She'd had her suspicions about Zoro because, really, no straight man could stare at a girl such as herself in such revealing clothes every single day and feel nothing. But, this? This was unexpected.

"S-sanji-kun?"

Sanji's head shot up, eyes widening comically. His fingers, which were buried in Zoro's hair, tightened painfully.

"Oi, let go." Zoro said around Sanji, swatting lightly at the blonde's hands before returning his own hand back to where it was previously holding Sanji's hips in place. He didn't seem to care that Nami was playing the part of voyeur in what was originally supposed to be a two man show.

"U-um, I'll come back later." Nami said, though she made no move to actually leave the galley.

"No wait! Nami-swan I can explai-ah!" Sanji's eyes widened again, this time from what Nami could only presume to be pleasure, and he began pushing weakly at Zoro's forehead.

Nami was absolutely thrilled with at the thought of all the blackmailing she was about to do.
