Somewhere more private? That was a bit fast wasn't it? Oliver didn't worry about it for the moment, he felt... a tongue? against his lips and his tongue darted forward to greet it. He was a quick learner, and an excellent student since he paid attention. Right now Tristan was teaching him things he hadn't expected to ever want to learn.
He pulled back when his lips and tongue started to feel a bit numb. His hand was touching Tristan's cheek gently at this point, and he had no idea how it had gotten there, "maybe I can help you forget someone for the night in exchange for you helping me learn a few things," he suggested with a smirk.
