gengetsu hōzuki

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.

It was worse than she expected, from her pained hiss as it happened, but it was over in only a moment. Plus, I knew just how to make it better! I helped her to her feet and back onto the bed, laying her down and getting between her thighs. God, there was a lot of it!

Daddy wasn't ready to go again yet, so he laid down beside us, he and Mom passionately making out, while he ran his fingers into my hair at the back of my head and held me tightly down into her pussy. God, I loved that! I was happily doing it anyways, but the idea of him making me do it was just so, so hot! She pushed me gently away after the first time I made her cum, so I crawled up and collapsed on her opposite side, snuggling close.

“Ummm...” she hemmed, swallowing nervously. “Playtime, Brucie! Playtime!” Bruce paused in his attempts to rape me, settling back down to four paws and tilting his head in adorable confusion, making me laugh. “Playtime, Brucie!” she repeated. “Playtime with Mommy!”
