Not long.

"Oh, I see I'm not the only one who is going to be having sexy fun times with you today!" Shizuka cooed as she closed the door behind her, being the first to recover.

Tsukane breathed a sigh of relief. Kurumu's strip show had made him momentarily forget that Shizuka was already under his sway, and had her slutty kitten mode active. "No, no you are not. I hope you're ready to have some fun today."

"Oh yes, most definitely!" she nodded fervently, her tail out and wagging. Tsukane refrained from making a comment about how he was just about to tell her to go full Neko, but that was redundant now. He didn't know if his entry would hold her back from retaliation. "How do you want to start?" she purred.

"First, Kurumu, how about you strip her naked too?" Tsukane asked his succubus slave girl.

"Right away Master!" Kurumu agreed immediately, walking up to Shizuka, who obligingly raised her arms. Kurumu grabbed her shirt and pulled it up over her head before tossing it aside, while using her tail to expertly unclip Shizuka's bra and pulling it off.

While she was doing that, she bent down and undid the Neko teacher's jeans skirt, and pulled it down, her tail following suit to grab her panties, and make them follow. Shizuka stepped out of them, as well as her shoes and socks, maintaining her adorable smile all the while. "Well, you've got me naked now!" she said cheerfully.

"Yep... Now what to do with you next?" Tsukane mused.
