Sam slowly looked up at you shocked as I squeezed up against the middle of her back which only reached my waist at her short stature.
I grabbed onto her skinny waist to hold her in place. Then after seeing the lust in my eyes she shifted her weight around and looked more confident like she had some kind of plan. This sent waves of pleasure up my spine as she subtly moved against my body. My mind began to fog over. "So..." I said softly, "what does Caterina look like?"
"Well, Caterina really is such a cool person and all, like she's super intelligent and all... but you already know that." She says quietly. "But secretly what I really love about her is just how massive she is, and she's still super confident in her looks, you get what I'm saying Pete?" I am barely listening to her as my grip gets tighter around her waist. "Like, it was probably all that time up in space that helped her grow so much, I think she's like a foot taller than you Pete, can you believe that?" I just imagined a woman with long, curly hair floating around a space station, her tight crop top and shorts perfectly outlining subtle curves. I hear Sam gasp as she shoots up a couple of inches, the top of her poofy hair barely scratching my chin.
"You know... She could've easily been a basketball or volleyball star if she wasn't an astronaut, her legs alone must be at least 5 feet tall." Sam shoots up another couple of inches, I can hear the seams in the astronaut suit begin to get strained. Sam slowly zips down the zipper some more, giving her massive rack some space to breathe. "I don't know if this costume can last any longer," she says, giggling a little as she slowly outgrows my grip on her waist. My heart is racing, by now she's nearly the same height as me and her butt comes up to my stomach. "You know, she isn't just her height that makes her so massive," Sam says soothingly, "her butt is so thick, I don't think even Andre the giant can fit the entire ass in his hands." Suddenly she lets out a loud squeak as she has her largest growth spurt yet, surpassing my height by a couple of inches. But now I'm having to lean forward in order to keep my arms around her. I'm basically hugging her waist from behind with her giant butt pushing against my lower chest.
Just then I hear a loud RIP as the legs of her astronaut costume rip in half, only being held up by the waist band and draping down her long, thick thighs. She begins to giggle, saying, "uh oh Petey, I can't see you in the mirror anymore, you alright back there? Am I getting too big for you, hmm?" She turns around and scoots me infront of her with ease. Looking up at the mirror she must be about half a foot taller than me, her boobs have grown alongside her height to be roughly the same size as my head, giving her an exaggerated figure alongside her massive butt. "I don't know Pete, I mean this sorta looks like her but I'm not quite there. I think she's still about a half a foot taller." With that she darts up in height, her astronaut costume barely hiding her gigantic body. She rests her boobs on top of my head, looking down at me in the mirror, "So honey, what would you like to do now?"
