[He doesn't mean for it to feel impersonal, but... well, he can't help but realize it had, once Dedue pulls him back into his lap. It's warmer, and he smiles back at him when he catches that slight smile up at him.
And here, too, Sylvain's experience serves them well. He stays relaxed, and when inexperience causes a spark of pain from time to time - as would happen with anyone, especially with someone with hands like Dedue's - he doesn't let it show. He does, however, let it show when something feels especially nice, so his friend can learn from experience.
He tries to stay upright - and he does a good job of it, for a while, staying high up on his knees so Dedue can have all the room he needs to work, to figure this out, but once he starts working a second finger into him, he can't help but groan softly and just sort of melt against his chest, draping his arms around Dedue's neck. He keeps his hips up, so there's enough of a gap between them that he can keep working, but he also makes no secret of how much he's enjoying this, either.]
