Only a little

When the rod strikes, the resilient brunette lets out a pitiful yowl of anguish and hunches her shoulders instinctively to protect her sensitive boobs, but doesn't reach forward to cup them with her hands as a less determined girl might. She's actually impressing you with her fortitude, so you decide to give her another chance.

"Shoulders back, tits out," you order, sharply.

"Yes, Professor. Sorry, Professor," the young woman blubbers, offering up her nipples once more.

"I will repeat that stroke and if you flinch again, I'll add another six," you continue, tapping her swelling nubs so that she's in no doubt where these extras will fall if she earns them.

"Thank-you, Professor," you think she says through her tears. "Please may I receive the thirty-sixth stroke again."

You lash the cane down even harder this time, but the fit young student manages to hold still, despite the obvious pain, mouth open wide in a silent scream, until she draws breath and gabbles out her thanks.

The next couple of strokes go back to being only moderately hard, raising pretty weals on the upper slopes of her breasts, already drenched with tears, but when you flick a horizontal blow across her nipples for number thirty-nine, she shrieks, before quieting almost immediately.

"Not so loud, please," you request and receive another apology. Since she didn't actually move out of position, you again settle for a repeat rather than extras and she somehow takes this fourth cut to her tender aureoles without any further transgressions, but she's sobbing so vigorously that it's getting hard to aim. Accordingly, you decide it's time to change targets for the last nine and order Anthea to lie on the chair with her hips supported by the back and her head hanging off the seat. The obedient girl complies as quickly as she's able, considering how sore she is, then awaits further instructions.

"Now spread your legs wide."

Perhaps she expected this. Either way, she immediately does as required, achieving a full splits at a perfect height for beating, which is exactly what you do. Three strokes to her left inner thigh leave her weeping inconsolably. Three to her right make her retch from the excruciating pain. Three upon her plump pudenda send shockwaves through her inexperienced body, but still she thanks you earnestly for the thrashing you've given her.

At least, you think that's what she's saying, but she's crying so hard you can't be completely sure.

It takes about twenty minutes to get both girls sorted out, dressed, with dried eyes and somewhat poorer after tipping you generously. You opt for cash over sex, because you get so many opportunities to be pleasured by stunningly beautiful women nowadays that you usually prefer money. That's something you'd have believed impossible when you started using the Rulebook, but definitely not an unwelcome development.

When the students are ready to leave, you tell Anthea you'll see her next week and Lorna that you hope she'll never need to visit you again, which is her fervent wish also. The pair of erstwhile strangers hobble out, supporting each other side by side and you reflect how fortunate you are that your new position as Junior Dean gives you the opportunity to exercise your penchant for severe spankings without being excessively harsh to the other young ladies you discipline.
