A stranger barges in on Michael.

Michael lost track of time sitting alone in that hot tub. He spent most of it with his eyes closed and his mouth slightly open, beating away at his meat from below the bubbles of the hot water. His mental fantasy had escalated to the point that he could see both Lily and Cassandra stripped naked in the tub with him, Cassandra's hands planted on each of Lily's cheeks as she spread them apart to suck on Lily's clit from behind. Michael, of course, was busy pounding the buxom blonde from behind in this vision-- it was one of the best fantasies he had ever come up with, and all on his own!

That fantasy so distracted him that he didn't notice the sound of anyone moving around outside. The bubbling of the pool was loud enough, too, to mask most of the noise, only making the situation worse. Plus, he had his eyes closed, and he was entirely removed from the world.

The person outside didn't notice Michael Murphy, either. As thin as the walls in the spa were, they were enough to cover up the bubbling through the door, and the hallway had the same sort of lighting as all the hot tub rooms. There wasn't anything that could have clued them into Michael's presence, unless they were paying very, very close attention.

The door slammed open, jolting Michael out of his trance and forcing him to look into the eyes of the person who had intruded upon him.
