We walked to a nearby brewpub for lunch and conversation. We discussed a few angles on my schoolgirl suggestion and decided to play that theme when we returned to Mary’s abode. I waited in the small room that served as Mary’s home office while the women browsed Mary’s closet for outfits. They were gone for what seemed like an eternity but eventually they emerged and made the wait well worth it.

Both were attired in classic school girl outfits - skirts that fell mid-thigh and button front shirts. I had them stand while I sat on the corner of the desk and scolded, “You two were caught cheating in math class and I’m sure know the punishment for violating the school honor code?”

“Yes, sir,” they replied in unison, looking at my paddle that lay on the desktop.

“What is the penalty?” I asked.

Both were quiet for a moment, but then Mary murmured, “A paddling, sir.”

“Indeed,” I replied. “You’re both going to get a long spanking culminating with a dozen hard swats of the paddle. Who wants to go first?” Julie timidly raised her hand. I take a seat in a chair and beckon her to my right side and guide her over my lap. I lift the back of her skirt and begin to pull down her panties. She lifts her hips slightly to aid the process. I look over at Mary, “You might as well remove yours now, too.” Mary doffs her own panties and sets them on the desk. I begin to spank Julie bare bottom and continue at a brisk pace of hard swats until her cheeks are rosy and glowing. Mary takes her place and a few minutes later, her bottom is colored and heated just like her friend’s.

“Ok, stand side-by-side and bend over with your hands on your knees,” I order, picking up the paddle. “You’re each due a dozen swats.”

“Sir,” Julie interrupts, “Our bottoms are already so very sore. Can we offer something else for a reduction in our punishment?”

I pretend to ponder the options, “I have an alternative that would reduce the number by half - just six swats.”

“What is that alternative, sir,” Mary asks with a sly smile, certainly knowing my intent.

“You two kneel and give your headmaster a blowjob and then each of you will own only six swats,” I announce.

The two hurriedly kneel before me and Julie opens my pants. They take turns stroking and sucking until I declare, “I’m about ready to cum. Better not waste a drop.” Mary takes the first two spurts in her mouth and then Julie directs my cock toward her open maw and captures the remnants. Both swallow conspicuously and then assume the position. I look at their pink asses and tap the paddle against Julie’s proffered bottom. “Maybe, I should have suggested that the headmaster fuck naughty girls doggy-style,” I quip and give her a hard swat.

“The day’s still young. We should try that next,” Julie groaned.
