“Everything alright, kiddo?” her dad asked softly, walking over and putting a comforting hand on her back.Sarah made a panicked noise, which she managed to turn into a tired groan. “Mmrrr… I didn’t sleep well last night.”

I started gently rolling my hips, proving my words. She was still stubbornly refusing, mouth tightly closed as I painted her face with my cream. But as Daddy snuggled up behind me and started playing with my titties again, staring encouragingly down into her eyes over my shoulder, she finally started playing ball. She was still tentative, just a tiny, testing little lick of her tongue darting out between her lips, but I rewarded her with a happy little moan and stopped grinding myself on her face. The tongue came out again, and again, and the more I responded to her the more confident she became. I still wasn't ready to let her out of her restraints yet, even once she started eating me for real, but I was definitely enjoying myself, clenching my muscles to try to squeeze out as much of Daddy's cum as I could. That was the one and only problem with Daddy having such a big cock; he always deposited it way far up in there, and trying to get it out again was just about impossible before it was ready to leak out on its own! Still I was doing what I could, and Mommy seemed like she had finally gotten out of her own way enough that she was able to enjoy the taste. She wasn't half bad at it, either. Not as good as Daddy was, judging from the few times he'd chosen to use his mouth on me rather than his cock. But still, not bad, and I was gradually drawing closer to the edge. It hit me more gently than the ones Daddy had given me, but it was no less enjoyable, making me gasp and twitch as I relaxed back against his chest.

idk if you've played chaos;head (or watched it, I never saw it so idk if it's in the anime) but it's set in the same world as steins;gate (which I've watched but never played) and things the eyes see but the brain doesn't process are a literal plot point, you could almost certainly make a fairly lore accurate manip with that if you like this world.
