Muscle Girl Yumi: Taro's Counterattack!?

A little Yumi to brigthen your day! It's crazy that after this, she still has a couple more nuggets of story to do (really short ones), as well as a couple of full-blown short stories written by fans of Kinsyo's that Kinsyo drew some fan-illustrations for (the boxing one and the massive back shot). I've been avoiding those/saving those for last since they're legitimately quite long lol. In the meanwhile, please enjoy!

-----------------------------------------------------------

 

Yumi doesn’t always force herself on Taro. There are times where she lets him call the shots as well.

“Here, go right ahead, Taro-nii♪” Yumi said as she plopped onto her back, her legs and arms akimbo. Although Taro had gotten quite used to seeing massively muscled girls around him all the time, seeing his cousin, who was not even in middle school yet, and her spectacular muscular development was still quite the shock for him.

“You can try whatever moves you want on me~ Just don’t hurt me too badly, ‘kay~?” said Yumi from her relaxed, outstretched position on the ground. Her muscles had lost any extra pump they may have had prior to now, but their sheer mass, even in a relaxed state, was utterly mind-blowing. Taro, at a complete loss as to what kind of moves he could possibly pull off against such a titanic physique, merely stared down at Yumi’s colossal body, dumb stricken.

“…Or we could just skip to my turn again?” Yumi spoke as she peered from beyond the wall of her mammoth pecs, which pulsed as if they could explode even larger at any moment.

Taro made up his mind. There was only one move he could think to do at a time like this!

“Hi-yaaaah!”

Taro clasped onto Yumi’s left arm, and skillfully pulled it into a cross armbar!...Except for that Yumi’s body was so ridiculously thick that his legs couldn’t properly reach across her chest. Her upper arm was so overblown with muscle that rather than to say he had it locked between his thighs, it was more accurate to say he looked like a sloth hanging from a tree branch; the attempt to lock her arm at the elbow completely undermined by his inability to create any leverage.

Nevertheless, Taro continued his assault on Yumi’s joints with fervor!

“Nnnghghghh~~~!!” grunted Taro, his groaning increasing as he tugged on Yumi’s left forearm with every ounce of his entire bodyweight and strength that he could muster.

“Oh? Ohh!? I think it’s working~♪” Yumi cheered, sounding pleased.

“Hrrnnggh~!!!”

Taro continued to pull with all his might, the tremors of all of his exertion coursing throughout Yumi’s body, causing her soft and relaxed muscles to jiggle slightly.

Even for one as terrifyingly muscular and powerful as Yumi, if her joints are properly locked down, then the hold should indeed be effective. However, even with all of his strength and weight behind his hold, even with Yumi’s relaxed muscles trembling slightly, Taro’s armbar was little more than a slight discomfort to Yumi.

It didn’t take long before Taro, struggling valiantly to keep his cousin subdued, rapidly started to feel a bit pained himself; the more powerfully he tugged on Yumi’s forearm, the more Yumi’s mountainous upper arm began to bear down on his lower body. Usually, the person performing the armbar would be able to use the upper arm and body of their opponent as a leverage point while they pull on the forearm to lock the elbow, but Yumi’s upper arm was too thick for Taro to wrap his short, gangly legs around, meaning that the only force he could apply was the downward one on her forearm. Consequently, this meant that more than locking Yumi’s elbow, Taro was mainly just applying pressure onto his own body.

Despite the mounting pain of his own hold recoiling on him, Taro staunchly refused to let Yumi have yet another win, and so continued to try to lock her arm.

“Nngh~!! Gotcha now, huh~!?”
“…Hey, is it my turn yet?” Yumi asked nonchalantly as Taro poured every fiber of his being into his futile hold.

“If you don’t give up soon, you could end up with a broken arm…Grrahh!”

In the face of Taro’s bluff, Yumi began her counter-offensive.

Yumi used her monstrous strength to wrest her arm from Taro’s clutches in an instant!….or not. Instead, she decided to maintain her position as it was, and pour power into her left arm. With this, no matter if he tried to use his strength or his weight, Taro was now completely immobilized under her beefy arm. Taking things even further, Yumi poured even more power into her arm, causing it to thicken suddenly, as if it had a life of its own. With just these two simple actions, the pressure on Taro’s lower body increased exponentially. In other words, Yumi merely made it so that her massive arm would not budge from the position Taro once had it locked in a single millimeter, and was now crushing Taro’s body underneath it.

“Whatcha gonna do now, Taro-nii~? Wanna be my armrest for the rest of the day~?♪”

“Yu…Yumi-cha….un…uncle! I give up…h….help…it hurts…”

And just like that, Taro was effortlessly done in by Yumi using his own hold against him.
