Her first group experience

We were young, it was her birthday so I took her out, we were having a few drinks and taking to a friend, we decided to go driving around drinking the girlfriend was sitting in the middle of us, she leaned forward to make her another drink and I reached back and undid her bra. She wasn't happy but I told my friend to help take it off her slides his hand and grabs her bra, she tells him she's has to get the straps off before it'll come off. While she's doing that I can see he's feeling her out. We're still driving around and drinking I tell her to unbutton her blouse she just looks at me, I told her he's already felt them and you have beautiful tits so you might as well show him. She finally unbutton her top and her tits start showing. He starts playing with them and sucking on her nipples, she has him makes her another rum and Coke. She has a skirt on so I feel her leg and say her leg felt as smooth as silk. I can see my friend feel her leg slowing working his hand up her leg, After while I feel her leg hitting mine, I look down and she has both legs spread open. She leans over and whispers in my ear to tell me he has his finger inside her. I just ask her if it hurt and if she's wet. She tells me she's wet so I told her to lift up and I'll pull down her panties so he can finger her good. He starts working on her pussy and I can get her moen, we ended up at his house and she asks if he was going to fuck her,I said yes. We both took turns on her, that's what started turning her in to a nypho lol
