"Give me something XXL!"Mark said
"Right this way sir."She gestures
"This is the largest dildo we have to offer."She states
"Doesn't look so big to me."Mark responded
"Oh I a sure you it's quite large. You see it has size changing principles, as such we keep it small for easy display. "She retorted
"Ok I'll take it."Mark says
"Oh you drive a hard bargain but you win!"She emotes Dramatically "Very Well!"she then reverts back to her calm state"Will that be cash or credit."
"Uhhh Cash."Mark Said
"Oh good we don't take credit. OH and I almost forgot this is how large it gets!"She responded as she Pulled out a piece of paper on it depicted:
A man holding a massive dildo with height markers at the side showing the man to be 6 foot tall and the dildo to be 4 foot long.
"Come to daddy big BOY!"Mark exclaimed upon seeing the massive dildo
As Mark arrived home Giddy with excitement he slammed the door shut and started stripping.
He pulled out the dildo and lubed it up and shoved it up his ass deciding it would be easier to get it up there if he left it at it's 5 inch length.
After it was in however he made made it larger. 1 foot long to be exact and when he did his muscles grew.
The deeper he got it the bigger they got.
"OH that's a lot of pressure!!!"he grunted
()
he then changed it again now 2 feet and for some reason it lost the balls.
He shoved it deeper and deeper. as he did he felt it press into his cock inside him.
"That's odd that's not how that works?"He thought for only a second as his mind and body remembered all the pleasure he was feeling.
He shoved deeper and then he noticed his dick and balls growing along with the still growing muscles.
Then for reasons unbeknownst to him yet he grew a beard.
The pleasure was astounding"OH FUCK YES!!!"He shouted in pure pleasure as he shoved deeper and stroked harder.
"YES!"He moaned as he grabbed his and stretched testicles.
()
"Oh yes this is amazing do I dare!?"He contemplated before taking it to its full 4 feet.
"OH GOD YESSSS"He screamed in delight and passed out just from the girth its self as well as some thing else.
When Mark opened his eyes he was in the arms of a VERY LARGE MAN! Mark felt the other man's a 4 foot Cock inside him.
"you're awake lets continue we were so close!" the man spoke
"Who are you?"Mark inquired
"I'm you or at least I will be you. Well more like we will be the same person after we're finished" The Man responded
"Why did I grow a beard?"Mark asked
"you're progressing through my age states. when we're done you'll go back to not having one But, if I know My body that wont last long."the man answered
"What if I don't want tho be the same person as you?"
"Do you really not want this body?"The man asked then flexed his freakish muscles causing Mark so much arousal he began to pre-Cum Buckets.
"No I want all that "Mark moaned in pleasure
"Good Then Let us Finish!" The Man exclaimed as he stood up with Mark still attached to his dick so that he was hanging in mid air.
The man then lubed up his dick more and more then began thrusting.
In out in out The man trusted Mark was crying the pleasure was so much.
"Fuck me fuck me harder!" Mark Screamed and so the man did
They fucked for what felt like hours until finally mark Came.
An eruption of cum spewed forth from his raging member! Covering the walls, ceiling, furniture and, himself in boiling hot man milk.
The man diapered. Then dildo slithered up up Mark's ass hole causing him to cum harder gallons upon gallons of cum pouring out of his dick like a broken faucet seemingly never ending.He grew taller to 8 foot tall.
And when it was over he was laying on the floor in a 4 inch puddle of boiling hot cum, with hardly a second passed since he passed out.
"Oh god that felt good"Mark sighed "I need a shower."
Mark went to his bathroom and Showered off all the cum. He exited toweled off tossed the towel aside and looked in the mirror.
