Barcus is someone who, in spite of his great fondness for dick, really does notice facial features and personality traits first in the attractive people around him. Were someone to ask, he would definitely compliment Xander's eyes, and Viktor's perfect cheekbones. Among other things.

In the meantime, even as he relaxes into the attention, he smirks a little at the way Viktor is snuggling up behind his lover. "Well, we just need to think of an idea. I certainly don't want to monopolize your time together when you're having fun, but I do fear my workbench has had enough of me for the day. Just chase me off when you want privacy again."

Or don't. He kinda likes this.

"Mmmhmm," he murmurs in answer to Viktor. "Very good with his hands." Whoa, wait, that came out wrong. His ears turn violet. "Erm!! I didn't mean for that to sound lascivious; my apologies."
