Heavy Training
Everything about Josh's life changed the day he walked in on Liz's private workout. She had figured out how to use orgasms to enhance her workouts, and Josh was more than happy to assist by becoming her workout partner and lover. As he thought back over the past two years, some episodes did stand out clearly in his mind.
The first weeks were a delightful, never-ending whirl of sex and muscle as they harnessed sexual tension to intensify their workouts. They soon realized that they had to make allowances for the limitation of human endurance. Liz could stay in a state of almost constant orgasm during their sessions for two reasons: first, because she was female, of course, and second, because she already had months of practice using a strap-on vibrator. Josh, in contrast, was only male, although with the benefits of youth and raging hormones.
They had discovered that Josh could usually manage two climaxes during their one-hour gym time, so they eventually figured out a good pattern, favoring Liz because she was still in training for the upcoming cheer squad Nationals. First, Liz would give Josh an oral orgasm to start off the morning. His favorite lifts for receiving oral were bicep curl and bench press. Needless to say, he made great progress in both during those weeks, and he soon broke the four-hundred pound mark. During that first part of their session, Liz would keep herself stimulated by wearing her vibrator, and she would provide inducements to Josh by doing a gradual striptease, removing an item of clothing only when he exceeded his best number of repetitions for a particular weight.
Around the middle of the session, Josh would orally pleasure Liz, usually to a new personal record weight in whatever lift she wanted. At the end of their session, she wanted a final climax with him inside her, so they made a game of testing out each piece of gym apparatus to see whether it was conducive to intercourse. They found many that were so ridiculous that they rolled off laughing and just did it on the floor, but they did find a few favorites, including her sitting on his lap for bicep curls. The absolute best in this category, however, were lat pull-downs and shoulder presses; in either case, she could sit on his cock on an adjustable bench. The changing forces during the exercise drove her deeply onto his cock with every repetition.
With Josh's continual praise of her naked physique, Liz developed enough confidence to enter a local figure competition in the swimsuit category. She easily walked away with first place, and the day after the contest was the first day they skipped their workout. Instead, they spent the morning pleasuring each other on the gymnastic mats. At that competition, the judges advised her that at the state level, although she would probably place high in swimsuit, she already had almost enough muscle to win the fitness category. As a result, as soon as Nationals were over, with her team placing an incredible third overall, she began training for muscle size as well as strength.
In the subsequent months, Josh and Liz learned about bodybuilding supplements and proper diet, so that as they increased in strength, they also added muscular size and definition. It was unnerving to Josh, however, that she was making more rapid progress than him. At first, he just chalked it up to the beginner's training effect, where the body initially responds quickly. He could see, however, that their difference in bench press, which started at one hundred thirty five pounds, was less than a hundred pounds now, and she showed no signs of slowing down.
