A Hot Air Balloon is a sexual act involving two partners. One partner, the "balloon", prepares for the act a day before by eating foods that contain high concentrations of fiber and dairy. For best results, the balloon should avoid defecation until the next day when the Hot Air Balloon is to be performed. When both partners are ready for the Hot Air Balloon, the balloon positions his/her anus directly above the other partner, or the "ballooner". The ballooner opens his/her mouth to take a full load of feces from the balloon. Without swallowing or spilling any of the (most likely very liquid) feces, the ballooner must then blow up the balloon. That is to say, he/she must blow the hot liquidy feces back into the balloon's ass.

When you're going down on a girl and she farts in your mouth. But she farts so hard it fills up your cheeks with hot air.

When a woman or man places her or his rectum against a woman’s vsgina and passes gas into the vagina.

Its like when you're making love... with your special lady friend and you stretch your bean bag over her cornhole and tell her to fart.

The act of farting in ones mouth

A sexual act that is executed as follows:
The male inserts his foreskin into a receiving individual's anus or vagina and asks said receiving individual to either fart or queef, respectively, thus filling the area between the foreskin and glans penis with warm gas. The male then exits the orifice, swiftly pinching his penis as to trap the air. There must be enough air as to obviously distend the foreskin for this maneuvar to be considered a success.

The odor of a fart, released at a lower elevation, is breathed in by another person at a higher elevation. The warm methane emitted from your anus rises, thus creating a similar effect as a hot air balloon.
