I found this video among the clips of the girl performing a bull-********** which someone posted in the thread below.

It is a ********** of an animal performed by a guy and a woman and filmed by a girl.
At s25 when the testicle is out of the sac and being pulled away she says that she loves that part when the ball is being torn away, the doctor replying that only a woman would say this and she starts to giggle.
At s1:26 she asks if he feels bad doing this to him and the woman replys immidiatly denying. She says that she asked the guy. He replys that he used to worry a lot about it but not anymore, and the girl giggling again.
Then they make some joke about the female doctor`s boyfriend.

There are 4 more videos of this ********** there, at the end of this one after the testicle is cut off the guy says "bye bing ben" and the girl answers with a sweet sung "congratulations" ....
