“Oh, take it you little whore!” she squealed, her hips jerking powerfully against my ass, the hot, molten flood of her seed making me gasp as I felt it shooting deeply up my ass! “Take it! Take my fucking cum!” Wave after wave she gave it to me, her huge, amazing cock pulsing and throbbing in time with the unbelievable pounding of her hips. Then suddenly she stopped, almost as if somebody had thrown her switch, buried to the hilt but completely immobile. She stayed there for a long, slow moment, eyes closed in rapture, barely even twitching but utterly lost to the ecstasy of her release. She pulled out slowly, leaving me strangely empty and wanting, supporting herself with her hand on my stomach as she tottered unsteadily around to my side in her heels. She bent low over top of me, her huge, amazing tits pressing warm and heavy against my 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.
