“I love that part so much!” I purred. “The way his knot pulls against my entrance as he's thrusting! Holding him inside so he can't pull away!” I shuddered with arousal, imagining just how I knew it felt as I watched it happening to my own mother instead. “You should play with your clitty, Mom,” I told her. “Brucie's way faster to cum than Daddy is—you probably won't be able to get off on the fucking alone, not unless you help yourself out. In fact...” I thought about it, then moved to act, resting my palm on her mound and using the tips of my fingers to tickle her clit. “Actually, never mind; I'll do it for you this time. You just concentrate on how good it all feels, and try to let yourself cum!”

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.

“Get back up on the counter. All fours.” I surprised myself at how bossy I could be with my teacher. Carol smiled back at me and crawled up on the island, ass in the air. She reached back and spread her tight ass for me. Her asshole pulsed a bit, nervously I guessed. I put my tongue on her taint, tasting my own semen for the first time, and slowly dragged my tongue up across her asshole.
