Karl opened his eyes and saw a cunt in front of his face. He could smell its strong musky aroma. The lips were glistening with moisture. As he watched, a single drop oozed from the pink fleshy folds and stretched out a bit, before it fell with a splat on the yoga mat in front of him.

“Am I doing this right, Domino?” Karl asked. Domino, his personal trainer, had told him to get on his hands and knees, arch his back and look up, while he inhaled through his nose.

Karl was trying to get into better shape. It had been a year since Hester had left him. He had put seven years of his life into that relationship, and she had walked out on him. Maybe he should have known better than getting involved with her in the first place. Hester was very religious, and Karl was a devout atheist. Hester had given him a couple of blowjobs when they had first started going out, but towards the end, she would only do missionary, and that was only after he pleaded with her for days. She thought he was oversexed. Karl thought sex once a day was barely enough to keep his prostate healthy. Once he suggested she tie him up and give him a spanking. He had ended up sleeping on the couch for a few days. Of course, it turned out, she had been fucking her way through half the congregation down at the Lutheran church. Figures!

Karl had been in pretty rough shape after the break up. He started drinking more, smoking more, and started spending more time at the bar. He even spent some time out behind the bar getting high with some unsavory acquaintances. It was a car crash that finally snapped him out of it. Nobody was hurt or anything, but he decided he needed to make a change in his life. On New Year’s Day he quit drinking, smoking, and getting high. Quitting tobacco had been the hardest thing. He spent two days in bed without any cigarettes in the house.

By March, Karl felt like he was ready to get into a relationship again, but he felt extremely inadequate when he looked at his online profile. He was shocked at how much weight he had gained. He had seen pictures of guys online with abs. He wondered if there might be some abs hidden somewhere beneath his gut.

“You should try Domino,” Frank suggested. Frank was Karl’s coworker at the metal working shop.

“What’s that?” Karl asked.

“Domino is a personal trainer,” Frank replied. “She has the best workout routine around. You should try her out. She whipped me into shape in no time.”

Karl had to admit that Frank seemed to be in pretty good shape, and his attitude in the shop had improved lately too.

“That sounds like just what I need,” Karl said. “Does she charge very much?”

“She is a little expensive, but like I said, she is the best,” Frank told him.

“How can I get in touch with her?”

“I have her number in my contacts. I’ll send it to you.”

“Does she have a gym or something?”

“No, she will come over to your place.”

“The routine mixes traditional calisthenics and yoga poses with my own special touch,” Domino explained.

Karl stared at her with his mouth open. Domino was wearing a leather corset that barely contained her bulging bosom, a leather miniskirt with a slit up the side, knee-high leather boots with five inch heels and long black leather gloves. Not too typical for a workout outfit. She had dark red lipstick on and her black hair was tied into a ponytail. She had a leather bag with her that looked kind of like an old time doctor’s bag.

She took some special workout shorts out of the bag and told Karl to put them on. 

“No underwear,” she warned him. “That will interfere with the workout. No T-shirt either, you need to be bare chested.”

Karl started to leave the room but Domino intercepted him.

“No need to be shy,” she said. She made him strip down and put on the training shorts in front of her.

Karl thought they seemed more like underpants than workout clothes. They felt about two sizes too small for him, but he was able to squeeze into them. The shape of his private parts was clearly contoured by the shorts.

“We will start with some push-ups. Roll your fingers down to your palms and put your thumbs over them to make a fist. Now get into a push-up position with your knuckles on the ground.”

Karl had done knuckle push-ups before, so he felt fairly confident about doing them.

“I am going to do a count. When I say ‘one’, I want you to bend your arms and touch your chest to the floor,  when I say ‘two’, I want you to push back up with your arms straight.”

She started a brisk count, but it wasn’t long before Karl fell behind. He felt a sudden sharp pain and heard a loud crack! as she hit his left butt cheek. He looked up and saw that she had gotten some sort of riding crop out of her bag. The kind he had seen used on horses.

“What the hell!” Karl yelled.

Crack! The crop impacted his right butt cheek.

“You will not speak, unless I say you can speak,'' she commanded him.

Karl found out that he would get hit if his belly or legs touched the ground, if his chest did not touch the ground, or if he fell behind in the count. He also noticed that his rod grew a little stiffer with each stroke of her rod.

“Ok, that’s enough,” Domino said, after twenty push-ups.

Karl could feel his buttocks radiating heat after his spanking, though his workout pants had probably protected him from the worst of it. Domino was staring at his crotch, seeming to make an assessment.

“Next, you do sit-ups,” she said. “Lay on your back, cross your arms so your hands touch your opposite shoulders. On my count, touch your elbow to your opposite knee and go back down again.”

It didn’t take long for Karl to fall behind in the count. Domino paused and looked at him severely.

“We’re going to have to try this a different way,” she said. “I’ll help you.”

Domino took a pair of small clamps linked by a chain out of her bag. She squeezed Karl’s nipples until they would fit into the clamps, then screwed them down nice and tight. That really got his attention. The chain dangled down across his chest.

“One!” Domino said, and as she said it, she pulled on the chain, pulling Karl to a sitting position. Karl let out a cry of pain. She was pretty much lifting his upper torso by his nipples.

“Good,” she said. “Now, go back down.”

Karl tried to lie backwards, but Domino held on to the chain connecting his nipples. She gradually gave way, but his nipples were really stretched out by the time his back was on the floor. She let off the tension on the chain for a moment. The clamps had slipped out, so they were now concentrated near the end of his nipples intensifying the pain.

“Two!” she said and repeated the sequence.

On the tenth sit-up, one of the clamps came completely off. Karl’s poor nipple was completely flattened and throbbing. Domino put her mouth on it and began sucking his nipple. The clamps had made it extremely sensitive. He began moaning and put his hands on the back of her head. Domino responded by biting his sensitized nipple hard, and Karl cried out in pain.

“No touching,” she said, “unless I tell you to. Eleven!” Domino grabbed the clamp that was still attached to his other nipple, and gave it a sharp twist, before continuing the motions as before. By the time she reached twenty, the clamp snapped off of the other nipple. Karl’s nipple was flattened and white. Domino again sucked hard on it to somewhat restore it to its original shape. Karl knew better than touching her this time, but she ended up giving him a little nip anyway.

“Maybe that’s why they’re called nipples,” Karl thought.

“Now I’m going to have you do some yoga poses,” Domino said.

Karl had full chubby going by now and was struggling in the confining shorts. Domino seemed to notice his problem.

“I’ll help you with that,” she said. The shorts had a flap in the front like you see on men's briefs. Karl had always wondered if anyone used those for anything. He was about to find out some people did. Domino reached down his pants and pushed his erect cock out through the little opening. Sheesh! She was not shy at all. Karl thought there was no way his balls were going to fit through that tight little opening, but Domino was able to squeeze them through one at a time. She took an elastic band from her hair and pushed it over Karl’s cock and scrotum. She pulled on the elastic and twisted it to form another loop, which she stretched over his ball sack. She ran her finger around the elastic to make sure there weren’t any bits of skin getting pinched.

Karl looked down at his manly bits in their confinement. He was only average sized, but that elastic made him look much larger. His cock and balls were turning a reddish purple color. Domino squeezed her thumb and forefinger around the base of his shaft, and gradually brought them up towards the head. When she did, Karl noticed a large glob of precum oozed from the tip of his mushroom head. Domino took one of her fingers, scooped up the glob of precum, and pushed it between Karl’s lips. Karl had never tasted his precum before and was surprised that it didn’t taste all that bad. A tad bit salty maybe.

“Sit cross-legged with your right leg on top of your left.”

Karl crossed his legs, but there was no way in heaven or in hell that his right leg was going on top of his left. To his amazement, Domino was able to get it into place for him.

“Now press your palms together,” Domino said. “Namaste.”

“What does that mean?” Karl asked.

“Some translate it as ‘I salute the divine in you.’”

Karl pressed his palms together and looked down at his erection. “Namaste,” he said.

“Close your eyes and inhale… hold it… exhale. Breathing is a key part of yoga. When you breathe in, you will be able to stretch out your joints and your spine. When you exhale you will be able to move farther. Try to lean forward as far as you can.”

Karl opened his eyes and found Domino crouching in front of him. She had removed the cups from her corset, so her bulbous tits were right in front of his face. She had large areolae and large erect nipples. Karl was impressed with how far he could bend forward, as he tried to bring his face to her cleavage. Just as he was about to make it, Domino moved backward quickly. Karl lost his balance, but ended up doing a face-plant right between her tits.

“Now I want you to do the cat-cow pose. Get on your hands and knees.”

Domino removed her skirt. She had some sort of harness underneath. Domino grabbed Karl by his hair to get him into position. She took some massage oil and rubbed it on her gloves. Karl looked down between his legs at his dangling boner. He did kind of resemble a one-uddered cow.

“For the cat pose, exhale and put your chin on your chest while arching your back upward like an angry cat.”

Karl attempted the move. Domino reached over him and grabbed his dangling cock with her oily glove.

“For the cow pose, inhale and look upwards while pushing your belly towards the ground.” Domino pulled downward on his cock to emphasize the motion. Karl closed his eyes, as Domino rubbed her oily gloved hands over the tip of his throbbing cock.

Karl smelled a strong musky aroma when he inhaled. He opened his eyes and saw Domino had positioned her cunt directly in front of his face. She had a shaved pussy, and her brown wavy lips were glistening with moisture, her pink opening was visible beyond them. If he stuck out his tongue, he would be able to lick those sweet juices. His mouth began to water. He watched as a drop of fluid formed at the bottom of her pussy, and dripped down onto the yoga mat with a splat.

“Am I doing this right, Domino?” Karl asked.

“Very good,” Domino said. “You are progressing so well, I think you can add one more thing to this move. As you switch between cat and cow, I want you to lick up and down on my pussy.”

Karl began licking upwards during the cow pose, ending on Domino’s little clit and circling it with his tongue. For the cat pose he licked downward, until he was probing her puckered little asshole with his tongue. Domino helped him by grabbing his head with her hands. Domino was moaning with pleasure as Karl licked her. She seemed to really be enjoying her work. Hester had never let him lick her. She had always said it was disgusting.

“The next pose is the down dog,” Domino said. “Stand with your feet a little wider than your shoulders, bend over, and put your hands flat on the floor.”

Karl attempted the position, but his knees would not straighten out. Domino moved behind him. It turned out, the exercise pants had some sort of flap on the back. It reminded Karl of a pair of long underwear he had as a kid. It was called a union suit, and it had a little flap on the back in case you had to go number two. Domino took down the flap and began rubbing some oil against his butthole. He heard her get something out of the bag. Karl was beginning to wonder how long he could hold this pose. He looked over at Domino and saw she had a big black dong strapped around her hips.

“Uff-da!” Karl exclaimed.

“Uff-da indeed,” Domino replied.

She began pushing the oily dildo against his tight butthole, until it seemed to pop a little bit, and she was able to slide it in. Karl let out a low moan. It kind of felt like he was taking a dump in reverse. She pulled back a bit, to give him some relief, before she pushed into him again. After a few strokes, he had loosened up enough for her to impale him to the hilt. He noticed his legs got straighter, as she continued to pound his butthole, until his feet were actually lifting off the ground when she slammed into him. Holy handstand! She finally pulled out and examined his gaping hole.

“That should do it,” she said, satisfied. She pushed a butt plug into his duff to replace the dong, then she moved in front of him. She crouched down and put the dong up to his face. It smelled kind of like the expired Limburger cheese Karl had in the back of his refrigerator.

“Clean it off,” she said.

Karl did his best to lick the dong clean as he held the pose. It was a little too big for him to fit in his mouth though.

“Relax the jaw and inhale,” Domino said. The yoga seemed to be working, for Karl was able to get the whole dong into his mouth.

“Focus on your breathing,” Domino said, as she pushed the dong deep into his throat. Karl felt like he needed to gag, but he focused on his breathing, and the feeling began to pass. Domino pushed it in even further. This time he did gag, but she held it in there, as his throat went into convulsions around the dong. Thick mucus oozed from his mouth and nose.

Domino finally pulled it out, and Karl started coughing. He was kind of embarrassed by the goo all over his face. She didn’t seem to mind though, because she scooped it onto her gloved palm and began slapping Karl in the face. You bet he saw a few stars after that.

“The next pose is the tree pose. Stand on one foot, take the sole of your other foot, and put it against your knee. Point the other knee out to the side. It may help, if you hold your hands out to the sides, then sweep inward and push the palms together.”

It sounded easy, but Karl was wobbling all over. His dick was sticking straight out in front of him, his balls were bulging out wrapped in the elastic, and he had a plug in his butt.

“It will help if you focus on something near the ground,” Domino said. “Look at my right foot.”

Domino was standing in front of him. Her left leg was in front of her bent slightly at the knee, and her right leg was straight behind her. Suddenly, she snapped her right foot out and kicked Karl hard, right in the cherries. Karl collapsed to the floor groaning in agony. He pulled his knees to his chest and rolled around on his back on the ground.

“That one is called apanasana,” Domino said. “The final pose is open butterfly. This is a very relaxing pose. Lie down on your back. Put the soles of your feet together, and pull them up close to your body. Your knees are out to the sides. Don’t try to push your knees down, just let gravity pull them down. Lay your hands at your sides, with the palms upward. Take long, slow, deep breaths through your nose. Close your eyes and relax.”

Domino was probably right. This would be very relaxing, except Karl’s cock and balls were in a very vulnerable position now. He suspected Domino might be planning to kick him again. He decided to close his eyes to help him relax. The elastic was doing a good job of keeping Karl’s cock hard and pointing straight up into the air. He gradually became aware of a moistness on his cock. He peaked and saw Domino straddling him, lowering her dripping pussy down onto him. Karl took a deep breath and pushed up into Domino’s pussy. It felt so good he let out a soft moan. He exhaled, and she pulled up slowly. She began rocking on top of him a little faster, and he began thrusting more energetically. His breathing quickened. Pretty soon, he was slamming into her cunt over and over again. When he started getting close to his peak, she suddenly pulled off of him and squirted her orgasm all over his chest and face.

Domino spun around, so Karl could plant his mouth on her used pussy, while she wrapped her gloved hands around his cock and started pumping it furiously. At the last moment, she pulled the butt plug out of his ass and quickly removed the elastic from his cock and balls. She massaged his sore balls and dick with oil.

“You can cum now,” Domino said. It felt like the elastic had been holding him back, because with a few quick strokes, he started grunting and spurting streams of cum straight up into the air. His back arched, and Domino pushed her cunt hard against his face. Domino began licking the cum up that had splattered on his belly, then sucked the cum from around his cock.

Domino moved around until she was face to face with him again. Karl had never felt so relaxed. He knew this had been the best workout of his life. He looked forward to repeating this on a regular basis.

“Namaste,” she said as she gave him a deep kiss on the mouth.

“Namaste,” Karl replied.
