Hot high school sister

I was about 20 and still living at home in the early 1980's. One of my sisters, she was in high school, senior, and laying out in the sun in the backyard. I was sitting at the kitchen table, eating something I guess, and she came in, no one else around, in her two piece yellow bikini and got something out of the freezer at the top of the refrigerator, she lingered a bit with the freezer door blocking her face but I could see her beautiful lean body, nice flat stomach, nice long legs I knew that she was cock teasing me. Awesome, never told that to anyone.
