"Wow, Heh. I Look fine as hell~" 

"U-Umm...Thank You?"

As if being Put into some Random place by a mysterious force wasn't weird enough, He wasn't the only one there!

It was another version of Himself, But more Courageous and... Buff.

so Yeah, It got weirder.

He continued to inspect Tails "No problem, I mean Damn," He swatted his hand and an asscheek. It made Tails groan lowly in the process. "That's some fat ass~!"

Tails flushed pink even more. Was he really...that big in the back there? 

Unlike the Buff-Tails, He was slim, Muscleless, and With a firm, Round, Soft, yellow package in the backseat called his body.

Now all the looks he got from his male friends in recent weeks made sense...

"Hey, Wanna conduct an experiment?" Buff Tails suggested. "Since we're in here and all..."

Tails perked up at that. "An Experiment? Sounds interesting!" He smiled. Maybe they weren't so different after all... "What is it?"

He watched as Buff-Tails walked close. Putting an arm around him, He'd whisper softly: 

"If Having sex with yourself...Is Gay, Or masterbation~"

[...]

"Fuck, Fuck, Fuuuck!!" Tails cried out as he felt that hard cock hilt deep inside his ass. His cock twitched with the thrusts that were given to the prostate as His face felt high on pleasure. 

Feeling the dick slowly sliding out got him to pant heavily like an animal in heat. the panting was stopped as the smack was then delivered to his ass, Fast and Hard. 

It stung too. Tails could feel His ass bouncing, jiggling all over as it stung. He also couldn't help but let out a high-octaved moan too. "A-AaaAah~!"

"I'm so cute~" He could hear. Obviously, it was His Buff-Self, Watching him. "Makes me wish I could fuck this ass forever~!"

After that, The Kit would feel the dick sliding back in, going slow at first before changing to a fast pace, Hilting further and Pumping hard, Drilling deep towards His prostate.

Hands were on both sides of his ass as he went deep. The Buff Tails gritting his teeth as he was focused on breeding himself. Tails clenched as a reply, squeezing down on his cock, gripping it tightly to attempt to milk it out of orgasm, A Attempt that would be a success.

As he was dazed from pleasure, Tails didn't exactly know if he came before or after Buff-Tails did. All he did know was that He felt hot goopy fluids of milky cum enter his bowels, Another thing was Buff-Tails' hoarse groans as Tails' own cock started twitching rapidly, His balls clenched, firing off strings of his own pearly white cum on the grass beneath.

Once done, However, It was quiet, leaving nothing but tired huffs and puffs between the two twin-tailed foxes, Buff pulling out and rolling onto the floor, Followed by Regular as they relaxed in the afterglow, trying to catch their breaths...

But soon, once one of them regained the ability to speak However...

"Success."

"Huh?"

Buff-Tails turned his head to the other tails Who said that. "W-What?"

"The Experiment." He simply replied. "Guess we're right on both, it's masturbation..."

He scooted himself close to give the Buff-Tails a quick peck on the cheek, This time him flushing. "And it sure is gay too, Hehe~"
