Nightmare: It would shock him. He has no idea how to react! For once, he would just stare at you, a look of confusion on his face. Why the heck were you sitting on his lap? “Y/n, what are you doing?” he gently moves you off, his cheeks feeling hot under the goop. Good job, you embarrassed him.

Oxi: All of the eyes on Oxi’s tentacles would turn to focus on you. It is… confused? More questioning exactly why you were sitting on its lap. Were you comfortable? It does not think that it would be very comfortable to sit on… ah, no matter, whatever. It doesn’t really mind you sitting on its lap, it would just put its arms around you loosely. It is amused.

Gloom: They tense when you did that, staring at you with a big socket then they click their teeth together, “What are you doing?” they’re panicking. They’re embarrassed. Their tentacles are shifting and curling around faster than normal. You’re going to break them.

Envy: He would make a soft oh sound, before laughing. He moves his arms around your waist, leans back in his chair, and rubs your hips with his thumbs, “Well then, Y/n, how forward of you. Is there something that you need?” He found this pretty nice. He loved it whenever you sat on his lap.

Delusion: He jolts at first, and his eyes widen looking at you, blushing hard, “Y/n, what… what is this for?” His tail was wagging so fast. He’s excited but mostly confused about why you decided to just randomly come and try to sit on his lap. Was this like… for a reason or were you just doing it to do it? Ahhh!

Nightfall: He would have to pause and stare at you for a moment, then he gets a relaxed smile and he moves his arms around your waist, “Did you want a nap?” He wouldn’t mind if you wanted to take a little rest against him… he is silently panicking though and very flustered haha. 

Shade: Honestly, he would most likely be the one to sit on people's laps haha. He's very light and pretty small, so it might be better to do it like that ^^'
