As He watched the Hedgehog thrive, Looking as if He was in agony, Tails smirked as he walked forth and grabbed his erect dick. He stroked it fast, Not fearing orgasm as He looked Sonic in the eyes. "So, Sonic, You like my New invention?

"T-Tails It's uh Great," Sonic responded with Haste, Huffing and panting as fast as his foot tapping. He grunted as His cock throbbed, "C-Can You please take it off now? I-Mmn!~...W-Wanna cum...!"

The invention Tails made recently, The D-Nile! It was a little ring machine that halted orgasm and Kept you on edge for sexual pleasures~ Sonic was a test subject to it, In thanks for staying with the fox, As His Shack was Out due to those creatures inhabiting it. 

The Hedgehog just couldn't decide between liking or hating this at all~

Anywho, Tails was in deep thought to that question. "Hm...Nah. Think of this as payback, and I haven't gotten my turn Yet~"

And Sonic pleaded, trying his best to control his moans. "P-PLEASE Tails! Ohh, F-ffffFuck!~ I-I'm sorry-"

...Wait, Did He say TURN?

before Sonic knew it, He was bent over. His surprisingly plump ass was exposed to tails, who lubed up his dick. He'd happily prod Looking at Sonic as so, "Fuck Sonic...I wanted this for so long...finally~"

He would then slide His shaft inside, Relishing in the warm tightness Sonic's ass had to offer, Before beginning to thrust. Tails Kept up a Good pace, Bottoming out in sonic well with His balls Hitting His blue ass. 

Meanwhile Sonic thought he was on cloud Nine, with the thrusting at his but, The ring bringing him to the edge of pleasure again and again, He rolled his eyes up to the ceiling with a happy expression.

Soon Tails became vigorous, Holding tightly as He plowed Sonic's ass with no restraint. The room was filled with each of their moans and whines, a Hot scent of sex trailing forth.

And with one last buck, Slamming all the way in...Tails came. To Sonic, It was like an endless flood of cum flowing, Rope after Rope of Fox seed filling Him. It made him whine for His orgasm.

Pulling away, Tails first instinct was to Kiss the hedgehog on the cheek. "E-Excellent, Hah...t-test Sonic, It's within good numbers...hah...Fuck I need a break~"

"B-But Tails w-What about me??" The hedgehog reminded. T-Taiiils-Fuck~!"

The fox just looked back at Him as he got up and began to walk out. "P...Punishment~"

"T-Tails? TttaaaaaaaaaaaaAAAAaaiiiillllllss~!"

And with that, Tails walked out of the room to go to his kitchen to get something to drink. Juice? Water? Milk. Eh,

He had all day.
