Video Description: Dr. Mercies has been recovering from an injury. But that didn't stop him from conducting the hottest and most sadistic remote anal domination session and laboratory experiment you've ever seen with Rebel. The fifth and final installment of her Filth Studies Series is due to be filmed soon, and it will involve some very extreme hot sauce play, so Rebel agreed to see just how much she could take in this interim lab session with the doctor. We don't approve of boring remote play around here, so we made sure that our own take on a webcam session was something incredible. Rebel got to a 9 on her pain scale in this scene. This falls into the "don't try this at home" category for 99% of people. (Stay tuned for the next in-person session, which will include a very special guest domme.)
