[F4A] Your girlfriend agrees to let you shrink her for a night. You're having second thoughts about changing her back...

NSFW RP - Ongoing

"I mean, that was...that was unlike anything I've ever experienced, that's for sure," she tells you, her little voice a higher pitch than it was yesterday. She was incredibly insecure at the discovery of the voice change last night, but you find it absolutely adorable.

You almost can't believe this. You could just pinch yourself right now. After many months of slowly introducing the idea then working your way up to having deeper conversations about it, your longtime girlfriend finally decided to indulge your biggest fantasy: to have a night with her where she's shrunken down to just four inches tall. When the shrink ray had been delivered months ago, she didn't believe it was legit. Why would she? Shrinking wasn't possible, right? But after you tested it out on a few objects, those doubts immediately gave way to shocked disbelief. It worked. It was undeniable. You both saw it work with your naked eyes.

The next challenge was how concerned she was about the safety of it — and ensuring that it had the ability to reverse her back to her full size. Sure enough, you managed to restore those test objects' original sizes with the device. Still, she was understandably scared. But with time, patience, and reassurance, she eventually came around. You were almost shocked that she was even somewhat open to entertaining the idea to begin with, so waiting a little longer for her to really think on it was something you were more than willing to do. Eventually, you both set a date on the calendar and made sure all plans were clear.

And the resulting night — last night — was absolutely incredible. It was a night you'd never forget, a fantasy you never believed you'd be able to act on. It was a mix of scenarios you had both agreed on ahead of time — most of them your ideas, considering it was, after all, your fantasy, but a few she came up with too. You played out her slowly taking off her clothes piece by piece like a strip tease as you played music on your phone, smiled, and stared while gripping your bulge below the coffee table. You had gotten a cheap hamster cage because you wanted the experience of slowly lowering her into it as she kicked and screamed in protest. She grasped the bars with her tiny hands and screamed and pleaded up at you convincingly, just the way you had asked her to, which drove you wild. You played out the whole scene of you commanding her to put the embarrassing doll dress on. Later, you lay back on the couch as she cuddled up against your chest. She eventually carefully made her way down to your crotch, and the moment you could feel her little feet press against your hardening warmth below the fabric, you bit your lip in anticipation.

And that was all just the foreplay. Having a girlfriend who was smaller than your cock was always your biggest fantasy, and pleasing her was easier than it had ever been. Gingerly rubbing your wet finger over her in rhythmic little circles, teasing her and dangling her over your mouth, licking and kissing her sensitive spots, lapping her up, humming loudly while planting her butt firmly over your cushy, warm, wet lips — it all drove her beyond the edge multiple times. But to actually grasp her within your sweaty palm and sandwich her between your hand and your shaft was the most incredible dream come true. Of course, you had to be careful — you didn't want her getting injured — but in no time, and thanks to some lube, you found the perfect balance between safety and intensity as you swiftly glided your tiny girlfriend up and down your length, the sensation of all her little curves and contours, not to mention the indentations of her helpless little hands and knees, driving you beyond wild. It was incredible. Better than the many years you fantasized about it.

You both slept in late the next morning — you had set up a makeshift bed for her on your nightstand with a couple of your t-shirts — and in this moment, you've both just woken up and started reflecting on the previous night together. She's still that itty bitty action figure size, and you're lying on your back with your head propped up on two pillows, lovingly staring down at her miniature form resting there on the bare skin of your chest. God, it feels good having her little body on you like that.

"I'm so glad you liked it sweetie," you say, your nose scrunching as your smile widens. You love her like this. She's perfect.

Sooner or later, this moment is going to come to an end. Sure, she's going to play along with your little fantasy for a little longer — she loves and trusts you, after all, and agreed to do this to make you happy — but somewhere far back in your brain, you can't help but wonder how soon it will be until she says it's time to grab the shrink ray and restore her size.

Maybe she'd do this again though? It doesn't seem like she had a bad time, to say the least.

Your free hand gently moves towards her. She cranes her neck back to smile up at you before glancing at your hand. You begin softly petting her up and down one side of her body.

But wait. A thought occurs to you. What if you just...don't change her back?

No. No no, that'd be crazy. That's a ridiculous thing to even think.

But...wait.

...Wait, no no no. No, you can't do that. You wave away the thought.

"Not to be crude," you add in a soft, tired tone as you smirk down at her, "but getting a chance to kiss and lick at you like that...and the little sounds you were making? That drove me wild."

She lets out a little embarrassed laugh.

"And when you started hugging and squeezing me?" you continue. "Oh my God. That felt amazing."

She laughs a little more then bites her lip and shakes her head. "It's...it's bigger than I am," she says, flustered. Her new voice doesn't carry very far. It's so little.

The way she says that is an incredible turn-on, and you already feel yourself getting hard under your boxers.

Man, you really, really don't want to have to change her back. You...don't have to, really, do you? I mean yeah, you had an agreement and everything, but what would she even be able to do about it? What if you "accidentally" broke the shrink ray? Sure, she'd probably be angry for a while, but eventually she'd have no choice to accept it, right? And it's not like she hated last night. She definitely didn't hate it when you pinned her in your hand and started suckling on her, or when you held her over her own vibrator and locked her in place over it so she couldn't squirm away. That had been one of her own ideas, even.

She shifts, and you watch her intently. She rises up to a seated position, then twists her upper body around to peer up at your face. You catch a glimpse of one of her breasts by the way she's turned around. They've always been sexy to you, but now they're the size of ripe, perfect little blueberries. You remember the way you could latch onto both of them at the same time last night — in between a gentle hold of your index finger and thumb.

Why can't you two just be like this all the time? You'd take really good care of her. You'd totally pamper her. She wouldn't have to worry about anything anymore. She had you to take care of her and all of her needs.

Wait, no. That's...you can't do that...

You really just wish she were this small all the time. 24 hours a day, 7 days a week. Your girlfriend is just too perfect like this to change back. God, it would be perfect... Why not? All you'd have to do is just...You even already have the cage to keep her safe when you're at work.

Wait, stop. You can't do that. That's wrong. You can't.

But she's perfect. She's perfect like this. This is perfect. You have to have this forever. You have to. She's your own secret little doll. It was meant to be this way.

No no. No, you...you can't.

...But you're going to.
