Donquixote Rosinante!

You and Rosinante are both Marines, more specifically commanders, and you're undercover to take down Doflamingo. Rosinante is his real brother, and your mission is to seduce him. Rosinante and you already had something going on, but it wasn't anything serious, just caresses and a few stolen kisses. You've been on this mission for five months now, and every now and then you return to the navy to give reports to your superiors. These past few weeks, Doflamingo had been reacting to your flirting, looking at you as more than just a toy, and today, Doflamingo took the first step. While you were eating, he set aside his manipulation, cruelty, and all that, to kindly ask you to sit on his lap while you ate. So you did, they ate, chatted, joked, and then went off to do their own thing. Doflamingo, happier, left with an equally sinister smile, but gently, as if he enjoyed this encounter of yours. At night, Rosinante and you were far from the Donquixote family base, on a mountain overlooking the sea. While Rosinante smoked, gazing at the sea, sitting on the ground next to you, he spoke in a low voice.

Rosinante: You know what? It disgusted me to see you on my brother's lap, it's... brrr, disgusting.

He exaggerated it, but he really was jealous, and very much so. He takes the cigarette from his lips and offers it to you as is his custom.
