The treadmill exercise makes Peko sweat

Of course, being the Ultimate Swordswoman meant having plenty of stamina. A treadmill wasn't going to defeat Peko Pekoyama, even if some cat managed to. With her shirt still riding up to the point where only her nipples and the upper sides were covered, she stepped onto the treadmill. Nekomaru rushed over, not wanting to give her an excuse to look down. "I'll handle the controls! Yeah... this one's programmed to match your speed for the Ultimate workout! We've got a lot of Ultimate technicians and similar guys in the school here, so don't underestimate this workout! If you beat this, then you're gonna bump all those technicians back down to the reserve course!! But even I can't beat my personal setting! Well... One time I thought I was going to, but then-!"

Peko groaned. "You shit yourself... right?"

Nekomaru yelled wildly, while backing up slightly. "HOW DID YOU KNOOOOW?!"

The swordswoman swore under her breath again and began to match the speed of the treadmill as it moved beneath her. For the students watching, it was an absolute treat. Those long legs moving up and down in motion... the hips, switching sides over and over, while the students imagined her thong riding the curve of her ass underneath her bloomers... and most of all, her tremendous, swinging breasts, which moved as if they had their own busted jiggle physics programming. it was an inspiring workout, to be sure.

Just as Peko was beginning to underestimate the machine, she felt the speed and incline increase. It now reminded her of her training for the young master, where she'd run up mountain-tops every day. That is to say: it was rather challenging. She adjusted her stance and now began to move her legs at superhuman speeds... the speed of a ninja, or, perhaps more appropriately, an assassin.

"Gahahaha! She's really good! Watch closely, boooys!!" Nekomaru cheered. He'd actually gotten so caught up in the workout aspect he was barely noticing her body any more. The other students were just the opposite. "But everybody has a breaking point where they give up and shit themselves! This machine's gonna find that breaking point, mark my words!"

Peko clenched her teeth at the annoying exercise she'd been given. Suddenly, it felt like she was being asked to run up a sheer wall at amazing speed. The other students, who'd been sitting, now stood to get a better look as the ramp began to block their view from the front. The view was... amazing. Peko's shorts had ridden up her ass so that they were practically a thong themselves. Sweat was pouring from her body now. Her glasses bounced up and down erotically on her flushed face. Sweat even stained that white t-shirt she was wearing... through it, they saw the shape of her large, pink nipples, pressing against her shirt. One student took out his phone and began recording for posterity.

She ought to be concerned about that, but she wasn't even watching it. All she could imagine was the hypothetical scenario, the same she had during her training so long ago: what if the young master was at the top of this mountain, being held hostage by a rival gang? Would she spare any speed? Would she sit down and rest? No! She'd defy the odds, increase speed, and reach the top to save him! This mountain wasn't going to beat her. She threw her head back, nearly squeezing her eyes shut, her teeth bared in an expression of murderous intent.

"THIS IS INTEEENSE! I'M GONNA SHIT MYSEEELF!" Nekomaru applauded, sending sparks flying as he clapped his massive hands together. "You're not the Ultimate Swordswoman for nothing!! I can't imagine a thing on this planet that could kill yaaaa! And to think, you're doing it all barefoot! Gahahaha!"

Peko didn't respond, she just ran harder and harder. The treadmill machine was beginning to emit sparks and smoke itself, as it continued to try to adjust the program, but found itself at its limit. It hadn't been built to be exceeded!
