No sex for a week and force her to treat Erin nice and indulge him.
Tame.
I would do something that I believe the only one ASDRUBAEL VECT (Fucking Dark Eldar) would.
----
Cecille: You will rape me!? Hahahahah! I love sex!
Asdrubael Vect: Well...receive this spell. Sex will be unpleasant for you!
*Casts it.*
Cecillia: So what? I am all up to get fucked!
Asdrubael Vect: So go and do it!
*Cecillia goes, then returns with a frown.*
Cecillia: W-what did you do? It...it felt horrible this time...
Asdrubael Vect: I said to you the following words. "I will make sex unpleasant to you." I never said anything about pain, because I know pain gives you pleasure! NOW YOU CAN CRY WITH THAT STUPID WEAKLING MON'KEIGN 'HERO' OF YOURS BECAUSE I NEED TO FILL MY GLASS WITH BOTH YOUR TEARS!
*Laughs*
Asdrubael Vect: By the way? We are carrying that Erin away as well, he was crying because I forced him to kill two kids and ten men, but alas! The process to make him...more like us is arduous and long! We will see when he kills himself out of guilt.
Cecillia: WHAT IS THE POINT!? WHAT DO YOU GET MAKING US ALL SUFFER LIKE THIS!?
Asdrubael Vect: That...is my pleasure...dear...
*Cecillia's eyes widen as she stumbles back, horror filling her body whole. That was about their suffering, his pleasure was their DISPLEASURE, he would not make her feel tingly like Mars, or feel powerful and disgusted like Erin...no. He would make her feel powerless...disgusted...and horrified...and no pleasure. Only pure raw disgust and fear.*

Remember. There is a stark difference between pain and
displeasure.
