Today we return to the laboratory of Doctor London River in the Institute for the Analysis of Agony, where she has two patients laid up and waiting to be put through another day of torment. Of course it is all for a good cause, it is important to know just how much pain a person can be put through before they snap, and how close they come to snapping on their way.London has her patients chained up, bent backwards almost in half with their ankles and wrists hung from the ceiling. Needles have been in their lower backs, fluid dripping in. London moves between the two, first to Abigail Dupree, then to Slave Fluffy, taking data. She pulls the chains slowly, bending their backs further and further. As she does so, she takes their pulse and pressure, quantifying just how much stress she is putting their body under. The answer is, of course, not enough.After their IVs have been removed, London moves the patients so that they're bent over a metal bar, their wrists chained and pull! ed forward, holding them in place. Then she takes a cane to their asses, seeing what kind of marks she can raise and what kind of reactions she can get. After that comes the pleasure, vibrating Abigail's pussy and then Fluffy's dick in turn, seeing what affect the good feelings have on pressure when compared to the bad.

Vacuum Therapy Machine

Release Year: 2021
Models: Valentina Bianco
Genres: bondage, metal collar, breast training machine, ball gag, nipple clamps
Video language: English

One of our resident HuCows is Valentina! She is so cute! We like to test new machines and configurations on her. Valentina is still a bit scared and very sensitive, so she makes a lot of noise when something hurts. This means we can read her very well, even when she is gagged. Today, we are testing the Vacuum Therapy Machine with some bigger cups. In case you didn't already know: pumping the udders makes the skin more supple, allowing the udders to stretch and grow. But you have to do it gradually and very often. That's why we are so busy here at HuCows. Of course, there was also time for a member favorite: nipple clamps before AND after pumping. HuCows don't like nipple clamps after pumping, but members do! Valentina hates you now. But that's ok.
