mouseholing 

Before hitting that ass, shaving your head except for a few strands, then bringing your bald head to her anus and trying to fit through, like a mouse desperately trying to enter a hole. Other possibles alternatives are by using your pubes to resemble whiskers and fitting your balls in her ass

My and my girl tried mouseholing last night

moleholing 

The activity of placing your nutsack inside of a gaping butthole, waiting for it to close up, then popping it out.

Man, this chick's ass is so tight. Totally moleholing this bitch.
