"Chastity belts have male versions as well. If Milady doesn't wish to use one, let's have Young Master Haruta wear one."

Natsuya was once again rendered speechless.

She imagined various scenes from hearing this, causing her face to become even redder.

"N… no! That's no good as well!"

"Why's that?"

"No reason! No need to do anything unnecessary. I… we won't do anything like that, so no need to worry, Mai nee-san."

Mai glanced at Natsuya for quite a while.

"Alright… I believe in Milady and Young Master Haruta." The maid flashed a gentle smile.

As for whether or not something was concealed behind her smile, only she herself would know.
