Roll giggles as the sliding door rubs against Roll's breasts as it opens up. Within moments, Roll floats out of the shaft and up into the air. She gleefully watches the ground become more distant as she is propelled into her air by her breasts and butt, all of which start to expand again once Roll is high enough in the air.

"Ooooh...it's working...since my boobs and butt are so full of helium, I should have more than enough to allow me to escape the planet's atmosphere. It might be a bit extreme, but that's what it takes to ensure that I'll never stop expanding." she says.

Sure enough, the combination of helium and lack of gravity cause Roll to speed up until she is moving fast enough to pull away from the earth's gravitational pull. She grins widely as gets further away from the planet, pleasured both by achieving her goal by the wild expansion of her breasts. "Ahhh...what a rush! I can't believe how good it feels to have my urge to grow perpetually fulfilled!" she exclaims.

She giggles and waves toward the planet. "Seeya, Earth. Hope my girl-spheres are as big as you one day!" she says, giggling a little as her breasts and butt continue to swell outward with no sign of stopping, each sphere a little larger than one of the largest cities on Earth.

Roll sighs in content. "Hehe, look out universe, here comes Roll!" she happily exclaims as she flies out into deep space.

And so, Roll's breasts and butt continue to expand as time goes on. Roll finds that when objects start to collide with her spheres or vice versa, whatever they touch get absorbed into them. As time goes on, Roll bounces around the universe, absorbing anything and everything in her path. By the time she's absorbed everything, each sphere is literally as big as the old universe was, and still growing.

Roll giggles at the thought of the whole universe being composed of her breasts and butt and what is inside them. "Ahhh...now that everything is inside my girl-parts, there's nothing left to do but enjoy the growth the universes inside them will provide." she says, as she starts to relax and fully enjoy the feeling of her expansion.
