Zach felt charged the next morning when he met Rui and the others at the dojo just as the sun was breaking the dawn. There was Cesar, a middleweight, Jose, a lightweight, and Aldo, a featherweight. Zach found it interesting that Rui chose to introduce them by weight class. There were also Rosa, a short, muscular, almost breastless, dark-haired featherweight, and Juliana, a taller middleweight with full breasts, grey eyes, and a brunette braid that hung down her back to her waist.
Unused to the heat or the humidity and being out of shape, Zach brought up the rear by quite a way when they finally got back to the dojo.
“I’ll do better,” he promised as everyone congratulated him on finishing at all.
Krista showed up shortly after that, camera in hand, wearing a pair of short shorts and a T-shirt that was ripped off just below her breasts. Not owning anything resembling underwear, as Zach had learned, her thick ruby nipples were easily visible through the material of her T-shirt, as was the underside of her breasts from time to time when she’d lift her arms to take a photo. Everyone quickly ignored her as she wandered around the dojo shooting whatever struck her fancy.
There were a few wolf whistles at first, followed by general laughter, but everyone soon focused on their work and the sounds of grunts and groans, bodies slamming down on the mats, and weights crashing to the floor filled the air. Zach decided that he needed to work on his conditioning first and foremost, having done no serious working out for a month, especially in light of his dismal performance on the morning run, so he concentrated on stretching and the speed bag.
At noon, everyone went out to the street and got manicoba, a famous Amazonian dish. The leaves of the manioc plant are compressed and simmered for few days in order to remove poisonous acid and then cooked with a variety of meat, manioc, sausage, bacon, and chicoria, and served with a generous portion of rice. It was incredibly filling and delicious and cost less than a dollar.
Apparently the schedule called for a break from noon to four when everyone would once again meet at the dojo for the afternoon workout, so Zach and Krista went back to their apartment, falling into a long, leisurely 69, Krista cumming non-stop as Zach sucked and chewed on her long inner lips, teasing her clit and drinking her up, his tongue jammed deep into her, until she finally succeeded in getting him to lose it, filling her mouth with his hot, thick cum which she eagerly and greedily gulped down.
“I think that we’re going to like it here,” Krista sighed as she snuggled up next to him.
“It seems pretty cool,” Zach agreed, “and I like Rui and the others. They’re really dedicated, it seems, and everyone’s been really friendly. But I really feel how much my conditioning has deteriorated.”
“I hope not too much,” Krista said, giggling and rolling away from him to lay on her stomach. “I’m just dying to feel your cock in my ass,” she said, reaching behind herself to grab her ass cheeks and spread them apart.
“My legs can’t take all of this,” Zach sighed. “It’ll have a negative effect on my training.”
“Are you telling me no, that you won’t fuck me in the ass?” Krista asked in astonishment.
“You know better,” Zach replied with a sigh, rolling over to stare at her spread pussy and rosebud as she wriggled her ass at him while continuing to spread her ass cheeks wide apart. “You know I can’t resist you,” he said, leaning down and dragging his tongue up through her sopping pussy to her rosebud, rimming her and pressing his stiffened tongue against her rosebud.
“Oh, god, I just love it when you eat my ass,” Krista gasped in delight as he continued to tease her. “Oh, yes, yes,” she sighed when he replaced his tongue with his cock, easily pressing it into her, watching it disappear into her ass until all 8″ was buried deep in her.
“You are an incredible fuck,” Zach gasped as he pounded her ass, Krista laughing as her whole body bounced off the bed.
“Just keep fucking me, Stud,” she laughed, trying to meet his thrusts but finding it difficult because of the way she was bouncing off the mattress as he continued to pound her.
“Oh, man,” Zach finally groaned several minutes later, his cock buried in her ass as it pulsed, filling her with cum.
“Oh, god, that was so good,” Krista gasped when Zach finally rolled off of her, her ass gaping open and cum running from it onto the bed.
Halfway through his afternoon workout, Zach knew that he had made a mistake in fucking Krista in the ass, his legs feeling weak and trembling as he worked out on the stair-step machine. He could see her smirking at him, realizing what was happening.
“Maybe I should take it a bit easier on you,” Krista said to him when he took a short break, “though my ass feels so good.”
“You’ll pay for this,” Zach panted, glaring at her.
“Really!?” Krista replied, her eyes shining.
“Ready for another run?” Rui asked, coming up to them, his whole body drenched with sweat from his own workout.
“Another run?” Zach asked.
“Like in the morning,” Rui explained. “We always finish the day with a run.”
“Oh, shit,” Zach said, shaking his head and sighing deeply.
“Maybe you should skip it today,” Rui suggested. “You’re not in shape yet. Maybe you’ve been overdoing it,” he said, looking at Krista who smiled at him.
“No,” Zach said. “I can’t let my poor decisions affect working out.”
“Since when is fucking me in the ass a poor decision?” Krista asked, mock outrage in her voice and eyes, Rui’s eyes widening in surprise.
“Fucking that hot ass of yours is never a poor decision, I’ve just got to be more careful about when I do it,” Zach replied, attempting to mollify her.
“I’d think any opportunity a person could get to fuck me in the ass would be the right time,” Krista said indignantly.
“You should probably not say anything,” Rui said, chuckling. “How can you argue with that?”
“See, Rui understands,” Krista said, grinning at Zach’s discomfort. “I’ll bet Rui wouldn’t hesitate to fuck me in the ass at any opportunity, would you?”
“Not a chance,” Rui agreed, blushing.
To his chagrin, Zach had to walk the last few hundred meters of the run, his legs barely holding him up, not seeing any of the others for most of the last half of the run as they left him in the distance.
“You okay?” Rui asked, coming up and resting a hand on Zach’s shoulder as he bent over, hands on knees and gasping for breath.
“Yeah,” Zach replied. “It’s my own fault. Somehow I need to learn how to say no to her.”
