All your life you've had to look after yourself. Life was hard, but you had your talents, and you got around. You survived even if it required breaking the law and putting yourself first. Your few friends got caught, your partners being sloppy in their trade and one by one being locked behind bars. This is now your fate, the guards got a lead, an old friend sold you out. You were walking down the street when you were pinned to a wall, roughly cuffed, then led away.
Your crimes were tallied, and the decision was made. Life in prison, no more freedom, no more of your life. Unless you agreed to the new 'rehabilitation' program that was offered. Any option sounded better than prison, so you quickly accepted. You were led out of the jail, escorted by guards to the 'Wayward Tavern'. The situation was explained to you on the way, this tavern houses up and coming adventurers looking for partners. Prisoners who signed up for rehabilitation are given to the adventurers to be their companion, then they set off. Didn't sound too bad, life on the road with someone you'll just ditch later.
But there was more to the story then you thought. The guards undid your bindings as they pushed you through the door, you stumbled inside and smelt sweat and sex. All the 'adventurers' in the room where in the nude, they eyed the prisoners hungrily. You had a bad feeling about this, and that feeling turned out true. You spotted an orc walking up to a prisoner, his dick dripping pre on the floor. You hear him proudly exclaim "THIS ONE BELONGS TO YAOR'TERH, PUNY WEAKLING TO STRONG ORC!" as he grabs the back of the man's head.
The man is forcefully pressed against the Orcs shaft, and in a few moments, you see the man tense. You hear the sound of tearing as the man's clothes burst to reveal green skin and muscle. The green consuming the man, his face becoming monstrous as tusks emerge, the tusks themselves being the perfect distance to cushion the orc's cock. The orc smiles happily as the man changes, his meaty arms groping the transforming human. Finally, the two cum, the previous man now a new orc. His muscular and hairy form matching his companion.
Cheers erupt from around the bar as the orc and his partner break into another kiss. Your eyes dart around the room as you see adventurers looking at you. Your gut sinks as you know one of these adventurers has set themselves on you.
