Your POV 

I woke up to being on the couch and not having any pants but a blanket on me. I sat up slowly and rubbed my tired eyes. I looked around the dimly lit living room and smiled. I found my Mad Scientist on his computer desk asleep. I stood and walked over to him silently. I kissed his forehead and he groaned as he woke up. He looked at me and smiled. He turned from his desk and pulled me to his lap. "Good morning." he mumbled. I smiled and hugged him. "Goood morning." I said. He smiled and looked at me. 

His emerald green eyes were still filled with sleep. I smiled and kissed his nose again. He smiled and nuzzled into my neck. "I'm hungry." he said. I chuckled. "You can't have what you have in mind. I'm not food." I said. I felt his teeth graze my skin. I released a small moan. "I could eat you all day." he said. I whimpered and blushed. "Stop that!" I said and slapped his shoulder as he tried to leave a mark. "But I didn't get to show you how much I missed you yet!" he said. I got out of his grip to find a pouting now more awake Stein. I grabbed his hands and pulled him back over. "Be a good boy and shower." I said. He looked at me and rose a brow before releasing a small sigh and standing. I watched as he stood over me and walked slowly down the hall. 

I sighed and kicked his chair back under the desk and walked to the kitchen. I began breakfast and smiled as I heard the water shut off after a bit. I heard his footsteps echoing down the hall and he turned the corner. He smirked at me before walking over and standing behind me. He wrapped his arms around my waist and pulled me to him. I smiled and leaned into his chest. "What are you making?" he asked. I smirked. "Food" I said. He chuckled. "Smart ass." he said. He moved away and to the coffee pot. "You asked." I said and looked at him as I turned to the counter and readied our plates. 

He smiled and leaned on the counter and sipped his coffee. "I did yes, but that doesn't mean you get to be a smart ass." he said. I smirked and put the pan down. "You like my smart ass." I said. he chuckled and put his mug down. I turned to the food and jumped as I felt his hand hit my ass firmly. I squeaked and he pressed himself against me. "S-Stein! Stop that." I said. He held my hips tightly and nibbled my shoulder. "Hmmm. But I'm sooo hungry." he said. I blushed and sighed. I turned around and he picked me up and put me on the counter. 

He kissed me and wrapped my legs around his waist. I smiled and looked at him. He pulled me closer to the edge of the counter. His hands ran along my back while I played with his damp hair. He smirked and licked my bottom lip. I could start to feel his semi hardened length. I moaned lightly as he flicked his hips at me. "I want you~" he said. I smirked and bit my lip. "Then take me~" I whispered. He smirked and ripped off his shirt. I smirked and traced his stitched lines. He smirked back as he pushed me over. It didn't take long until our clothes were off. 

He began to tease me as he had my legs split to the sides. I moaned and held onto the end of the counter. He smirked as he pushed in halfway and thrusted slowly. "You've been very naughty making me wait~" he said. I moaned and tried to move closer but he held me in place. "You're being bad teasing me like that~" I moaned. He smirked and slammed in. I moaned and panted. He began to thrust a little faster than what he was but still slowly. I moaned loudly as he found my G-spot quickly. He smirked and found that spot over and over. I began to pant and squirm. He smirked as he sped up and went harder. 

I grabbed his hands and pulled him closer to me and smirked. He flicked his hips at me as he continued to thrust. I sat up slowly and he moaned. I smirked and wrapped my legs around him as I pulled him closer. His thrusts became long and slow as he held me closer. I kissed his chest and worked my way up to his neck before I reached his lips. He smirked and kissed me deeply. I smiled and returned it as I moaned into the kiss. I soon began to feel the knot get tighter and he began to get sloppy and pant. He smirked and whispered my name huskily as he was getting closer and we both knew it. I buried my nails into his shoulders as I felt the knot release. 

"Stein~" I whispered. 

"(y/n)~" he breathed. He pulled away and I grabbed the counter. We panted heavily. "Damn." he said. He cleaned himself up and the floor before picking me up and carrying me to the room. I began to get tired and watched half asleep as he put me into the bed and tucked me in. "Sleep well my baby girl." he said before he kissed my forehead and I watched him leave the room closing the metal door softly behind him. I fell into a world of darkness.
