There was another crack in a wall that faced the sea, and I looked through. I could see the two girls running on the sand. To my great relief, they didn't head to the location where the nuns were sitting. Rather, they ran straight to a group of their friends who were playing a ball on the beach.
I could see the group gathering around the two girls, and then all of them, about a dozen girls, surged forward in a mighty stampede towards the cabin where I stood naked, their exhilarated shouts filling the air. In a moment, they arrived, passed by the wall I was spying through, and burst into the women's section of the facility. I heard them being pushed to peek through the gap in the wall.
"He is not here," they chattered in disappointment.
By this time, I had completely lost my erection due to the stress, so I moved to the spot where Lisa and Maggie saw me before, turning my back to the peeking girls.
"Here he is," one said, "but can see only his butts."
I stayed in that position and started to play with my dick. The giggling and laughing behind me caused it to react quickly. In less than a minute it got to an upright position. I decided to try upgrading the game.
Still with my back to the girls, I walked to the bench where I left my belongings. I took the bottle of shower gel I brought with me and turned to walk to the shower stall. This move gave a full glimpse of my erection to the girls squeezing by the cracked wall, but only for a few seconds.
A big "wow!" was heard, followed by cheers:
"I saw him! I saw him!"
"I saw everything!"
"It's standing up!"
"It's so big!"
And then:
"I didn't see."
"Let me see too, move away, Lisa, you saw this already."
