After almost a month of semi-weekly training, Keitaro had fallen into a rhythm with his training with Nilüfer. He quickly learned that he needed to follow her regimen and obey her rules perfectly, or he would face the consequences.

It was annoying for Keitaro to acknowledge but she was actually a great trainer, she had a firm but gentle manner about her and never hesitated to praise you when you did something right. But the intensity of her workouts was always an issue for him, he often had to put up with a lot of pain after a session. "That bitch is going to kill me at this rate..." he muttered to himself as he tried to get out of bed the next morning.

Today's session was special, to this day, they had trained at the local gym but today, Nilüfer invited him to her home with a weird and cryptic message that said "Time to get intimate with the iron my little trainee! Today's session will be at my house today at 11 AM sharp. Don't be late." with a winky face emoji and a pouting face emoji at the end.

Keitaro didn't question it, he figured she just wanted a break from the routine at the gym.

He arrived at her address at the appointed time and knocked, he was quickly greeted by Nilüfer who was wearing a short pair of teal spandex shorts and a sports bra that showed off her impressive voluptuous figure. "Man, is she hot... She lost a ton of weight in the last few months, her body looks fucking amazing now; she looks like a whole new person" Keitaro thought to himself as he tried not to stare.

"Oh, there you are!" she exclaimed, "Come in! Don't worry my parents are on vacation, it's just us! We'll be able to train without interruption," she said enthusiastically as she pulled him into the house.

Her house was big and opulent, "Her parents must be loaded" Keitaro thought as he looked around. Nilüfer guided him to her home gym. It was cozy, tasteful, and had a pretty impressive setup, it looked like it had everything you'd need to get in shape. "Wow, this place is amazing!" he exclaimed, "You have every equipment possible here, why would you even need to go to a gym?" he asked incredulously.

"I just like the atmosphere of a gym better. It's more motivating for me. But I also do some serious lifting here at home." she explained, "Anyways, enough chit-chat, let's get started! We'll start with some stretching to warm up, then we'll move on to the main course." she said as she turned on some music, got on her yoga mat and started stretching.

Keitaro followed her lead and started stretching alongside her. He tried his best not to stare at her body but it was hard, she was bending hard and her big butt was sticking up in the air forming a perfect heart shape. He could see her thong peeking out from her tight teal shorts as she stretched and the more he stared, the harder he got. "Fuck, I need to stop thinking about her like this... Remember... You fucking hate that bitch for all the humiliations she put you through," he thought to himself as he forced himself to look away.

It was in vain though, all of a sudden he felt an irresistible urge to touch her ass. He had already kissed it in other circumstances, but now he needed to feel it with his hands. He reached out slowly to grab it as she was in her descending motion. Right at the moment he was about to lay his hand on her butt, Nilüfer let out a long and loud fart right in his face. Keitaro's hand froze in mid-air as the stench of her fart hit his nose. He was completely motionless, trying to process what had just happened.

Nilüfer continued stretching as if nothing happened "Oh, I'm really sorry about that! I had beans for lunch and they often make me very gassy, I hope it doesn't bother you," she said playfully, her back still turned to him.

Keitaro just stood there like a statue, trying to comprehend what had just happened. "Did... Did she just fart on me on purpose? to punish me? or is it a coincidence?" he thought to himself as he stood there in the lingering smell of her fart.

"Alright enough warm-up, let's move on to the main dish," Nilüfer said with enthusiasm as she put her yoga mat away and walked to the weight rack, "Today we'll be doing barbell squats, a very important exercise to muscle and tone your legs and butt. I'll first show you how to do it with proper form, pay attention." she explained casually as she demonstrated the proper squatting technique.

Keitaro watched her as she squatted down and then back up, her ass looked absolutely amazing. "I bet she knows exactly how good her ass looks in those tight little shorts," he thought to himself, "She's probably doing this on purpose to tease me." He was getting more and more frustrated as he watched her.

"I can feel you're not very focused on my form there, Keitaro... Maybe you need a better view," she said ominously, "Lie down below me and watch my technique closely, you might learn a thing or two."

Keitaro's heart started racing as he realized she wanted to squat right over him. "O-Okay..." he replied anxiously. He lay down on the ground and stared up at her, his eyes glued to her face.

She slowly lowered herself down towards him and her ass rested briefly on his torso before she continued her squat. Her crotch was so close to his face he could smell her sweet scent. He felt the pressure of her whole body on him as she squatted up and down.

"Uhm I'm learning a lot... but this is a bit dangerous, you might slip and crush me," he said nervously.

"Shut up! I'm in the zone right now!" she snapped at him.

After a couple more reps, she exclaimed slightly out of breath, "Ok now, turn the other way around, you'll get to truly ASSess my squat form, hahaha got it ?"

He quickly turned around, he was now staring directly at her massive ass. From this angle, it looked even better, rounder, and plumper, it was mesmerizing. She paused there for a few moments, "Enjoying the view?" she asked lewdly. Without waiting for an answer, she slowly lowered herself down, her ass now just inches from his face. in a swift motion, she then planted her ass firmly on his face for a moment. He experienced a tremendous pressure on his face and the overwhelming warmth of her butt, it felt like his nose was going to cave in.

"Ughhh" he grunted.

"Am I squishing you?" she asked with a giggle, "Well too bad, you're just gonna have to get used to it. I still have plenty of reps to do."

And with that, she started squatting up and down again, her ass bouncing on his face with each squat. He could see her thick ass cheeks jiggling and bouncing with each squat, it was hypnotizing. It was getting very uncomfortable but he didn't dare move.

"Ugh I'm feeling gassy again," Nilüfer said annoyed as she continued to squat.

"Uh oh" Keitaro mumbled.
