Sally tried as hard as she could to remember when she first started to have a “sitting down” problem, but it was so far back that she finally gave up and accepted she had a problem and how it started didn’t really matter to her at all.

It had started in her mind at special events like birthday parties or celebrations. Then, she remembered her doing it at times when she was traveling on a bus or in a car or even one time on a train.

The whole thing was silly from her point of view.

Still, her girlfriends and her sister confronted her on it one fine day and she realized it was something that was not normal for a well behaved sixteen year old young lady to be doing in public or even in private.

It gave her pause to consider her friends words.

Sure, it was a sexual thing. She could easily see that now. It had become a habit now and she was truly addicted to it. It was something she knew would be difficult to stop doing because she had so much fun in doing it with certain guys.

All she knew was that she was not ashamed of doing it and she didn’t feel the least bit guilty about her actions. She knew it was not something she had learned by watching other people do it or even reading about it in a book or a magazine. It was part of her, and it was second nature to her now and she had no intention of ever stopping.

None of her selected partners had ever rejected her advances and they all seemed totally happy about letting her have her way until the happy ending.

Lately, she had even modified her undies to make it easier for her to satisfy her hunger for a quick result. She knew the whole thing was good for her libido and good for her physical health.

Sally was a girl with an urge to sit on men’s hardness wearing short skirts and flimsy undies to get the full effect of their equipment on her feminine mystique.

She usually made a game of it like when she was a little girl and she would shout out, “Sally wants a ride!”

Her uncles were thrilled at her cowgirl motions, and they enjoyed her laughter and giggles from start to finish.

Now, that she was an almost adult, she had a wider bottom and infinitely more curves to satisfy any male’s need for female companionship.

She usually picked out relatives with discretion or friends of her father with oversized equipment to really make her day. Sally loved doing it to men in uniform. Any uniform would do, a cop, a security guard, a military guy or even a bus driver.

Most of the time she was satisfied with the man’s equipment staying inside his clothing.

Sometimes, when she had this uncontrollable hunger inside her belly, she reached back and unzipped the man’s fly to allow his thing to flop out in a semi-hard state that immediately sought her feminine folds or her tiny, crinkled opening. At times like that she usually reserved her pretty bottom for close friend’s only giving her a taste of oral satisfaction with all the lights turned off and absolutely no conversation to be heard in the dark.

Sally rode the male laps with an innocent look on her face making those around her smile thinking she was just a girl wanting to have some fun. Her mother suspected her intentions and approved of her actions because she had the same inclinations when she was a teenaged girl.

Of course, after the mother got married, she forgot all about that foolishness because her husband was quite demanding of both anal and oral sex, and she was generally to exhausted for such fun and games.

Now Sally was sitting on her Uncle Harry’s knees with her skirt down modestly covering her privates and her beautiful female thighs. Only Harry and she knew that his hardness was pressing against her pucker hole with definite desire to probe her rectal depths.

She laughed and made jokes with her sister and brother at the same time distracting attention from the fact that her lower body was bouncing on a grown man’s dick with serious intent.

Sally remembered that Uncle Harry was one of the first partners that had entered into her anal paradise with his thick knob at her fourteenth birthday party at a time when she was still exploring her sexuality. She had come close to exposing her sins because his creamy load hitting inside her rectal passageway triggered a grown-up orgasm that she experienced for the first time ever.

Harry knew he had caused her emotional break-down and held her hips firmly to hide her tremors of total release.

Sally managed to make a joke about her father taking a second helping of mashed potatoes even as the waves of sensuous passion ran amuck inside her diminutive teenaged body.

After that evening, she always sat on Uncle Harry’s lap whenever he visited, and they both enjoyed the fruits of “sitting down” fun like naughty children with a brand new toy.

Recently, Sally had been subdued in mixed company because the confrontation with her friends had startled her into questioning her own behavior. She was becoming more and more reclusive and secretive about her relations with the other sex. One exception was her older brother Tommy who was a little slow in his thinking process but made up for it with unusually large muscular development.

Sally was giving her brother a nice massage letting her fingers run over his defined muscles and eventually getting down to business with his oversized cock. He had a stupid smile on his face as she took care of his stored up deposit of cream milking him with her skilled hands like a milk maid with special talents.

Tommy liked his sister’s loving hands on his junk, but he was afraid of going further because it was all too much for him to understand the explosive feelings inside his loins.
