"huuuugh," I groaned as I tried to sit up. I looked up to see Sam towering over me with her arms crossed and legs kneeling on the ground. "I... Wish... I was... Bigger," I said between grunts, still exhausted from making out. "What was that honey?" Sam said, tilting her head to one side and leaning up against me. I can see the massive valley of cleavage being just inches from my face, but it seemed to be traveling further away as I grew taller. As I grew, my energy quickly came back to me to waves.
I leaned forward and cupped the back of Sam's head to give her a deep kiss. While we made out slowly, I continued stretching taller and taller until I was about Sam's height when she noticed something was off. "Have you been working out? Your body feels tighter against my boobs." Sam arched her back and gave off a loud moan as I continued to grow taller than her. Now that I was a couple inches taller than her, I quickly picked her up and pinned her against the wall with both of us standing up. She let out another deep moan into my mouth, my head continued to grow taller until eventually our lips parted. Now that I was about a foot taller than her, she crouched down and tore off the remainder of my shorts and began to suck my meat.
"Bigger baby, I want it bigger," Sam said between breaths. I quickly wished for my dick to grow twice as fast, now being nearly a foot long. Sam yelped as the added length surprised her, bit eventually she was able to deep throat the entire thing just before I hit my head on the ceiling. "Shit," I thought, "I wish I'd stop growing." I figured I must've been about 8 feet tall. Looking down at Sam I saw her crouching down to continue sucking my meat, she looked up at me and said "bigger baby, I can take it." "If I can't grow any taller," I thought, "maybe I ought to shrink Sam a bit, I wish Sam would shrink for 4 feet tall. Half my height seemed about right." I looked down to see Sam quickly loose height, first her clothes became baggy and fell off, followed by her needing to stand up on her toes to be able to reach my penis. All of this growing and shrinking finally built up to me blowing my load right into Sam who yelped at first but then quickly began to swallow every last drop.
