A/N: I. I wrote this.....

Kaku opened his locker only to have a small note fall out. He knelt down picking up the slip of paper, he looked around not finding anyone who looked suspicious. He unfolded the scrap, finding a message scribbled down on the page.

'Boys bathroom, beginning of third period.' S

Kaku's heart raced, thinking of what he wanted to meet for at third period. So Kaku went onto his normal day. As third period rolled around, Kaku was in science class before he went up to the teacher.

"May I be excused to the bathroom, it's an emergency." Kaku asked.

The teacher nodded handing him the pass, Kaku nodded a thank you before leaving the class and down the hall. He got to the bathroom before looking around. He went inside pushing open the door to find it empty.

"Hello?" Kaku called.

His voice only bounced around the bathroom before there was a slight creaking. Kaku turned to Sanji shutting the door and locking the door.

"Hiya toots." Sanji said flicking the bud of his cigarette into the sink.

"Wh-what did you want to meet me here for?" Kaku asked.

Sanji gave a low chuckle before stepping closer to Kaku. He backed up only to be pinned to the tile walls in the bathroom. Sanji's knee took pace between Kaku's legs and rubbing his leg on the slowly growing cock.

"I wanted to make sure people knew what was mine." Sanji breathed in his ear.

Kaku grunted at the feeling between his legs having Sanji smirk, he latched onto his neck having Kaku moan. Sanji bit down having Kaku moan and clutch onto the back of his leather coat. His hands trailed down to Kaku's pants and unbuckled his pants. Kaku tried to wiggle out of his grip but he stopped when his cock sprang loose.

"Well, well, toots. You got some length to you. Lucky for you, I got some length too." Sanji muttered.

He pushed him to the sink and tugged down his pants.

"I'll be gentle, I promise."

Kaku swallowed as uncomfortable feeling wiggled into his entrance. He grunted having Sanji shush him with kisses and soft nips to his skin.

"S-Sanji. I want it. Please." Kaku muttered.

"Just wait a bit longer toots, I haven't prepared you yet."

"I can adjust please." Kaku begged.

Sanji chuckled before unbuttoning and pulling down his pants just enough for his member to spring out. The door jingled having Sanji growl.

"Shit."

Sanji grabbed Kaku and pulled him into a stall. Kaku was on his lap while he kept his feet against the door. The door opened while Sanji's hand slipped over Kaku's mouth. Kaku's hands reached Sanji's hips before getting to his cock. But it felt like a coating was over it.

"I put it on before you got here." Sanji muttered.

Kaku shifted before lowering himself onto Sanji. They both gave soft grunts and clutching onto each other to keep balance. Once the intruder left Kaku was fully seated on Sanji. Sanji pushed him to the door pressing Kaku's cheek against the wooden door.

"See, you are a bad boy after all. You could of waited for him to leave. But. It looks like I am going to have to punish you."

Kaku swallowed before Sanji rammed himself into Kaku having him groan and clutch onto the door.

"You take my cock so prettily toots." Sanji grumbled in his ear.

Sanji kept pounding into Kaku having him moan until there was shock spread throughout his body and gave a loud moan.

"I found it." Sanji smirked.

He rammed harder into the spot until Kaku gave a wordless release on the door and Sanji chuckled pulling out.

"Awe toots, what a sweet release. Next time tell me."

He nodded when he heard zipping of pants he turned to Sanji straightening up.

"Wha-what about you?" Kaku asked.

"You can make it up to me later. We better go before class starts." Sanji said.

Kaku grabbed his collar before kissing him roughly on the lips. He pulled back fixing his shirt and pulling up his pants. Sanji peeked out finding no one out there. Kaku poked out a moment later as Sanji rested against the wall.

"Go on ahead, I'll meet you after school." Sanji said.

Kaku nodded before he left.

"I know your there." Sanji called.

The bathroom door opened having Zoro smirk walking out.

"Well, well, I didn't know the freshmen was yours."

"Yeah, he's mine. Now he's been marked." Sanji spat.

Zoro chuckled before stuffing his pockets and getting to the door.

"Looks like that mark still is on you." Zoro smirked.

Sanji slapped a hand over the scarred mark on his neck.

"The freshmen may belong to you, but. You belong to me got it shit cook?" Zoro chuckled, "I'm letting you have your freedom before I take you back."

And with that, Zoro left Sanji avoiding eye contact with the green haired man.

Explanation: Zoro and Sanji are on a break. Sanji started to date Kaku. The mark is pretty much hickies but Zoro bit Sanji causing a scar.
