It was early Saturday morning. I had slept in late since my wife and daughters were away visiting her parents for the weekend. I had just got up when the doorbell rang, so down I went to see who it was.

“Are the girls playing out?” cheerfully asked Narelle, from over the road. Narelle was 15, 2 years older than my eldest daughter, tall, with a lovely slim body, firm, round, large breasts for a girl her age, a cute ass & lovely long legs.

“They’re at their grandparents this weekend.”

“Oh, I forgot!” Narelle said, a look of disappointment on her face, “See you later.”

I went back upstairs to grab a shower & no sooner had I climbed out of it, the phone rang.

“I’ve got a problem with the computer”, said Narelle on the other end of the line, “could you come & have a look for me”. “Ok” I replied, “Just let me get dried & dressed first”.

I was over at her house within 10 minutes & went up to her bedroom with her to look at the computer. “I can’t get this new game to work” she said, “The picture’s all funny”. I checked the specs of the game with what the computer had & found that the graphics card wasn’t good enough.

“I think I’ve got a spare at home I can try”, I said, “I’ll take this old one out first & then go & get it”. I removed the old graphics card from the computer & turned towards Narelle, who was sitting on the bed with her knees pulled up to her chest. My eyes were immediately drawn to the white knickers I could see beneath her short skirt, though I must have only looked for a second before making eye contact with her. She must have noticed as she was smiling, “I’ll be back in a minute” I said & left as quickly as I could.

I returned a few minutes later with another graphics card & fitted it into the computer. “Let’s see if this makes any difference”, I said, looking around to her. She was sitting in the same position but this time there were no white knickers under her skirt, just a clear view to her pussy. I was having trouble knowing where to look, so turned back to the computer & switched it on, my eyes never leaving the screen while it booted up. Once it had loaded everything, I tried the game & it worked perfectly.

“There you go”, I said, “Give that a try & let me know how it goes”, trying to look at her face all the time. “Do I owe you anything”, she replied, “Not if it doesn’t work properly”, I said.
