"Dave, would you like to pull out now that you are done?"
"No thanks, I am very cumfortable, your vagina is very cumfy therefore I will stay in for a little bit longer if you do not mind".

You are cumfortable when you are home alone and light some candles. Then sit down on a couch with your fireplace on and start wanking to a porn with a good plot.

When you leave your ejaculate on your (or your girl's) stomach and pass out.

On the coldest and loneliest of evenings, use your cumforter as an added layer of insulation.
Bro 1: Dude, last night I was so tired after tugging it I passed right out and left myself a bell full of mess.

Bro 2: At least the cumforter kept you warm.

Bro 1: Yea, but it was a bitch cleaning the fuzzies off my stomach this morning.
