. They had a total Billy Chain going in there.

Belly Chain

To ejaculate into a woman's navel in such a manner as to cause the ejaculate to run down either side of her stomach.

Jim said he was fucking Mary and when he came he pulled out and gave her a belly chain
