The moment Stacy went into motion, Tsuruko immediately let out a pleasured groan as she squeezed the dickgirl's shaft with her inner walls. With every plunge made into her back door, her moans continued, exhaling hot and ragged with every motion, eagerly awaiting the climax sure to come. Between that pleasure and the soreness she felt, locked in the full nelson position, Tsuruko was no doubt in masochistic bliss, her eyes occasionally glazing over every couple of seconds before the next instinctive blink brought her sights back into relative focus. She could've lost control if she wanted to, but she held back, and for good reason: she wanted to keep her eyes on Tora as he sat and watched the show.
Tora remained in place, keeping his eyes squared on Stacy and Tsuruko and not pulling his gaze away for so much as a second. He occasionally blinked, sure, but only to keep them from straining. He tried to keep a serious face, but the arousal he felt watching his maid get butt-fucked by their mutual lover made it hard to resist getting hard, even inside the constraints of his cage. Likewise, it was hard to resist any show of weakness, but even so, he pursed his lips, occasionally biting the lower one, and stifled his grunts of mild yet aroused discomfort. It might not have been to the degree that Stacy was hoping for, but he hoped, subconsciously, that she was pleased with the end result.
At Stacy's praises, Tsuruko nodded in gratitude, and again in compliance to the suggestion that followed. In that time, she worked herself up to speaking, something she was lacking in the motivation to do in favor of the cries of pleasure she was letting out instead. But now she had the opportunity, and she complied, not wanting to let her mistress down.
"Oh yeah, it feels so fucking good! Your thick bitchbreaker cock in my slutty ass... Hnng~! It can't be beat!" She played it up just a little, but overall, she spoke the truth. After glancing back at Stacy for a moment, she looked right at Tora, startling him to attention. "I bet you're enjoying this just as much as I am, aren't you, Master?" She let out another moan, which then morphed into a haughty laugh. "Then again, I wonder how much you can enjoy it, while you're locked away on the sidelines like a total cuck! You aren't getting fucked, you aren't doing any fucking yourself... Hell, you can't even jack it to the sight of Mistress blowing my ass out like this! So it's clear which one of us is enjoying this more!" She let out another laugh, which in complement to earlier morphed into another moan.
Tora looked down and blushed brightly as Tsuruko dressed him down while in no position to do so. It was like a switch of her caliber to play the domme and the sub at the same time. But what he was more curious about was how Stacy would respond to what Tsuruko managed to bust out.
