I had a gf who loved to cuddle falling asleep and who was an easy sleeper. She liked it when i just started f* her in the middle of her sleep and that was a big turn on for me.
On top of that, girls who want all their hol used is one my biggest kinks (also a* gap, winks and more).
If you put the element in of being super chill about it-almost ignoring me-just continue doing whatever you were doing like its the most casual thing that elevates it even more.
It's especially the 'in alignment' of me and a woman about the deep craving and dirty urge I feel to use her body; that i as a guy feel like having such a need to f or put my d in a h*** of hers to just momentarily feel relief even if that means doing it while she's just busy with some other stuff.
And then also her allowing it and thinking it is normal i feel and act this way. And the fact that underneath she actually likes it is a further turn on bc when i know a girl wants to be defiled or is kinda a nympho it rlly amps it up for me.
