Dustin approches Ty with a devilish smile, each step raising his arousal until he starts furiously jerking off.
"I can't thank you enough for all this" Dustin says while climbing Ty's hulking body with his tentacles.
"But I feel like theres something missing... Like you aren't affected by the mist."
Before Ty is able to respond, he pulls out a loud moan as Dustin's tentacles start pleasuring him. Two sucking on his nipples, one massaging his dick and another playing with his balls. The last two start slowly entering his asshole, streching it further.
"Just think how good this would feel if you were like us!"
Ty was letting the arousal wash over him while smilling at Dustin.
"All three of us together, we could rule over everything!"
Mark then approahed Ty from behind and grabbed both his arms, his dick feeling the other demon's stretched entrance.
"We need to be stronger, everyone needs to know who are the gods of this new world!"
Mark then fully plunged his dick in the warm entrance.
"JOIN US TY!"
Ty screamed in pleasure, his whole body shaking in arousal. Mark rapidly fucked him while Dustin set himself up on Ty's dick.
"We know you want this."
Dustin let himself slide further down his massive dick while his tentacles kept massaging him.
Ty then grasped Dustin's face and kissed him wildly. This was too much, his willpower was waving. And then, the two demons increased their tempo tenfold.
"HAAAAAAA EMBRACE US TY!"
Faster and faster Marks was now pistonning Ty's prostate with such strength, anybody else who have died from the act.
"BECOME OUR GOD!"
Dustin screamed as he flicked his now inhumanly long tongue.
"Haaaaaa Haaaaaaa Haaaaaaa" Ty screamed as pleasure flooded his mind.
And yet he needed more, more than this human soul could allow him to feel. He needed to fully become a demon.
And so he let the mist in.
"HAAAAAAAAAAAAAAA" He screamed as his powers went overboard. He instantly started growing stronger, his form exploding in muscles. His biceps getting as big as beach balls now. His legs looking like tree trunks and this abs now reaching a full 8 packs.
"MOOOOOOORRRRRREEEEEEEE" He quickly grew so tall he hit the ceiling. Still his form wouldn't stop growing. And so he burst through his house's ceiling as he grew up to 20ft.
"RROOOOOOOAAAAARRRRR" He screamed as two huge demonic wings burst from his back, big and strong enough to carry even his gigantic body. Dustin and Mark looked in awe from the remnant of their home as their new lord furiously jacked off his now 8ft long barbed dick.
"I AM YOUR GOD NOW!" Ty roared as he unleashed gallons and gallons of demonic cum on his old house, drenching the two demons.
