Jesper doesn't worry about his own arousal because that will be handled soon enough. He is someone who prefers to give anyway, there are few things more erotic for him than someone spilling down his throat or coating his mouth. It's what he craves. He groans around Sylvain's cock as it pulses and pushes deeper into him and swallows it all down, lapping up afterward to be certain he got every drop of it. He manages to flick his eyes toward the mirror in time to see Claude's face spasm with his own pleasure so the both of them enjoying it at once can settle into him, deeply content.

Once Sylvain is clean he moves out from under him to behind him again, able to slide three fingers easily inside because of how relaxed an orgasm makes him. He's practically all open and accepting in this state, it's so slick and easy. He licks his lips and then steps toward the bed to dip down and slip his hands into Claude's hair, tilting his head back to dip down and steal a deep kiss out of him. With Sylvain's taste still on his tongue, spreading it into Claude's mouth.

They all have to situate a little differently to keep it moving but they're enormously adaptive, it's what makes them so good at this. "Here, Sylvain. Let me see in Claude's lap, love. You can help open me up, sweetheart. Claude, gorgeous, give a man a hand, will you?" Jesper smirks and does exactly what he says.

As they both know, Jesper is the easiest person to prep, he is automatically relaxed and very eager to get fucked, so really it's for the act of it.
