NSFW Mr Plankton headcanons
-Haejo trading his body for things. Rent, food, getting out of trouble, etc. He gets on his knees more often than he takes out a wallet
-He's unused to getting any real pleasure out of sex, usually focusing on his partner. He gives spectacular head to anyone and everyone (learned early on that people really liked when he put his mouth to use)
-People like to pull his hair, so he keeps it long-ish for convenience. He loves when his partners pet or play with his hair, but would rather die than tell them that
-Seduction is second nature to him. He knows exactly how to pose, how much skin to show off or how to artfully wear clothing that will make people want him
-When he's in a relationship and he screws up (he's a dick, let's be honest, that probably happens a lot), he makes it up to them with sex. He doesn't know how else to earn forgiveness. In these instances people are often rougher with him, because they're angry, and he just lets them even if it hurts/upsets him. He expresses gratitude the same way
-He’s so used to being the “giving” party that he doesn’t fully know what to do when he’s the one being pleasured/taken care of. (Tense muscles, bitten off moans, whimpering, unsure of what to do with his hands)
-He’s perfected the pleading doe-eyed look to get himself out of trouble/He’s really pretty when he begs
-When someone genuinely makes him feel good he gets loud and needy. However, a lot of his bedmates want something more akin to a toy or a doll than a real person, so he's learned to be unnaturally quiet and pliant and still
-He has lost all sense of shame over the years and will degrade himself if he thinks he needs to (kissing boots, rutting against feet/legs/surfaces, begging, honorifics, dehumanizing language about himself, lingerie, etc)
-He leans towards loose, flowy clothes that can be pulled or torn with little effort. Avoids anything expensive or branded because he knows it's probably going to be ripped off of him anyway
-He's starved for praise but doesn't know what to do with it when he gets it, leaving him flustered and squirming and avoiding eye contact
-He's very handsy with his partners, always touching them somehow as if to reassure himself that they're still there
-He enjoys his partner taking their pleasure from him while he's mostly or fully asleep, and then waking up filthy and used in the morning
-He loves kissing and excels at it. He can make out with someone for hours on end without getting tired of it
-He's very switchy. Sometimes he likes to hold down his partners during intimate moments, othertimes he prefers to be bound and overwhelmed so that he has no choice but to take what they give him (restrictive clothing, zip ties, rope, belts, gags, blindfolds)
-He would love to spend hours lazily tormenting his partner with sensation play or edging until they're begging for him
-Because of how snappy and sarcastic he is, he spends a lot of time gagged. Sometimes Bongsuk just gets tired of hearing him talk and gags him while they're doing mundane things in the apartment. He doesn't protest, just lets her do it. Sometimes she has him put it on himself
-He has very sensitive nipples. Bongsuk had him get nipple piercings so she could play with/torture him in more ways (He also has a tongue piercing that he shows off at any given opportunity)
