This story takes place in high school, me and my gf were both 18. I don't like doing physical descriptions because I like keeping their ID's as secret as I can... but she was a shawty.
My ex(i'll call her mary) and I had been dating for around 6 months at this point. She was my first relationship so I experienced many of my firsts with her. First kiss, first cuddle, first you know what, but she was not the first girl to fart on me. Needless to say I was inexperienced in the relationship, but she was very comfortable around me and would text me frequently about needing to fart in class or farting in the shower after her softball games. Though she had yet to rip one in front of me, her just talking about them drove me crazy. Thankfully, my dreams would come to fruition after one of her games.
I would go to all of her softball games(both to cheer her on and because literally no one went to the games) and after we would make out in public and do all the things the high school sweethearts do. This time however we went out for food and then back to my house(my parents weren't home). We put on supernatural and cuddled up on the couch under a blanket. A few minutes into the episode, I felt a vibration on my lap. Mary was sitting on me and it felt like her phone vibrated, but she started giggling and shaking the blanket. Soon enough the smell hit me and we both started laughing uncontrollably. Apparently the food made her gassy and she had been letting them out silently the whole time we were watching the show. I took this opportunity to tickle her stomach and she let out a zipper fart right into my lap.
After a few more laughs and silent farts, she eventually went home for the night. Unfortunately, there are no other stories from Mary though we dated for a few more months.
