On the morning of the second day after the extreme heat hit, inside the artificial cave.
Because the walls were thick enough to insulate against most of the heat, it remained incredibly cool inside the cave.
It was the perfect time to work out.
Bare-chested, wearing only a simple pair of cloth pants, Chuck supported himself on the ground with his hands. His broad, muscular back gleamed with a greasy shine under the sweat.
"Come on, sit on me first."
As his words fell, Valentina and Janet, who were wearing only their underwear and had long been ready behind him, turned sideways and sat down on his thick back, one in front of the other...
Valentina's firm, powerful buttocks tensed slightly as she sat expressionlessly on his lower back. Janet, on the other hand, directly pressed her explosively full, snowy white massive buttocks down entirely. Her two plump mountains of flesh almost covered Chuck's entire upper back. The heavy weight instantly made the muscles in Chuck's arms bulge and tense.
"Baby... does this feel okay? Is it too heavy?"
Janet lowered her head, her red long hair hanging down her cheeks. Her hoarse voice carried a hint of shyness. A pair of plump thighs subconsciously hung down, her rosy, beautiful feet resting lightly on the sneakers she had just taken off, wanting to lessen some of the "burden" for Chuck.
"If he can't even hold up the two of us, then he really might as well wash up and go to sleep early."
Valentina, sitting cross-legged on Chuck's waist, back-to-back with Janet, directly crossed her legs on Chuck's body. She folded her arms across her chest and closed her eyes to rest her mind, posing as if she were meditating.
"Not heavy, tuck your legs up, Janet, I can't balance well like this."
"Oh... okay then."
As Janet braced her hands on Chuck's back, her soft, fat buttocks shifted a bit on his upper back. She gently stepped her feet up as well, carefully sitting with her arms around her knees.
Chuck confirmed the two women were sitting securely. Only then did he take a deep breath, let out a low shout, and explosively exerted force with his arms. He actually started doing push-ups steadily with Valentina and Janet on his back—a 1.75-meter mature mare with large breasts and fat buttocks, and an over 1.8-meter muscular, hairy female warrior, adding up to a weight load of nearly 300 pounds!
With every descent, Chuck's lower back was as firm and straight as a steel rebar. The distinct muscles on his arms bulged with veins. With every rise, he steadily lifted the two women with astonishing power.
Janet's massive breasts swayed as she held tightly onto Chuck's back, letting out bursts of exclamation. Valentina just tightened her abs, closing her eyes and pretending to meditate intently, but a flush on her cheeks betrayed her true feelings.
The full, fat buttocks and firm, fleshy buttocks deformed slightly on Chuck's back with every movement. Sweat formed tiny streams where the three people's skin touched, flowing all the way down Chuck's ribs and flanks.
The other women watching from the wooden beds around them all widened their eyes, watching this scene either dumbfounded or with an infatuated expression.
After completing a full one hundred weighted push-ups, Chuck finally stopped, panting heavily. Sweat had already given his muscular body a statue-like gleam.
"Change positions."
He said in a low voice. Janet and Valentina finally woke up as if from a dream, getting off Chuck's back one after another.
Chuck stood up, looked around, and found a relatively flat spot. Then he bent his knees and squatted down until his heels almost left the ground. Only then did he spread his arms and raise his forearms, striking a pose that was both a horse stance and a muscle flex.
"You two, one on each side, sit on my shoulders and arms."
When it came to fitness, both Valentina and Janet were experienced. So from this pre-posed stance Chuck struck, they could understand his intention.
But precisely because of this, they felt shocked by Chuck's idea.
However, shock aside, the two women still stepped forward according to Chuck's request, lifted their legs, and sat on either side of Chuck's shoulders and the crooks of his arms just like that.
Soft and firm sensations came from his left and right shoulders. The unique female fragrance and sweat scent of the two women's buttocks wafted into Chuck's nose. Their thighs were tightly pressed against his biceps. They held Chuck's head with one hand and grabbed his raised forearms with the other, maintaining their balance.
Chuck felt the weight on both shoulders and nodded in satisfaction.
Although the sensations were different, and there was a slight difference in height between the two women—Valentina was firm and slender, while Janet was plump and mature, especially with the addition of a pair of massive breasts almost the size of a head and explosively fleshy fat buttocks—their weights were similar as he expected. Sitting on Chuck's shoulders like this, left and right, could be said to be almost perfectly balanced.
After push-ups came squats.
Chuck took a deep breath, let out a low shout, and explosively exerted force with his legs. As his bent knees gradually straightened, that statue-like muscular upper body steadily rose, carrying nearly 300 pounds of female weight on his shoulders.
His thigh muscles bulged high like rocks, every single muscle fiber almost clearly visible under the skin.
Having already had the experience of the push-ups just now, Janet's reaction this time was calmer. But with Chuck's repeated squatting movements, as well as the heavy panting sounds and the muscular sensation full of masculinity coming from under her buttocks, her pair of beautiful mature feet dangling in mid-air still curled up anxiously from time to time.
However, after doing more than ten like this, besides his legs feeling slightly warm, Chuck completely felt no fatigue at all. So he frowned slightly, realizing that Janet and Valentina's weight was suitable enough for doing push-ups, but if it were squats, it was still a bit light for his pair of Qilin (unicorn) legs.
"Yitong, you come over too."
Thinking this, Chuck squatted back down and called out in a low voice without turning his head. The beautiful mature mother, originally sitting side by side with her daughter on the edge of the bed, watching her beloved man's so strong figure, with spring water flowing wildly between her legs, blushed and got up in response, walking quickly in front of Chuck.
Chuck looked at Yitong, whose face was flushed with spring. Maintaining his original posture, he nodded and signaled her to come closer.
"Come here, wrap your arms around my neck and cross your legs around my waist."
There were already people on his left and right shoulders. To have her ride on his neck, not to mention there was no room to sit, it would also be very easy to fall off. So hanging her directly on his body like a human weighted backpack was the right solution.
"Mmh... okay."
Yitong answered, nodded gently, and took two steps forward again. Carrying a burst of milky female fragrance, her black long hair hanging down gently, she pressed her soft, smooth body against Chuck's chest from the front. Her soft jade arms wrapped around his neck, her massive snowy white breasts pressing against his sturdy chest. Then, according to Chuck's request, she slowly wrapped her plump, long, beautiful legs around his sturdy waist.
Just hanging directly on Chuck's body like this.
Inside the originally relatively cool artificial cave, the surrounding air gradually heated up amidst the body temperature of the four people overlapping each other. As sweat blended, it started to make people feel a bit breathless.
The additional female weight finally made Chuck's thighs feel a satisfying tension. So his legs exerted force again, and he started doing extremely standard squats carrying the weight of a full three women.
With every squat, his leg muscles tensed to the limit; with every rise, he lifted the tightly wrapped Yitong in front and the two women on his shoulders together. Yitong's plump female body and pitch-black long hair rose and fell gently with Chuck's movements. Her soft milky flesh rubbed repeatedly against his chest. Sweat almost formed a small puddle in that soft, fragrant cleavage. Occasionally separating briefly, the converging and accumulating sweat would flow down the bodies of the two.
However, after doing more than ten more squats, Chuck had just gotten into the zone, but Yitong was the first to run out of stamina instead.
Her gentle face was full of flush, her breathing gradually grew rapid, and the strength of her arms wrapped around Chuck's neck also became weaker and weaker. Her whole person was tottering, looking as if she was about to slip off. Finally, biting her lower lip lightly, she spoke in a panic while panting in a low voice.
"Hubby... I... I can't hold on anymore..."
Seeing this, Chuck had no choice but to stop his movements, letting Yitong get off him first. Then he frowned and pondered for a moment. His gaze inadvertently saw the large wet patch between her legs, and the corners of his lips curled up slowly.
Only then did he issue a command again.
"Then take off your slutty panties."
"Since you can't hold on, I'll help add a fulcrum between your legs."
He looked down, signaling with his eyes for Yitong to look at the slowly rising, towering tent between his legs. The latter immediately understood Chuck's meaning in a second, her beautiful face instantly burning bright red. And Janet and Valentina sitting on Chuck's shoulders, the former still pretending to be cold-faced while blushing, the latter looked down at her good friend, a thick interest emerging in her beautiful eyes.
"I know..."
As Chuck's capable helper and loyal bitch, Yitong unsurprisingly nodded submissively again. She reached down into her floral skirt and slowly took off a pair of soaked lace panties carrying a rich, hot mature female scent.
The wet, slippery fabric slipped from between her plump thighs, pulling out a trace of crystal-clear string. She raised her long, plump legs again, gently wrapping them around Chuck's muscular waist. One hand hooked around his neck, while the other reached down shyly yet firmly, pushing aside Chuck's pants, grasping the scorching, high-spirited giant dragon, and proactively aiming at her already wet area between her legs.
Then she raised her hand, firmly wrapping it around Chuck's neck again. Her beautiful face was covered in a red flush, pressing tightly against Chuck's chest. Raising her head, her red lips whispered softly in Chuck's ear.
"Hubby... it's okay now."
"Good!"
Chuck nodded in satisfaction. Then his legs explosively exerted force, carrying the weight of two mature women on his shoulders and the tightly wrapped Yitong in front, firmly and solidly straightening his body.
And at the moment his knees straightened and his waist and hips thrust straight again—
Squelch—
A wet, slippery, and muffled sound of penetration suddenly rang out. The scorching giant dragon, carrying astonishing power, instantly stretched open Yitong's already wet, plump garden. Unreservedly reaching the deepest part, it crashed fiercely against that soft, sensitive palace gate.
"...Mmh oh oh!!"
Yitong's gentle, beautiful face instantly tensed, her eyes widening sharply. Her red lips opened, but only let out an extremely light yet trembling muffled grunt. Her long, beautiful legs instinctively wrapped tightly around Chuck's strong waist. Her toes curled tightly in the air. Her whole person was like being nailed, pressing tightly against Chuck's chest. Warm, rich milk immediately spilled from the massive breasts pressed against Chuck's chest, flowing crazily along the skin where the two touched.
Chuck didn't pause at all, entering the workout state again.
With every squat he made, the giant dragon would appear from between Yitong's legs with a squelch. And with every rise he made, it would unreservedly disappear again with a squelch.
"Woo oh oh oh oh!"
Yitong couldn't hold it in anymore, raising her snowy white, beautiful neck and letting out a suppressed, sweet trembling moan. Her gentle face was full of flush and confusion, her plump waist trembling involuntarily. Her whole person was bounced up and down by Chuck's thrusts, like a broken doll used purely for venting.
A large amount of crystal-clear water stains continuously flowed down her plump inner thighs, drawing long silver strings in the sunlight filtering in from outside the cave. Janet, sitting on Chuck's left shoulder, watching this scene beneath her, her breathing also grew increasingly rapid, her mature voice carrying obvious desire.
"Baby... you playing like this... Mommy can't hold it in anymore either..."
Similarly, it wasn't just her. Valentina, sitting on Chuck's right shoulder, although still keeping a straight face, her green eyes stared intently at the lower bodies of the two pressed closely together, and her breathing also clearly grew heavy. And on the wooden bed behind the four of them, Julia, Jiang Qi, and the other women had long since started satisfying themselves with their hands due to unbearable itching in their hearts. For a time, sounds of water arose everywhere, and a sweet, musky smell spread.
Inside the cave, sweat, sweet juices, and strong female and male scents completely intertwined. After continuing for a period of time, Chuck finally completed a full one hundred weighted squats.
However, the natural testosterone-boosting effect brought by squats, as well as Yitong's slutty, charming appearance, also made him completely enter high-desire mode. So Chuck, who should have struck while the iron was hot and continued to the next movement, had no choice but to temporarily switch strength training to cardio. He just started a grand battle right there with the three people hanging on his body.
Half an hour later, the mature women trio were all defeated.
Thanks to the powerful buff of the yellow potion, even releasing three times consecutively, Chuck wouldn't feel the slightest bit tired, but actually felt a bit more refreshed. So he couldn't help but think, perhaps future workouts could all be carried out combining labor and rest in this "alternating workout and fucking" way...
But anyway, push-ups and squats were completed. Next, there was only the last movement left—pull-ups.
Carrying the three twitching, fainted mature women to the bed one by one, Chuck didn't bother to put on the clothes scattered on the ground. Bare-assed, he walked to the stone wall at the edge of the cave, raised his hands, and grabbed two slightly protruding rock parts overhead respectively.
Strictly speaking, these two rocks weren't actually "protruding," but just irregular marks unavoidably left by Chuck during the process of excavating the cave previously because of the low-strength bronze tools at that time. The grippable part was not even ninety degrees. Even a professional rock climber would find it very hard to grip these two points for a long time.
But Chuck is Chuck after all. After finding a good grip point, his forearms and hands instantly exerted force, and his whole body rose straight into mid-air just like that. He actually relied on pure grip strength to overcome these grip points that could be called extreme.
Chuck just did a few pull-ups up and down like this. Needless to say, this kind of training relying purely on his own body weight still had no effect.
So he straightened his arms, maintaining the hanging posture just like that, turned his head again, and looked at Julia and Jiang Qi behind him, who had long had peach hearts in their eyes and had been waiting for a long time.
"Stop looking, it's your turn to come help."
"Okay~~"
Julia and Jiang Qi responded in unison. They each quickly got up and trotted over, one left and one right, each hugging one of Chuck's two thick thighs, wrapping their bodies tightly onto them like koalas.
The sensation of muscle stretching appeared again. Chuck let out a low roar, the veins on his arms popping out, forcefully pulling himself and the weight of the two women up together. Until his chin passed the rock height, sweat slid down in large patches from his tensed arms, chest, and abs, flowing along his thighs onto Julia and Jiang Qi's bodies.
The two women's eyes were like water, having long entered a state of heat. Watching the high-spirited giant dragon swaying before their eyes, they actually hugged Chuck's waist in unison. While hanging on Chuck's thighs, they brought their small mouths close together.
Squelch, smack.
While doing pull-ups, Chuck enjoyed the oral service of the two women on the left and right.
Every time his arms exerted force, pulling himself and the weight of the two women up together, his broad latissimus dorsi and arms bulged high like rocks, the veins clearly bulging under his sweat-drenched skin. Sweat slid down in large patches from his tensed chest and abs, flowing all the way down his V-line, dripping onto the upturned faces of Julia and Jiang Qi, and then flowing into their mouths along their red lips and tips of their tongues.
"Squelch... tsk... squelch..."
The two women, one left and one right, licked the scorching dragon body simultaneously like two thirsty little beasts. Julia's blonde hair stuck messily to her sweat-drenched cheeks, her azure eyes watery. She focused on dealing with the left side, her fragrant tongue sometimes nimbly swirling around the tip, sometimes letting out wet, slippery, and bold sucking sounds. Jiang Qi, blushing, carefully yet greedily tasted the other side from the right. The soft tip of her tongue traced all the way up along the veins. Occasionally, when it touched Julia's fragrant tongue at the tip, she would retract it in shock and shyness, pulling out a thin silver string.
Chuck exerted force again to pull his body up. When his chin passed the rock height, it would be simultaneously taken in and squeezed by two wet, hot small mouths. That intense pleasure mixed with the soreness of stretched muscles made his every exertion even fiercer.
Doing pull-ups time and time again just like this, sweat continuously rolled off his firm abs, smashing onto the tips of the two women's noses and lips, and then impatiently licked into their mouths by them. Saliva and sweat slipped from between their lips, flicking out wet, shiny arcs in the air.
A long while later, as Chuck pulled his chin past the rock height for the last time, his arms suddenly exerted force to pull himself and the two women to the highest point together. All the muscles in his body tensed to the extreme, his body jerked violently twice, and accompanied by the sweat sprinkling down from his body, he instantly erupted, pouring directly all over Julia and Jiang Qi's bodies and faces.
Then Chuck straightened his legs, putting the two women back on the ground respectively, and only then finally let go and landed.
In the end, one hundred push-ups, one hundred squats, one hundred pull-ups.
Panting heavily, Chuck turned to look at the women behind him who were completely dazed. He wiped a handful of sweat from his face and revealed a meaningful smile.
"Training is over, next it's time to have a good, satisfying cardio session."
As his words fell, Julia pounced on him immediately, hanging on his body like an octopus. Her snowy white long legs skillfully wrapped around his waist, and her jade cave, already muddy like a swamp, directly opened its doors to him.
A wet, slippery sound of bodies colliding, charming pants, and low moans instantly rang out in the cave. Sweat, sweet juices, and milk completely intertwined.
Another feverish grand battle completely lost control and erupted in the already sultry stone cave...
...
In all fairness, Chuck believed he had already done his utmost in terms of humanity and duty towards the women in the north of the island.
So until they finally made the decision to all proactively submit together, Chuck actually didn't feel surprised.
What surprised him a bit was that, having experienced reinforcement from potion after potion, a flash of inspiration "weight-bearing" training conducted when there was nothing to do under the sudden extreme heat, actually caused him, whose body had already reached superhuman levels, to experience the phenomenon of "muscle soreness" when waking up the next day!
Chuck, who used to have basic workout experience, knew very well what this feeling meant. Even once upon a time, when he just started working out, what he liked most was this sore feeling.
Muscle soreness, in essence, is the result of the combined action of lactic acid accumulation and micro-damage to muscle fibers.
That "weight-bearing" training yesterday that could be called crazy—first carrying the weight of nearly 300 pounds of Valentina and Janet doing push-ups, then superimposing Yitong's body weight hanging on the front, doing squats with a weight load exceeding 400 pounds, and finally even bearing the weight of about 200 pounds of Julia and Jiang Qi to complete pull-ups.
Saitama's training method was nothing more than this.
And under such extreme load, Chuck's muscles underwent a massive amount of anaerobic metabolism, producing vast amounts of lactic acid. At the same time, the muscle fibers also experienced a large number of micro-tears, which was the source of this sore, swollen, and even slightly tingling feeling.
This couldn't be counted as an injury, but represented that the body was about to activate the overcompensation recovery mechanism, mobilizing nutrients, growth factors, and repair cells to repair the damaged muscle fibers, ultimately making the muscles become stronger!
In other words—this long-absent sore feeling actually proved that that absurd harem weight-bearing training yesterday could still improve his current potion-reinforced body through the most primitive workout method!
Of course, the specific improvement effect probably couldn't be displayed through data anymore, but there was one thing Chuck understood.
All along, the various potions he took, their improvement effects on various abilities, were all manifested as "percentage" data...
Currently, Chuck's physical stats bonus was 170%, and this bonus margin was based on his original physical stats.
Thinking of this, lying on the bed, a burst of intense excitement flashed in Chuck's eyes.
If it went as he expected, his physical stats could truly be improved through this primitive workout method. Then the ultimately improved attribute bonus, would probably be different from the potion's bonus... not continuing to increase the percentage, but directly increasing the base value!
In other words, the improvements obtained by these two methods were likely not in the same multiplier block!
There was simply no better news than this.
Even though he had already explored most of the areas of this deserted island, besides the tiger, there were still more powerful existences blocking his advance. And similarly, even though he defeated the tiger, that narrow escape experience, even the current Chuck didn't want to experience it again.
Originally only being able to become stronger by refining potions and developing technology actually made Chuck feel a bit lost in his heart for a time. After all, the flowers of the other shore on this island are limited, and the hearts of fierce beasts are also limited. After eating a portion of potion, until the next time he killed a fierce beast, Chuck could only rack his brains to improve from the aspects of weapons, equipment, and combat skills.
But looking at it now, he could still become stronger...
At least he would become stronger than he is now!
Feeling the bursts of soreness and swelling coming from all the muscles in his body, Chuck not only didn't feel the slightest pain, but instead curled up the corners of his mouth, gradually clenching his fists.
Until he killed all the fierce beasts on this island, occupied every piece of territory as his own, and became the true King of the Deserted Island, he would not stop pursuing this strength.
