Dean groaned, frustrated. He let his head hang, running both hands through his short hair. He was silent for a few moments.

"I wasn't like that," he muttered.

"Mhm," Castiel replied.

He crawled next to Dean, leaning as close as possible, face nearly touching Dean's. He settled for being face to face instead of body to body.

"You weren't watching me so you could go home and get off with those images in your head, right?"

He pushed at Dean's shoulders lightly, making him sit up straight. Slowly, he clambered in to his lap, Dean's legs fitting perfectly between and under Castiel's. He ran his fingers over Dean's- unfortunately clothed- chest and shoulders before speaking again.

"It was completely innocent, watching me strip down to just boxers- and, sometimes, less than that- wasn't it?" he purred, pulling at Dean's shirt gently.

In seconds, Dean was pulling his shirt off and Castiel was trailing his hands over the bare skin. Dean was breathing shakily, surprised at how gentle Castiel seemed to be.

"Would it bother you," Dean asked, not even trying to hide the nervous tone of voice, "if I really did get off on watching you undress?"

Castiel let out a breathy laugh, shaking his head softly.

"I always figured a pretty boy like you had some sort of hidden interest. Yours, apparently, is public nudity."

This time, Dean laughed. He had started pulling at Castiel's shirt, insisting silently on it's removal. His hands stopped mid-pull at the accusation.

"You think that's why I watched you? Public nudity?" He scoffed. "I'm not pathetic. I just like piercings- and tattoos."

Castiel hummed in reply. He stared down at Dean's chest for a moment, then smirked. He pulled off his own shirt, biting down a grin when Dean's eyes widened. Dean reached out, gently tracing his finger over the tattoo on Castiel's bicep (a small bee and beehive), then the one on his chest (Enochian word for love), and finally the one on his side (Saturn surrounded by stars).

It was strangely intimate. They were both breathing shakily and staying silent otherwise. Castiel felt vulnerable for the first time in a situation like this and it was then that he knew he'd have to stay away from Dean after tonight. He knew that if he stayed around, he'd get attached and nothing good could come of that.

Dean had quit tracing Saturn's rings, which shook Castiel out of his thoughts. He refocused his eyes to see a flustered and aroused Dean. Grinning cockily, he climbed off of Dean's lap.

It was when he had his pants halfway off that he looked up again, finding that Dean was staring at him like he was crazy.

"Well, are you going to get on your knees for me or not, pretty boy?"
