As the bedroom door closed, Roy could just picture the scene occurring. Two young women were getting heated and intimate. Perhaps they were taking their clothes off or pressing their bodies against each other. It was a fantasy that he often dreamed of. Yet, of those two girls, one was his roommate's girlfriend, and the other wasn't even really a girl?
Behind the appearance of a school cheerleader was his friend Jack's personality. Sure, she may have looked like a hot babe from school who just happened to dress like a tomboy, but it just wasn't the same. Roy suddenly felt ashamed of himself for listening in on the erotic action that was starting just feet away from him. His thoughts told him that this was wrong.
Just as the moans of horny lovers started, Roy backed away and shut his own bedroom door, silencing the proof of whatever naughty things were happening on the other side of the apartment.
Outside, Jack in the cheerleader's life was already out of sight, and probably close to school. Roy pondered about heading after him (or her?), but other things were on his mind at that point.
The device in his hand was of great power, and completely reversible by the looks of it. Jack and the cheerleader may have been swapped, but as far as they knew, it was completely normal. His roommate had always been some girl who was considered man, and the cheerleader just happened to have a guy's body. Their lives were still intact, even if their bodies didn't match them.
Roy took a deep breath and laid his eyes on the pedestrians walking the street below. There were countless subjects to test with the device, and even more endless possibilities to swap them with.
