It wasn't like I didn't know. I just didn't know what my other half was thinking or feeling. I usually could always tell what Fred was thinking or planning. He would just smile in the devilish way that sent shivers down my spine and I would know he had a prank in mind. Or his eyes would flash and he'd look at me and I'd know he had seen an opportunity to be shagged with some girl. Or he'd laugh suddenly and I'd know I'd be in for a joke later. It was as simple as that. But I had these separate feelings for him that I couldn't get rid of. Like torture. Fred would always crawl in my bed in the night and I'd wake up, my eyes wide open each time as he snuggled against me. I could feel myself harden and flushed with embarrassment every time. In his sleep, Fred would rub up against me and brush against my problem, making me climax every night by accident. I'd shudder and get up, cleaning it up quickly before he would wake up. Then I'd crawl back in and be careful to be a distance from him. Then he'd wake up the next morning.
"I'm sorry George, did I crawl in again? Bloody hell must be a sleepwalking thing. Used to sleep in the same bed as kids." Fred said, grinning guiltily each time. I would just shrug it off and give a half smile, nearly running to the bathroom with discomfort from the memory. When I would walk off he would glance at me with that bloody grin, almost as if he knew what he was doing to me.
"Fred I have to work on this potion tonight." I said angrily, hating when Professor Snape made me do this outside of class. Fred just looked up and frowned a bit.
"Jeez how the hell are we suppose to work on the prank I had in mind?" He asked before shrugging. "Later then."
I nodded miserably and began to work. Soon it was time for bed and I was too tired to go on. I quickly changed into my boxers and climbed into bed. I was rather relieved that Fred wasn't in the bed tonight. I fell asleep easily yet woke up just as easily as I felt fingers curling around my waist. I opened my eyes but kept still as I usually did, hearing Fred groan in his sleep. I tried to pull away and sat at the edge of the bed, curling my hands around my hair in pain. I couldn't stop myself from wanting to be in there with him, wanting to feel him inside of me, wanting that grin to be for me. I shuddered but let out a yelp as I was pulled back, nearly whining with frustration. Fred curled his arms around me tighter so I couldn't try to stay away, not that I wanted to exactly, and I felt the familiar feelings in my crotch. He quickly began rubbing against me, his hands on the outside of my boxers. Just the feeling of his body against me made me climax again. I shuddered and curled up for a moment before getting out of the grip and cleaning up again. I felt like a guilty little kid who wet his bed or something, the warm stickiness covering my legs and boxers.
