Forced orgasms

I found this interesting, because it's proof that orgasms can be forced on somebody who does not want it, even if they fight you actively and physically. 

At about 12 minutes in, it happens, she has three of them. Clearly real, and the brunette talks around 34 minutes in about that she was crying because she did not want it  to happen. 

Of course she was voluntarily in a competition about that, but it means it can happen also non-consensually.
