Say that it was a mistake

You quickly break from the kiss, "Sorry, I didn't mean to do that." Agatha shoots you a puzzled look.

"Oh, don't worry about it." she says as she tries to downplay the awkward situation. "You should drop me back at my apartment." she says. "Yeah, right." you respond back.

After dropping her back, you reach home. You sit in your couch replaying the events from earlier that afternoon, "What the fuck happened there? Why did I stop?" No one knows the answer to that question other than you.
