Yes, with an interruption

I continued to slide my raging hard cock in and out of her dripping pussy. I looked at the two of us fucking in the mirror. I glanced at her face, contorted in pleasure, then her breasts, swaying from the pounding I was giving her. I was soaring through the heights of ecstasy when I the door swung open abruptly and I was brought crashing back down to earth. Oh my god,Lauren forgot to lock the door!

"Well, well, what have we here?" interrogated the stranger as he closed the door. He stood before us, a vulture eyeing fresh carrion, his weary yet muscular frame jutting into the room, towering over us. He was aging, graying hair, but well built, as if he had performed manual labor his entire life. Lauren and I, coming to from our sexual fantasy, responded naturally: I pulled out from her loins and both of us attempted to
daintily cover our exposed areas with our hands.

"Look," he said after a short pause, "I won't be tellin' nobody 'bout this long's the little lady here does me a favor."

"W-w-what do you want?" Lauren stammered. Suddenly, the little seductress wasn't in control of the situation anymore.

"Jest suck me off a bit, that's all I'm askin'. Now, let's get started..." another pause as he unzipped his fly and locked the door behind him. "Well, boy, put yer cock back in 'er, don't jest stand there with yer hands over yer boner."

She positioned herself across the counter, so her legs faced one end and her head the other. I stood behind her, nervous about continuing, embarassed because I had never had sex with anymore than one otherperson at a time, especially not a complete stranger of a man who would be engaging in the act simultaneously. My firm, aching dick began to deflate slightly because of his presence. I realized she had already gone to work on him, his soft member hardening as she licked and sucked it like a lollipop. Watching her please the intruder made me go softer as he grew harder. She had offered herself to me, she was mine!

Then, however, I glanced at Lauren's inviting haunches positioned right in front of me, her dripping wet pussy staring me right in the face. No, she was too hot and I was too horny for this to happen -- as I took my now semi-erect dick in my hand and touched the head against her swollen lips, it stiffened as hard as ever and I slipped it back into her.

She began letting out muffled groans as she got pounded on both ends: she had been gently licking and sucking the stranger, but now he was nearly fucking her mouth and I increased my speed, wildly bucking inside her.

She spit him out: "Let's change positions, this counter is a bit rough on me." I pulled out and she sat me down on the toilet, sat down on me, taking my erection in and resuming the suck job on the stranger. I reached around and played with her clit, much to her delight as the muffled moaning increased. Before long, she began moaning heavily and whispered to me: "I'm cumming."

Her pussy contracted around my cock as she came and guttural moans seeped out muffled by the stranger's member. These contractions became closer together, stimulating my own cock beyond the point of no return. I tried to hold back because I didn't want to cum inside her, but the stimulation from her orgasm sent me over the top and there was nothing I could do. An incredible amount of pleasurable pressure built up in the base of my cock and then shot its way up through the shaft. I began moaning as I spurted into Lauren's writhing pussy. The pleasure was incredible and I kept shooting more and more, even after I would have normally been done. My dick grew softer and softer until it was limp and slipped out of her pussy. Just then, the stranger moaned and unloaded into her mouth. I saw his dick convulse each time his cum squirted down her throat. His dick became limp and slipped from her mouth -- we were all spent for now.
