Walden was not going to survive this get together. One of the guys was telling a great golf story and all he could think about was that Alan was wearing his shirt. They unwisely started fooling around before they're guests came, thinking they had enough time for a quickie. They were rudely interrupted by knocking and rushed to get dressed.
The shirt was a bit too big on him of course but he did that tucking in thing he does all his shirts so it wasn't too noticeable. But he knew and it was tapping into a possessive side he never knew he had.
"Hey man, were listening?"
"Oh," Walden said coming out of this stupor. "Yeah, yeah cool story."
He pulled awkwardly at the under arms of his own shirt, they're uncomfortably tight for some reason. He was wearing it unbuttoned over a t-shirt as he usually did so he didn't understand the problem.
The party mostly passed without incident; people did have repeat things for him, though. As they said goodbye to the last guest Walden wasted no time pouncing on him.
"What brought this on?" Alan asked after his mouth was free. "Not that I'm complaining."
"You're wearing my shirt." Walden replied with frustrated groan. "Also, why are you talking? We could be upstairs and I could taking it off of you and- and why the hell is this shirt so damned tight!?"
Alan gave him an odd look.
"You do realize that you're also wearing my shirt?"
