After you all finished eating, you went back to Rin's room. Rin was currently trying to finish his homework but was struggling with getting it done. You had already finished yours, so you sat down on his bed, watching Usamaro look through Rin's old stuff. You smiled softly as you remembered your conversation with Rin earlier before the mission of the phantom train.

*Flashback *

You sat down on Rin's bed, as he then joined you. You two had just had lunch a while ago. Being with Rin got you thinking...

"Rin? " You mumbled shyly. He quickly looked at you and smiled.

"Yeah? What is it? " He asked with his infamous grin. You blushed slightly at your boyfriend's cuteness.

"I was... Just wondering... " You mumbled. Rin then took your hand into his.

"What's wrong (Y/N)? " He said softly.

"Rin... If we were to... Get married-" You were cut off.

"I wanna have kids. " Rin stated firmly as he held your hand tighter. You looked over to him as you saw him blushing slightly while looking into your eyes. You smiled softly as you blushed even more.

"Then, how do you think... Our lives would be together? " You asked curiously. Rin smiled.

"Well, I would obviously have us take turns cooking, especially since you're really not that bad at it. I'd play with the kids, and watch them grow. And... I'd be loving you more and more everyday we're together. " Rin finished as he kissed you softly. You blushed profoundly after hearing Rin say that. Rin pulled away slowly as he smiled softly at you. You then kissed him back, as he then began to slowly intensify it. You felt your heart race as Rin continued. His lips began to leave yours and trailed down towards your neck, as he planted kisses everywhere. Rin then began to lick and suck on your neck, as he found your sweet spot. You moaned softly at this action. Your heart skipped a beat and you blushed even more. Rin looked up at you, his face was as red as yours. He looked into your eyes.

"(Y/N), I want to make love to you. " He said while cupping your cheeks. You blushed furiously at those words. You stayed silent, not knowing what to say. Rin took your silence as a sign that he messed up.

"Sorry, I guess I'm getting ahead of myself. " He said as he backed away. You shook your head as you caressed his cheek. You then leaned closer, making your foreheads touch.

"No, it's not that. It's just that it's my first time and I can't believe you actually want to do it with me. " You blushed. Rin kissed you as he pulled away.

"(Y/N)..." Rin muttered as he kissed you once more, he licked your bottom lip, asking for entrance. You shyly complied as his tongue wrestled with yours. You slightly moaned, as his hands traveled from your waist to your chest. Rin then began to unbutton your sweater, you blushed as you took off his jacket and tie. He smiled softly as he continued kissing you, he then went back to your neck as he left love bites on your collarbone. You moaned softly as you kept your hands on his chest. You could feel his heart racing, along with yours. You shakily began to undo his school shirt, as he did with yours. Rin brought one hand up to squeeze your breasts.

"Mmmmmhhhh... Rin!" You moaned loudly. He pulled away, his face was red as yours he kissed you passionately. Rin felt nervous as he continued, wondering how the first time would be like. He wanted it to be special, since you're the only one he ever loved this much. Both of your shirts were on the floor, you blushed as you saw Rin's well-built chest. As you continued your make out session, Rin tried to unhook your bra, yet he had a little trouble with it since it's new to him. You noticed as you giggled. Rin pouted.
