In the the pool

Big Mac saw her dive into the pool and swim next to her friends, he was confused. She dived in too and also swam over to the girls. Pinkie was the only one in the water, the rest were on deck chairs. Pinkie was waiting at the walk with sudductive eyes. His cock was so hard right now, he always knew his sister's friends were hot but he was going to get to see one nude! He swam over to her. He was about to walk when pinkie reached over the side of the pool and got a bit of paper and a pen, once he woke something she handed the wet paper to him. He could just about make it out, her hands were wet and some of it was ruined. It read
