Punish Sabrina

"I didn't see you nod, so this man is going to punish me," you whisper into Sabrina's ear. Sabrina shudders and lets out a pleading, "Please, no" but you slap her and she quickly silences and then repeats what you've said.

Katherine turns her head to the side, trying to ignore what she's heard, but you are going to make sure she hears her sister.

You stuff a gag back into Sabrina's mouth so she doesn't make too much noise. You grab a ruler from your desk and position Sabrina over you lap in the spanking position. You bring the ruler down, hard, on her porcelain skin. Sabrina yelps in pain, her scream muffled by the gag but easily heard by Katherine. A red mark quickly blooms on Sabrina's cheeks.

You bring the ruler down again, and again, and again. Sabrina screams at the pain and tries to wriggle away but you hold her over your lap, making sure Katherine can hear her sister's struggles. Again, and then again. Soon, Sabrina's cheeks are bright red from the punishment.
