Today only one locker was open

Today an other volley team was also doing their training, but they were doing it outside the gym. That team only had men in it, but they never trusted the members of our protagonist's team, so it was agreed, that on these days, the other team gets the men's locker and they can close it and keep the key until the end of the training, and the original team gets the women's locker. It had a door separated section with the showers, that is where the girls dressed and at the dressing section dressed the boys.

Everybody seems to be gone, except Tom. He was putting the net and other stuff away after the game, and arrives to the women's lockers as the last one. He says hello to Antonia and her best friend Diana, as they leave. The whole place seemed deserted, could it be a time to get naked in the women's lockers? That is something a guy hardly ever does...
