As all nine of the men surrounded her, their large and rock hard cocks were showing off their eagerness for what was to come.
The men here had endured a lot in order to not start rubbing their cocks all over Weiss's super sexy body. But now, they were finally going to do exactly that.
So far during the session, Weiss had continuously controlled the lust and pleasure and the men and made it to go up or down according to her wish. At the same time, she had also managed to make sure that none of them would reach their climax before she was done with the experiments.
The result of this had been quite satisfactory. The lust and pleasure control abilities of Weiss had became way more precise after this round of experiments.
