It didn't take long for Zack to guess Jack's email password. He soon found some messages that lead him to Jack's SBD supplier. He let Diesha take it from there, and soon Zack, Diesha and Cindy had a regular supply of SBD. Diesha went a step further, though. She had Zack trap any messages to or from Jacks supplier and send them to her.

With each passing week the workouts grew longer and more frequent. By the end of the third week, even Zack was working out three times a day. And each was getting stronger and stronger, and more and more muscular. By the end of the third month, Cindy had become nearly superhumanly strong, and her body was thick and curvy with muscle. Diesha, was just a little smaller than Cindy, but also supremely strong and muscular. Zack was far behind the two women, but was stronger than the average man his size, and he had the physique of an amateur, lightweight bodybuilder.

...Jack answered the door. He swallowed hard, seeing Diesha standing as tall as himself in her spiked heels. She was dressed in a tight, little, see-through pink dress, and a tiny white bikini underneath. She had transformed into one of the most amazingly muscular women Jack had ever seen. Her body looked like one of Jack's favorite bodybuilder's, Mah-Ann Mendoza. Her whole body was a symphony of curvy muscle. He hadn't seen her for nearly two weeks, and he was stunned.

Diesha hardly waited a heartbeat before she was all over Jack. Her power was undeniable. Jack started trembling as he realized that she was stronger than him"”easily stronger. She thwarted his every attempt to either feel her up, or fight back; and in-between she was tearing his clothes off. The last time they fucked she pushed him so hard to defend his macho dignity that he couldn't walk for a while in the morning. He felt his pants fall around his ankles, and felt her hand on his erection. She snapped the waistband of his underwear over his prick and he inhaled sharply in pleasure. Then she pushed him--hard.

With his pants around his ankles, he lost his balance and fell. When he looked up he saw two women standing over him, the other was Cindy. If Diesha looked like Mah-Ann Mendoza, then Cindy looked like Andrulla Blanchette. Her body looked so power-packed, she looked like she could walk through a brick wall. She wore a black microskirt and a cobalt blue lycra t-shirt stretched tight over her amazing upper body. In her black and blue ankle boots, she was a little taller than Jack.

"Wow," said Cindy, "I think you really knocked him out!" She leaned over and kissed Diesha.

Jack's jaw dropped. Cindy and Diesha started flexing and feeling each other's bodies. When his mind began to recover a little, he tried to get up, but Cindy kicked his feet out and he fell back down. Diesha picked up his feet by the pants bunched around his ankles, and began to drag him backwards on his back. He tried kicking and squirming, but Cindy picked him up by the wrists, and all he could do was swing back and forth. He couldn't believe how easily he was handled by these two incredible women.

"Did you call Zack?" asked Diesha, as if bored.

"Somebody say my name?" Zack stepped through the doorway. Jack was scared now. Zack wore a tight t-shirt and jeans, and he was huge. Jack took an immediate hatred to Zack's air of self-confidence.

"Jeez, Jack, you shouldn't look at me like that. Both of these women are stronger than I am."

"That's right, pussy, you shouldn't have messed with us."

Jack stopped struggling. "B... but you... How did you...?"

"What do you mean, "˜how?' you idiot? We took Super Buff drugs."

"But I've been taking them too!"

"No, you haven't, you moron. You've been taking placebos. We interrupted your supply, or I should say Zack did."

"You little...!" Jack shouted at Zack.

Zack just laughed, "I'm not little anywhere." He patted his package and flexed his bicep. His sleeves became thin and made little ripping sounds.

Diesha commenced a series of poses, flexing her amazing muscles. Zack worshiped each body part flexed, licking and kissing Diesha all over. He unzipped his pants, and flipped himself into a handstand. She yanked his pants off in one swift movement, and he flipped back onto his feet. He wore only a little posing brief, and the embossed imprint of his hard member showed through clearly, a small cum stain on the front.

Jack had never felt so outclassed by people he considered inferior to himself. Zack, because he was a geek; Diesha because she was his assistant, and a woman; and Cindy because she was younger than himself, a teenager, and female. To make matters worse, Diesha and Cindy were making his dick rock hard.

Diesha started hitting the weights hard. After each exercise she would flex and pose for Zack, who would worship every inch. The poundage was amazing, Diesha was obviously "Ëœsuper' in SB parlance and some of Jack's home weights could not come close to testing her actual strength, especially in squats and bench press.

Cindy smiled, and joined in. Jack just stood there, pants around his ankles, a huge hard-on tenting his jocky shorts. His head was hung in defeat and he started to cry out of jealousy when Cindy benched 350 lbs for ten reps.

"Feel that bicep she demanded, flexing her arm in front of Jack's nose." She was loving how good she felt. It was a rush to be so big and strong. She knew she could easily kick Jack's ass, and that turned them both on. Jacked judged Cindy's bi's to be 17 inches around. He was sobbing as he touched her soft, warm skin with hard muscle underneath. She smelled incredible, and the pheremones nearly made him come on the spot.

He lifted his head towards Cindy's arm and tried to kiss her bicep. Cindy grabbed him painfully by the jaw. "I said, "˜touch', not "˜kiss'," she chided, and threw Jack, all 195 lbs of him, to the side like a rag doll.
