cunnulingus

Noah punched her in the solar plexus, pushing all of the air from her lungs. She wanted to drop to her knees, but his hold on her was absolute, as though she was shackled to a dungeon wall.“The gods didn’t protect Seraph from me, so don’t expect them to protect you. Start talking before I grow bored.”

After my boner mishap, either she was getting more daring, or my imagination was running wilder. One day Mrs. B. was wearing one of her short short skirts, no stockings, just muscular shapely legs. She couldn’t help but notice me watching her move around the room. She stopped at the desk of the student in front of me and bent at the waist to look at her paper. When she slid her hands between her thighs and bent a little farther, her skirt raised exposing her panties. They were red. And lacey. I thought she gave me a sidewards glance to see if I noticed. Maybe not. It really didn’t matter, though. As soon as I glimpsed those skimpy panties, I came in my pants. Right then. In class. I’m not proud, but I was only 15, I could cum at a good card trick. I had it bad.

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.
