I think he'd definitely leave little marks after his kisses

Similar to the marks from an octopus latching it's tentacles on you

He goes on for a big kiss and now you have a big mark on your face

It's worse when it's on the lips though...

You look straight out of the Kylie Jenner lip challenge circa 2015

He probably bites a little when he kisses you tbh

It's kinda unavoidable since his teeth are very sharp and obvious

The little baby dadadoos/naughty ones probably don't like the idea of you being with their dad and will try to bite you

But it's ok they warm up eventually!

Sir Dadadoo probably had to get pissy at them for almost killing you though

If you ever got a cut or other type of bleeding wound, he'd probably be glued to you

Either to make you feel better or to lick the blood

When he first saw you he probably just thought "another threat to my plans" but when he really got a look at you, he was like "a romantically appealing threat to my plans"

Toxic doomed couple /j

The relationship definitely started off rocky cuz of the lore in the game but he softened up a bit eventually and then was like "huh, is this love? Maybe I'll act on it."

You probably thought he was gonna kill you when he started scooting closer and closer but then he just kinda, looked at you funny

"Hello? Do you need something? Are you trying to kill me in some weird telepathic way?"

"No, I just don't know what to say to you"

"...Ok then"

Then he pulls out a drawing of a flower

They don't have real ones down there I think

It's endearing but also confusing a bit cuz you don't know what he means????

Then he just grabs your hand and you think he's gonna eat you and swallow you whole but he just leans in and leans a big kiss mark on it

"Oh"

"Is something wrong?"

"No just, didn't expect whatever that was..."

"It was a kiss, a sign of affection"

Awkward silence for a bit cuz nether of you know what to say

Then you speak up like

"So, why did you do that?"

"Kisses are signs of affection for those you love, right?"

I like to think he would like the mating press position

He also loves breeding kink related stuff, I mean, he literally got Matpat pregnant...

They go hand in hand, he loves stuffing and filling his partner while in the mating press

I also like to think maybe he would like period sex if his partner's afab because of the blood

Also because he could fill them as much as he wants without any consequences

Sado-masochist definitely

Possibly into hair pulling but not super sure

Maybe very into semi-public sex (like in the saferoom of Freddy's or in a bathroom stall.)
