"ritual sex + penance" well. I don't think he'd like that but someone's probably going to do it for him anyway

...Frater Mathieu......

Or 30k era AU with Lorgar. ... brb I think I have to write that idea down

(the Mathieu one too tbh)

exhibitionism + body worship
non-penetrative sex + cuddling

givemedragons: The first one would have to be a coerced situation, like a Rubi festival or ritual thing. Rob can perform while being watched (he doesn't care that much about other people, lol) but it's not a kink of his. Body worship of his partner would make a lot more pleasant, though! Give him something to focus on.

Do not body worship him. No worship plz.

And non-penetrative sex and cuddling is just his regular jam. <3

Vax is into it
