A/N: WARNING! Smut! This is what happened after they ate their pizza...
*Eren's P.O.V.*
"I'm stuffed!"
"You did eat rather quickly," Levi snorted.
"Hey! I didn't eat much today!"
"I didn't either."
"Well... Anyway... What's for dessert?"
"Hmmm... How about you?"
Levi was up in a flash. He lifted me out of my chair and brought me into his chest. I gasped at the sudden closeness. Levi's lips collided with mine. The fight for dominance started but Levi was ahead of me. Levi grasped my bottom lip in between his teeth and his tongue slithered into my mouth. Our tongues danced at their own rhythm and I was becoming light headed. Levi's grip on me tightened.
"L-Levi... Let's take this to the bedroom."
He picked me up, bridal style and glided up the stairs. He lightly kicked his door open, so he could keep his hands in my hair. We never broke our kiss unless one of us needed to breath. Breathing was becoming a hassle... We ripped our clothes off in no time as our bodies touched the bed. Levi was on top of me as he left feather-light kisses along my neck, all the way down until just before the shaft of my penis. I whimpered and squirmed. I craved his mouth's affection on that particular part of my body. My wish was granted when he suddenly licked the head.
"Mmmm... Levi."
He continued to lick the head. I ran my fingers through his hair and gently pulled. This rewarded me with Levi's full mouth. Levi bobbed his head up and down. In that moment, I swore he didn't have a gag reflex. He continued his relentless taunting on my body as I moaned my lungs out.
"L-Levi! I'm about to c-cum!" Not long after, his mouth was filled with the after math of his good works. He swallowed my fluids and smirked at me.
"Not bad brat. Now, I want to be inside you."
I blushed at his words. He stuck three fingers out at me and I immediately knew what to do. I sucked on his fingers like my life depended on it. His moans vibrated in my ears. My penis responded to this and was already starting to harden. I moaned against his fingers and he withdrew them.
"Spread your legs."
I spread my legs almost to the point it hurt. Levi, gingerly, stuck the first finger in. I moaned in pleasure. He immediately inserted the second digit and my back arched off the bed. Levi used his other hand to rub circles into my hip. It was soothing and, soon, the pain was gone. The third finger was in and I was already a hot mess. His fingers were moving, and my moans were non-stop.
"Levi! I can't take it! Just fuck me already!"
Levi removed his fingers and replaced them with himself. It was slow and assertive at first. Our needy moans were proof that it wasn't enough though. Levi's pace quickened, and my hips were there to meet his every thrust.
My hands found his hair and his hands found mine. We pulled each other into a passionate kiss and our moans vibrated into each other's mouths.
"L-Levi... I-I love you!"
"I l-love you too!"
"I'm about to cum!"
"Me too!"
"Levi!" "Eren!" We found our sweet release together and fell asleep in each other's arm.
