April Fools Sibling Competition

... anything, as younger brothers often do, although it never stopped her from suggesting things.

They had to cross the street, and the hot asphalt made them prance across. In the view of the ten houses, they didn't worry about being seen because everyone snuck across to Lambert's pool when the Lamberts were not home, which was often. The development's pool wasn't heated and was closed from September to May anyway.

They went up the side yard, breathing easier, protected from sight by the privacy fence of Lambert's neighbor, Mr. Atwater. He was the only person in the entire development with a privacy fence around his back and side yards all the way to the street. He was a grumpy old guy who kept to himself and wanted to be left alone. So, people left him alone.

The siblings passed the air conditioning and heating heat exchangers on the side of the house. There was this big wooden box-like thing less than two feet wide, two feet thick, and just over six feet high, jammed tight between the outside wall of the house and the heat exchanger for the air conditioning.

Diane hurried over to the pool's edge, dipped her toe in tentatively, and relaxed, sighing, "Oh, that is nice."

"Let's jump in the deep end," James said, racing down to the pool's far end.

"Ok," squealed Diane, following him, her hips undulating side to side and her tits almost coming out of her top.

This confused James. His sister never jumped into the deep end. She would always say something about not wanting to get her hair wet. He chuckled evilly.

Standing at the side of the pool, Diane said, grinning wickedly, "Ok, we go in together, on three. One, two, three!" and they both jumped in.

Sinking to the bottom, expert swimmers, they kicked up to the surface. They trod water for a bit each, looking expectantly at each other with wicked grins. First, Diane's and then James' expressions turned to wide-eyed terror.

"What the fuck," James exclaimed.

"What is happening to my suit?...(Pause)...You didn't?" Diane wailed in an explosion of ...
