As Ty lay under Dustin's massive body she contemplated what had just happened. Dustin had manipulated her into getting what he wanted, though she couldn't argue with the results she felt some punishment was in order.
"So Ty, you wanna see how this fat cock feels in your ass dont ya?"
said Dustin certain that he could still get Ty to do whatever he liked with his new lustful body.
Ty was unphased, "Take the dildo out of you ass and put it in mine"
Dustin pulled the rest of his 8 inch soft cock out of Ty, already getting harder he wanted to ignore the command and instead plunge his own cock in Ty's ass but his body betrayed his wishes and did as Ty said.
As the dildo went into Ty's lubed ass she spoke to her step brother,
"Clean your cum out of my pussy with your tongue,"
Dustin felt his head move closer between her thighs, his tongue reached out for Ty's cunt and obeyed her by first lapping up any of the cum left on her pussy lips. Ty reacted with soft moans as she then told Dustin to "Pump the dildo faster!"
Ty felt Dustins tongue plunge deeper in her cunt as the dildo sped up and sent Ty's head rolling in pleasure. She grabbed Dustin's head, pushed it into her pussy and moaned "deeper!" as she wished for his tongue to grow in length. She felt his tongue start to snake up her. As Dustin tasted more of the mixture of his cum and Ty's juices he could feel more control over his newly lengthened tongue. As if a whole new world of movement had been opened up to him, corkscrews and snaking movements, a wholly different kind of tongue fucking that he now explored inside Ty each making her shudder more than the last. Ty nearly lost herself in the intensity of it all but she still had a punishment to carry out. She gathered and calmed herself as much as she could then told him,
"D-don't stop what you're doing and aahhuhhh bring your fat dick up here aaahh!"
Without moving his head and hands from where they were needed, Dustin rotated his body so that his bulging ass and cock were right in Ty's face. She felt up the powerful tree trunk thighs and beautifly spherical glutes that had been presented before her, Ty's deft hands moved to Dustin's massive rod and got to work. She worked the head with her left and the shaft with her right, and couldn't help but be drawn in by the musk coming off of Dustin's large egg sized nuts. However before she placed her mouth on them she mused at the ridiculousness of a large cock with such comparatively small nuts, so she wished for them to grow to the size of grapefruits. Maybe she had overdone it but at this point she didn't care.
Dustin felt a delectable warmth from his crotch as his balls inflated in size, though he only realized they had grown when he felt his new fat nuts brush up against his thighs. Slightly stunned by the growth his tongue and hands stopped moving only but for a split second before he got right back to tongue and dildo fucking Ty. He felt Ty's mouth on one of his balls and pulled an ear to ear grin face deep in Ty's cunt, he was enjoying this. And his enjoyment only increased as he felt Ty's mouth move from his nuts up the shaft of his foot long cock, onto his thick glans. She worked the wide spongy head with her mouth knowing it was pushing Dustin closer to a sort of pleasure madness. Dustin felt Ty drive herself deeper down his monster till her chin was against his pubes and his nuts were resting on her face. As she railed her throat with his 12"x7" member, Dustin felt a rythm begin to form between their all their movements. He pumped his hips into Ty's face in time with his tongue and the dildo he was using on her and Ty thrust herself into his cock and magnificent tongue work. Both did their best to both hold out cumming and give each other the most pleasure possible. Dustin found that the corkscrew motion had ty shuddering the most so he increased the vigor in his lengthened tongue, and used all of his remaining strength on the dildo. Not to be outdone Ty clamped down on Dustin's cock with her throat focusing on the head and massaging his heavy nuts with her delicate hands. She could feel the massive orbs filling with cum and getting heavier. Dustin's efforts were being rewarded as Ty moaned on Dustin's gargantuan fuck tool. Dustin began to think he had the upper hand and thought
"Soon i'll get Ty to orgasm so hard i can get her to agree to any wish including wish giving me the powers!"
But before he could begin to enact his plan he felt Ty pull her self off his cock and go back to working his cock with her hands. Confused he pulled his elongated tongue back into his mouth to try and protest but again before he could say a single word or utterance he felt something very strange. His cock wasnt bent at all but he could feel the thick tip pressed against his ass.
"Uhhh Ty what's happennnniiinnguhhh"
Dustin gripped the dildo in Ty's ass out of shock or pleasure? He couldn't tell. Ty used Distin's grip to pull herself off the dildo as she pushed Dustin's own cock deeper and deeper into his ass. Dustin's legs gave out and as his crotch landed on Ty's stomach he felt Ty's soft skin press against his stomach and thighs, but Dustin couldn't feel his dick pressed between Ty and his body at all. His ass was already stretched out by the dildo fucking earlier and easily accomodated his own monster cock. Dustin felt his ass grip his dick and his dick hit his g-spot, it was nearly too much as he held on to consiousness.
"See Dustin you need to learn who has the power here"
Ty said trying to pull himself from under Dustin's heavily muscled body. She shakily stood on the bed and imbued Dustin's immense rod with motion so that it would fuck Dustin by itself. Ty stepped off the bed her legs only just supporting her. She ran a hand up Dustin's powerful thighs to his ass grabbing a full hand of his muscular cheeks,
"In case you havent somehow figured out, I turned your cock into a living dildo and now you're fucking yourself."
"Oh oohh fu uhh c ck yo u Ty y uh uhh,"
the motion of the fucking was messing with Dustin's speech.
"Don't act like you didn't get completly taken by the pleasure of this whole thing. Remember when I made you put your cock in my face? I dispelled my wish to have you be my sex slave right after that."
"Uuh hhoo ohhh gaw hod"
Dustin moaned as he managed to lift himself onto his forearms. He had been reduced moaning and cries of satisfaction. His body was in a limp state from the amount of pleasure he was getting from feeling his large tool fuck himself.
Ty wished for him to lose the muscles Dustin had coerced Ty into giving him. As she ran a hand from his now shrinking ass and up his back to his soon to be scrawny neck she spoke,
"Dustin it's time you let go of your inhibitions and accept yourself and your desires"
Dustin felt Ty's hand on his neck pull his head up. Heopened his eyes to see ty's...
