A more weird experiment

F: "OK get back into position.. Now we´ll try something very experimental, but remember that this is all part of the workout...Annie fart!" she commanded.

Annie was confused for a moment and then tensed up for a second before she let out a rather strong albeit short burst, followed by a sigh of relieve. It seemed like she had to put quite some pressure into it.

F: "Next, come hard right now!" she said quickly.

Right then and there Annie started moaning and came hard without any touch at all. Due to the surprise her knees gave in and she landed on her arms. With her legs spread and shaking, this was a great opportunity for a picture.

F: "That is interesting" she said. She realized that she even had their bodies under total control somehow. They were at her complete mercy.

F: "Elena, your turn. Fart!"

E: "Wait..." she tried to stop Franzi, but it was to late as a short and high pitched fart escaped Elena. At first it seemed disappointing, but right before her first fart subsided a second, this time very strong and long, fart followed. Elena bit her lip, squeezed her legs together and even tried to cover her ass with her hands, but it was all for nothing. Every note came out of her ass as her body intended it.
