On your asscheek, there is no effect...yet

You whimper as you feel the brand sear the flesh on your asscheek, there is no immediate effect that you can determine. After the brand is cleaned and wrapped, and you are emptied of cum, you are led to a wooden building and tossed in, there are a plethora of races in the slightly cramped building, every is given food and water as day turns to night. One of the older slaves comes up to you as the rest of the slaves are asleep, "I see you have a brand on your butt," he says quietly, "I would avoid doing anything in the surrounding area" the old man walks back to where he came from and lays down.

You spend two days in the pen, nothing else happens until the centaur calls for you, "we need to keep up appearances, so I need you to use your mouth..." She seemed a bit agitated, you get under her and come face to hole with the monster that ravaged your ass two days ago. The first thing that hit you was her smell, it wasn't unpleasant. Her cock was already leaking pre, you hesitantly stuck your tongue out and licked it up, it was sweet and salty. The centaur cleared her throat, you were taking too long and people were beginning to stare, your head was swimming.

What you didn't know was the air you were breathing was filled with her pheromones, making you open to her suggestions, "just put it in your mouth" she whispered to you, which you did get the head in your mouth, you were having a bit of trouble getting any more of it so she decided to help you, moving forward until you were looking up at her belly, she used her weight to **** her cock down your throat, your gagging only making her cock shoot precum, she pulled out of your throat, allowing you to breathe, then she went back down, starting a slow rhythm.

You couldn't ignore your own rock hard cock and you started stroking, her thrusts sped up as your gagging stopped and her climax closed in, yours following right behind, she filled your stomach with her load as your own spurt out under her, she pulled out of your throat and turned around to see your cum on the ground, "now I have to put you in this before we leave" she produced a chastity cage and locked your softening cock in it, then strapped you back into the harness before pressing her still hard and cum covered cock to you hole.

You moaned like a slut as she plugged your ass again, you felt every bump and vein on her cock and you experienced nothing but pleasure, the brand glowing briefly.
