My Girlfriend's Sister is a Slut

Georgia's no priest, that's for sure. The girl's got a great pair of tits and she's definitely not shy about showing them off - which is a bit of a problem given that she's my girlfriend's younger sister.

I'd been going out with Sarah for a few weeks when she decided it was time for me to meet her parents but it was Georgia who made a real impression on me. "Do you like my T-Shirt?" she asked, unzipping her sports jacket to reveal a thin white top which was stretched obscenely-tight across the heavy curves of her braless breasts.

The teats of her erect nipples were sticking up like bollards.

"Jesus Georgia, put them away," Sarah scalded, but her sister never really did; not when I was around anyway.

Sarah had a small bust and it was obvious that her younger sister felt compelled to compete with the assets that she'd been born with; there were plunging necklines, the tightest of tops, obscenely sheer material, yet never a bra in sight.

"Look. Georgia. What do you want me to say?"

"That I've got a nicer ass than Sarah."

"You know I can't say that," I replied, grateful that my jacket was covering the crotch of my trousers. There was a reason that I couldn't pass comment - I hadn't seen my girlfriend from those angles.

The final straw came when Georgia decided to put her pussy on display. In my experience, girls don't forget they're not wearing underwear, and sitting crossed legged while she was reading her dad's Sunday newspaper was just asking for it.

"You don't even like football," | said, pushing down the top of the paper as she somehow managed to look innocent while giving me an uninterrupted view of her shaved snatch. "But you do like playing games.

"Who says I'm playing games?" she challenged.

"So, you're going to let me fuck you?" I asked, trying to put the frighteners on her.

Georgia gasped, clearly taken aback, but she quickly gathered that inner cruelty. "Yes," she said with a nasty sneer. She draped a leg over each arm of the chair, positioning herself in the most obscene way yet.

Taking up the challenge, I dropped to my knees, unzipped my flies and pulled out my fully-erect cock, positioning it between ...
