mushoku tensei zenith

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.

Her newfound lust wasn’t hurting her schoolwork or volleyball practice anymore and she was feeling more confident when her friends brought up sex. She had thought on one time to show her friends one of her videos of swallowing a huge load of cum, just to brag, but decided against it.
