Susan had waited for her mom to leave. As soon as the coast was clear, she went to her mom's bedroom and got out the vibrator from the night stand. At 18, she had been doing this for a long time.
Her mom and dad had split up years ago and mother and daughter had been on their own ever since, and they liked it that way.
Back in her own bedroom, Susan quickly took her clothes off and lay back on the bed with her little plastic friend. She opened her mouth and pretended the vibrator was a real cock. She licked it all around, closed her lips around it and then let it slide into her throat. She had done this many times but never to a real one. In fact, she had never even seen a real one, but that was all right, she had a good imagination.
She took the vibrator out of her mouth, turned it on low, and let it make contact with her nipples. She had very large breasts which she would have thought the other girls at school would envy, but instead they made fun of her.
"Um," the vibrator made her nipple hard. She figured she didn't need the girls anymore than she needed the boys. "Uh," the vibrator soon had both of her nipples hard.
The vibrator seemed to have a mind of its own as it made its way slowly down her stomach and rested on her reddish-blonde pubic hair. She could feel the gentle vibration all through her. Even though she still only had it set on low, it felt good.
Her hand slid the vibrator down lower so that is was just touching the outside of her pussy. The gentle vibrations felt delightful. Her clit was starting to tingle and a delicious heat had started to spread through her.
"Umh," Susan sucked in her breath as the vibrator gently touched her pussy lips. She spread her legs a little as the vibrator made contact with her clit. "Oohh, that feels good."
She was always wet by the time she had the vibrator at this point and a long sigh escaped her as she slid it inside of her. The vibrator made its way in slowly, gradually, a little at a time. The pleasure would build agonizingly slow, a hair's breath away from painful.
Susan closed her legs with most of the vibrator buried deep inside of her. She reached beside her bed and grabbed her headphones. Turning her music on, she slipped her headphones over her ears. With her vibrator filled pussy sending ripples of pleasure through her and her music filling her head, she closed her eyes and played with her nipples. This was how she had planned spending her afternoon and she was contented. Her mom had wanted her to go shopping but she told her she had plans. She just didn't tell her this is what they were.
Dan was the baby of the family. Ever since his big sister and her husband had split up, he had been the one she depended on to fix things that broke. He was pretty good except when it came to plumbing, for some reason he just couldn't do it.
She had asked him to come over and clean out her furnace and ducts. She replaced her own filter but she hated the smell that came out when you switched it from cooling to heating. He loved his sister and his niece, so he guessed there were worse ways to spend a Saturday afternoon.
He let himself in and headed through the house to the basement and the furnace. He used to have to explain to his sister that without the right kind of equipment he could only clean so far. He had gotten tired of having to say the same thing every year, so he just bought the right equipment. It had turned out to be a pretty good side business.
With a puzzled look on his face, he stopped and listened. What was that noise? No one was supposed to be home, his sister and niece were out shopping. All of the rooms were on one floor of the house with an unfinished basement that contained the washer, dryer and furnace. He stopped outside of Susan's bedroom, which he had just painted a month ago. The noise was coming from in there but he still couldn't figure out what it was.
He opened the door and just stood there staring. There was his 18 year old niece lying in bed, she was totally naked and was playing with herself. No wonder he didn't recognize the sound, she had a vibrator inside of her.
He couldn't take his eyes off of her. The longer he stared at his niece the more he wanted to look, she was pretty! He had never noticed it before, and her tits were huge! Damn! When had that happened? He had noticed she was big on top, of course, but never associated his niece with sex and just didn't think about it.
He went over to the bed and just watched her playing with her nipples. With the headphones on her and her eyes closed, she didn't even know he was there. It was a complete turn on.
Susan was really getting into what she was doing. Her vibrator fill pussy was throbbing and she had her nipples standing at least an inch out from her breasts. She would have to turn up the speed on her little plastic friend before long.
Dan reached down and took one side of the headphones away from her head. "What the fuck are you doing?"
