At work, Derek avoided Mark as much as possible. He hadn't wanted last night to happen. It definitely wasn't the right thing to do. They were two men. Two grown men. With penises and everything. Derek smacked himself in the head. Mark's penis was the last thing he wanted to think about right then. But he just couldn't stop. The image of naked Mark kept creeping into his mind like Addison kept creeping onto Derek's nerves. Derek touched his lips with the index and middle finger of his right hand. He remembered all those kisses that Mark had put upon these very contraptions. They didn't feel any different than usual. If anything, they felt better. Healed. No. Nothing felt better, because what happened wasn't supposed to happen.
Meanwhile, Mark silently followed Derek, hoping the other man didn't notice it. He wanted whatever happened last night to happen again. He felt that it was the perfect thing to do. Sure, they were both men, with penises, but it felt right to Mark. Mark thought of Derek's penis. It was all he could seem to think about lately. The image of naked Derek was permanently stuck in his brain, but he didn't mind it at all. He actually liked it. Mark noticed that he was getting hard and leaned against a wall, trying to hide his "situation". He remembered the naked part with extraordinary detail. It had felt better than sex with Addison, and sex with nurses, and sex with anyone else. Everything was better. Everything was right.
Mark ran straight into Derek when he went to walk in the opposite direction. Derek looked up at Mark. "Move."
"No," said Mark, smirking. "Not until we talk about this."
"Talk about what? There's nothing to talk about, Mark." Derek stepped to the side, trying to walk around Mark, but Mark moved with him. Derek sighed angrily. "I'm glad we're being mature about this!"
"Me too," smirked Mark. "Now, are you going to follow me so we can talk about this in private, or do I have to pick you up and carry you?"
Derek clenched his teeth and followed Mark into an empty patient room.
"What?!" Derek yelled.
"Calm down," smiled Mark. He stepped closer to Derek. "You know you want me."
Derek laughed nervously. "No I don't."
"You so do," said Mark. He grabbed Derek by the back of his head and his back and kissed him. He felt Derek's tongue slip into his mouth. Mark wrapped his tongue around Derek's. He pulled Derek's shirt off. He then pulled his own shirt. Derek looked down at Mark's toned muscles, stroking them with the same two fingers he used to touch his lips before. His fingers stopped at Mark's waistband. He untied the scrub pants and pulled them down. Derek watched as Mark's "situation" was revealed to him. Derek pushed his own pants off, then his underwear. Mark took his underwear off too, and there it was. His penis. Just as Derek had remembered it. Derek couldn't help but touch it. His fingers glinted across it, and he was glad this was happening, whatever it was.
Mark smirked again, happy for more than one reason. He set his hands on Derek's shoulders and turned him around. Mark entered Derek and started humping. Mark came earlier than expected. He moaned as it happened, grabbing Derek's shoulder's harder. "I'm glad we're doing this. It seems like the right thing to do. We've always been us, now we're just a different kind of us. I mean--"
"Mark?"
"Yeah?"
"Stop talking."
"Okay." Mark smirked.
