PENNY
I was surprised when Sian entered through the side gate: walking quickly up giving me a hug and kiss she sat opposite me.
"Penny it's necessary that we find someone who can model the large size lingerie and I seem to remember you telling me that your younger sister is a C Cup, and also very pretty can you tell me more about her."
"Well yes she is as you describe but she isn't what you are looking for. You see she is incredibly shy almost introverted. When we were kids and our parents had visitors around, she used to hide under the table our mother jokingly called her 'mouse'."
"You know people can be trained to get over those troubles."
"She got married at twenty-five and was still a virgin. Her marriage is a disaster because her idiot husband is more interested in horse racing than sex. She comes round her crying I suggested she shaved her pussy and dressed in sexy night ware: that was a disaster."
"Have you tried to seduce her? That may bring her out of her malaise."
"I have been trying to seduce her since her eighteenth birthday, but she always has a crying fit."
"Listen invite her to a rather exclusive beach party. Come around to the shop and we will select a new and slightly naughty bikini. We got the latest summer fashions last week: actually, this is what we need her for."
"Well, she loved the idea of sexy lingerie so I think that would attract her to the beach party."
Later that morning Marina and I went to Sian's shop where we selected much to Marina's embarrassment a very brief red bikini and a white one which really showed up her deep tan. Sian also selected two new bikinis for me and two seersucker beach robes. As Marina's husband was at an interstate race meeting, she came around to my house to discuss the beach party and what we should bring with us. Knowing how shy and reserved my sister is I didn't reveal the real reasons for the party. If she had known the idea was to get her to join Sian and Elise's lingerie business as a model, she would have hidden under the bed.
As we drove down to the beach party, I gave Marina a brief history of the house we were visiting. As part of Sian's inheritance, it was an isolated solid brick beach house that ran down to a small crescent-shaped bush lined cove. She called it her holiday cottage but in reality, it was a large five-bedroom house whose bricks had been lined in concrete many years before. Painted a light pink it had been used as one of the local fisherman's reference points ever since it had been painted. It was beautifully designed with a broad glass-lined veranda looking down to the beach and out to sea: during Spring and Summer Sian and Elise used it as a place for photographing publicity for their beachwear lines and as their quiet retreat from the busy city.
The morning was warm and sunny promising to be a magnificent day to be on the beach. Knowing how much the success of the party meant to Sian and Elise I was speechless at how much trouble they had gone to. Having arrived the evening before they had had a solid wooden table and bench seats carried under the inviting shade of a giant Moreton Bay fig tree that spread its massive limbs across the sand at one end of the beach. As Marina and I walked down to the white sandy beach we noticed a crew of caterers preparing salads and desserts for our lunch spotting
grey smoke curling out from the tall chimney of the old stone barbeque where they were roasting meat for our main course.
On arriving we all decided to take a swim in the delightfully warm water of the small cove. Standing waist-deep in the water I noticed Sian and Elise admiring Marina as she shyly removed her beach robe revealing her very brief white bikini that barely covered her pussy while her breasts were only just decent. At first, she looked about her as though she wanted to run away and hide until Elise taking the lead suggested she join me and Sian in the water.
My sister is five foot nine inches with long dark hair flowing over her shoulders. Her face is round with dark eyes while her most interesting feature is her smile which displays a chipped front tooth that had been caused by a bicycle accident when she was thirteen. Ever since the chip which is quite prominent has caused her much embarrassment regardless of my telling her that it just made her sexier and more desirable. Where I have big DD breasts my sisters are only C Cup although she is incredibly pretty it's unfortunate that her main problem is her incredible shyness. Elise recognizes this and is determined to help her get over it and in turn introduce her to the Sapphic world and modeling profession.
Hearing the call to lunch we walked up to where a large table had been set up with three Bain Marie's and big salad plates and bread. Recognizing my sister's incredible shyness which went as far as to make it difficult to select items for her plate Elise took the opportunity to commence her quiet seduction. Placing two plates in Marina's hands she placed a selection of meat salad and bread on each plate then pouring two glasses of Pinot Noir she led Marina to the far end of the big wooden dining table where she started to ask Marina some questions while they ate their meal.
THE SEDUCTION
"So, Marina Penny tells us that you are married."
"Well yes but ..."
"What are you saying?"
"My husband loves horse racing and most nights he is down at the club watching replays of the day's races and placing bets on the next meeting. This weekend he's in Melbourne attending some race meet."
"It sounds as though your sex life is virtually non-existent."
"You could say that."
"Have you ever thought of the other team? After all, Sian and I are lesbian while your sister is bisexual her first time was with Sian and me why not experiment and possibly branch out: that way you would be keeping it amongst friends"
"Penny is bisexual ... no way."
"She's just over there ... ask her."
"So, you both seduced my sister."
"Not really. We live next door to your sister and one day she noticed us making out on our veranda. She invited us round for a pool party: it just happened and now the three of us are lovers."
"Your sister would love it if you started modeling as well: we really do need someone to model our medium to large range. Marina, you are so pretty ... you would be perfect."
