(Just a reminder, all characters have been aged up, so Keith is 18+ in this if he isn't already.)

You always had a crush on Keith, but being the nervous person you are, you never told him. You were afraid that he didn't feel the same way, so you never made a move.

It was a fine day in the barracks before you heard a knock on your door. You opened it up, and to you surprise, it was Keith.

"Hey, (Y/N)," He greeted you. You blushed. "O-oh, hey, come on in!" Keith walked in and sat on your bed. "Uhh, (Y/N), I wanted to tell you something." You nodded. "Well, I think... I love you. Everything about you is perfect. Your laugh, your smile, your personality, your body... Everything's just so beautiful." You blushed harder and covered your face. "I love you too, Keith."

You walked over and kissed his cheek. You sat on the bed next to him. Keith blushed and held your hand. "You really do?" Keith rubbed his thumb over your knuckles. "I always wanted to try something, (Y/N), I mean, if you're okay with it." You nodded and leaned in for a kiss, pinning him down on the bed. Keith grabbed your hips and flipped you over, now swapping places.

He pulled your pants down, revealing your pussy. He licked his lips and started to lick your clit and then took it in his mouth to suck on. You squealed. You were getting so wet. Then when you thought it couldn't get any better, he slipped two fingers into your cunt, thrusting them back and forth.

You were so wet and he knew you were ready. He pulled his fingers out, making you feel so empty. Keith pulled his own pants down, exposing his erection. He started prodding it at your entrance. "You ready?" He asked. "Yeah..." You said, your face as red as a cherry.

Keith thrusted into it and started a brutally fast pace. You squealed, a burning sensation filling up your crotch before quickly converting to pleasure. Keith leaned down and sucked on your neck, letting out warm pants onto it. His lips let go of your neck as he started groaning, his cock throbbing inside of you. Your legs started to quiver before you came.

You let out a loud shriek before Keith silenced you with a kiss. Your walls clenched around his cock, making him lose his mind. He growled and grunted before cumming inside of you, squirting his hot cum straight into your womb.

The two of you panted. Keith slipped out, and you slowly drifted off into a deep sleep.
