Chapter 12
Which one does she pick?
"Earthquake" (Vibrating)
As Myra walks around and ponders her next move, she swiftly moves to a far-off table and picks up her dildo of choice. As she brings it closer to you, you take a second to inspect it. It's shaped like a dick, not that big of a surprise to you. It's a bright green color and looks around 8 inches long. It also has a remote sticking out the back end of it. The only thing on the remote is a small dial and a little display above it.
Myra approaches the table you're laying out on and says "I like to call this little guy "Earthquake". You'll find out why soon enough. Let's just say that I took a basic vibrating dildo and... upgraded it. Now come on, spread those cheeks for mommy!"
Myra pours some of her special lube all over the green shaft of the dildo and brings it over to your asshole. You can feel the tip press hard against your sphincter until it pops in. Your ass starts swallowing the girthy length of the toy, inch by inch. As the dildo slides deeper and deeper in your ass, you start moaning from the sensation of it stretching you out, since the lube has made you extra tight. Once the shaft runs across your prostate, your dick jumps to life and quickly gets fully erect.
Myra notices and says "Huh, hard already? Don't get ahead of yourself buddy, the fun hasn't even started yet."
After finally shoving the whole 8-inch dong inside your anus, you let out a slight breath of relief and look down to see what Myra has planned next. She keeps one hand on the dildo, making sure your ass doesn't push it out and grabs the remote with her other hand. Her fingers grasp the dial and start slowly turning it clockwise. You watch the little LED display and see that number start to appear on it. It was set to "0" but that quickly changes to a "1", then a "2" and so on. You start feeling a weird sensation inside of you. The dildo starts vibrating!
At first, you don't feel anything much, but as the numbers get bigger and bigger, the vibration becomes more noticeable. When the dial reaches "10" you can feel the dildo shaking pretty prominently inside you.
Myra stops turning the dial, looks back at you and says "Let's not get carried away just yet. Gotta ease you into the higher levels."
She grabs the dildo and starts pulling it outside of your ass. You slightly moan as the twitchy shaft slides across your rectum and prostate. Once she brings it about halfway out, she shoves it back in again. Soon enough, you're being fucked by a giant vibrator. A few minutes pass as your ass gets accustomed to the toy, and that's when Myra decides to REALLY get this party going. She reaches her hand down to the dial and starts twisting, slowly making the numbers on the tiny screen get bigger, all while still fucking you at the same time.
Once the dial is set to "30", you already feel like your whole body is shaking from the vibrations. The pleasant stimulation of your prostate has got you breathing heavy and your cock twitching with pleasure. Precum starts dripping from your tip as you get fucked by the long and shaky toy.
As Myra slowly turns the dial more and more she says "We're not even halfway there. This thing goes up to "100", so you better strap in for a wild ride, cowboy!"
Myra begins pushing and pulling the dildo inside of you faster and faster, all while increasing the vibration level at a steady pace. You start moaning more and more and your cock goes as hard as it can from the immense stimulation that you're getting. After a while, the vibration level reaches "50" and you feel like you're being drilled from the inside. Your body gets hotter and hotter when finally, you can't hold it in any longer. With a loud moan, your cock sprays forth a giant load of jizz up in the air, some landing on the table and your body, and some grazing Myra.
Seeing this, she quickly shoves the dildo as far up your ass as she can, letting it rumble deep in your rectum and says "I told you to not get ahead of yourself! If this is all it takes to get you off, you probably can't even handle the higher levels. Yeah, I'm done with you."
After saying this, she swiftly pulls the whole 8-inch dong out of your ass, leaving you gaping open.
WHAT? This can't end yet! You still need that giant toy cock inside of you, vibrating with full power! You start shaking your head violently and trying to plead with her to keep going. The gag in your mouth doesn't let you say anything comprehensive, but Myra seems to know what you're getting at.
She narrows her eyes and says "So you want more huh? In that case, you have to promise to not cum until I tell you, alright? Do you get that?"
You quickly start shaking your head, wanting that cock to fuck your ass again.
Myra says "Fine then, here we go!" and quickly shoves the entire length back inside your quivering anus with one motion.
You moan in delight and your body shudders at the feeling. Myra fucks you slowly at first but swiftly gets back to her previous rhythm. Once again, she starts turning the dial, raising the vibration level to "60", then "70", then "80"! Your ass feels like a mixing bowl, and the dildo is the whisk. Your whole body trembles from the vibrations the toy puts out, and they are quite powerful. There is also a noticeable dampening effect when the dildo slides into your ass.
"Here we go, the final ten!" Says Myra, turning the last positions of the dial.
As you finally hear a *click* sound come from the dial, the vibrations start becoming extremely noticeable. The jump from "99" to "100" didn't feel like any of the other ones. It's like the toy almost doubled its power. Your moans become a garbled mess of noises and your whole body, from head to toe, starts shaking. Even your vision becomes shaky. It feels like a mini-gun is going off inside your anus. The stimulation of your prostate is unbelievable, as the intense vibration sends your dick into a precum spewing, rock solid mode. You clench your eyes, trying not to cum yet and feeling out the sensations for as long as you can.
Myra speaks up, saying "Once I shove this into your ass, you can't cum for a minute. Count out every second, or else it doesn't count. Now...go!" She quickly stretches her arm forward, forcing the heavily vibrating toy inside your rectum. You need to cum, now, so you start counting out the seconds, out loud. The gag makes you sound ridiculous, but cumming is a priority over all else at this point.
"WHHNE, TFFOO, TWHEE, FOOOH..." You start loudly screaming out the seconds as your insides get shaken around like lottery machine balls.
There is a noticeable shaking bulge observable on your stomach, stretching up to your bellybutton, edging you ever closer to orgasm.
"TWHENTY WHHNE, TWHENTY TFOO..." Each second is tantalizingly getting you close to orgasm.
You could cum right now, but you can't imagine what Myra would do if you disobeyed her. The 8-inch vibrating monster in your ass shakes around violently, spreading the vibrations throughout every square inch of your skin.
"FHFTHHY FIIFE, FHFTHHY FIIIKKS..." You are almost there.
The torturous edging is just gonna make this orgasm even better, so you ride out the final seconds like a champ.
This has definitely been the longest minute of your life... "FHTHHY NGGGHN, FFIXHTYYY!"
Finishing your countdown, you finally let go of your suppression and let loose another giant stream of jizz. Your spunk covers your entire lower body and even slightly covers Myra's upper half. You ride out the orgasm for a full minute before the vibrations start feeling painfully uncomfortable to your sensitive dick. Myra slowly starts turning the dial counterclockwise, letting the vibrations settle down. After a minute, she makes the final jump from level "1" back to level "0" and pulls the dildo out of your rectum. You let out a deep exhale after your second orgasm from this toy and watch as she sets it back on the same table she got it from.
She looks down on you and says "Two whole orgasms huh? To be honest, I was expecting a bit more from you, but I guess "Earthquake" isn't as powerful as it once was. I think this calls for some... upgrades... Ah, but here I go trailing off. You did good, but that doesn't mean we're done yet..."
Is she done with you?
