[ He only has time to breathe out a soft “oh” as Haarlep pulls him into that kiss. He’s admittedly wary, since technically, any demon/devil from Raphael’s world was a mystery that he wouldn’t dare make assumptions about… But even so. It doesn’t show.

Sebastian still has the confidence of being a powerful, brutal demon, so if he were to feel a hint of a threat, he could tear Haarlep’s head off easily. So, with that assurance in mind, he does allow it to be indulgent. He laughs into the kiss at that first slip of teeth, and he returns it in kind. It’s not so much for the pleasure of violence, though. It’s that he realizes what Haarlep is doing. He’s the clever one here, isn’t he?

Truth be told, he would handle this entirely differently if the “rules” of his Oracle hadn’t already been made obvious. He imagines that he and Haarlep could play at a cutthroat game of manipulation and conceding and taking dominance for the purpose of squeezing out as much weakness as possible, and Raphael would be none the wiser. But, the transient nature of this world being what it was…

He gasps a little as Haarlep is nudged away, and it turns into a laugh. Admittedly, it was also just unusual to find someone as skilled as he was. His attention turns then to Raphael, and he hums thoughtfully as he considers the two of them. The drawn-out note is just for show, of course. He’d already had something in mind when he brought it up. ]

Well… Greedy as you are, you certainly love to receive— [ He trails off as he reaches to lazily cup Raphael’s balls, then trail his hand up. ] —but when it comes to giving…

[ His light fingers slip from the tip of Raphael’s half (?) hard cock up to his lips. He draws his fingers across his bottom lip lightly. ]

I think you could do better. Personally.
