My time alone, my parents away for two weeks at some camp or something, my sister staying with her best friend for two weeks and I am alone house sitting. I’m Andy and 18 years old awaiting placement into uni. I was alone, naked in the pool laying down on the blow up lounge, eyes closed, listening to the sound of nature, think about my forthcoming move to uni.

What is that sound? I think as I hear voices? They are inside the house. I went to move when the sliding glass door opens and my sister is home with three of her girlfriends all in bikini, if you can call those micro swimmers that. I roll off the lounge being naked in front of my sister. I yell “Sis what are you doing here?”

Angela, her best girlfriend and a black hair, blue eye beauty replied “Joyce I thought you said their were no males here?”

Joyce, my sister, a blond beauty, with blue eyes stated, “That’s only my brother Andy. He does not count.”

Angela walked to the pool edge and looked at me. My view was straight up her sexy shaped legs to a bridge opening at her micro bikini with shaved pubes, no tan lines, then up to her 34 dd boobs with super nipples poking out. That made me hard as I have always liked Angela. She said “Enjoying the view?” I stepped back and she saw my hard cock, all 10 inches poking up in the water to her super sexy body. I smiled not saying a word.
