Chapter 12
What do you do next?
Get on your knees and start sucking.
You can't stop thinking about Sia's giant cock, especially what it tastes like. How it would feel in your mouth and how far you can take it inside you. There's only one way to find out. You turn around to face Sia and slump down to your knees. Her cock is already hard and ready to go. You can somewhat make out its dimensions in the darkness, but its true length is unknown to you unless you feel it up. Sia places a hand on top of your head and starts running her fingers through your hair.
She says, in her hushed voice "Go ahead. Take it. It won't bite."
You're still a bit nervous, but you follow up with her words. You wrap your hands around the girth of her shaft and notice that your hand doesn't even fit all the way around it. She's really big, and you can feel heat emanating from her dick that quickly warms up your hands. You can also feel it throb in your hands as blood rushes through the shaft, keeping her erection afloat.
You take it one step further and bring your hands over to her tip. As you touch it, you hear a quiet moan come from Sia. Her cockhead is absolutely covered in a sticky substance, most likely precum. You want to taste it. You bring your head closer to her cock and stick out your tongue. As your tongue connects to the hot and tender flesh of Sia's cock tip, shivers run through your body. You start swirling your tongue around her head and lapping up all of the precum that you can. As soon as it enters your mouth, you quickly swallow it, enjoying the sweet yet bitter taste. After a while of doing this, you notice that her precum is coming out non stop, so there's really no way to get all of it. You give up on that endeavor and move on.
You move your head even closer and bring Sia's member into your mouth. You close your lips over her tip and start ever so slightly bobbing your head.
Sia let's out a slightly louder moan and says "Oh yeah baby, just like that. Take your time, we're in no rush. I can't wait to hear you gag on my shaft!"
Your jaw is already open wide, so taking in the rest of her will certainly be a challenge. Your tongue dances around her sensitive tip, still gathering up her ever-flowing precum and making Sia pick up her breathing. You begin to slide slightly further and further down Sia's shaft, covering more and more of it with your spit. You slowly pull yourself off of her dick to take a little rest, and then it's back to sucking. Soon enough, your straight up blowing Sia's dick, taking a good few inches of her in your mouth. You bring your hands over the remaining length of her shaft and start stroking her at the same time. You realize that you are not even close to taking half of her shaft in your mouth, but you enjoy sucking her off nonetheless.
After a few minutes of the blowjob, Sia speaks up "Hey, don't you think you can take it a little bit deeper? For my sake."
You take her cock out of your mouth for a second and say "I would love to, but it's way too big!"
Sia responds "Oh don't worry, I'll help you along the way. Trust me, it'll feel better for the both of us."
You don't want to disappoint Sia, so you agree to her offer.
She says "OK, now let go of my cock and just leave your pretty little mouth on it."
You take your hands off of her girthy cock and move them to your sides. Sia gently takes your head in her hands and starts pulling you ever so slightly further down her member. You feel every bump and vein of her penis cross your lips and enter your mouth. Soon enough, her tip reaches the back of your throat and lathers it with precum. Sia lets out another moan and stops. You want to gag, but you manage to control yourself. She pulls you slightly off of her cock and back down again, shoving her tip slightly deeper down your throat. This time, you can't help but gag around her dick.
Sia notices this and says "Don't worry, that's natural. We'll stretch that throat of yours out so that you can take my cock freely."
She brings you back off of her dick, letting you take a breath and rest your jaw for a second, before pulling you back in. Inch by inch, she shoves her member deeper and deeper down your gullet, giving you little breaks over so often.
As this goes on, you feel the urge to gag slowly disappear and you manage to take more and more of her into your throat. You manage to get most of her cock inside of you without resistance, but the last couple of inches always seem to make you ****.
Sia let's go of your head and says "Well, now that we've broken you in a bit, go ahead and finish the job my little cock sucker."
You take up the responsibility with dedication and start to bob up and down her shaft once more. You easily take half of her 12-inch length inside of you and decide to work with that for a while. You start quickly moving up and down her dick, making it just barely poke the back of your throat with every entry. To make this even better for her, you move your hands up to her giant balls and start massaging them as best as you can. Sia lets out another moan from this but allows you to continue. You can feel her nuts pumping and creating semen non-stop. You slightly pull on them, roll them around in your hands and just play with them all while slobbering over her shaft.
After a while, you feel more confident and start taking her cock deeper in your throat. Since her tip has covered the inside of your throat in precum, her shaft easily slides in and out as you take almost all of her length inside of you with each movement. Wet slurping sounds and quiet moans fill the room as you worship the greatness of Sia's member. Another while later, you start shoving your face all the way down her shaft, letting her balls touch your chin and her toned stomach press against your forehead. You gag and ****, but it doesn't phase you as all you worry about is getting Sia to cum. After you increase your tempo more and more, Sia places her hands back on top of your head and guides you down her shaft.
Soon enough, you feel her getting closer and closer to orgasm. Her member becomes hotter and harder and her balls start churning up a storm of cum. All this time, you've been aching to taste Sia's delicious cum, her precum acting as an appetizer. You start throat fucking yourself on her cock, letting spit fly everywhere from your violent deepthroat. You hear her moaning get louder and louder, faster and faster when finally, she let's out a yell and orgasms. You quickly move your lips back over her tip in order to taste every last drop of her spunk. Your hands grip her shaft tightly and start milking her cock of all it's got. You feel her cock tense up and release a giant load of sperm straight in your mouth. You quickly get your throat to work and start chugging down her nut as fast as you can, knowing that there's probably a lot more to come.
You're absolutely right. Another giant cumshot fills your mouth mere milliseconds after the first one. You start swallowing Sia's thick and salty cum non-stop, as more and more gets pumped inside you. If this were a speed drinking competition, you'd definitely take gold, because the rate at which you're gulping down Sia's cum is astounding. After swallowing more than a liter of dickgirl cum, your throat starts feeling tired of swallowing and some of it starts leaking out your mouth. You quickly realize this and take action. You don't want to waste a single drop of Sia's seed, so you do the only thing that seems logical. You remove your hands from her dick and shove your face all the way down her shaft, letting her cum pump straight down your throat and into your stomach. The sudden sensation makes Sia orgasm again, and even more, jizz shoot from her dick. Some amount of cum still manages to drip from the sides of your mouth, but you patiently stay balls deep down her dick and wait until she's finished cumming.
After a long orgasm and a few gallons of jizz in your stomach, you start feeling her member shrink inside of your mouth. You slowly pull her cock out of your hungry mouth with a *pop* sound, making sure to collect any cum left over on it. You use your hands to collect any sperm that leaked out on your face and bring it between your lips. You take a big gulp, swallowing anything left in your mouth and letting out a big sigh of relief. As you do, the lights in the room come blazing back and you slightly shut your eyes until they get used to the brightness.
You pat yourself on the belly and feel that it's slightly expanded from all of the jizz you swallowed. You hear Sia let out a big sigh as well and place her hand on top of your head.
She begins gently petting you and says "What a good boy you are, not wasting a single drop. Sia's real proud of you, you know that right?"
You nod your head with a smile on your face as you look up to her. You see her well hung cock dangle between her toned thighs as she leans down and gives you another kiss on your forehead.
The speakers click on and Alan starts speaking to conclude the test. "Well, not really according to plan, but still a good test. You were supposed to make some sort of attempt at an escape, but either by intimidation or seduction, Sia managed to keep you in one place, which is impressive on its own. Anyway, this concludes the test, so return to your room when ready."
You get up off your knees and hug Sia goodbye as you each return to your rooms.
You got the "Hungry child" ending with Sia.
Test complete!
