So, we know for a fact that Mercer can turn himself invisible. The version of this power that's available to us is limited in time; but let's assume he managed to somehow unlock a much more long lasting version of it? I don't care how, let's just... assume.

Let's also assume he's been lusting after the newest recruit. He doesn't know whether she'd accept him or not, and he doesn't care either. I want to see him sneak into her bed and ravish her while he's invisible and she's ambivalent about what's happening.

The big kink here is invisibility. I'd prefer dubcon over noncon, her enjoying it is part of the appeal to me. Bonus if you have it happen in a public location (such as the cistern) where they both have to keep very silent in fear someone might investigate. Double bonus if f!DB ends up suspecting Mercer but doesn't have enough proof to do anything about it. I'd prefer a breton, but imperial, redguard, bosmer or dunmer DB would be fine too. Please no scat or straight up mutilation/death, but, apart from that, the kinkier, dirtier, more depraved it is... the more I will love you!

Woah, long prompt is long, sorry. Hope someone picks this up!
