chubbing

Mrs. B. was definitely given to buyer’s remorse. Each time she had sex with me, she would act really distant and embarrassed for awhile, trying to pretend nothing had happened, and trying to avoid being around me. I managed once to be alone in the room with her and I came up behind her and lifted her dress and squeezed her ass. She looked at me with a sad smile (and checked out the bulge in my pants),

“There we go! I knew you'd remember!” She grinned wickedly, releasing my dick and using both hands to fiddle at the side of her skirt. It fell away, revealing an unbelievable, thick eight inch cock, springing ready and eager into the air! God damn! I'd never have guessed Ray, of all people, had a dick like that! If I'd known, maybe we wouldn't have picked on him so much. “All senior year, you and your jock friends thinking you were such hot stuff! Pinning me down, making me suck you off, calling me your sissy faggot bitch, just because I was a little bit effeminate, and wasn't into sports! Taking pictures of me doing it, blackmailing me, so you didn't even have to hold me down anymore! Making me come whenever you'd call! You have no idea how long I've been dreaming about this moment! But we're going to see who's the bitch now, aren't we Brian? Oh, yeah! We're going to see!”

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.
