Victoria lay face down on the mat, panting and groaning.

“Y’know, one of these days you might actually beat me in a fight,” Samantha teased. Victoria sensed her looming over her. “But today is not that day!”

Victoria grinned. “Fight’s not over yet...”

She placed her hands flat on the mat and began to push herself up - but there was a sudden weight pressing on her back. She froze, a ripple of arousal emanating through her body, as she was forced back down onto the mat, unable to resist - her arms were abruptly devoid of all strength.

“You think so?” Samantha giggled.

Victoria managed to turn her head to one side, leaving half her face pressed against the mat, but otherwise she couldn’t move. The weight felt like an anchor holding down her entire body, though it only occupied a small space on her back. Her muscular arms and legs now felt like noodles, splayed out uselessly around her. Her ample boobs were squished beneath her. In her peripheral vision, she could see her girlfriend towering over her.

A part of her wanted to struggle, to try to escape from beneath the unstoppable force bearing down on her. But she knew there was no point. And besides, she knew what the weight was - and she didn’t really want to escape. Her heart was pounding faster and faster; her nipples were hardening; her pussy was growing warmer and slicker by the second...

She felt the weight shift along her back, reaching her side, and then beginning to turn her over. She felt herself roll sideways, onto her back. The weight was suddenly gone, but a moment later it was pressed onto her belly instead. And now she could see it. Small, pale, and delicate. And completely irresistible.

Samantha stared down at her, looking jubilant. “You did ask me to step on you,” she cackled.

Unable to verbalise an answer just yet, Victoria instead let out a moan. “Uhhhh... ihh... is... is this a truh... trigger?”

“Maybe,” Samantha smirked. “Or maybe you’re just a total slut for my feet... All I have to do is press down on you a little bit, and you’re reduced to a quivering, whimpering mess...”

As if on cue, Victoria let out a whimper. A trickle of drool dribbled from the corner of her mouth as Samantha slid her foot up her body, between her tits and onto her chest.

“So, what d’you think, Vicky? Do you want me to keep you under my foot, under my power, helpless and horny, with a drooly mouth and a drooly pussy? Or should I release you, so we can carry on the fight?”

“Don’t you dare,” Vicky whispered.

Samantha raised an eyebrow. “Don’t I dare... what? Keep you trapped? Do you want me to let you up?”

“Nooo... Please don’t let me up... Fuck, I’m so wet...”

“Say I beat your ass. Say it, or I’ll let you go...”

“You - you beat my ass,” she spluttered frantically. “You beat my ass...”

“I’m the champion, and you’re weak and feeble. Say it.”

“You’re the champion! I’m w-weak and feeble!”

“I’m your all-powerful Mistress, and you’re my helpless foot bitch.”

Vicky smiled, eyes almost rolling with pleasure as she gazed up at Samantha. “You’re my all-powerful Mistress,” she sighed. “And I’m your helpless foot bitch.”

With a wolfish grin, Samantha started to slide her foot along again, moving it onto Vicky’s neck, and then lifted her foot, keeping her heel pressed down. She wrapped her foot around Vicky’s chin, and then continued to shift it upwards until her toes reached Vicky’s lips, covering them and holding them closed. Those toes... They were so small, yet the idea of opening her mouth with them resting on top seemed utterly impossible.

Vicky made a muffled grunt. Her fingers spasmed. She wanted to touch herself so badly, but all the bones in her arms seemed to have vanished.

The last thing she saw, before she closed her eyes to try to endure the tidal wave of arousal, was her girlfriend’s wicked smile.
