Wanna come over? (Atsushi x Akutagawa- fanfic) 18+ smut/lemon

The fantasy

We had arrived at his door when he began fumbling around for his keys inside his pockets.
The entire walk here was silent and the tension had only seemed to increase between us; he pulled out a single silver key and inserted it into the keyhole and at the sound of a click, the door slowly opened. As we both  hurried inside to escape the cold air that surrounded us outside, we breathed a sigh of pleasure as the warmth of his home seemed to envelop us. I took off my coat and sat by the  fire place, as it lit up and the crackling of the fire became the only sound filling this otherwise silent apartment. I sat still and silent unsure of what I was to do to break the tension in the room but before I could say a word he asked, " Want to take a shower? You can borrow my clothes."
I rose my head to look at him curiously before speaking," Are you sure, you're being awfully nice?"
He looked me up and down amused before speaking again," I simply believe I'm starting to see you in a new light Atsushi Nakajima." I stared  mouth open unable to respond at the sudden confrontation.
"What's that supposed to mean?" I blurted out. 
He chuckled," Even I'm not fully sure, but i hope to find out soon."
I couldn't help but blush as he chuckled, realising my face was burning up I stood up abruptly before saying that a shower sounded great. I walked into the room near his and slammed the door behind me before grasping the edge of the sink to steady myself. I looked into the mirror as I stared at my own flushed face feeling deeper embarrassment as reality dawned on me...
Did I have feelings for Akutagawa?!

### Akutagawa's POV

As I heard the slam of the bathroom door and the automatic fan whirring from inside, I couldn't help but smile to myself. As the image of Atsushi's flustered, clueless expression began to fill my mind I thought about how cute he was, just to realise that he also believed I hated him, ugh how am I going to clear that up I thought to myself . Just then as I mentally argued with the many ways to confess to him about the whole me not hating him thing, I heard the water from the shower as it began pour out. Before I could stop myself my mind began to wonder....
I imagined his thin, slender body and his creamy white complexion as the water splashed on his bare skin. I imagined every curve and crease of his body as the water ran down him. I imagined his nipples flushed and his smooth skin reddening from the heat: I imagined his slender waist and his long thin legs and his beautifully defined arms. I imagined my hands delicately running over his body as I felt his smooth, supple skin under my fingertips I imagined his expressions as he trembled under my touch from pleasure his eyes yearning for more and I imagined him begging for me to go further.

The small voice that came from my bathroom brought me back to reality as realisation made my face burn a deep crimson as a wave of guilt and embarrassment flooded over me as I recalled my perverse thoughts.
Atsushi called out again," Akutagawa, can I borrow some of your clothes mine aren't exactly the most comfortable."
I stuttered as my fantasy replayed in my mind, "O-oh uh sure I-I'll bring something over right away." I grabbed a pair of black Pyjamas from my closet. As I came out and faced the bathroom door, I breathed out calming myself before knocking on the door. He seemed to take a moment before slightly opening the bathroom door, looking up at me almost as if he looked at a predator about to jump on his prey, I stifled a laugh before looking down at him and trying to smile comfortingly, I showed him the clothes and he opened the door a crack wider, as he did I got a peek  of his chest as it moved rhythmically up and down his light pink nipples peeking through the corner of the door. As my fantasy began to resurface I quickly gave Atsushi the pyjamas before quickly turning around and going into a living room area on the other side of the apartment, opposite the bathroom as I felt my face burn up.
