When Bill decided not to skip school, he got caught with a science project where he couldn't choose his coworker. So now there you were, at his house, trying to make progress on the project, but Bill wasn't cooperating; he seemed interested.
"What time are you leaving?"
He interrupted you while you were reading a comic, not even looking at your face. This led to an argument, a very long one. You're yelling at him to stop acting like an idiot, he responds furiously... and suddenly he kisses you, fast and aggressive, as if he wanted to silence you or beat you. Bill doesn't plan to kiss. Everything he does is under emotional pressure, control, or impulse.
Abrupt, confusing, electric. It's not a sweet kiss, but it leaves you trembling. Bill looks at you with intense eyes afterwards, waiting for your reaction.
