Alec was done here, for now. He could go out into the town and explore the city as a girl, but the thought of leaving his body behind unguarded for so long didn't sit well with him. And really, what was he going to learn from that?
Now, the issue at hand was how was he going to switch back. This was going to be awkward no matter which way you looked at it. If he switched here, Amber would suddenly be in her room despite having been at his when he possessed her. But if he switched in his room she would be looking at him while he was on the floor.
Which reminded him, there was one more thing he'd like to try. Back when he was a harpy he had a clear line of sight of his body and he used that to change back, was that a requirement like with the actual possession? And from how far could he undo his possession?
Despite the risks, trying it from here seemed like the best idea.
He looked around the room and decided to close his eyes. He didn't think he could possess inanimate objects, but he'd rather not do it accidentally.
"Possession." He said.
He opened them. He was still in Amber's room in Amber's body.
He went back to his own room and stood before his closed door. He closed his eyes again.
"Possession." He said. Once again, nothing happened.
He went inside and carefully stepped over his body on the floor. He sat on the bed and stared at his silent form on the ground.
Maybe I'm not so much undoing my possession as more repossessing my own body. It did follow the logic of him having to use Amber's power to restore her body parts back. He couldn't just undo it, he had to apply a shrinking effect. He was currently possessing Amber, so he had to repossess his own body.
He considered what would be the least awkward way to repossess his own body. After weighing his options, he elected to go for a shared blackout experience. Hopefully, she would buy it. He carefully removed the pillow from under his head and opened the door to his room. He then lay down next to his own body. He quickly got up once more and cupped Amber's breasts. They felt nice.
He then laid down again looking at his own body.
"Possession." The familiar light flashed again. Alec was staring at the ceiling, his head was throbbing. He saw motion in the corner of his eye. Amber stirred.
