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.

I knew how much Daddy liked that sort of thing when he was fucking me, and I figured it was probably even more important for Mom. I got there quicker this time, I think because it just felt so naughty to be feeding Mommy Brucie's cum instead of Daddy's. I totally rubbed my pussy all over her face when I came, too—not because I was trying to this time, just because it felt so good I couldn't stop myself from bucking my hips! Daddy gave me one last kiss on my lips, then got out of my way so I could slide myself down and lay on top of her.
