Ya know, I was gonna say "I'm surprised he hasn't gatekeep her body", but then I realized two things:
1. He's already probably tapping dat ass so letting everyone else have the leftovers is like charity (fuck up what of saying it. I'm sorry)
2. He's already fully aware of the kind of person Niwwu is so I guess he finds it pointless to stop her, knowing that she'll do it anyways
