As far as Anatoly was concerned, he wasn't going to be flirting with Clara. No offense to her at all, he liked her, just not in a way where he'd flirt with her. It was difficult enough for him to flirt with Svetlana because he tended to put his foot in his mouth more often than not when it came to her. He really was a hopeless person sometimes. At least if his parents were going to get uppity with him for not having a girlfriend, he could come back at them by saying he was a doctor and he was busy.
It was a good and legitimate reason, really. Though it also was easier to tell them that than the fact he was awkward around women he liked. Like Svetlana.
Now when she made the biting comment, he blinked a bit, looking at her like a deer in headlights for a moment. Alright, he wouldn't be asking her to bite him, so maybe he could just get the shirt off and quickly get one to replace it and then feel less awkward.
...alright he wouldn't feel less awkward but he'd feel better having a shirt on.
"Alright," he said, again just giving in because it was probably just easier to do at the moment. So he pulled his shirt off and set it in the hand she held out. And, well, Anatoly was easy on the eyes without a shirt on. Lean and somewhat lanky as to be expected with his body type, but it wasn't bad to look at.
