Jeff stopped for a minute and pondered it. Even in his BO hazed mind, he knew this was an important decision. Whatever he chose, he would be for the rest of his life. All the rank possibilities shuffled through his mind before he chose one; the nastiest one he could think of.
"Anus. I want to be your smelly asshole, Simon", he pleaded with sincere eyes. Simon laughed, "Are you serious, you nasty fuck? You would choose to be my anus? Alright, whatever floats your boat!".
Simon pulled off his wet, smelly jockstrap and it hit the locker room floor with a wet splat. He stood there in all his naked, hung glory. "On your knees!", Simon barked, to which Jeff complied. "So, Jeff, this is a big decision. If you choose this, you will be my asshole for the rest of my natural life. You will breathe farts, feel and taste my shits push through your mouth, and have smelly anus hairs growing out of what is now your lips. Here, take a good look before you decide".
With that, Simon bent over and pulled his very hairy ass cheeks apart. His puckered anus was shown to Jeff. Jeff moaned at what he saw. It was so dirty, and there was so much hair! Because of all the sweat and hair, Simon had a lot of trouble keeping his ass clean. Jeff would always be tasting shit!
Jeff leaned a bit closer, examining the smelly doughnut that would soon be his whole existence. Simon grinned and let loose a huge fart. The warm gas hit Jeff right in the face. He gagged at the putrid smell. It was so terrible. However, his cock, at full mast, had different ideas. Jeff moaned as he came in his pants from the smell. Jeff's degraded mind told him the answer. Yes. He had to be Simon's anus.
Jeff shoved his face right into the hairy mess. The taste and smell was abhorrent. It was so bad that part of Jeff was horrified, already regretting the decision. The other part of Jeff was extremely turned on
It felt like he was being pulled in. Everything went dark. He could feel his body getting sucked in, his limbs receding back into himself.
Jeff was frightened; he couldn't feel anything! All he could sense was the gag inducing taste and a horrible stench. Jeff realized he felt something! He felt what used to be his lips. They were puckering, pushing out. He felt them tickle as he felt thick hairs grow out from them, curling and creating a mess. He realized his lips were Simon's anus! His mouth was his asshole! He tried to scream, but all that happened was a very soft fart. The rancid gas passed through his lips, making it taste and smell even worse. He didn't have a tongue, but he could still taste. It tasted just awful! He slowly regained his sight, and saw it was blocked by 2 very hairy ass cheeks. He tried to move any part of his body, but found he couldn't. He was just a smelly hole; nothing more.
Jeff had been extremely aroused, and was almost in a daze when he chose this. Now his mind was a bit clearer; what was he thinking?! He was stuck as a hairy, musky asshole for ever! It was permanent! He would never experience any tastes other than shit, and he would always smell dirty asshole!
"How are you doing back there, bud?", Simon asked jokingly. "Hope your getting used the smell and taste. I have to take a huge shit soon. It should be nice to break you in!"
"Oh no!", Jeff thought. Simon was going to take a shit!
