Author's note: Not everyone appreciates May-December stories that involve incest, so if that is you, this story isn't you.
Pieter Strauss III, aka Trey, a young student who had earlier lost his university Professor father, Pieter Strauss Jnr, himself son of another Professor, Pieter Strauss Snr, has a summer holiday fling with a mature lady, Sarah, then later learns on his return to university in September that she is in fact his father's sister - his aunt - and his father's replacement at the university. They decide to live secretly as a couple while looking simply like Aunt/Nephew house mates to the outside world.
This story takes place during the third - summer - session of Sarah's first year teaching and Trey's third year as a student.
After their overnight adventure with Professor Li and his wife, Sarah and Trey's love life had been confined to themselves for a while. But after Easter, as the weather improved, some peoples' attention definitely switches to sex, and both of them were keen to try something else, not because of dissatisfaction with their relationship but simply wanting to explore and experiment. Sarah had been talked, by the Dean, into doing some career counselling work with students, especially those uncertain as to whether or not they were in the right courses or needed guidance on how to proceed. She was scheduled to have one of these sessions later that afternoon, and mentioned it to Trey. "I have a four o'clock with the Boobsy twins today, so why not swing by my office and we'll go out for dinner when I have done with them. I think they might just drive me to drink anyway, from what I have heard."
"The Boobsy twins? Who on earth are....."
"Two girls whose bust measurements probably exceed their IQ. Lord knows how they got in here - would love to know what they wore to their interviews!"
"By the sound of it, probably nothing much!" laughed Trey. "Are you planning I should meet them?"
"Not particularly but they will be in my office till around 5," said Sarah laughing.
Needless to say, Trey was in the hallway leading to Sarah's office by 4:45 but did not head down there. He leant against the wall and waited, about 25 yards or so from the door. Soon enough, the door opened and out came two young ladies, with boobs as Sarah described, trim waists and pronounced hips, and typical young-student blond pony-tails. Both were wearing short flared skirts, and the skirts and the pony-tails swung quite nicely from the hip action as they walked down the hall towards him. They didn't know him, so he looked at them, but didn't acknowledge them, and they walked straight by, but did look him up and down quite carefully as they passed. He turned slightly and watched their swaying hips until they turned the corner. They certainly could almost pass for twins. Then he heard a familiar laugh. "I thought I might find you out here. Young male students are so predictable."
Trey went into Sarah's office. "So, how did your counseling session go?"
"Actually, I owe those two ladies an apology. Yes, they look like people with the nickname "The Boobsy Twins" are expected to look, but I did not assign the nickname to them. They got that from one of their tutors, and it has kind of preceded them ever since. However, I think their IQ well exceeds even their combined bust and hip measurements! They are two fine 23 year-old young ladies who are quite smart and have good senses of humor. Clearly, I am going to have to come up with a better nickname - the Boobsy Twins is insulting and should be buried.
They are studying a fine arts degree with a major in photography, and they both were able to get into the technicalities well beyond my understanding, and at least make themselves look knowledgeable to me. It turns out they need some help organizing a shoot of a male and a female nude outdoors, and are totally unsure where they can pull off such a thing. Apparently the university is happy to set such a project as part of its courses, but not allow such photography sessions on its land. And obviously, the park in the center of town is out of bounds..."
"So you were thinking about our back garden, being as it is private and not overlooked, and has lots of trees around it and even a small pond... and you say we males are predictable! Were you also planning for you and I to be the nude models?"
"You yes, not sure they need an old woman like me, but you're more their age and they could model for each other."
"And what if things get out of hand, or should I say 'into hand'?"
"Then our rules apply, and you can't have them all to yourself!"
"I see, so what date did you arrange?"
"Well, the weather forecast for the week-end is good, so I thought this Saturday."
"And did you tell them you need to ask your nephew if he is comfortable with all this?"
"No, I just figured a good East Indian meal at the Heritage House would allow me to bribe you into acceptance. I did mention I had a young nephew who might make a good male model for them."
"It's a good start. Let's go. I take it you just happened to mention that your potential-model nephew might just be outside the door?"
She smiled. "Come on, I really fancy their mulligatawny soup!"
"And I might just fancy you for dessert. I'm going to drive a hard bargain for all this!"
"Really? I hope so," said Sarah, with a grin, "A hard bargain sounds just fine."
So they had dinner of mulligatawny soup, lamb vindaloo for Trey, chicken madras for Sarah, with cauliflower bhaji to share, and a bottle of sweet Riesling, then headed home for their nightly Jeopardy! au naturel, going to sleep after relieving any stress they were feeling.
Friday, Trey mowed the lawn, and bought in stuff for a BBQ should the ladies need feeding, and Sarah did a bit of housework, which mainly consisted of putting stuff moved around by Mrs. Rowntree the cleaning lady back where Sarah preferred it.
On the Saturday, Trey moved their cars out of the double garage on to the forecourt so the girls could park their car in the garage and be able to carry their equipment direct into the garden. It also meant that by closing the doors of the garage, people could pop naked to the car to get stuff without being seen from the street.
Saturday had dawned bright and sunny, with barely a breeze, a clear blue sky and zero percent possibility of rain. The Boobsy twins, who turned out to be called Jan and Sue and were completely unrelated, turned up around noon. They parked in the front forecourt and rang the doorbell. They were dressed as Trey saw them earlier in the week, in very short skirts and close-fitting tops, and it was immediately apparent to him that they were braless underneath.
Sarah explained about putting their car in the garage, Trey helped unload it, and Sarah put out four glasses of wine on the only part of the garden in shade at that point. As they sat down to get to know each other, Sarah explained where shadows from the trees would fall later in the afternoon.
Over wine, it became apparent that Jan and Sue were kind of a couple. "We're both bi-sexual, rather than lesbian, and not totally anti-men. Probably just anti most testosterone-fueled male students!" said Jan. "So we share an apartment, and most nights share the same bed, but not always. Sometimes one or both of us brings someone home, and sometimes we share..."
Sue looked carefully at Trey and Sarah. "You two are Aunt and Nephew, right?"
Sarah nodded, and so did Trey.
"But that's not all, is it?" asked Sue. "There's something else going on here isn't there?"
Trey looked at Sarah, and smiled at her. "I think we've been sussed out," he said.
Sarah looked at the two girls. "This must not go any further, please, It could damage both our lives, but yes, we are a couple when we are away from the university. It's a long story," She filled the girls in on how they met and had what was supposed to be a without-strings holiday fling without realizing who the other was until after they had a wonderful couple of nights of great love and great sex, a result of an immediate mutual attraction. How they both realized at Sarah's first lecture at the university exactly who the other was. How Trey was Pieter Strauss III, son of Professor Pieter Strauss Jnr, who was her brother and who she was replacing at the university following his death. Both Sarah and Pieter Jnr were children of Pieter Strauss Snr.
The girls sat quietly for a time digesting all this news. Then Jan said "This isn't getting our project done, so let's set up the cameras over there. To begin with I want some pictures while the sun is still towards those trees and not behind them. On a project like this, we work in black and white film - so much more flexibility with aperture and exposure and final processing. Now, are you two still prepared to model?"
Trey nodded. Sarah looked and asked, "Do you really want an old woman like me?"
Sue smiled. "You have a great body, good hair and a genuine smile. You're fit and pleasantly muscular, not flabby at all, and don't worry, we won't pose you together in anything suggestive - not unless it's for your private viewing...."
