I am a 25 year old guy and my girlfriend is 22.
This happened when she was visiting me on a Saturday night. She got us some expensive alcohol and I was ready for her with a few rolled joints. When she cross fades, she turns into this sex driven nympho-minx and she knows how much I love that.
I had bought her some lingerie for tonight. It was a really slinky thing that hugged her pussy real nice from the front and was pretty much like a G-string from the back. Now before we venture further into the details of this night, let me tell you this girl has turned me from being neutral between boobs and ass, to a total ass-man. She has the most gorgeous, tight and curvy ass one can imagine and I go crazy for it. So, panties which show off her ass as much as possible are my favourite kind to get for her.
