Sis was 20 and I was 23. I didn't live at home anymore, so when I got to mom's I was looking forward to a dip in the pool. Mom worked the graveyard shift at the hospital, so I figured I had the pool to myself. I stripped off my clothes and dove in. As I was swimming around, my sister came through th sliding glass doors, stripping her clothes off. She didn't know I was there because I ride the bus to mom's. I didn't say anything till she was completely naked. "Sup sis?" You'd of thought I slapped her. She almost fell down. What are you doing here? She asked. Same as you, I suppose. I told her. She turned to leave and I said, you take the shallow end I'll take the deep end. Deal? Reluctantly She agreed. I leaned back by the edge of the pool, and grabbed my phone. Scrolled a few minutes and settled on porn after watching my sister stand waist deep with her nice tits just staring at me. I pulled on my cock watching her more than the porn. She asked what I was doing, so I told her to come find out.
