Losing [M] Virginity to my sisters Ballet [F]riend

This story happened right after my High school graduation and 14 days after I had turned 18 (about 5 years ago). To understand the full story though we need to go back even further. My sister, 2 years older than me, had a very tight knit group of friends that she began hanging out with when she joined her new ballet studio when I was in 2nd grade. Because my parents really liked all of their parents, it meant that our families spent a lot of time together so I basically grew up with 5 sisters, rather than just one. This story will focus on one particular friend, Kerri. Through out the years Kerri matured quite well into a beautiful Blonde who had a soft roundish face, blue eyes and long slender legs (similar to most ballet dancers). At the time of this story she was probably 5’6” 120lbs and very large breasts for her small frame.

Since my family has a pool I would see my sisters friends in their Bikinis often and it wouldn’t be awkward for them to walk around our house with hardly any clothes on.
