I mean, she's a (half) succubus, a literal dream demon. I get not all succubi are dream related, and it seems like they just use them more for focusing in on the energy drain, or horny cum feeding aspect of them...but dreams are cool! Wrap them in sweet illusions, cloud their sleeping or waking thoughts, and make them stain their underwear till they're soaked, without even a little, itty bitty touch anywhere on their body.
I mean, you can just swap between the two, if you want. Like getting worked up in a dream, and forced to dump sperm out to any stimulation once they wake. Is it something embarrassing? Peverse? Will it deepen their addiction to Merlin? Is it some sort of...contract that's bound with the spilling of sperm? Ooor, do they just need to say "Yes. I want to cum! Make me cum! No matter what I have to do...make me cum!"
I suppose you can do things that start awake, and lead to dreamland. Once you're sleep...you can't really do anything, now can you? Your body is hers to toy with, and who knows what shape or position you'll be in when you awake? Bound? Turned to near dry fish? Did your body learn it's new master, or did this sweet(half) succubus figure out your weak points? Or...can you ever awake from her sweet dream. An eternity, or what feels like one of pleasure. Turned into a manabattery, and eventually drained dry. It could be quicker though! What if your defense against being drained, all your mental walls drop once you're out? Or a land of illusion, where the big bad half succubus was forced to leave you alone, or you somehow turned the odds on her? You won, or at least got away. You're safe, now that other girl you like is going to do all sorts of things to you! A crush giving you what you desired...Maybe just some rape, some femdom, another thing is trying to steal your cum, but since you aren't enduring Merlin, all those avenues to suck you dry are open.
Setting switching does sound fun too! Or a rapid chance of just who's raping you. Positions suddenly chagning could be a thing too. Trying to take this little waif to pound town, and just as you stick it in, or when you're gonna blow, she's giving you a reach around. What if there's 2 Merlins? 3? 10? 100? 1000? A dream is a dream, it doesn't need to make much sense. Just get drawn deeper into your own personal paradise, or whatever she deemed good enough for you.
Submit to half succubi. It will be heavenly.
