Let her take two

You consider Grace's offer with interest, there is something about the way her ass wiggles that make you wonder if she is even getting off on the stimulation. Is that why she wants more? A look at the younger sister brings another thought to your mind. You don't want to let her go just yet, there is something about the power you have over this innocent redhead that's acting as an opioid. You can hardly critique Grace for getting excited by her punishment when you too are definitely aroused by administering the blows.

"You can take two of hers." You announce after the few seconds of deliberation. The whimper you hear from Sally could be one of relief, terror or protest but in spite of your best intentions your erection stiffens a little at the sound. "It will be OK, Miss Mathewson." You tell her as you instruct her to return to the position with her forearms on the desk.

"Yes, Sir." Her always quiet voice, is huskier than ever, but she sounds resolved to accept whatever you decide. The two blows are not as hard as the previous four, but Sally gives those little squeals of pain that you find so difficult to ignore; after the last one you let her pull up her shorts and send her to sit on the couch. This time when you try to pass the paddle to Mr. Carter, he catches you adjusting the bulge in your pants.

"These two are still yours Dean Hawkfeather." He points to where Grace is squirming against the desk. "Please, be my guest." And so two more times you whack the dark wooden paddle against the raised ass of a student, the way Grace moans with each blow again makes you wonder if this wild-redhead wants to be disciplined like this.

You are both relieved and amused to see Mr. Carter is also effected by the nature of the punishment, his erection while perhaps not as obvious as yours, is clearly visible by the time he finishes administering the last of the sister's punishment.

"Girls, you may go." You dismiss the sisters who walk awkwardly out of your office both rubbing the backs of their shorts without any shame. You watch with a bit of envy wondering what those firm, young buttocks might feel like now that they have been warmed by your blows. "Mr. Carter, a word if you please."
