Wasn't it stated or at least heavily implied in Mindfang's journal entries that she mind controlled the Dolorosa to give her a blowjob just to simply piss off her kismesis Dualscar? IDK, my friend said so and I don't know whether to believe her or not...

Mindfang did mind control one of Dualscars slaves into being her lover to piss him off, whether that was the Dolorosa or not remains to be seen but fanon belief is strong
