Quite well.

"Very nice," Sylvain grinned at Hilda as she finally fully stripped.

"Th-thanks," she hesitantly replied, blushing as she resumed work.

Sylvain smirked as an idea came to mind. "Hey, stick your ass out, would you?"

"Um, why?" she asked, even as she obliged, leaning forward to press out her ass. SMACK! Hilda yelped as Sylvain gave it a smack. "S-Sylvain!" she protested, although to her surprise, she found herself sticking her ass out more, shaking it slightly, as if inviting him to do it again.

"What? You could just refuse," he teased, giving her another spank.

Hilda tried, she really did, but she couldn't resist the desire to do as Sylvain asked, or even voice any real protest. So she helplessly let him spank her a few more times, before he let her continue on with assisting him with cleaning. 'At least he has the decently to do some of this himself,' she mentally huffed as they organized his dorm.

...

Soon enough, they finished up, and Hilda sighed in relief. "Glad that's finally over! Now to get dressed and head back to my dorm..."

"Oh, actually..." Sylvain grinned, making Hilda pause. "Why don't you sit in the bed while I return the cleaning supplies and wait for me to come back?"

Against her better judgement, Hilda said, "Alright..." Still naked, she sat down on his bed as he left, her heart beating frantically. She should want to leave, but she didn't. She couldn't even bring herself to try. So in a mixture of apprehension, and anticipation, she waited.

Soon enough, Sylvain was back, and grinned down at Hilda. "Now then..." he smirked.
