Sanji was flustered and covered in kiss marks, he'd swoon every time your lips touched his face or neck. Yet every time you’d sigh and wipe off yet another lip product. You had decided that if Luffy was going to drag yall around to do dangerous crap you might as well look good doing it. So you'd bought a bunch of 'kiss proof' lip products at the last island market the crew had visited . Sanji had immediately volunteered to let you kiss him to test the products, because 'boyfriend duties' or smth. Hour after hour passed, none of your products worked as advertised. "Ugh! You're probably getting bored right now" you said, wiping off your lipstick. Sanji let out a high pitched giggle, "NooOoOO!" He cooed, "this is peRFEct" his voice cracking. He cooed, his eyes practically hearts as he looked at you.
