First, I put Ivi in a boobs-access straitjacket so she can't resist. I start to beat her in the face in long red leather gloves, with my palm and sometimes with my fist. In between, I pull her sensitive nipples. She moans and I like it. I cover her mouth with my hand, explaining that I don't like the extra noise. And I keep it until she finally understands that she needs to shut up. After I give her a few more slaps. Now she is silent. It is perfectly.
