It's just a dream, it's just a dream. I kept telling myself that in order to try and convince myself that I wasn't really witnessing the scene that was unfolding before my eyes. It's just a dream - or maybe it's a nightmare. I wasn't quite sure.

Cassidy had just been casually masturbating on top of my bed. Reluctantly bound to the chair in the corner of the bedroom, I could do nothing more than watch. I was also quite vulnerable, because I had been ordered to get fully naked to match her. The exposed nature of pussy had probably revealed that - despite my best efforts to suppress it - I was actually fairly aroused by watching the beautiful young redhead pleasure herself. If that had been the extent of this intimate experience, I might've allowed myself to go with it - but there was another person involved.

My husband.

As if on cue, Cassidy called out to him, "Come here, stud - my mouth is hungry for your cock."

+++++++

That whole scene had been set up because Cassidy had caught me screwing her boyfriend. Actually, she hadn't really caught me, but - in my unrestrained state of delirious arousal - I had simply blurted out that truth while on the phone with her. In retribution, she said the only way I could escape her informing my husband about my first-ever full-blown affair was to actually give her unprecedented access to him... while I sat there watching the two of them.

That indecent proposal had been a very awkward conversation to initiate with my husband. It helped that Cassidy and I had already tag-teamed sucking his cock (twice), but still...

"I want to try something," was how I had first brought it up my husband. "I know I've never been into role-playing in the bedroom or anything like that, but I have an idea for you to consider."

As my husband listened intently, I had then described the details of the scene that Cassidy had arranged; that I'd be gagged and tied up naked in the corner, that she'd be naked on our bed, and that he'd then enter the room to 69 with her... while I sat there unable to interrupt or even object.

"Really?! Why would you want to do that?" my husband had asked.

I would never have proposed such an arrangement if Cassidy hadn't demanded it, so I had to lie, "Oh I dunno, I guess I'm just curious to watch you without being the one on the receiving end."

His follow-up question was equally difficult for me to answer, "Umm, okay... but why will you be naked too?"

I shrugged. "It'll make everyone more comfortable if no one has their clothes on."

+++++++

As soon as Cassidy had called out to him, my husband - who had been watching her masturbate from the privacy of the hallway - strolled into the room. The size of his erection shocked me... although I'm not sure why. Had I assumed that he wouldn't be so turned on by another woman? I found myself incredibly jealous and angry... until I remembered my own infidelities. I didn't have a self-righteous leg to stand on, but it was still hard to watch my husband climb onto our bed with this beautiful temptress.

I watched as he started planting kisses all over her bare skin. She immediately grabbed his cock and started tugging on it, while slowly coaxing him to get it closer to her mouth. She had just about finished that process when my husband suddenly said, "You know what? My wife never gets on top to 69 with me. Would you be willing to do that?"

He said that almost as if I wasn't in the room, and Cassidy eagerly reacted in the same way: "Fuck her! Oh, FUCK yes! I love being on top!"

I was pissed. They didn't care. My husband laid down on his back, and Cassidy immediately crawled on top of him, inserted his cock into her mouth, and lowered her pussy into my husband's waiting mouth.

I was angry and curious and bitter and aroused and confused and horny all at the same time. I didn't know what to watch: my husband's cock sliding in between Cassidy's kissable lips; the rhythmic movements of her smooth young body as she rocked her hips into my husband's face; or my husband's tongue, eagerly lapping up the forbidden nectar of another woman.

The louder they moaned, the faster my heart raced; the more dramatically they moved, the more rapid my breathing became. Animalistic urges took over, and I desperately tried to rub my bare pussy against the seat cushion, hoping for a mere sliver of self-gratification. I was caught up in the moment, and enjoying the view... until Cassidy unexpectedly escalated the situation.

She pulled off my husband and pleaded breathlessly, "Fuck... I can't help it, I want to ride you so bad. I need you in my pussy."

As she started to reposition herself, my husband glanced at me and raised a concern, "Wait - was that part of the deal?"

Her response was callous, "If she got to fuck my boyfriend, then I get to fuck you."

My objections were muffled by my gag. My husband looked understandably shocked, "Wait... what??"

Cassidy continued carelessly revealing my secret, "Oh - what your wife didn't tell you was that she actually screwed Steven a few days ago. In your own house, no less."

My husband glared at me, "Is that true?!"

I couldn't answer, so I just closed my eyes in silent guilt.

It was quiet for a moment... until my husband spoke again, "Well, then, Cassidy, I will very happily fuck your fucking brains out while my wife sits there and watches. I've been dying to cum inside your pussy ever since I met you."

I opened my eyes just in time to see Cassidy's eyebrows shoot up, "Oh FUCK YES, daddy, then fuck me hard!"
