just barely

Naruko had to bite her lip to hold on. she understood this was a lesson in control but wasn't it a bit much for a first lesson. she had bitten her lip so hard it was starting to bleed and she felt the last of her resistance crumble.

she was on the verge of giving in when Madam whispered in her ear. "go ahead and cum." not needing any more prompting Naruko stopped holding back and had a massive orgasm. she opened her mouth to pant as only madam sexy kept her on her feet.

"take a few deep breaths and relax," said Madam sexy. Naruko did as she was told and was soon standing by her own power. "that was not bad but you will need to be able to handle even more and last a lot longer than that. I only let you because I knew you were about to break."

"thank you sensei," Naruko said.

"while you are training under me call me mistress," said Madam sexy.

"yes mistress," said Naruko.
