Kyu

his tdick? big. he had segments do his bottom surgery, full on metoidoplasty*, combined with his own testosterone, it's big enough to actually slide in. about 2 inches in general.

he has top surgery scars that are actually quite elegant. he was meticulous in ensuring that they'd be up to his standards, and they scarred over nicely. they healed in a pattern not dissimilar to the patterns on his final form, like circuitry. his chest isn't sensitive, but if you like nipple play, he'll let you suck or bite them if you ask. maybe.

isnt opposed to vaginal sex but you either have to be willing to switch after or be fucked by another segment while he rides. he likes control, he likes observing, even if you play with his tdick he'll be keeping one hand on your neck and the other on a nipple to keep you sensitive

on the contrary, if he's the one doing the fucking? good luck. he does have a collection of straps he's made and infused with different elements for different purposes. cryo and pyro for temperature play, dendro for heightened sensitivity, hydro for self-lubricating or a strap that can cum... the smallest he's made was six inches. the biggest is... well....

huge fan of scissoring. he likes generally being in control, and grinding is one guaranteed way to have him grunting in your ear about how wet you get (hypocrite).

he will tie you to an examination table, he will put you in harnesses and gag you. big fan of pretending to dissect you as foreplay; he'll drag scalpels across and down your torso, keep your heartrate visualized on a monitor so he can note when your blood pressure spikes. he likes seeing blood ooze from fresh clean cuts the same way he likes

some of his favorite forms of bondage tend to be restraint and gagging. his favorite gag is one that fills your mouth to where it almost hits the back of your throat, because he watches how the muscles flex around it and notes when you can finally 'upgrade' to a bigger size. he's very keen on informing you how the muscles of the throat can be trained. especially when he has a strap on, to facefuck you and to note when you gag or struggle.

facegrinding and head under his desk are go-tos. if he has paperwork to fill out, he'll have you sat between his thighs, mouth warming his tdick. sometimes he'll give you a dildo to sit on, sometimes he hits the back of your head if you try to give him head proper. you're warming him, and he's not afraid to remind you of your place. if he's frustrated, he'll keep your face pressed against his crotch while he uses your mouth like you're a toy- otherwise be patient and you will be rewarded properly.

his lab is cold, so whenever he does these medical roleplays with you, your skin is crawling with goosebumps and you're shivering until he starts. his tools are cold and pristine; he had them custom made with his initials on them, and he makes sure that your eye catches the engravings every time he uses them on you. "only the best for my favorite lab rat," is what he always tells you.

lab rat, test subject, and specimen are his favored pet-names for you. he's not really one for titles during sex, but if you called him doctor and asked 'for a checkup' it's the guaranteed way to get his attention. because he knows you have to be needy for it at that point, to ask so nicely.

now his etiquette isn't great. he'll listen to safe words but in more of an "ugh what happened" way because its pausing the observation of sex, he cleans up and performs 'aftercare' but its like the aftermath of a surgery rather than sex. don't expect cuddles unless he's in a very, very good mood, because otherwise he will clean you up and then leave.
