My girlfriends little sister is a terrible flirt when my girl isn’t around. I honestly wouldn’t mind doing her even if she is only 12. She is a very pretty brunette with little budding breasts and a plump little b*** that is just beginning to get some curve in her hips. She is smart and fun to flirt with when we can talk freely. She has even asked a little about our s** life, and my s** life before I started seeing her sister. Once, it was obvious that she was braless in a skimpy little camisole and sleep shorts totally making sure that I noticed her and her lovely petite body. She said that she had never even had a real kiss from a guy before, so there wasn’t much she could add to our flirting. Mostly it was me making her squirm talking about s*** things and how much I would like to date her. When she suggested that I come over the other night when her mom and sister were both working I decided to go for it. I just turned 18 and my girl is 16 and still a virgin. No other males in the picture. I had to pick up my girl at 10:30. Their mom wouldn’t be home till after midnight. I took her a couple bottles of wine like she asked and had rum for myself and a good bit of smoke for both of us. She wasted no time getting frisky so I had to slow it down just a touch telling her that I didn’t want to hurt her sister. She and her sister both wanted me and wanted to loose their virginity with me at the same time. I wasn’t sure I believed her. A few minutes after we kissed a little and I sucked on her n******, her sister came home as a big surprise to me. They were ready to get the party started. They had set it up hoping I would go for it. We all began to make out and the girls were already getting undressed. As it turns out they had made out and fooled around before. We had to air out the house before mom got home cause it reeked of s**. Good thing the m*** is kind of flirty with me too since I was there when she got there. Only her daughters virginitys were missing.
