The woman entered the room, and with a knowing smile teasing her full lips, she sank into the comfort of the plush chair in the corner.
The handsome stranger turned, having sensed her approach.
Locking his steely grey eyes on hers, he moved slowly toward her, his experienced gaze measuring her, hypnotizing her with his soft murmurs of assurance.
He sank to his knees before her and without a word, smoothly released her from her constraining attire. With a sigh of surrender, she allowed his foreign hands to unleash her bare flesh. He expertly guided her through this tender, new territory, boldly taking her to heights she had never dared to dream of, his movements deliberate, confident in his ability to satisfy her every need.
Her senses swam. She was overcome with an aching desire that had gone unfulfilled for so long. And, just as it seemed that ecstasy was within her grasp, he paused, and for one heart-stopping moment, she thought, "It's too big! - it will never fit!"Then, with a sudden rush, it slid into place as if it had been made only for her. As pleasure and contentment washed over her, she met his steady gaze, tears of gratitude shining in her eyes.
And he knew it wouldn't be long before she returned. Oh, yes, this woman would want more. She would want to do it again and again and again...

Leaded gasoline

In 1921, tetraethyl lead was first given a laboratory test as an anti-knock additive to gasoline fuel. The knock in the one-cylinder laboratory engine was utterly silenced. Even at a strength of only 2-3g grams per gallon (1000 to 1 dilution), it had a remarkable ability to quiet the relentless knocking. This invention of Thomas Midgley, Jr., of the General Motors Research Laboratories, located in Dayton, Ohio, was first put on public sale as ethyl gasoline in the same city on 2 Feb 1923. This invention of leaded gasoline came after seven years of testing at least 33,000 compounds. Previously, on hard acceleration, an engine sometimes made knocking, popping or crackling sounds, which sapped power and could damage the engine.
