Anyone with a brain could predict what happened next. Mars, trapped in the body of the person he found so incredibly attractive, but also so incredibly annoying, began to sob. He slammed the door and locked it. At least now he could be safe from Priestly's disgusting advances.
His crying looked far less disgusting than it usually did, he noticed, as he glanced in the mirror. It didn't comfort him much. He turned away from the mirror and sat down on the toilet instead, wishing Priestly was less of a complete jerk. He shuddered to think of what he was doing with his body back in there. When he got it back, he'd need to take at least three long showers. Maybe more.
The thought of Priestly having unlimited access to his body bothered him more than anything else. Unfortunately, if he tried to stop him, he'd only worsen the problem. So he was stuck, sitting inside of the bathroom, crying to himself.
It was times like these Mars wished he was more mature. He knew, deep down, that he wasn't. He was just a child. He had so much learning to do. He knew that, instead of crying his eyes out, he should get up and do something. But he didn't know what to do, and so he felt even worse about himself and just continued to sit there, actionless.
