Truly lost in the moment, Sanji nearly misses what Usopp says between gasping breaths. He smirks as he adjusts the sniper in his lap, which makes Usopp shudders and a long grudging moan escapes his already parted lips.
"What was that," he asks, as he dips his head in to lick at Usopp's collar bone giving the dark skin stretched over it a tender nip.
Usopp twitches and groans resistingly as he tries to catch his breath so he can speak again. "I said you didn't catch me earlier."
Sanji glances up at Usopp's face and he sees a heated look that Usopp's trying to give him even as the lewd nature of the situation keeps him from pulling it off. Sanji tries not to smile and instead focus his energy on pleasuring his lover. Usopp fights not to be totally swept away as Sanji changes the positions, getting out of the chair that they started this in and lying Usopp on the clothed surface of the galley's table. With the new stance, it's easier for Sanji to move. He starts rocking his hips and Usopp wants to stop fighting his natural instinct to work together with Sanji's movements, but he's still a little dejected by what happened earlier. "Why didn't you catch me?" His words turn into a moan as his body starts moving on its own. He's lost the losing battle.
Sanji kisses Usopp to give his own fogged over mind a moment to figure out what the idiot's talking about when they're already so busy with something more important. 'Didn't catch him... Hmm, auh... Um, when-when was that?... Oh, yeah,' he smirks again. 'that...' He holds the kiss for a few seconds longer, because he's not in a hurry to break it just yet. When he does, Usopp pants and reaches back up for him. Sanji's all too eager to return the affection. He loves it when Usopp gets clingy like this. It's much better than that resistant lover's act that he has whenever Sanji wants to get closer to him in public. It's moments like this when he knows that Usopp's truly comfortable with him. He nuzzles his forehead against Usopp's shoulder, smiling to himself where the sniper can't see.
"I didn't catch you earlier because I thought your armor would protect you," he says easily, still moving against Usopp's body.
"Aahhh," Usopp yelps as Sanji successfully finds the sensitive bundle of nerves inside of him. "Wha-what?" he asks dazedly. "What does that have to do with anything?"
"Everything," Sanji says feigning irritation. "You covered yourself up with that shitty armor." He takes advantage of Usopp's distracted brain to snake his hand between and caress his lover's lonesome members. Usopp mews softly, resisting making another loud noise again.
"What?" Usopp tries not to gasp this time.
Honestly, a little irked that Usopp really doesn't understand why he was mad earlier—or more fairly upset with himself that maybe he was taking it a little too far earlier—Sanji sighs. This is neither the time nor place to explain Sanji's new secret desire to get Usopp back into that suit so he can eventually take it off of him all over again. He'll just have to find out some way to take care of that later. He leans in, stealing another kiss.
"You're just too damn sexy for your own good," he mutters. Usopp smiles, starting to laugh before he cuts himself off with another moan.
