You could just sit back and enjoy the afterglow of your encounter with Jack or you might want to take advantage of the situation by offering yourself up to anyone else who enters the men's room. The choice is yours.
I choose to offer myself to anyone who wants to use the hole in the wall.
Jack is still inside you, but you notice him starting to get tired. With each passing moment, his hardness continues to grow more powerful until it reaches its peak at the climax of his orgasm. The feeling is intense and powerful as he shatters inside you, leaving a trail of hot seed down the inside of your thigh before finally exiting with a loud pop.
After Jack has left, you could decide to clean up the area or simply enjoy the afterglow of your passionate encounter through the hole in the wall.
