Clitoral toys? Nope. Wands? Nope. Butt plugs? Definitely not. Viv roamed through the store’s aisles, desperate.

All those other things had given her some degree of pleasure in the past (besides butt plugs — maybe someday), but her pussy was crying for penetration. The same penetration she’d been denying it all these years.

Arriving at the right section, she resisted grabbing the 7.5-inchers that lined the shelves. She wasn’t going to repeat the mistakes of her high school sex life — she’d just find the tiniest, thinnest model they had.

THE PENCIL. Perfect. While it wasn’t quite skinny as its name suggested, it wasn’t much bigger, around the length and width of a dry-erase marker. She almost ran to the cash register to buy it for herself, giddy with lust-fueled excitement.

Scanning the barcode, Viv noticed the price and frowned. $34. Even with her 60% discount, she didn’t want to spend nearly $15 on a toy that might not fit. With her income, she needed to be sure whatever she bought worked.

Well… there were no windows…

Viv pushed down her shorts and panties, and, using the counter as support, gently slid her naked ass down onto the black marble floor. A little gross, sure, but nobody had come in since she mopped.

She looked at the tiny beige cock with concern. The Spellcaster had been a literal stick; this was slightly thicker, and its similarity to the real thing gave her painful flashbacks.

But god, she needed something in there. She might as well just try it. Her left hand guided the dick to her wet folds, and she began to softly insert the tip—

OW. There was the wince. The tiny cock felt like it was splitting her entrance. She knew she shouldn’t have pushed her limits.

But then… then it felt good. That initial half-second of pain left no traces. Cautious, she slid it in a little further. And further.

I could actually get used to this, she thought, now sliding the cock in and out of her at a slow pace. She let out a blissful whimper. Even without vibration, this felt better than the Spellcaster did.

As she kept up her rocking motion, each push went a little deeper than the last. Deeper thrusts, faster thrusts, more forceful thrusts. It was if she was purposefully testing herself to see when she’d feel pain.

But Viv felt nothing but ecstasy, even when she had pushed the cock in up to its five inch hilt, cupping its grape-sized balls in her palm. Between increasing moans, she giggled — it just looked so tiny in her hand. It was almost like she needed something…

Bigger.

Viv shocked herself with her own thought. She, owner of the world’s most pathetic pussy, thought she could take on a bigger cock? Did she have a death wish or something? That prototype must have sautéed her brain along with her privates.

And yet… she had taken that last cock hard. Maybe her pussy was enjoying a late growth spurt. Why not test her limits?

I’ll just wash you off later, she thought, pulling the wet pencil dick out with a pop and putting it on the counter. She slid her shorts and panties off over her shoes, setting them on the floor. No reason to roll them back up if she was just going to take them off again.

THE AVERAGE JOHNSON. Its packaging claimed the dildo stood precisely at the worldwide average of 5.16 inches — a little smaller than Viv would have guessed. That last one she had taken was nearly as long.

But its width, 1.8 inches, would be the real challenge. Doing some hazy math as she sat down and removed the packaging, she figured that would make its girth over twice as big as the Pencil’s. She guided it towards her pussy as she inhaled.

Okay. Deep breaths. You’re not going to take it all, you’re just going to see…

Fuck. There was that wince again. But same as the last one, it vanished immediately, and Viv looked down in shock to see her hungry pussy had already swallowed the first inch. What the hell was going on?

Skeptically, she slid the Johnson in further and further. It was stretching her pussy, alright — but it was as if her pussy was stretching with it.

“Oh my god!,” Viv cried, excited by how much she was taking. This late puberty of hers must have grown her pussy more than she thought. She started maneuvering the cock with the same force she had used on the last one.

“Oh my god,” she cried again, with a much more lustful intonation this time.

The catharsis nearly felt better than the physical pleasure. Here she was, taking on an average size penis. She’d finally be able to have a normal sex life. No more turning down dates or sulking awkwardly at 2am frat parties while her friends all scrambled for rooms to fuck in.

Viv was finally pushing herself — and her pussy was sure as hell taking it.

And what was that phrase? Give an inch, take a mile? She was caught in too much horny, hazy pleasure to know if it made sense here.

She just knew she needed a bigger cock.

~~~

BIG BEN. It was big, alright — not as big as she’d seen in some videos, but big. Seven inches of length, six inches of girth. Big enough.

As big as Jake was, Viv thought. She was ripping through the clamshell packaging without stopping to think how she’d put it back on. Sitting her sweaty ass down again, she cupped the dildo’s big dark balls. The base was bigger than her palm.

Every part of her body was saying no to this. Every part except the only one that mattered right now.

Closing her eyes, she braced for impact.

“FuuuuuuUUuuCkkkk”, she cried as the tip burst through her slit. Even at the speed of a banana slug it felt like a drill boring into her. And then, as with the others, the pain vanished.

Viv winked a cautious eye open. She could believe what she was seeing, but she couldn’t believe what she was feeling. As the cock pressed forward, it was actually making her pussy grow. This growth spurt wasn’t from the past few years, it was from the past few seconds.

She could feel her entire abdomen tingle as she fed herself more of Ben, the silicone cock now six inches deep in her pussy. It felt like the cells in her organs were rearranging themselves to make room for the dick she had been missing all these years. An electric current of pleasure seemed to be flowing from her pussy and powering her entire body.

Electricity! All of this had started happening when the Spellcaster had shocked her. But how would that make sense? It definitely hadn’t fried her nerve endings — while the pain was gone, she felt more pleasure than ever.

Wait... Spellcaster… what had she thought right before the zap again? She wished every toy…

“…could fit like that,” she realized aloud between heavy breaths, still fucking herself silly with most of Big Ben’s length.

Holy shit. That meant that she could fit…

Anything. She dramatically shoved in the final inch.

But the magic — or nanobots, or vague mystical force — growing Vivian Primrose’s pussy had run out of space. Her body could only rearrange itself so much, and it had no room left to offer her needy cunt.

And so the magic started growing Vivian.

With that final inch, her back walls shot out an inch, and the rest of her body kept up proportionally. Her shirt shrank. Her toes bumped up against the tops of her white sneakers. Her bare butt squeaked as it stretched out along the marble floor.

It was enough to knock Viv out of her state of bliss. What the fuck was that?

Whatever, the now 5’7 woman thought, yanking Ben out like a ragdoll and tossing the toy to the floor. I’ve got a magical pussy to test…

Her eyes caught the giant, dial-controlled dildo Lana had been fondling earlier.

…and the perfect fucktoy to start with.
