Carl x Reader Sexual tension part 1

It's been five years since the world went to shit. You have been on your own for the last three of them because your family was killed by walkers.
You looked down sadly as you remember that haunting night after a few minutes of walking, with your head hung low,  you look up and see a prison in the distance about 20 yards away. You smiled at the building, as you thought about finally having a shower, a good night sleep, and maybe even something decent to eat. You picked up your pace when suddenly you tripped over what you guess is a make shift trip wire and heard the click of a gun.  
"Who are you and what do  you want?" You heard an oddly familiar voice. You turned onto your back to get a better look at your attacker.
"Carl?"  The boy slowly lowers his gun and fixes his hat.
"(Y/N)? Is it really you-u, I thought you were dead. " You were looking up at your best friend that you had also just  assumed was dead. He helped me up and blushed while rubbing the back of his neck.
"Uh sorry I thought you were a walker. " He looked at you sheepishly, "Really Carl, I come back from the dead and the first thing you say to me is, 'sorry I thought you were a walker'?" You sighed and he gave you a bear hug and your stomach grumbles loudly. "Come on (Y/N) let's get you inside." He starts to walk to the prison, you smile and follow him.

Carl had brought you to the prison, fed you, let you shower and gave you clean clothes, and now you guys were in his cell, (That you guys are gonna share for now :3),talking,  joking, and catching up. After a good 20 minutes of hanging with Carl he decided to go introduce you to everyone. You met Carol,  Daryl, Beth, her sister Maggie, Glenn, and an older man named Hershel. You caught up with Rick, and you met Carl's baby sister Judith. After words, you all ate dinner and headed for bed.

Carl's POV
God dammit why can't she see what she's doing to me, you think to yourself as you watch (Y/N) kill the walkers that are clawing at the fence. She was wearing shorts that just seem too short and a low cut tank top. Daryl says we have a lot of sexual tension . . .whatever that means. Your mind starts to wander when you hear a course of ews and look back over to see (Y/N) coverd in walker blood.
Reader's POV
You had gotten off fence duty at about midnight after one of the walkers you killed, splatted all over your face, hair, and clothes. You headed for a shower and then back to your room, (That you still share with Carl), to change. You are in your bra, underwear, and a tank top when suddenly Carl came thought your make shift bed sheet door.
"JESUS CARL CANT YOU KNOCK FIRST!" You whisper yelled, careful not to wake anyone up anyone. He quickly turns around and blushes a deep shade of red.
"S-sorry." He says quietly. You walk over to him and wrap your arms around his waist, giving him a hug from behind.
