Never trust your rival (Patreon)

Quinn always was extremly atheltic and one of the Top 3 Runner in Twin Hills. Her Rival (and childhood friend) AJ (Amanda Jane) was also in that Top 3 list, but never reached Quinn's success.
A few days ago AJ brought a Pulver from an internetshop which should cause an extrem grow of fat cells when it will be combined with protein. It was for people who had problems gaining weight. After the pulver arraived AJ mixed it with her protein drink and told Quinn that this drink helped her to double her energy while she trained for the next challenge.

Quinn did not think about that and drank the very tasty drink and started her next trainings session. While her body heated up it started to metabolize everything Quinn had in her system and fat cells starts to build up...first her tummy start to swell up, plumping her hard abbs to a little chubby looking Belly, next her hips and waist starts to widen. The Ass cheaks and little breasts starts to booble up...gaining more and more mass as Quinn run her labs.

As she felt the increased weight and wobbling breast flesh it was to late - gone was her athletic body and her muscles start to turn into fat withhin seconds. Her speed lowered and slowered and she realized that she was tricked by AJ - who stands in the door frame and was clapping her hands...

Quinn wasn't a rival any more...but AJ didn't realize that Quinn wasn't getting fat as she planned...she gained weigth on the right places and in a few days Quinn was one of the most popular Girls in Twin Hills.
