You try your best to.

"Arbok, I have never done this before, and while I will try my best, I am sorry if I dissapoint you." You tentatively reach out a hand and lightly trace a finger up one of his cocks. It twitches slightly at your touch. It was warm, though not unpleasantly hot. Smooth though, and tapered up at the tip. You grab up at the top and slowly work your hand down the left shaft. Reaching out with your other hand you grab the right cock and beging alternating you hands, while one hand pumped up the cock, the other pumped down. Arbok let his tongue flick out every now and then, clearly enjoying your ministrations on him.

"Does that feel good?" You ask quietly, showing your nerves as you jacked off your first cock. Correction, you first two cocks. Or would it be your first pair of cocks. Anyway, your attention is brought back as he nods in pleasure at your actions.

"Arrrrbok."

Suddenly you feel a slight push on your head. Looking behind you, you see arbok's tail lightly pushing your head closer to his pair of dicks.

"Alright, alright. Give me a minute to get warmed up. I'm just nerveous is all. I have never done anything like this." Arbok blinked in sympathy and the light pushing vanished. You draw your head near, and take a small lick alongside the tip of one of the cocks. The taste wasn't bad as you might think. It wasn't anything to brag about but it wasn't exactly horrible. If you had to describe it, maybe slightly sour, but not in a bad way. Leaning forward a bit more, you take the tip of the cock into your mouth. Sucking in, you let your tongue glide across the tip, taking a second to flick at the little hole on top. You are rewarded as a small dallop of precum dribbles out into your mouth. A small amount also escapes out the other penis and runs down your hand, providing a bit of lube to your handiwork.

You slowly begin pressing your mouth deeper onto the dull red shaft. You feel a tickle at the back of your throat and pull back slightly. Barely 3 inches are in your mouth, and you have only taken just the tip. If you had to hazard a guess, you would say that the pair of cocks are at least a foot long, if not 13 inches or so. Though at the base of each cock was a knot, around 5 inches thick. You let out a shudder at the thought of the cock spearing in and out of your pussy.

"Maybe not that fast though. I'm still new to this after all." The thought run ls through you as you begin bobbing your head up and down. You have continued pumping up and down both of arbok's cocks while you suckle at one of his tips. Taking a deep breath through your nose as you push a little bit deeper onto the cock. The tip brushing the back of your throat. Due to your current angle it would be unlikely you wpuld be able to take it deeper. Bringing your head back up, you stop jerking arbok off just long enough to prop yourself up onto your elbos and knees. From this angle you are looking down onto the pair of dicks, rather than looking up. You resume your hands jerking arbok off, and switch your mouth to the other dick. You start off by licking from the base all the way to the tip, with your hand trailing close behind it.

You grin as you see a shudder run through arbok from his head to his tail. You can feel the vibrations run through both of his dicks. Suddenly you feel something tickling inbetweem the folds of your pussy. Turning your head, ypu see arbok's tail teasing the entrance to your pussy. Clearly he wanted to reward your excellant service. As you begin suckling the tip of his cock again, you can feel his tail slightly penetrating your pussy. Only a couple of inches or so. Just enough begin teasing you. You take your mouth off of his cock and were about to scold him for teasing when he withdraws his tail from your pussy. Already, your pussy was wet and throbbing slightly from his teases. You realize he must think you are also teasing him since technically you have only sucked the tip of his dicks so far. Going on a hunch you place the tip of his cock back in your mouth and flick the tip with you tongue a few times. You feel his tail return and begin flicking ever so slightly back and forth across your walls. Whatever I did to his cocks, he would do to my pussy. Clever little bastard. You take a deep breath and angle yourself so your throat is a straight shot at you can make it. You begin sliding his cock deeper and deeper into your mouth. Shortly after it touching the back of your mouth however your gag reflex kicks in. Wincing as your throat convulses, you feel arbok's tail penetrate a bit more deeply into you. You feel his tail splitting you apart, touching parts you thst had never been touched before.

"Mmmhmm fcccmmkkhh." You garble out a moan as you speed up your hands pumping up and down the shafts. Trying again you continue to flick and twist your tongue across the underside of throbbing cock inside your mouth. This time you manage to get 4 or 5 inches down before your gag reflex starts. This gag was just a bad as before. It **** you to back up, and at least take a breath.

"Mmm do you like me sucking these cocks. I bet you were overjoyed when you got caught. You just couldn't wait to get my lips wrapped around your twin cocks." Holding the hemipenes together you take both of the tips into your mouth. You can only fit an inch or two before your teeth start grazing on the cocks, and you take that as your cue to stop.

"Arrr! Arbok!" Arbok was sighing contentedly as your hands continued to work over his shafts. Your hands flying along thanks to the spit and precum lubing up the cocks. Arbok's tail was still slowly moving in and out of you. The constant pleasure had started the beginnings of another orgasm.

You let the pair of dicks go and select one. You grab it by the base, your hand grabbing the thick knot at the bottom. You begin bobbing your head up and down, fighting the gag reflex everytime you take the dick too far down. You are too horny too care though at this point. Arbok's tail has left you on the edge of another orgasm and you are deternined to make him cum. Your other hand is now flying up and down his other cock. You can feel each shaft throbbing and twitching now. You know it won't be long before he unloads into you.

"Arbookk!!!" You feel him writhe under you, his tail spearing deep into your cunt as he cums. The **** of his tail piercing you forces you to take his cock further. You have probably just slightly over half of his cock in your mouth when you feel it pulse and white cum shoots out of the cock you were jerking off. String after string of cum lands on you as arbok continues to climax. You can feel him cumming Down your throat as you gag and convulse around his cock. You barely notice however as you have already fallen into your second orgasm. You pull back your mouth, gasping for fresh air and coughing as you try to clear the cum from your throat. Arbok is laying down on the bed, panting as he winds down from his own orgasm.

"How did I do?" Im sure I was covered into his cum, and as I got up to go the bathroom all I could hear from him was a contented sigh.

"Arrrbok."
