My sister had her best friend for a sleepover yesterday, and for tonight, while our parents went for a long weekend to get away. Mia is a very pretty 12 almost 13 year old like my sister, and she has a nearly silent crush on me. She is a very strawberry haired blonde where my sister Sami has luxurious light brown hair. Both girls kept their hair to the middle of the back long. Samantha confided to me that she wanted Mia to be her first lesbian experience, but was to shy to make a move on her alone. They were both petite girls with very alluring, lithe figures though Mia was a little more developed and curvy in the b*** area. I would love to experience the girl as well, so we were going to try together. I knew that Sami is 5feet one and 105 pounds. Mia was right around there as well. Not long after a light b.l.t. lunch with chips we smoked some weed and broke out the ladies vodka and my own rum. I am a week over 17, 6feet even and 180 pounds and I have been my sister’s lover for almost a year, having seduced her the day after her 12th birthday. We had always been s******* charged to each other, I just worked it to our present level. So far I have been her only. My girlfriend is a knock out 5foot 4, 115 pound brunette 16 year old I have enticed to learn about s**. They were sharing the couch when Sammi handed Mia a fresh drink over her shoulder, she looked at me nervously, and she came so close to chickening out. My balls were tingling in anticipation. When she reached around Mia with both hands to squeeze and fondle her her breasts, my c*** grew quickly. “What?- mmmm – what are you doing Sami?” Mia was pretty buzzed while Sami and I had remained mostly sober. They were both looking at me. Sami still caressing her when she said, “Something my brother and I have wanted to do for a long time now.” She didn’t look to surprised. “You mean you too,.. not.. not just Buddy?” A smile curving her sensually full lips. “Ooohhh this is,.. oh-my-god.” Sami leaned over her and sucky kissed her slender neck. Mia moved to set her drink down and turn to Samantha and kiss her.
