Ty grinned at Dustin, "You thought my dick stretching was hot when I was Mr. Fantastic..." he waved his ass at Dustin, "Care to try out my other stretchy bits?"
Dustin laughed, he had thought Ty would make a pain of himself with his new stretchiness, this was MUCH better. He grabbed Ty's hand and took off down the hall, both of them laughing as he stretched Ty's arm out in front of him.
They found an unused storeroom and slipped inside, quickly shedding their clothes to make a soft spot on the floor. Dustin growled at Ty, "So, you want to shake your ass at me, do ya Mr. Stretchy? Better follow through on that!" And he leaped on Ty, playwrestling him to the ground, already rock hard, "I'm gonna take that stretchy ass, Ty!"
He grabbed Ty's butt and dove in face first, eliciting a moan from his friend. Ty's butt was clean and musky as Dustin worked his tongue into the puckered hole, preparing it for further intrusion.
Above, Ty grinned, Dustin wanted into his ass, did he? Well, he'd give his friend exactly what he wanted! This was gonna be funny as hell!
He relaxed his muscles and imagined his asshole stretching. Dustin, unwarned and unprepared, was pushing on Ty's ass at that moment. Ty's asshole spasmed open and stretched, sliding right up and over Dustin's head!
