Change room fun

Once they had a decent number of items gathered up, Bill and Morgan strolled over to the store's changing room. Tucked into a corner, it had a curtain blocking curious eyes from spying on changing customers.

Morgan entered alone, and the curtain closed with Bill right outside. A minute or two later, the curtain parted slightly, giving Bill a clear view of Morgan's slutty red matching set of bra and panties.

From my vantage point, I could only see glimpses, but it was enough to make me stare uncontrollably, burning with lust and jealous as Bill reached through the curtains to "feel the fabric" as he put it (an action consisting of him openly groping Morgan's tits).

The curtain closed, and Morgan began to change again. This time, Bill decided not to wait, stepping right through the curtains and giving me a brief but clear view of Morgan in the middle of changing bras.

The curtains closed, and I realized I could sneak close now without either of them outside to spot me. I moved to just outside the change room, and listened in.

Immediately, I could hear the sounds of clothes rustling and wild kissing. In my head, I could see Bill peeling the lingerie off of Morgan while their tongues wrestled, and I couldn't stop myself from rubbing at my erect little cock through my pants.

After several more seconds, I heard Morgan hiss in a breathless whisper. "Let me put on another pair, asshole. We can make out any time!"

Bill only laughed in reply, and though I heard Morgan sliding into another outfit, the sounds of the two of them making out never stopped for long.

Over the next few minutes, Morgan went through at least a dozen changes of clothing, with Bill all over her the whole time, and my covert groin-rubbing was bringing me close to cumming in my pants.

I'd heard Bill pressuring Morgan more and more insistently to help him get off over the course of the encounter, and realized by the light thump of knees on the ground that my girlfriend had just decided to listen to his pestering.

"Just remember, you're paying for all these clothes." Morgan laughed as she unbuckled Bill's pants, the lowering of his zipper followed by the unmistakable sound of Morgan's lips wrapping around the head of Bill's cock.

I had to strain to keep from breathing too loudly as I listened, and realized that I was going to end up jizzing in my pants at any moment...

Just then, my eye caught sight of the store's female clerk, who despite not having a view of my lower body, was looking at me suspiciously. I panicked, hustling out of the store as she gave me a cold, suspicious look. I guessed that I'd been about three seconds away from mall security - or the cops - being called on me...

I found a bench near to the store and took a seat where I'd be able to see Morgan and Bill leaving. I had to hunch over to hide the small tent that just wouldn't fade, knowing that Morgan was at this very moment sucking Bill's cock in a public change room...

Eventually, Bill and Morgan came strolling out of the store as if nothing unusual had happened, a few bags with them, undoubtedly full of slutty underclothes...

Despite my close call earlier, I couldn't stop myself from sneaking along after them, with Bill soon getting pulled along by Morgan into a shoe store.
