Sci-Fi Boob Transformation – The Expansion Device – NAT – A – 0007 – 4-3-23 – Part 1

Do you like big tits? How about MASSIVE TITTIES?! My boobs get HUGE for you in this sci-fi boob transformation roleplay!

You’re one of my best friends at college

I want us to be more than friends, but you are always so busy! Honestly, I’m impressed by your dedication to your work. Recently you got an internship at some big tech company. At least that’s what I thought… I’m not sure what it is you do there. You say you can’t talk about it, but the technology you’re helping to develop is “going to revolutionize the beauty industry as we know it.” But what does that mean?! It makes me so curious!

One night, we’re watching tv at your place.

I decided this is my chance to investigate.  I don’t see any papers lying around, but this weird little device is on your desk. Is this what you’ve been working on? It doesn’t seem so special to me. There’s tiny writing on the top of the box near four buttons. I bend over to read it, It just says “On/Off. 10%. 50%. 100%.”. Curiosity overwhelms me and I turn it on. The device makes a loud whirring noise as it warms up. A little light on the box turns green and the device beeps 3 times. I figure that must mean it’s ready. But for what?  How exactly is this for the “beauty industry”?

A bright light beams out of the end of the device, straight at my boobs.

They shine with a sparkling golden glow that radiates from under my shirt, and I feel a tingling sensation overcome me. At that moment, I noticed my t-shirt is getting tighter… What’s happening to me?! Just as I start to panic, the device powers down. Nervously, I walk over to your bedroom mirror and lift my shirt. Whoa! My breasts have never, EVER been this big. My once small-ish B cup titties are now full, luscious C’s. And damn they look good! I’ve always been secretly jealous of my friends with bigger boobs. I always felt like my tiny tits were holding me back from getting a great guy. But not anymore. Maybe now that I have a nice set of bouncy boobs, I can get you to notice me!

I start to leave your room, then stop.

I only used the device at 10% power. Ten. Percent. This is your expansion device. You aren’t going to be impressed my boobs went up just one cup size. Perhaps if I just boost them up a bit more… 50% couldn’t hurt, right? I examine myself in your mirror. Yes, I must go bigger. The device whirrs to life yet again. I bend over squarely in front of the device, trying to mimic the same position I was in before. The green light appears & the device beeps 3 times. It’s ready. As I am about to push the button for 50%, I hear the door open behind me. “What are you doing?!” you shout at me, panicked. Startled, I miss the 50% button and instead hit the button that says 100%.
