It was Friday, it was a sweltering hot day, and because I hadn't been able to concentrate on my work I'd decided to take the rest of the day off. This wasn't hard to do because I work at home most of the time, with just a few occasional visits to the company for meetings. There was another reason for my inability to concentrate, but that one would be rectified on Monday.
My daughter Jenny and Anne, her friend of many years standing had retreated indoors some time ago in order to try on the new swimsuits which Anne's mother; Susan had given them on the preceding Tuesday as presents for their Eighteenth birthdays.
They were born on the same day, and met on Jenny's first day of school. I met Susan that day and after a week I realized that her house was very close to mine so I offered to do the school-run for her daughter as well. I'd been doing the run ever since and the girls were now more like sisters than merely good friends.
Diverting any incoming call through to the house phone, I locked the large cabin at the bottom of the garden which serves as my office and headed for the house to have a shower and some lunch. On the way to the bathroom I passed my daughter's bedroom and was comforted by the sound of giggles emanating from it. Considering that the new school term commenced on the coming Monday, that was a good sign.
Jenny and Anne were similar in every way except for appearance. Both were intelligent, polite girls and they both had single parents. The difference between them was that whilst Jenny was a slim, lithe, red headed dynamo, Anne was half a head taller, with yellow blonde hair, a very shapely body and long legs.
I admit that I lusted after her, but I never did anything about it.
Returning from the shower I called out that I was about to make lunch which was greeted with a scuffling noise, accompanied by Jenny calling out that they would be down in a moment.
We spent the afternoon lazing about on the patio. They may have been relaxed, but I certainly wasn't. They had both changed into shorts and Bikini tops and I was having a hard time, literally.
Anne went home and Jenny and I had dinner, after which I went down the garden to the office to check that I had everything I would need for a meeting with a client in the morning. On my return I looked into the living room, and stood watching my daughter. Jenny was facing the TV, but her eyes were closed and she was panting as, with her legs wide apart, she rubbed and pressed against her sex.
I spent a couple of minutes watching her pleasuring herself then I quietly withdrew, returned to the house door and made sure I made noises as I walked back to the living room.
Jenny has had to manage growing up without her mother, who died when she was eight. I had done all that I was able to do, but as girls grow up, there are things which I know they would have a difficult time discussing with a male.
I had been incredibly fortunate that Jenny had Anne as a very close friend because her mother had taken Jenny under her wing when anything of female matters arose. I had dreaded the time approaching when I needed to consider buying her underclothes and sanitary items, but Susan had taken that problem off my shoulders.
As a thank you I had invited Susan and Anne to our house each Saturday for a meal after which we spent the rest of the evenings either playing cards or watching a video.
Susan had several small part time jobs which helped to swell the allowance her ex-husband paid her. She had a small car, but hadn't been able to use it for other than school runs and travelling to work. This was why I had offered to take over the school run with Anne.
Jenny was now pretending to be interested in the TV programme. I went to sit beside her and told her that I needed to have a serious talk with her.
"Jenny, I came to the door of this room a short while ago and I think you know what it was that I saw you doing. I'm not shocked, upset, or angry. What I am is concerned that you were doing it in an absent minded way in less than private surroundings. I could have had a visitor with me which would have embarrassed you terribly.
You've never shown any indication that you were experiencing feelings of arousal, until today. After you and Anne had spent a lengthy period of time in your bedroom, you both decided to wear Bikini tops and lounge in front of me to see how I would react. What really happened in your room?"
Jenny's face was flushed red, which, with her hair colouring, was quite a sight.
"Anne came and said that she had something to tell me and something to show me, but I had to promise to never tell anyone. I did promise."
"That won't work Jenny; I won't repeat whatever you tell me unless I think it's something Susan should know, in which case I'll tell you that I'm going to do it."
She knew she would have to tell me sooner or later, and opted for sooner.
"Anne said that she'd gone to bed early and left her mom reading. She woke up and went to go to the bathroom and heard her mom moaning. She opened her mom's bedroom door and saw her stroking her clitoris and pushing a finger into her vagina.
"As her mom's fingers rubbed harder and faster on her clitoris and the fingers on the other hand moved in and out of her sex tunnel she was panting and moaning which covered the sound of her bedroom door being opened and then closed again.
"When she got back in bed she couldn't stop thinking about what she'd just seen and while she thought about it she started to rub her sex. She realized that she was getting hot and wet down there and that it felt so good that she didn't want to stop.
"She said that she wants to do it again and wanted to show me what she'd been doing and to show me how to do it. I had no problem with that, I love seeing her and her mom when they're undressed, it gives me a funny feeling in my sex.
