Biggs can't help but be pleased to have cut off Luke's train of thought (and there was not much left to say on the subject, anyway; they had both had their reasons). Luke's response beneath him is incredibly satisfying - No, he may not have acted with consideration for his health, but it was entirely worth it to feel Luke react from his touch. It would almost be cruel to just leave him like this, even if he would be listening to Luke by backing off now.

And indeed, Biggs rarely ever backs away from something he wants, but he can recognize this isn't the time or place; not yet. He will lean in, pressing them even closer together, and steal a kiss from Luke before sitting back up, a triumphant grin spreading across his face. "...Alright. It will be something to look forward to."
