Time to meet the family!

"It's only us. Sorry we're late," Claire calls out as you enter the porch.

You hear a shrill excited scream emanating from within the house. It grows louder until a lithe long blonde haired girl comes prancing down the corridor.

"Clairrrrrrrrrrrrrrrrrrrrrrrre" What can only be Amy launches herself at Claire giving her a big hug.

"Happy birthday Sis!"

Claire wasn't wrong, Amy doesn't just act immature but also appears a lot younger than Claire, and is definitely dressed for the warm weather - clad in a skin tight long-sleeved white leotard that does leave much to the imagination. She is taller than Claire, her body well-toned and she has much smaller breasts - maybe only A-cups you think.

"So, this is my boyfriend Jack," Claire says almost having to pry Amy from her.

She is obviously not wearing a bra as you can see the tiny nubbins of her nipples, but you try not to look to much as she is the younger sister of your girlfriend after all.

You quickly look up to her cute face, her features are small, her straw blonde hair light and wavy which hangs down past her shoulders.

"Happy birthday!" you say. Unsure how to greet her you hold out a hand to shake.

She looks at it and sniggers. "Oh I say," she says in a mock posh voice, "how very formal you are!"

You withdraw it self-consciously.

Claire, gives Amy a playful nudge. "Amy, be nice."

"Oh sorry, of course. Where are my manners," she continues. She then performs an over-exaggerated curtsy. As she lowers you get another chance to appraise her tits as they hang down - they could maybe even just be in B-cup territory.
