It was early in the afternoon on what was a glorious summer afternoon with clear blue skies, a cool and gentle breeze blowing and the sun seeming to bath the area in a warm yellow glow. While it was hot in the sun, Dave didn't feel at all uncomfortable as he walked along the shaded path and up to the front of Mary's house. The house itself was a large double story brick building with a huge front veranda set down a slight hill and much lower than the neighbouring houses. The tropical looking garden afforded sufficient privacy by preventing anyone on either side of the house to see into the yard and most windows. It was really quite a nice house and the sight of the pool in the backyard was quite appealing on such a pleasant, warm afternoon.
As Dave strode down the short driveway and around to the side door, he worried that he was arriving too early. Mary had asked Dave to help her with maths while she was at university and Dave had been tutoring her for almost a year. While the extra cash was good, Dave simply enjoyed helping Mary and felt great satisfaction at seeing Mary achieve at the level he knew she could. But Dave had run a few errands that took less time than expected and found himself arriving forty minutes early. But as Dave had walked to Mary's house, and it was a twenty minute walk home, he decided that he might as well knock and see if Mary was ok to start early.
"Oh, hi Dave, I wasn't expecting you so early." Mary said cheerfully as she opened the door for Dave.
"Sorry about being so early, I ended up getting through a few errands quicker than I thought I would and decided I'd head across a bit early. Were you able to start a bit earlier today or should I come back in a while?"
"I can't start the tut just now as I need to go down to the post office before it shuts. I was actually just about to go now sorry." Mary replied.
"All good," Dave said. "I'll burn off some time and come back in forty minutes or so." "Oh no, you don't have to go and come back. You can stay here and have a drink or something until I get back. It's too far for you to go home just to turn around and come back."
Dave thought for a second or two about what to do. The idea of walking twenty minutes to then turn around and walk another twenty minutes back was not appealing. So Dave accepted Mary's offer to wait until she got back.
"Head through to the study. There is a TV or some magazines if you want something to entertain yourself." Mary already had her car keys in hand so Dave went in while Mary closed up behind him, got into her car and left.
Dave went through into the study. It was a small living room in the downstairs section of the house which had large glass doors which opened out into the pool area. The staircase from upstairs was at one end of the room where the study desk was situated in a small hollow of the wall near the glass doors. At the opposite end of the room, a large TV was mounted on a small wooden cabinet with large bookcases on either side. Directly in front of the TV was a chocolate-brown suede lounge chair which would sit two people and to the side of the lounge at an angle to the TV was a single-seater leather recliner.
There would be very little worth watching on TV at this time of the afternoon so Dave decided to sit on the computer chair at the study desk near the windows and write a few notes for the tutorial.
"It's about time you left!" Dave heard someone state in a muttered tone as they began jogging quickly down the internal stair case.
Dave wasn't sure whether the statement was being directed at him nor who it was that was saying it. He spun around in the seat and was about to say something when he stopped dead in his tracks and his jaw dropped open in surprise. He couldn't speak, even if he had wanted to, the shock of what had suddenly occurred stopped him. Alison, Mary's younger sister, had walked rapidly into the room, marched straight to the TV, put a DVD in the machine and quickly sat back on the leather chair without turning around or shifting her focus from the TV. She also carried a small pouch which she placed on the chair next to her.
Now, it wasn't the fact that she had completely ignored Dave that surprised him, nor that she seemed almost desperate as she murmured encouragement to the TV to turn on faster. It was the fact that she was completely naked and completely oblivious to Dave's presence!
As the DVD began to load, Alison slouched back in the chair and spread her legs wide apart, running a hand down from one of her small but perky breasts to her stomach and onto her smoothly shaved vagina where her slender fingers began making slow circular movements over her now spread pussy.
Dave was still in shock. He still hadn't moved or made a sound; he simply sat and stared in awe at the stunning brunette that lay before him. Alison was only a year or two younger than Mary and had just started studying business at uni. Dave always thought she looked like the business sort with her dark brown hair cut short, her short but slightly shapely figure seemed made for the wonderful curves that a business suit affords and the large black rimed glasses she wore added a sense of nerdy innocence which Dave thought quite cute. Now fully naked and exposed before him, Dave could see just how wonderfully proportioned her petite body was. The wonderful contrast of her fair skin against the dark leather chair seemed to make her glow.
As the DVD began playing, Dave found himself staring in disbelief again. The image that appeared was not some random porn video that he was expecting Alison to play; instead the image was that of Mary wearing only a bikini top but naked otherwise and her legs folded to hide her pussy from view. Next to her was another young woman with long blond hair in a pony tail draped over one shoulder and who was also completely naked. The woman, whom Dave had never seen before, got up from the bed they were sitting on and picked up the camera and moved back over to Mary.
"Come on Mary, let's see you use those toys babe." The blonde behind the camera said seductively to Mary.
Mary smiled and without hesitation, spread her legs wide apart exposing her beautiful pussy which had a small patch of neatly trimmed pubic hair above it. She picked up a small blue buttplug from a towel next to her and carefully covered it in lubricant from a bottle next to the bed. As the camera moved closer to Mary's now visibly wet pussy, Mary laid back on the bed and slowly ran the tip of the toy around the opening of her anus, moaning with pleasure as she did so. She inserted the plug deep into her ass while running her fingers quickly over her clit.
"Oh my god, it is a sex-vid! Oh wow, Mary you are such a slut!" Alison said aloud to herself with a cheeky chuckle.
Dave had almost forgotten about the fact that Alison was completely naked on the chair in front of him and now saw that she was lubricating the same blue buttplug as Mary was using on the video. It then clicked in Dave's brain that Alison had obviously found a sex-tape that Mary had made along with Mary's toy collection (which was in the small bag Alison had walked in with). Alison now mimicked her sister as she rubbed the plug around her ass before slowly easing it in.
