You are at the brink of passing gas, but you are in a place you can’t expel. So, you suck the fart back in and rip one inside yourself. Your stomach then creates the flatulent noise, but everyone just thinks you are hungry. This is the inside fart.
I was meeting my girlfriend’s parents for the first time and had to let one go, but instead I decided to inside fart.
When air gets into your penis hole while a woman is blowing your penis and it slowly leaks air, and semen, and piss
Guy 1: so how was your date with (woman’s name)? Did you get any action?
Guy 2: Yeah dinner was great and she blowed my penis till I cummed when we got back to her place.
Guy 1: Nice, was (woman’s name) any good at blowing your penis?
Guy 2: yeah (woman’s name) was pretty good until she got air in my penis hole. Then I had to penis fart.
