Super Elasticity: User can stretch and contort their body in infinite and insane ways. May have other side-effects.
Huh. That sounds pretty cool. Images flashed in your mind of the hot MILF Elastigirl from The Incredibles, and so you eagerly aimed the remote at yourself and clicked submit.
ZAP!
Immediately, your body felt different, although it did not look any different from the outside. Instead of being a rigid skeleton encased in muscle and skin, you felt more akin to putty in a mold, as if your current form was merely a suggestion rather than a requirement.
You decided to test your ability simply at first, stretching your arm out in front of you. You were amazed as the usual limit no longer existed, and your arm just continued to arc across your bedroom, like a flesh-colored python with a hand.
Next, you turned your head, and giggled as it twisted around and around and around without difficulty, soon reaching 1080 degrees of rotation or more before you twisted it back.
Eventually, of course, your mind turned to a different part of your body. Reaching down, you yanked your pajama bottoms down your thighs and out sprung your fully erect average penis. It was already leaking pre, as it was extremely aroused by the hotness of your stretching ability.
Focusing on your dick, you watched in awe as it grew longer and longer, right in front of your face. Straight up toward the ceiling it extended, and you grew its thickness as well. Pretty soon you stopped it at the width of a 2-liter and the length of a yardstick. Focusing on your balls next, they swelled and expanded making you moan. There was an audible sloshing and groaning noise within them as they quickly surpassed cantaloupes until you finally stopped them at the size of prize-winning watermelons. They were so heavy now, probably 100 pounds each, weighing down the mattress between your legs.
"Fffffuck," you cooed, stretching your hands down to rub across the taut hairy scrotum.
Without needing to even think about it, you stretched your neck upward. It extended 2 feet, 3 feet, 4 feet, until you had a good vantage point above your gigantic mushroom-shaped glans.
You eagerly moved your face down to it and began kissing and licking at it, relishing at the taste. The purple skin of the head was so smooth, and the odor of semen coming from your enlarged piss-slit was irresistible. Down at the base of your massive cock, you stretched your hands around the shaft so you could stroke it up and down. This caused your pre to flow from your cock like a fountain.
You brought your face to your slit, stretched out your tongue, and swirled it around the entire orifice. Your eyes rolled back (all the way, actually) and you moaned as you continued swirling and swirling, all the while continuing to stroke yourself down below.
After a couple minutes of this, you stopped and looked down at your giant cockhead.
It just looked... so inviting.
Nervously, you lightly pressed your whole face against it, slickening your chin with pre. Then, you began pushing it in.
"Ohhh GODDDDD," you groaned, feeling your whole head effortlessly slither into your gaping pisshole. The entire inner tube pulsated and squelched around your head, and somehow it was slightly illuminated inside, the light bleeding through to show you the entire red gloopy interior. It allowed you to see all the way down to the dark hole at the entrance to your cock.
Your goal.
You moaned more and more as you slithered your head further and further into your cock. Occasionally, the urethra tightened around the intruder as your whole penis throbbed with pleasure.
Finally, you reached the bottom. Pushing through the smaller opening, you were presented with three smaller tubes: one to the left, one to the right, and one in the middle. You instantly knew where these three tubes led, and decided to enter the one on the right.
SCHHHHLOOOOOORRRRPPP!
With a grunt, you forced the smaller tube to stretch around your head and continued onward, until suddenly it opened up into a large ovular space.
You were inside your left testicle. Looking down, you saw a swirling pool of your own semen. It was ever gradually increasing in quantity as you got closer to orgasm, and you could hear a bubbling and squelching sound from the tepid sea of cum.
The overpowering smell of your cum almost made you pass out, but instead rose your arousal even further.
Stretching your neck inside more, your face was soon a mere inch from the fertile pool.
Delicately, you lolled out your tongue and dragged it up the thick gunk, catching a good spoonful or two in the scoop. Retracting it back into your mouth and swallowing, your body shuddered from the surprisingly delicious taste. It was so strong, so bitter, so salty, so smelly, and yet you were ravenous for more.
Eagerly, you stretched out your tongue over a foot long and used it to scoop up a quart of semen. Your mouth itself had to stretch around the tongue so you could swallow, but that required no effort at all.
Again you scooped up more cum, and again you swallowed. And again. And again.
Soon after, you just put your mouth against the top of the fluid mass and began sucking and slurping it up.
You hardly noticed as the level of cum against the wall of your testicle was going down and down.
GULP GULP GULP GULP GULP
*Outside POV*
"So, what was in the package sweetie?" your mom asked as she walked back to your open doorway. She stopped in her tracks and stared at her son's gigantic dick and balls, with what appeared to be his neck stretched out from his shoulders and down his cockhole.
"Oh my god, my cum tastes so fucking good!" she heard your muffled voice yell from within your left nut, which occasionally bulged from the motion of your head.
Your mom chuckled and shook her head. "That boy's not gonna want any dinner if he swallows all of his cum again."
She took a mental picture of your enormous genitals (for later use) and left, heading back down the stairs to the kitchen.
*Your POV*
BBUUUUUUURRRRRRRGHHH!
Your loud belch echoed around the inside of your nut. It was almost empty now, with only maybe a gallon or two of your thick delicious sperm remaining at the bottom of your egg-shaped fleshy chamber.
"God DAMN," you said before laughing.
You wanted to continue. For a moment you considering going into your right testicle and drinking its bounty dry as well, but then your arms outside felt your belly.
"Holy shit, it feels like I'm nine months pregnant with octuplets!" you gawped. Your hands slid around the giant gut that you couldn't currently see. It rested heavily against the base of your huge cock, and jiggled with every slight motion of your body.
Rather than spending another thirty minutes gulping down cum, you decided to give your stomach a rest and explore deeper into your body.
You retracted your neck, slurping your head back into the thin tube of your vas deferens. Once you were back at the entrance of your cock, you decided to press through the middle tube, into your bladder.
A small pool of piss was inside of it, but you knew from horny experience that it wouldn't taste very nice, so you continued onward.
Somehow, you ended up in your intestines, and continued sliding your head deeper and deeper through them, even as smelly gunk accumulated on your face.
After a few more minutes of this, you spotted light up ahead. It peeked through what you knew to be the inside of your sphincter.
With a grin, you slithered your head up to it and groaned as you pushed through.
SCHHHLLLLLOP!
You took a deep breath of fresh air, your whole head sticking out of your asshole, being squeezed on the sides by your cushy hairy asscheeks.
To allow this, you had rolled yourself onto your side, although your cock was still aiming up at the ceiling because of your neck keeping it upright.
Foot after foot of your neck exited your asshole as you snaked your head upward to look at yourself.
You couldn't help but laugh. Your body looked ridiculous.
Your engorged smooth belly was larger than an exercise ball, only deflated looking due to its weight being on its side.
Your giant ballsack hung over the side of your bed, and your gargantuan nads almost touched the floor.
Stretching over to your almost-empty left testicle, you smiled before pressing your lips against the sweaty musky skin and giving it a deep kiss. You pretended its gurgling was a pleased response.
Returning to a vantage point above your body, you spotted the remote and picked it up with your distant hand.
You stretched your arm up with the remote until it was only a couple feet away from your head.
"God, this is amazing," you said giddily. "I have got to give this ability to someone else!"
You figured since you were infinitely stretchable, you didn't really need to return your body to its original shape, sliding your head all the way back through your body and out your cock. It was like you thought earlier: the human form was now really more of a suggestion than anything.
Gripping the remote tightly, you decided to travel the house as a head on an endlessly-stretching neck to find your family members.
What did you do next?
