A challenge

A loud slap with lingering sting across the front of your thighs wakes you. Evidently, the chains released your legs, dumping you on the floor. Some cuffs remain, locking each wrist to an ankle, but there is nothing keeping your arms behind your back.

Before you can blink the sleep from your eyes, a hatch opens beneath you, and you tumble into a small pit. The fall is only a few feet, yet enough to make you let out a surprised "eep." Now thoroughly awake, you watch as shutters roll over the top of your cramped cylinder. Only thin slits offer glimpses of the above room.

"You have learned to properly please individual genitalia," your mechanical trainer tells you, "but in your new life you must be able to serve multiple genitals while keeping your master a priority. This test will challenge you to satisfy them as quickly as possible with some conditions. Every minute another cock will be added to the queue." A quick look around your tiny dungeon reveals many possible glory holes between the soft lines of light. "You have permission to swallow as many of their gifts as you like," the voice continues, "it is expected you will be hungry." You drop your jaw and moisten your pussy in preparation for an onslaught of dildos. "One more rule: Your cunt is reserved for your master's cock." Well that's disappointing. "If another cock touches that hole, you will receive a corrective shock. Preform satisfactory or you will be punished with an indeterminate amount of orgasm denial." The machine does not provide guidelines for what constitutes satisfactory.

With the explanation finished, your challenge begins. The first dildo to pop out of the wall is human. You raise your hand (and the foot cuffed to it) to start stroking the phallus. A Trikod modelled pecker appears behind you, but it's easy to reach the long noodle with your other hand.

Twisted somewhat awkwardly and jerking two very life like dildos, you wait for the next penis. A minute later, a Gavleth monster enters near the top of your sex pit.

Not wanting to **** on the sausage and knowing it won't fit in your anus, you let go of the Trikod dick and reach for the Gavleth one. Trikod are know for expelling a fair amount of water when they cum, so you lie on your back to suck it, hoping to drink the water required for a fuck session like this. That's what you tell yourself anyways. On your back, Cuffed limbs in the air (one leg stretched the other bent) to jerk the other cocks, you wrap your lips around the abandoned Trikod member.

Aware the sextoys need to cum in a timely manner if you are ever to escape, you start jerking the human one faster. It blows a surprisingly realistic load onto your chest. When the human cock disappears back into the wall, you take the growing Gavleth one in both hands. The sticky, human goo smells so real you wonder if it is. After all, the Syndicate has extensive milking facilities.

Further encouraged that the Trikod might dispense watery cum, you **** the fully erect yet still wobbly shaft deeper into your mouth. Gagging around the head, you tongue one if its many expulsion ports. In the back of your mind, you feel a strange desire to be a slutty as possible, so you **** the noodle down your throat. Muscles spasm and tears water in your eyes as your reflexes try to cough the intruder out. In seconds, you are slurping down the tangy liquid.

The Trikod cock slips back into the wall, and at the same time, a Gabber one pokes out near the bottom of your round chamber. After catching your breath, You sit up and move your left hand to the smaller of the two members in your sex cylinder. Aroused by the larger, Gavleth one, you start licking its tip.

Another cock appears below the Gavleth simulacrum. More interested in the shaft your tongue is circling, you keep your mouth and hand on it. The newest member of your dildo gangbang isn't completely neglected, however. You intentionally rub it with your tit while you kiss up and down the girthy Gavleth dick until the monster member is satisfied.

With a rumbling spasm, a jet of sperm erupts from the large cock. Bouncing off the opposite side of your chamber to splatter onto you. The satisfied dildo slides away, and you briefly devote your mouth and free hand to the most recent cock. The tapered shaft is of an alien you aren't familiar with, but its natural ribbing feels good in your mouth. You rub it against the inside of your cheek until a Bantam vulva enters your sex pit. Enticed by its savory lubricant, your tongue eagerly laps the purple pocket pussy.

So focused on the dripping pussy, you hardly notice the spray of Gabber spunk. Its penis disappears soon after. As does the unknown cock when twirling it over your nipple proves to be enough to blow its oily load. A Varrus cock complete with three testicles pokes into your cramped dungeon. Delicately rolling the triplet of jewels between your fingers makes them swell with semen. You keep slurping the flavorful Bantam cunt mostly ignoring the new genitals that invade until you quench your thirst with its high pressure squirtings.

The Varrus is next; it shoots a massive load across your thighs. A fruity smell and a few tentative licks reveal you like the taste of the sweet alien jism, so you roll over on your knees to suck your breakfast off your leg and the floor while grinding your ass against another cock. Inevitably you taste some of the other cum slowly intermixing on the floor as your tongue laps greedily. The other genitals have left a fair amount of liquid on the floor, and as you pleasure more, the bottom of the of your fuck pit becomes covered in alien semen.

Getting the variety of sextoys to cum quickly proves a challenging task. Multitasking is the only way you'll meet the goal, so you contort to please the genitals in creative ways. Twisting around the micro-dungeon, trying to satisfy the dildos as quickly as possible is difficult to say the least especially with the cuffs on. Often, you raise a leg or spread both of them to jack off the many cocks that stick into your bukkake dungeon.

The myriad of sextoys aren't much help. While very life like, they're completely mindless. When the **** box decides it's time for you to be spit roast by a Lintoan, you have to guide its primary member by hand. The bulbous shaft resembles anal beads, so it's your anus is the only logical hole. There isn't enough space in your small prison for proper doggy style, but you get close by bending your knees under you and stretching one hand back to finger an Oo'lick pussy that recently appeared. Neck bent awkwardly, face pressed against the cum slick walls, you manage to take the Lintoan's secondary cock in your mouth. The spongy shaft does occasionally pop free of your lips, but robotic version of that unsual alien race is able to rhythmically pound both your ends until its synchronized satisfaction.

As the machine warned, your pussy is only for gas bag penises. In a moment of lust filled weakness, you raise your ass high in the air to let your needy cunt engulf a meaty member, but a nasty shock radiating out from the shaft ruins your hopes for a quick orgasm.

Soon after, you find out the no-dicks zone extends around you empty pussy. It happens while you were taking on of a Turnk's double-dick up your ass. When the un-buggered cock got too close to your pussy, a painful arc struck it and lancing shocks pierced your stretched anus.

While you are left frustrated, cum fills your rear sex hole and dribbles out to join the ever rising puddle around your knees. The multi-species swirl is a few inches deep when you finally get a Gas Bag cock peaks into your chamber. **** for anything in your pussy, you let go of the penises you were sucking and stroking. Kneeling, arms pulled back, you mash your greedy cunt onto the round penis, grinding against it until it rubs your clit. Your hard nipples collect cum from the wall while you squelch your pussy lips around your relief. The wonderful release fills your body and you splash back into the increasingly deep cum pool, gasping.

"Rest has not been approved," squawks the training voice before the last wisps of your orgasm have left. "Your current performance is already inadequate for the expectations of your master and the standards of the Syndicate. Failure to improve will result in extensive disciplinary measures."

Threatened, you get back to work, unsure if you can succeed. There is no clock or way to tell the number of dicks remaining, but if the training voice scolded you, you must not be doing very well. The true scope of your problem dawns on you. There are rarely more than three cocks at a time in your chamber, and if it takes a few minutes of stroking, licking or tit-grinding to make them cum, simple math means you're buggered. Not in a fun way either.
