Last night was the first time that Lori and I got to spend the entire night together. She is the bff of my younger sister 13 and our parents are out of town for the weekend. We have been getting flirty for over a year even though I’m 16. Their birthdays are a day apart and they had a pretty good party this year. The three of us have fooled around for almost a half a year when I found them making out, their hands down each others bikini bottoms and their tops pulled up. My sister and I were able to get her to go as for as oral with us and all rubbing each other off as well as breast play. My sister and I have been having full s** for almost two years. She said that she and her bff had been fooling around a little. Curiosity, practice kissing, and limited touching. But she wanted to have s** with her. We set it up for this weekend alone for her and I to deflower her virginity for her first time, and we enjoyed it immensely. Then when we were finished hours later, after her special night she helped me wake and f*** my sister, who came forever with our doing her together, then she went right back to sleep. We went to my bed where I did her one final round and we slept. Now I’m cooking a late breakfast hoping to wake them up and get the day started.
