I had known the family for years, having met them soon after Tim and Pam got married. Pam was pregnant with their first child, who I had seen grow into a beautiful young woman called Jenny. 18 months later, Juliette was born, then a break of 4 years before they had their only son, Jake.
It was soon after Jenny's eighteenth birthday when Tim announced that he had to go away to the States for a while on business. They hadn't had many chances to go away as a couple since the children were born and saw this as an ideal opportunity. Now that Jenny was old enough, she could look after the other children. Jenny, however, wasn't happy; her 'A' Level exams were approaching and she had been studying hard to achieve the grades that she needed to go to University. She really didn't want to be spending this important time watching out for her younger siblings.
So, they turned to me; asking me if I would house sit, as well as generally keep an eye on the kids. They were all very sensible and responsible, especially the girls.
"It's really just keeping a watch for Jake," Tim told me, "the girls can look after themselves.
They had a beautiful house, huge garden complete with swimming pool and it was only about five minutes walk from where I worked. I happily accepted.
The first day I was there, Jake was unwell and by the time I got in from work, he was already in bed. Jenny was taking a break from her studies and was watching some trashy TV with her sister. The girls were very alike in their appearance – no one could ever dispute that they were sisters – but they also had their differences.
I tried to avoid staring as I looked at the two of them sitting on the sofa.
Jenny sat in her black top, very slim, with small but perfectly formed breasts. Her baggy grey track suit bottoms did not do justice to the pert arse I knew she had. Her long, wavy hair was dark and, as it usually was, was tied up at the back of her head. She also had dark piercing eyes, which often made her look moody. To be fair, she often was moody, but rarely nasty or unpleasant with it. In fact, she was quite a shy young lady, just getting her to say hello could often be quite a struggle.
Her younger sister was wearing a pair of blue jeans. Not as slim as Jenny (but certainly not fat), she had an altogether 'softer' appearance. Her breasts (currently underneath a fairly tight white top) were larger than her sister's; her face rounder and her hair longer.
They were quite a picture.
In fact, although there was a hint of 'wrongness' in my mind, the thought of sharing a house with them for the next three weeks was quite turning me on.
Jake said he didn't want to eat, so the three of us shared a meal hastily collected from the local Indian take-away. As soon as we had finished, Juliette announced that she was also feeling a little unwell, "I think I'll take an early night," she said.
Jenny, as expected, went up to her room to return to her books.
It was a warm summer's evening and I sat in front of the TV watching a film, the best of a bad choice of viewing. Soon I became bored of it and thought I'd better check that everyone was ok, especially as two of them weren't feeling well – I'd hate to think of anything going wrong whilst they had been trusted to my care.
All 3 rooms had their doors open to different degrees to try to allow a little cool air to penetrate the mugginess of the evening. Jake's room was shrouded in darkness and I could hear the regular breathing which told me he was soundly asleep. Leaving the door open a little, I walked past Jenny's brightly lit room. She was sitting at her desk, back to the door, obviously concentrating hard. I smiled to myself, thinking how wonderful it would be if everyone her age were as conscientious.
Juliette's room was set slightly away from the other two, so I moved across the landing. Her door was half open, with just the dim light of a bedside lamp escaping from the darkness.
I poked my head around the door and at first could hear nothing, but could faintly see Juliette lying in bed on the other side of the room. Looking closer, I could see the thin sheet covering her moving as she breathed. Satisfied, I moved to turn away, but as I did I heard a low moan come from the direction of the bed. My first thought was that she really was feeling unwell, but then a second moan definitely had a slightly more familiar sound to it. It was not a moan of pain, but of pleasure.
Telling myself that I needed to be sure I leaned back around the door and stared intently at the bed across the room. As my eyes grew used to the dim light, I noticed a movement, sometimes fast sometimes slow, just below where Juliette's stomach would have been. My suspicions were confirmed; Juliette was playing with herself.
I know that I should have just walked away, but I couldn't, I was transfixed. Her hand was moving faster, her hips starting to move steadily on the bed and the moans became more frequent.
I was actually quite surprised. I have no idea why as it was a perfectly natural thing for a girl of her age to do, but I suppose I had just never expected to catch her doing it. I stayed watching her and listening to her for a few minutes, not really realising just how hard I was getting until my erection became quite painful in my jeans. At that point my hand, almost as if by its own will, reached down to undo my zip. Suddenly, my conscience got the better of me, and I left Juliette to climax in private. I was sure she wasn't far away.
I hastily went into Pam and Tim's room, which is where I was sleeping, closed the door, removed my clothes and began to stroke my now incredibly hard cock furiously. It was perhaps the shortest wank I had ever had, but an incredibly satisfying one. The thought of Juliette writhing in orgasmic pleasure made me come harder than I had for a long time.
I lay there glowing, partly in pleasure, partly due to the heat and short spell of exertion. It would be a good idea, I decided, to take a shower!
The shower was warm and relaxing and it slowly brought me back down to earth and my heart rate started to return to normal. I dried myself off, but found that, as so often happens, the heat just made me continue to sweat. I draped my robe loosely across my shoulders, but couldn't bear to tie it at the front.
I left the bathroom, and decided to head for the relative coolness of the bedroom. But before I could leave the bathroom, thoughts of Juliette once again entered my mind, and I was almost tempted to go and have another peek and listen. I managed to convince myself that she would have exhausted herself by now and would be asleep, but even that thought was enough to make me hard again.
Leaving the bathroom, I turned to close the door and, as I turned again to head across the landing, I almost jumped out of my skin. Jenny had just walked out of her room and was facing me, just a couple of feet away!
For a second, I forgot that my robe was hanging open, but suddenly, there was the realisation that Jenny was standing there in front of me, looking down at my huge, throbbing, erect cock!
I looked down at her and saw her blushing. "I'm so sorry," I blurted out quietly. With that, I closed the front of my robe and hastily headed into the bedroom. Looking over my shoulder, I saw Jenny turn and head back into her room too.
I stayed in the bedroom for almost an hour. I was worried. What would Jenny do? What did she think? What would she say? It had been a genuine accident, but who on earth would believe that?
I heard Jenny go downstairs after a while and I had thought of just staying in the bedroom and facing things in the morning, but I decided that not only would they not be any easier in the morning, but that also my chances of getting much sleep that night were almost zero.
So, I put on a pair of shorts and a loose T-Shirt and headed downstairs. I had decided not to say anything until Jenny did, at least until the next day. I wanted to try to find out if she was angry, embarrassed or just amused.
