They have hit her metaphorical Achilles Heel.

Kushina hasn't felt like this in a long time. Not since Minato got her pregnant with her child all those years ago. Even back then he had never managed to get her horny to the point that it hurt like this, because he was rather plain in his tastes for sex where she wanted to do more intense things on the regular like she had with Mikoto before she married. Between the jutsu smoke she inhaled, the teasing of her whole body, and her pussy being eating out and fingered to the point where she would have come long ago, the wild side that she had held back for so many years raising a child came roaring back to the forefront. "OKAY OKAY, PLEASE STOP I'LL GO TO THE MASTER JUST PROMISE HE'LL MAKE ME CUM, PLEASE!!!!!" She cries out between her moans and shrieks.

All three pause in their actions, letting Kushina catch her breath, they adjust so that the grip they had on her loosened up. In an action that catches Kushina off guard, they all give her a group hug. Tensing in surprise and whimpering slightly while still in the throes of her lust, she relaxes into them as each one of them kisses her gently in strong contrast to the intensity of the earlier kisses. "I'm sorry we had to do that Kushina, but actions like yours have consequences." Mio says with a voice of silk. "Don't worry," Kei adds, "The master will treat you well and give you everything you need and want." Reina and Kei help Kushina stand up on shaky legs as Mio stands getting her top back on. "It's alright and know from now on you don't need to think anymore, just obey." Reina says with the gentlest look that Kushina had ever seen on the tanned girl. Taking her hands Kei and Reina lead Kushina to the hidden door that Mio opened up, the door that will bring her to the mysterious master they spoke of. With her pussy twitching and thoughts focused solely on how good cumming would feel, she did not resist walking on shaky legs through the door.
