The Muscle-Mat Addendum

Basara shivered with excitement and arousal, his ferociously erection twitching and leaking his pre-cum liberally. It was all he could do as Mio obeyed Toin and got down on all fours over his lower half, her generous breasts with hardened nipples pressing into his abdomen. Being a good muscle-mat meant not moving at all once you were spread out on your back. He was exceedingly fortunate that the pillow under his head was stout enough that he had the angle to watch Mio and Toin rather than simply stare at the ceiling.

He was so turned on right now. It was hard to believe it. This moment was the combination of many of his deepest sexual fantasies and it was difficult to accept that he was worthy of such.

Certainly he would not be if he let his lusts distract him from his duty. He tore his gaze from watching Mio's beautiful face, twinged with nervousness and expectation as Toin got into position behind her, to take in what he could of the room. A threat to her life was unlikely in public with so many in rapt attention but it could not be discounted. Thankfully, Maria could provide overwatch (provided the mischievous Succubus wasn't letting her own libido go wild) and his Cursed blade could be summoned into hand with but an act of will.

But soon enough his attention was drawn back to Mio as Toin was true to his word and penetrated her fully in one long stroke, causing her body to stiffen as she cried out. She was soon rocking and pressing down upon him rhythmically, her large breasts compressed and squashed out between them as Toin drove into her again and again. She crooned about how big Dong-sama was-how it was too big and Basara felt his balls pulse and ache as he imagined Toin's enormous member filling her, expanding her far past his own lesser shape.

It was not long at all before Mio was shrieking in bliss, no longer caring at all about her audience and certainly not the sex-aide beneath her with its smaller dick squirting out pre-cum as it was smashed and pressed to the side underneath her. The eroticism of the moment was intoxicating for Basara. The members of the Hero Clan were warriors all and as such he was sure that most if not at all had experienced the sensual bliss of being used as a mere muscle-mat while another couple made love atop of them, but he had not, perhaps because he'd been driven out so early in his maturity. He had little doubt that any one of them would greatly wish to be in his shoes today!

"Alright girl! Let's do the prone-bone!" declared Toin gaily and Mio squawked with alarm as her back-half was manhandled by him, her legs pulled out so that she collapsed even more fully upon Basara. Her sweaty mammaries were dragged atop his torso as she was pulled down a bit so that her chin rested between his pectoral muscles. Her arms wrapped around him for all intents and purposes just like a body-pillow which he was quite aroused to imagine was exactly what she thought of him at the moment. A picture popped into his head of a pillow with his image on it and a small pink dildo attached to it and he wished he could cum intensely. To be used like this by a man with a superior manhood was his personal fantasy, the only thing hotter was remembering when Toin rutted Ryoko back in the school bathroom while he and Takeshi watched impotently with rock-hard erections.

Mio's eyes were wide and there was a deep red blush across her cheeks and nose, her mouth hung open as Toin thrust into her rapidly and powerfully. Her big rounded butt looked absolutely beautiful as Toin's abdomen slammed into it over and over again sending each fleshy cheek jiggling and rotating wildly. Then Mio's hands were clutching Basara's shoulder blades hard as Toin suddenly withdrew a large amount and held himself up as if to build anticipation for his next thrust. Basara stared at the soda-can thick pillar sticking out from between the cleft in her rear, marveling at seeing more than his own length outside her and yet instinctively knowing that some more of that mammoth prick was still inside her.

Then he was slamming it back in fully and leaning down over her to ask, "You like it, Mio-chan? Tell me!"

"Ah! Yes! Amazing... your dick is... R-reaching so DEEP inside..." she sighed and closed her eyes as Toin kept his pelvis glued to her and rotated his hips and she continued after a moan, "It feel so good....YOUR DICK FEELS SO GOOD!"

Toin laughed and brushed at his chest with his fingernails in a gesture of confidence, "Yea-yea. It is pretty great." He seemed to be taking a breather, remaining with his full length inside of her. Mio rested her cheek on Basara's chest seemingly rather exhausted and thankful for Toin's thoughtfulness even as she gently shifted her hips and made small sounds of pleasure at the feel of his bulk inside of her. Soon enough she was squeaking as Toin's attention went to her bottom and both of his hands grasped her cheeks and pulled them apart, "Ah. Such a pretty little asshole! Hey Basara, you got around to fucking this yet?"

He didn't answer obviously.

"Huh? You going to answer me or what, man?"

With her face so close, he could see a look of confusion on Mio's face but it was the leader of the discipline committee, the one currently acting as photographer after Maria had been punished, who spoke up, "It can't talk, Toin-san. It's a muscle-mat- just a thing until you allow it to ejaculate."

"Okay, that is fucking hilarious. How'd that even happen? Okay. You tell me, Mio-chan. Has uh IT ever fucked your butt?"

"Ummm....no."

"Awe, that's disappointing, man! Girls have three holes and every single one of them is made for milking cocks in each their own special way! Don't you know that! Well whatever. We'll take care of this right now!"

It was difficult for Basara to breath but not impossible as Kotegawa-san laid atop his face. That the seemingly strait-laced girl cared not at all that her rather generously proportioned bosom was pressed against his cheeks was a turn-on, underlining how she thought of him as simply an object rather than a sexual being. He was also feeling aroused because Mio had gotten up and was standing over him releasing his member from the sweaty prison of her body pressed against him. With his legs spread, his genitals were entirely exposed, his shaft sticking straight up bobbing and twitching in the cool air. He knew that Dong-sama was somewhere nearby and that in this moment he looked small and he loved it.

He felt a hand grasp his member and based on the size of it, he judged it was Toin's. Then he felt an ultra tight vice-like grip as Mio's hot chute slowly engulfed his tip. He was somewhat uncomfortably aware that her back-passage had recently been lubricated by saliva and sperm of a boy he did not know, even more so because he apparently had a small member that did very little to set off Basara's secret cuckold fetish. Still, one did not dishonor Toin-san by disobeying so he could not truly hold it against the person. Though Basara had to wonder why Kotegawa-san could not have used the same sexual lubricant she'd carefully applied to his own shaft. All such thoughts were abruptly pushed from his mind as Mio buried his entire length within her bottom.

Soon enough she was fucking her ass upon his shaft wildly, performing rapid squats atop him with admirable endurance for a girl who did very little physical training. He was proud of her for working so hard to honor Toin and he was exceedingly glad that he would not cum as a muscle-mat and could not disappoint him as that other boy had. For long minutes, Basara let his mind relax and his thoughts dissipate as he focused on the intense and even **** sensations coming from his genitals, practically becoming little more than the object he was trying to be, something to be acted upon and little else.

Finally, Toin signaled that it was time for him to rejoin the tryst and the discipline chief got up as Mio shifted walking back with her hands, his prick shifting inside her butt as she leaned back over him, her long flowing hair obscuring his face and sight. When Toin entered her, Basara noticed the change in pressure almost immediately. He could feel the membrane against his cock bloating with the passage of Dong-sama. He knew when Toin had fully seated within her because not only did the pressure increase intensely but he felt the boy's scrotum come in contact with his, filling the space between his legs to such a degree that he felt testicles against both of his inner thighs despite that he was fully spread eagle underneath Mio.

Then Toin and Mio were kissing like lovers and Basara's balls tightened and the tip of his member spat out a little pre into her rectum. He wanted to cum so bad. He cared about Mio, even probably loved her. He knew that Toin had no such feelings for her. How could he? He barely knew her. To Toin she was a tight wet pussy and a fine set of breasts. Another notch on his endless bedpost of sexual conquests. This knowledge made the moment all the sweeter, fueling Basara's fetish at the possibility of Toin stealing Mio from him.

"Damn! This feels better than I thought! You're so tight with a dick in your butt!" enthused Toin.

Mio was completely gone with passion as she cried, ""Meee too! I've never felt it so deep inside me before!"

"That's because Basara has a little fucking dick compared to me!"

Hearing that scathing comment lit a fire in him and he could not stop himself from bucking his hips and thrusting his member deeper into Mio's ass, the urge to cum was so overwhelming.

Basara was in absolute heaven. He was totally gone. Now would be the perfect time for an assassin to strike as he was completely incapable of thinking about anything other than the pleasure. Toin was the driving **** of this tryst, powerfully slamming his immense member into Mio over and over again, drawing out incredible loud moans and wails as she writhed atop Basara as he remained still and experienced the incredible sensations of her back passage squeezing and sliding around his prick in time with the other boy's thrusts.

When Toin finally came with a shout, his big balls slapped against Mio and Basara both as only the tip of Basara's shaft was still in her rear she was lifted so high as the other boy pounded out his orgasm deep into her climaxing quim. Mio's arousal that had been leaking out onto Basara's shaft was now joined by copious amounts of Toin's thickly flowing stuff and Basara felt his mouth water and he suddenly wanted nothing more than for Toin to release him so that he could suck every ounce of semen from Mio's well-fucked pussy.
