“When did you get that outfit?"

“Last night." She jerked a thumb out the door and nonchalantly replied,

“I raided Beverly's secret stash."

My boner was now quite confused, and my mouth gaped open.

“You're joking, right?"

She didn't answer save for a mischievous smirk while walking into my closet to pull her graduation cap and gown off its hanger. Her smirk broadened as she took my graduation cap and gown off its hanger as well and tossed the items to me. I merely caught them and continued to gawk while my uber-hot Head Girlfriend finished putting on her graduation gown. And only after the cheap polyester in our school's main color covered up that fire engine red ensemble did I finally close my gaping pie hole and stand up to get dressed.

Belle came over to join us for the drive to school. We students were assembling early, and by agreement the seven BIC girls and I rendezvoused at our usual lunch table one last time before walking together to the school's basketball court where all of the graduating seniors were being sequestered in preparation for our last march as a group. Our parents would be heading to the football field and its bleachers where the ceremony itself was being held. The way the girls tittered and giggled and kept sneaking glances at me, I wondered if they ALL had gone without regular clothing underneath their gowns. So with that idea in my head, I sidled up behind Naimh and casually wrapped my arm around her waist. And when she Leaned into me for a sideways hug and a quick peck on the Lips, I let my hand drape down so

I could cup her ass through the gown's fabric

The horny little minx wasn't even startled. The hot redhead just pressed herself even tighter into me and then shoved her tongue in my mouth, nevermind that we were all trapped in fairly close quarters with the entire senior class.

And no, she definitely wasn't wearing pants or shorts or anything beneath her gown. Hell, from the feel of her ass in my palm, I thought she might be wearing a thong.

Maybe...

Of course, after THAT first kiss, all six of the other girls wanted a quick makeout session with me (nevermind that we were still all trapped in fairly close quarters with the entire senior class). On the other hand, we were the BTC. Nobody paid us much attention anymore.

And no, apparently none of THEM were wearing anything more than lingerie underneath their gowns either.

My eyes were still pretty big after Alice went last in getting a pre-ceremony makeout session, and I muttered, "You all realize we're meeting up with our parents after this, right?”

“What? We're wearing our gowns," Naimh reasoned. "It's not Like anyone else is gonna grab our arses to check what we're wearing underneath."

I steamed just a little and glared at Sam. "I thought we agreed on keeping things relatively low-key in front of the parentals, not risking complete discovery."

Sam shrugged.

“What? Every set of parents knows you're fucking us by now. Now maybe there are only a few who know you're fucking ALL of us, but even if somebody figures out we're going commando underneath our gowns--"

“Wearing just your underwear isn't ‘going commando'," I sighed while rubbing my forehead.

“Whatever. We're a bunch of girls having harmless fun on our Graduation

Day. Or are you saying you're NOT looking forward to the after-party when we stand in a row and unzip these gowns at the same time?"

"You're right. You're right." I held up my hands.

“I surrender. I surrender. I just really hope we don't get caught.”

Thankfully, we didn't get caught.

We did, however, socialize with everyone's families. After the ceremony, the parents all came down onto the field to congratulate and hug their children. I had to force myself to remember to breathe knowing I was about to interact with the parents of all SEVEN of my girlfriends back-to-back-to-back (to-back-to-back-to... you get the idea).
