I put my arms up over my head, tilting my head back and looking around as if someone might be there to overhear this crazy conversation-someone I might share my astonishment with.

“You think about it.” Her hand lightly stroked my side. I felt that gentle throbbing between my thighs, more insistent now.

“Okay,” was all I could say.

There was someone on the balcony, high above us. It was Mr. Baumgartner-Doc-sitting outside on one of the white deck chairs. He was completely naked. When I got over that shock, I noticed his hand moving up and down between his legs-very fast.

Was he? Is he?

Mr. B’s hand was warm against my side, just resting there. It made my breasts tingle, and I flushed when I realized I wanted her to touch them-to touch me. I wanted to close my eyes and my mind against the thought, but the blur of motion above drew my attention again. I knew I shouldn’t be watching, but I couldn’t help it.

Could he see us? I wondered. Was he up there, touching himself, looking down at his wife and the babysitting, lying topless on the beach together? That’s when he stood. I nearly gasped out loud as I watched thick, white streams of fluid erupt from the tip of his engorged cock and splash down onto the balcony and the railing.

His eyes never left mine.

“Mrs. B.” My voice trembled as I sat up. “I’m gonna go cool off. I’ll be right back.”

I stood, not sure I could stand, but I did, forgetting I was topless. I walked, a little unsteady, toward the water and waded out into the cool waves, up to my neck. When I looked back, Mr. Baumgartner was gone, but Mrs. B was still watching me, shading her eyes from the sun.

When she waved, I waved back, feeling that steady, rhythmic pulse between my thighs. The coolness of the water only served to make the heat between my legs more pronounced. I floated on my back, watching the clouds drift, letting the waves rock me and once in a while overtake me. When I finally had the courage to get out, Mrs. B had gone into the house, and the beach was empty again.
