Messalina went about her duties, tending to her master's villa outside of Rome. She was captured during the Roman legions' campaign in her homeland at the age of 5. Brought back to Rome and sold as a slave, she has known nothing but a life of servitude. As she grew older her beauty made her a prized possession of her master, the Roman general Maximus. He soon found uses for her beyond cleaning his floors.
Now at the age of 20, her large breasts, dark skin, and perfectly sculpted body have made ever more desirable among both the Romans and the slaves. She's already mated with several dozen lovers, both willingly and unwillingly. For years she has been forced to serve the men at her master's parties and participate in the resulting orgies; where her virtue would be violated, more often then not by several different men and women. She knew that the master saw her as a sex toy for him to use and show off at parties. Sometimes she wouldn't mind, having worked herself into heat and wanting it badly. Other times she could barely get herself wet enough to take cock.
She can still remember the party three days ago. The men and women commenting on her body like she was some object to be admired. Then the shame of being commanded to strip by her master and knowing that she had no choice; that her body was about to be used by everyone at the party. Messalina still remembers the dread she felt at the knowledge of what was about to be done to her as she removed her garments. The guests then commented on her features like they would those of an animal they were considering buying. They openly commented on her physical attributes; often while she was performing sex acts for them. She was the party's adult entertainment.
Everyone had a go with her that night, even the women. Several husbands and wives had taken her, making her suck the wife's cunt while the husband mounted her from behind. She had to participate in an orgy of several women and men. Women would grind their cunt against hers, often while the rest of the guests watched. Men would mount her from the front and from behind. By Messalina's count, 14 men had filled her cunt or ass with their seed that night. Even three days later her cunt was still sore from all the cocks she had to take in it.
She is no less safe outside those horrid affairs. The master's son, Domitian, had all the vigor of a young, aggressive Roman legionnaire. She was his favorite and when he was home, like now, she was commanded to fuck him every few hours to keep him happy. At least he knew how to make it enjoyable for her and his body was so good looking that she'd get wet at the mere sight of him naked. He just did it to her a couple of hours ago when she went to wake him in his bedchambers. He grabbed her arm and dragged her into the bed. She didn't try to resist. If she did he'd overpower her, use her body for his pleasure, and then punish her for her disobedience.
