What is Minseo's suggestion?

Minseo will take Natalie's place

"I don't think she can handle another twenty-odd strokes, Professor," she says, looking up at you. "I think I'd better take that dozen after all."

You smile in relief. Reducing the total by two dozen will leave two more, plus a repeat and, say, another one for losing position. Natalie ought to be able to survive that many at least and putting a few welts on Minseo's backside should be fun.

Natalie forces herself back to her feet and apologizes for her transgression. You tell her what to expect and then begin.

When you repeat the stroke to her side just above the hip, you think she's going to collapse again, but she somehow holds on and you have Minseo swap sides so that you can administer the final three as backhand strikes to the ribs. Natalie bears these better, although she's clearly having trouble breathing, thanking you in a wheezing rasp.

Minseo helps her back into her top and then asks whether she has anything to say to her.
