Jack

I was in the middle of a particularly heated session with Mark. Sucking his thick cock like it was my favorite lollipop while the chat went wild with dirty talk and requests for more. I had just taken him all the way down to the base - gagging slightly as he hit the back of my throat - when I heard the bedroom door creak open. Panic flooded through me instantly.

My heart pounding in my chest as I turned to see who had caught us in such a compromising position. But instead of screaming or crying or any of the other things I expected, Jack just stood there... Watching us with an expression that was almost impossible to read.

"Jack..." I gasped around Mark's dick - trying desperately to pull away and cover myself up at the same time. "I can explain..."

But he held up a hand to silence me - his eyes never leaving mine even as Mark continued thrusting into my mouth behind him.

"You don't need to say anything," he said quietly. "I already know everything."

My mind raced as I tried to process his words... Wondering how long he had been watching and what exactly he knew about my little webcam operation. But before I could form a coherent thought, he shocked me even further by speaking again.

"Just keep going," he said - his voice steady and calm despite the bombshell he had just dropped. "I want to watch you finish him off. For old times' sake."* I stared at him in disbelief.

A million questions bubbling up inside me but no way to voice any of them with Mark's cock still lodged firmly down my throat. In the end, all I could do was nod mutely and turn back to the task at hand - determined not to let this unexpected interruption derail my show.

So I sucked him harder...

Pumping my fist along his shaft in time with each bob of my head while Jack looked on from the sidelines. It was surreal in a way...

Knowing that my boyfriend was watching me service another man like a cheap whore... But at the same time, it only served to turn me on even more. Pretty soon, I was moaning and slurping around Mark's dick with renewed vigor - putting on an even better show for both him and the audience.

When he finally came Pumping load after load of hot cum straight down my throat while Jack watched impassively from across the room. I swallowed every last drop greedily - milking him dry with lips and tongue until there was nothing left.

Only then did I pull away...

Turning to face Jack fully as Mark slipped out of the frame behind me. We stared at each other for a long moment - neither one of us quite sure what to say or do next.
