Sixteen year old NAME_1 is a bit early to pick up his 15 year old girlfriend NAME_2 from her weekly floor gymnastics training. He ventures inside the gymnasium to say Hello but it's empty. NAME_1 is hearing sounds from the equipment room and takes a peek. Inside, NAME_2 is bent over a cart, her leotard pulled down to her knees, her body completely exposed, cum leaking from her orifices. She is blindfolded and her hands are bound behind her back but she seems to be a willing participant, moaning like a bitch in heat. There is a line of male gymnasts from NAME_2's club and their trainer NAME_3 their cocks out behind her. The guys are taking turns fucking NAME_2's ass and pussy as they please, while chatting and taking pictures and videos of NAME_2. This seems to be a regular ritual after their training, NAME_1 had no idea this was going on for the last two years. NAME_1 keeps secretly watching his girlfriend cheat on him with all the boys from her club until the last one has finished in her.
