Your POV

I've been living with the professor and Ms. Marie for a little while now, currently Ms. Marie went shopping so that left the professor and I alone. I pushed the metal door to my room open and the hinges screeched loudly. I cringed a little and let is slam behind me as I usually did. My feet padded down the cold concrete steps to the main level of the lab. Reaching the main floor of the lab I could hear the tapping of the keyboard, this told me that Stein was on his computer. Working on tests or doing some kind of research.

Walking over to him I wrapped my arms around his neck and he leaned back letting himself relax. I smiled and kissed his cheek gently. I forgot to mention, that we're dating. No one else knows. Not even Marie. She can't know though, she would probably flip her lid and then tell everyone. Spirit would never let it go that Stein has a girlfriend. None of the students can know, they already find him creepy. Our little secret, a forbidden love of sorts.

"What are you working on?" I asked

He hummed gently. "At the moment it is research, but after that I have to work on the next lesson plan for class."

I pulled him out from under his desk and turned him to face me. I climbed onto his lap and he wrapped his slender arms around me and put his chin on my shoulder. He sighed heavily. I smiled gently and ran my nails up and down his back as he shivered gently.

"What a peculiar response." I smirked.

He sat up and shook his head as he turned his screw. "You know exactly what your touch does to me."

I shrugged "Still fun to see, I suppose."

It grew quiet before an idea hit me. I stood up and he looked at me before stretching a little. "I think you need a break from school work."

He rose a brow at me and tilted his head. "What are you thinking of?"

I shrugged. "Marie isn't home. There's a room upstairs that's empty and has a lock on the door."

He grinned as he picked up what I was laying down. He stood and picked me up in his arms as he started walking to his room as he left his computer in the dark as the spinning screw screen saver came on. I wrapped my legs and arms around him as he held me close. I felt his right arm leave my body as it grasped the metal handle for the large metal door. He pulled it open and used his foot to hold it open long enough for him to step through with the both of us.

He walked to the bed and threw me on it before he took his lab coat off and threw it to the desk that was on the other side of the room. He looked at me and smirked as I giggled gently. He grabbed my hips and pulled me to the end of the bed. The backs of my thighs met with his as he bent over. His hand was next to me on the bed and I reached up and cupped his cheek with mine. During intimate things like this he's never rough like he is with his specimens or how he is with battles.

No, he's always really gentle. He moved down slowly and our lips met. I couldn't help but smile into the kiss as he put his weight on me. It was enough for me to feel it but not enough to hurt me. He pulled away and brushed my hair from my face. He gave a small smile. One that I don't see often, well I see it more than the rest of the students at least. I wrapped my arms around his neck and my legs around his waist as I pulled him closer. I buried my face into his chest and he chuckled gently.

I kissed his cheek again as I pulled away. He sat up slowly and looked at me. He walked over to the dresser and took off his glasses before he put them on top of it. From there he moved to the door and pushed his foot against the bottom to align the locks on the door. He slid them closed and turned to look at me. I let my legs fall to the side of the bed now as my back was arched.

Grabbing my legs he lifted them and spread them before bending over and kissed me. He trailed his kisses from my lips, down my jaw line, to my neck, there they kissed small circles. He was hunting, hunting for my sweet spot. He found it as I gasped sharply. After that he nibbled lightly and licked a little making me shiver. He stopped and continued his kisses down to my chest as his hands pulled up the hem of my shirt and found their way to my stomach.

He leaned back to look at me. "You're the only human being whose skin I don't want to change to sand paper~"

I blushed gently. Most people would see this as some creepy threat, but this was how he complimented me. It means that he loves me how I am and he doesn't want to make me into how he sees the rest of his specimens.

I sat up enough for him to lift my shirt and throw it to the floor. He pushed me back down as he kissed around my breasts. I arched my back as he reached around and unclipped my bra, pulling it off of my body and throwing that somewhere else. He grabbed each of them gently. He kissed and licked one while playing with the other. I could feel my nether regions get a little warm as my breathing became heavier.

He moved from one to the other before he kissed down. He got to the hem of my shorts and lifted my legs and put them over his shoulders. I sat up and was propped on my elbows. He looked up at me for a moment before smirking. I looked away blushing and he went back to what he was focused on. I looked at him from the corner of my eye as he began kissing my core through my shorts. I bit my lip from the touch and hummed gently. His fingers curled themselves around the waistband of my shorts and tugged lightly.

I lifted my hips and he pulled them off. Throwing them and my underwear at the same time to a dark corner of the room. He grabbed my thighs and began to kiss them as I felt his breath brush my core I shivered. Eventually his lips met my core and I arched gently as his tongue went to work. My hand found his silver hair and got tangled in it. I moaned gently before I smirked and grabbed his screw and spun it. Resulting in him pulling me closer and holding me tighter.

He inserted a finger and began to rub it against the roof of my entrance. I gasped and could feel a tightness in my stomach. Another finger was pushed in and worked with the other one before I moaned loudly and gripped the sheets as I reached the end. He pulled away and stood before leaving me there a panting and twitching mess. He took off his sweater and belt and kicked them away. He unbuttoned his pants as a tent was noticeable in his boxers. He smirked and pulled them off slowly, then he went to the dresser drawer and opened a small box and grabbed a small tinfoil pack.

He opened it and slid it on and walked over to me before he pushed his member onto my clit and teased me with it. "Marie will be home soon, we'll have to be quick."

I nodded and he bent over gently before kissing me. He nibbled on my arch of my ear. "Ready, darling~?"

I grabbed his shoulders and nodded. He pushed in slowly and his breathing hitched and I moaned gently. It was my first time, but it didn't hurt as much as I thought it would. He sat up and began to move slowly. I moaned gently as he intertwined my fingers with his. He looked at me and I nodded before he started to hit me harder, I moaned a little louder and bit my lip as his breathing got a little heavier.

Letting go of my hand his hands moved to my hips and held me still as he went harder and faster. At this point I was pretty much screaming, his name. He pulled out and flipped me over on the bed, with my legs hanging off. He pushed back in from behind and grabbed my hips and my ass a little before squeezing. I gripped onto the sheets as he started his thrusts again. I could feel the familiar tightness in my stomach again as he pounded into me. He leaned forward and kissed my shoulder a little.

"I'm close~." he panted.

I bit my lip. "Me too baby~"

He was quick to finish me off. We were both breathing heavily after we were done. He stood up and look off the condom and picked me up. "We need a bath before Marie gets home." he said and all I could do was nod. My voice was just about gone, we'll have to tell Marie that i'm sick if she gets curious.

He put me in the tub before starting a bath and getting in behind me. He wrapped an arm around my waist as he lit a cigarette with the other one and pulled me close. I leaned on his chest as I played with the bubbles a little. He turned my head to look at me. He planted a small kiss and smiled. "I love you~"

I smiled wide and pulled him closer. I kissed him back and smiled. "I love you more, Stein~"

Well, this is it guys. The last part for this book. It's been fun writing this, and reading your comments. You perverted children XD. Feel free to read my other Stein Fanfics if you'd like, you know all like 15 I have of them, sometimes I wonder if I have a problem. Oh well :D. A couple have asked if I'll write a second book, but most like I won't. I have one with Spirit that I'm still trying to work on, and another with a Youtuber called Markiplier. Those need some love from Arthur-chan too! The following updates from this are going to be just me editing it, so I guess this is goodbye? Maybe? Nope, never! I'll see you guys later, maybe not on this book, but I will. Maybe in the comment section? The place that worries me the most, and tries to kill me sometimes. But anyway, I love you guys, and your comments. 

P.S I can't thank you all enough for the reads, votes and love you guys have shown for this book thus far. This is probably the most read book on my page, and that's all thanks to you guys! All 51,000 of you. I can't tell you how much it means to me to know that you guys like my writing (and my perverted mind)
