“Okay,” she blushed, moving to do as I'd asked, Daddy sidling tightly up behind her. It pretty much immediately turned into a three-way makeout session, instead, which was even better. Before long I stopped even trying to keep track of whose hands were where, as they both took turns playing with my titties and ass. Daddy's cock was otherwise occupied, of course, and since he seemed to be so preoccupied playing with me it meant I got to have Mom pretty much all to myself. God, her tits were incredible! So huge, and heavy, and soft! I liked my perky little firm ones too, but hers were just so different compared to mine, it was so much fun to explore and play! Daddy finally came in her, making her squeal and twitch in our arms, but when I tried to slide down the bed to clean her up she stopped me, just holding me close to cuddle instead. That was okay, too.

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.
