Unforgettable // Muichiro X Reader // Lemon

That's how?

Muichiro's POV:

-------

I woke up sometime later. The moon was still out but she was sleeping peacefully in my arms. She looked so peaceful and beautiful, that I couldn't stop myself from gently kissing her head and moving her long hair out of her face, only to expose her chest again. I blushed when I realized we were both still naked, having fallen asleep so quickly that we forgot to bathe. It was late, but my bathhouse should still be warm.

Gently, I stood up and threw on a robe over myself. I picked her up in my arms gently, careful not to startle her as I covered her body with a loose sheet and I took her to a bath quietly. She woke up slightly but seemed exhausted, only holding onto me, seemingly reading my mind from what we had to do before we could sleep for the night.

I made it to my private bath and tested the water with my foot. It was still warm, good. I bent down, removed her sheet, and gently placed her in the warm water where she seemed to relax more, only looking at me with a slight blush on her cheeks. How cute. I removed my robe, putting my hair up in a ponytail and joined her in the water.

"I am going to clean you alright?" I told her softly. She only nodded as she brought her hand to my face, gently tucking my hair behind my ear. Even though she was so tired, she still found a way to make me blush.

Her body was absolutely beautiful, but covered now in love bites from me. I should feel bad, but I can't help but think it makes her look even more gorgeous. I grabbed a cloth and soap and gently scrubbed her body clean while she let out a small sound of satisfaction. Does my touch alone excite her so much?

She looked comfortable even when I moved her leg into a bend to clean her more. I couldn't resist as I gave her sweet kisses up and down her arms and legs after I finished cleaning her for the night. She was more awake now as she started repeating to me the same treatment.

Her soft touch excited me again as I allowed her to clean me. She looked down through the bath water and noticed I was completely erect again. I smirked at her while resting my head on my hand.

"Sorry. Even my body finds you incredible," I told her in a teasing tone. It felt fun to see how she blushed. She was right, we could never go back, because I didn't feel uncomfortable showing her myself completely anymore. I loved that freedom.

"Muichiro~," She told me softly, causing me to blush slightly. I love the way she says my name, it's so perfect. I am glad I can't forget anything about her.

"Hmm?"

"What is that blue mark on your back?" She asked suddenly. I didn't know what she was talking about so she went behind me, tracing an outline of an apparent marking.

"I don't know. Maybe a birth mark?" I said unsure. No one has ever seen me like this before, and I have no way of seeing it for myself. How strange.

I refocused my energy to her as I turned around and gently kissed her again. Enjoying the sweet soft flavor of her lips some more before we had to rest for the night.

The morning had to come, unfortunately. Though, I did sleep in much later than normal. It seems it was already noon and she was still resting. I dressed myself and headed towards my training area only to see an angry Tengen standing before me.

"There you are! I was worried sick about you. You always get up early what gives?!" He yelled out excitedly while pointing at me. I stated at him blankly which one worsened his anger.

"I was resting with her," I calmly explained. He looked at me confused.

"Huh? I heard she made a full recovery. I came by to see you both are. Why would she need to rest this late?" He asked me. I inadvertently blushed as the gears in his perverted head finally clicked. "No way! You guys just barely had your first kiss what happened?" He asked me excitedly, making sure to usher me away from any prying ears.

"Why should I tell you anything?" I asked him coldly. He just pat my shoulder.

"Because, we are best buddies. And I have three wives so I do know a thing or a two," he explained casually. Why did I feel so embarrassed by this?

"Well, something clicked yesterday when I saw that smug doctor. He told her it was dangerous to be with me because of my memory and it led to that," I explained quietly. Tengen seemed to understand at least.

"What a nuisance. Well, at least you remembered to pull out right?" He asked me calmly. I looked up at him confused. He paused for a moment before going into a panic again. "YOU DID RIGHT?!" He yelled.

"Why would I do that? It felt right to uh-" I cut myself off. He smacked the back of my head before facepalming.

"Because that's how you get a woman pregnant. Should you seriously be doing this if you can't remember that?" He yelled at me angrily. Oh, that's how it works?! Oh no. How could I forget something like that?

I quickly left Tengen behind and ran to her. Luckily, she was awake now and sitting with Mitsuri who was giving me just as angry as a side eye as Tengen who followed me. I kicked them both off to see her with a calendar in her hands and a blushing smile.

"I should have known, I am sorry," I started to say before she laughed. I was very confused as she pointed to a calendar with strange date markings.

"Don't worry! Mitsuri showed me how to calculate when that would happen. Last night was one of my "safe days" so it's okay! I would have stopped you if it wasn't," she explained calmly. I looked at her stunned. At least she was prepared. What a stupid move I made though.

She got up as our lips met softly again only for the two idiots to barge in, yelling at me for being too reckless. Her laugh made it all the worth it as I just smiled at her.

I suddenly remembered the mark she found last night. Maybe these two would know something about it.
"Oh yeah, I have an unusual birth mark on my back. Can you take a look for me Tengen?" He looked surprised but obliged.

He examined me in a seperate room from the girls and made a shocked sound.
"Muichiro, you have a hashira mark," he said stunned. I looked at him confused. A hashira mark?
