Punish both (original concept by "monkey17", proofread by me)

"I've herd enough. Both of you, follow me." You lead the two girls back to your office.

"I don't know what you're arguing about, but it doesn't matter. You two are out of class, so as far as I'm concerned you two are both in the wrong." The two girls look down at their feet in shame. "Since you're out of class anyway, you can serve your punishment now instead of after school." Both girls nodded, relieved they don't have to stay after school. You start their punishment by having them both strip naked. Kim is fitter, with a flat tummy but smaller chest (around C cup) and a much smaller ass. Even though Peggy is on the slightly chubby side, you can tell she is the more naturally curvy one with larger tits (around DD) and a fat bubble butt. To teach them to respect each other, you have them make out while fingering each other's cunts. It turns out that Peggy is the one more willing to comply, while Kim is a little hesitant. While they seem lost in the act, you go to the storage room and return with a large, flesh-coloured double-dildo. "OK, you two, you're going to fuck this cock together. The first to cum loses and will have to eat out the other girl while she sucks my cock." They both nod and get on all fours facing away from each other. You slide the dildo first into Kim and then into Peggy. "Right, we will begin once you two work the cock so far in that your asses touch." It takes a surprisingly small amount of time for them to complete your order. You have them hold it for a few seconds before having them begin. Your office is filled with the sounds of moans and grunts . Quite soon, you start stroking your cock slowly, enjoying the sight.

"Yes, you sluts, fuck that cock! Keep going!" You moan out.

In the end, it is Kim who cums first. "Arrr fuck, I'm gonna - arr I'm gonna cum!" With that, she sprays cum all over the floor, followed almost instantly by Peggy, who has a far less violent orgasm. "Kim, since you made the most mess, you're the one who is going to lick my floor clean. Now get to it." You smile as you watch Kim begin lapping up the pool of cum from the tiled floor. Once done, you have Peggy crawl to you and begin giving you a blowjob, wile Kim gets behind her and sticks her face in Peggy's cunt. The blowjob you get isn't the best you've had, but the vibrations from Peggy's moans as she enjoys Kim eat her out help. At one point, you grab Peggy's head and **** her down your cock and begin roughly face fucking her. After that, it isn't too long before you release your seed, shooting cum into Penny's stomach. You even hear her slightly **** and cough a little cum up once you release her. Once you're done, you have the two girls get dressed and get out, fully aware that Peggy's hasn't had another orgasm and is probably know **** to cum again.
