Friends... Or more?

Smut tiiiiime!!! I'm gonna try doing this from Levi's POV.

Eren had put Alice to sleep about a half-hour ago and the house has been silent since beside a random movie playing on the TV. I stroke my finger through Eren's hair gently as he lays his head in my lap. Slowly I trail my fingers down his scalp and run my fingernails along the nape of his neck. He shudders slightly as tilts his head downward so I have more room to continue. I massage his shoulders and back for a moments before pressing my thumbs into his hips and dipping my fingers into his sweatpants. Eren bites his lip to keep silent as I palm the front of his boxers and grope his ass. I pull both his sweatpants and boxers down all at once and he hisses quietly as the cool air hits his hard on. Eren's back arches and he bites the side of his hand to muffle noise as I begin to stroke him. His pupils are blow wide and his cheeks flushed pink as I pick up my slow pace and eventually I'm going hard and fast, hand hitting his hips and arm starting to burn from having to bend it at such an awkward angle. Eren begins twitching and shaking, small whines and breathy moans escaping his lips, swollen from his biting. Finally he tenses up and comes hard onto my hand. All of his muscles relax and within seconds he is asleep. "Damn..." I said quietly as I looked down and realized I never got off. "You are so repaying me" I muttered as I turned off the TV and layer down with Eren.
