anabanana

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.

Carol hiked herself up on one ass cheek and rubbed an oily finger around her anus, depositing a bit of oil in her anal canal. She hopped off the island, grabbed my hand and the olive oil and headed for the living room. “It will be more comfortable in here. My knees are sore.” She set the oil on the coffee table and kissed me again, stroking my dick vigorously as she did. “We don’t have to do this. You can say no.”

“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!”
