Kelly, pt 3 by superbuff muscleswell@buffbody.com Party at Club SB On Kelly's seventeenth birthday, she unveiled her and Aaron's gym. "Club SB." SB for Super Buff. All buffest kids were there. The DJ's were pumping rhythm, and the clientele were pumping weights. SB was the first club/gym that catered to the SB crowd and was the toast of underground LA. It was located in the basement of a 80 story high-rise in downtown. Phoebe showed up with two guys in tow. She had huge, firm, all-natural tits that seemed to defy the laws of physics, and muscles to match (or, overmatch). At sixteen, she had 19" biceps, a 23" waist with grid-iron abs, and she weighed 178 solid, sexy pounds. She could bench-press 600lbs for 3 sets of 12 reps, and squat double that. She wore a super tight, bright red jump suit with bright blue sneakers, her hair and nails were also dyed bright blue to match. Kelly was even more impressive in the muscle department. She had crafted for herself a physique that would be envy of any bodybuilder. She was massive and cut. Kelly's arms were 20 solid inches of dynamite. Her chest was incredibly thick and powerful. Her abs formed a plate of bullet proof armor, and her legs were cut, hard, and huge. She could bench press 750lbs for ten reps and squat 1400. The SB drugs (SBDs) were breaking down all barriers to muscle development, and Kelly and Phoebe were as strong or stronger than their boyfriends in most upper body exercises, and dominated in leg development. Both women worked out for hours every day. Resting just long enough between workouts to recuperate. Of course the SBDs speeded recovery to 1/4 of the usual time, so they needed only one hour of rest for 4 hours of gym time (plus the usual 8hrs). Kelly's birthday instigated a marathon, 12 hour, all night orgy/workout. After eight hours, the boys were starting to tire. But, Kelly said, "You know what? We're at the bottom of an 80 story high rise, and I have access to the stairwell." All the boys groaned. Aaron lasted the longest, and he gave out at the 23 floor. Kelly and Phoebe were leaping up 4 or 5 steps at a time. They had to be careful not to hit they're heads on the cieling. At the 60th floor, Phoebe cried out in pain. Kelly looked back, she had been out pacing Phoebe for the past few floors. "Come on! You can do it!" yelled Kelly. Phoebe closed her eyes and focused. Seven more floors, and she broke the barrier. Her whole body was singing as she and Kelly burst onto the roof. The cold night air felt exhilirating on their bikini clad bodies (their other clothing having given out to their expanding muscles long ago). Kelly let out a yell that could have been heard on the street below. Phoebe had a funny expression on her face. "I...we...giggle...did..." she began to shake as a massive orgasm of muscular growth rocketed through her body. She started to scream something, but her voice caught. Her legs collapsed, and Kelly caught her. Suddenly, Kelly started to shake too. Both women fell to the roof, their sweaty, massively muscular bodies writhing and vibrating against eachother. Wave after wave washed over them for nearly two solid minutes. Then both supergirls blacked out.
