The bubble that forms around the top of a cup after a guy has ejaculated his semen into the cup and then put the cup into the microwave for a minute or so. The guy usually then takes the cup out of the microwave and pops the bubble with his erect penis which causes a blast of warm air to be shot into his genital region.
After having sex with the snowman I made, I decided to make a hot cum balloon with some semen I had stored in the fridge so I could pop the bubble with my erect penis and thaw out my frosty shaft.
