Something at the gym distracts you

As you begin to head towards the door of the sports center, a sign next to a room you had not noticed before catches your eye. The sign reads: "Sexual Tipping Class". Immediately intrigued, you pivot and make a beeline for the door. When you glance through the door's window, you can see a class is currently happening.

Machines resembling a combination of exercise equipment and fucking machines are placed in batches around the room. From the look of it, each section is specialized for a specific for of tipping. The participating girls are all naked, like the yoga class, but these exercises are more lewd in nature.

While the girls perform their "workouts", instructors are pacing around and encouraging the girls by flogging their exposed skin. The room has a bit of soundproofing, but you can still hear the whirl of the machines, the lash of the whips, and the degrading insults the instructors are using to further motivate their students.

You concentrate on a few of the machines to understand how they work. One girl is performing pull-ups with a mounted bar. At the top of every pull-up, she has to deepthroat a dildo that is facing downwards from the bar. On the drop back down, the throat dildo is extracted, but another dildo buries itself in her pussy.

Another machine has a girl squatting down onto a sizable butt-plug while also balancing some heavy weights. It takes a lot of leg strength to prevent her from impaling herself too quickly on the plug.

After realizing you don't have much time to eat anymore, you quickly set off, making a mental note to return to view the class at a later time.
