A quick note. Everything you see in the story is happening with the consent of everyone involved.
At the end of the day, Master Bob and Marsha decided that they would spend some "alone time" to think about all they have done so far and planned to do in the future. Mistress told Master Bob, "It's Sunday evening, why not go home and then if you still wish to continue, you can come back here Friday evening and spend the week end with us. By then, Scott should have received the branding irons and we can have some kinky fun."
Both Marsha and I work at the local library, she is my boss, and she is also the only one that knows I am not a genetic woman. All throughout the week we tried to sneak away for a quick kiss or something a bit more intimate, but for the most part that failed. By the time Friday evening rolled around we were both ready to jump each other's bones.
When the knock on the door finally came, I opened the door in just my normal attire; stockings, garters and heels and nothing else. I invited them in and then crawled to Master's Bob and kissed his feet and then pulled down his pants to kiss his cock. After I did that Becca and Sue took a turn as well. Marsha finished taking off her Master's clothes and then crawled to Mistress and Madame and greeted them by kissing their feet and leaning up to submissively kiss their arses and cunts. While she was doing that Sue and I undressed Master Bob.
Since all of us were already naked when they got to our house and Master Bob was now nude, that just left Marsha who had not yet taken off her clothes. She went to remove her clothes when Mistress said, "Keep your clothes on dear. You have clients waiting for you." With that we all went out to the barn where we saw Travis and Tomas waiting for us. They wore jeans and tight-fitting shirts that really showed off how muscular they were.
Mistress asked, "Do you remember these men Marsha?" She nodded sadly, "I do Mistress. I made a fool of myself when I tried to sucked Travis' cock. I never did get a chance to apologize. May I now please?" Mistress smiled, "Of course dear." Marsha dropped to her hands and knees and crawled to Travis and kissed his feet respectfully, "Sir I am so embarrassed by how poorly I did last time we were together. If my Master would permit it, I would like a chance to make it up to you." Both Master Bob and Mistress agreed and then Mistress said, "Girls let's go inside and give them their privacy. Bob and Scott, why not stay, I am sure you would love to get your cocks sucked as well. Julie stay here in case Marsha needs any help or guidance girl." I quickly curtsied respectfully, "Yes Mistress."
We all went inside, but there really was no privacy. Our Owners had a CCTV system installed all throughout the house and barn. We sat in front of a big screen TV to see if Marsha could show the men how good of a cock sucker she had become. Mistress and Madame sat on the couch, while Becca and Sue rested their heads on the soft thighs of the Dommes that were spread wide.
Marsha went over to Travis and asked, "May I undress you please Sir?" Travis looked at Marsha and seemed to be angry. "Look slut, I am not some lame ass 'john' here, I know all your tricks, just get naked and suck my cock and you better do a better job than you did last time, or I will beat your ass." In just a moment, all 3 of them were naked; Marsha, Travis and Tomas. Master Bob and Master Scott were sitting on some hay a few feet away and could easily hear and see everything happening. Master Scott saw Marsha's husband/Master shift uncomfortably because of the tone Travis used and the threat of violence.
I remember thinking to myself, "Master Bob must be really concerned, his hard cock is shriveled and soft now." I reached up and took his hand and whispered, "Your wife is with a client now Master. She knows what she is doing. Please don't embarrass her by interfering. That will shatter her confidence and ruin everything we have been trying to teach her." Master simply nodded and I leaned in and took his cock in my mouth and soon he was hard again.
Travis reached over and grabbed Marsha's hair and pulled her face to his cock. He rubbed his cock and balls all over her face, leaving streaks of pre cum on her. His cock was huge, 9 inches, and was so hard and black, it looked and angry as Travis seemed to be.
Travis pushed his cock into her mouth and used her face like a hole. He thrust his hips hard and fast. His huge cock pushed down her throat making her gag. In time vomit started to dribble around her lips and dripped down on her tits. Finally, he pulled his cock out and poor Marsha puked all over herself and Travis.
That seemed to enrage Travis and he viciously slapped Marsha's face, causing vomit to splatter all over the poor girl. Once her mouth was free, Tomas pushed his cock inside her mouth and repeated the process. Poor Marsha puked again and she was a mess. Puke all over her face and tits, tears streaming down her cheeks making her mascara run little black streaks. Travis glared at Master Bob and said, "Your bitch better learn to suck better, or she will starve as a whore."
I could feel Master Bob wanting to get up to defend his wife, so I bit his cock. He then brought his hand back and slapped me so hard that I fell down. Tomas laughed and said, "Now you're getting it, that is how you treat white bitches." Master Scott grabbed Master Bob and told him to settle down.
Travis and Tomas grabbed Marsha and pulled her over Travis lap for him to spank her. Sprawled over his lap, the red jewel from Marsha's butt plug peeked out. Travis gave Marsha a severe spanking, causing the plug to push deeper and deeper into her arse.
In the house, Becca looked at her wife/Mistress and asked, "Madame, why are they doing this? Travis and Tomas are always gentlemen, they would never act like that. What is happening?" Madame said, "They are acting like that because we told them too. Nancy and I wanted to see how she reacts to sexual violence. Also, we wanted to see if Bob could maintain his composure as his wife is being abused."
Once Travis was done spanking her she kept her on his lap and called me over. "Get that filthy plug from her ass." It was buried so deep in her arse, that I had to twist it to get it out. As expected, it was filthy. "Go show it to her Master, she him what a dirty whore he is married to."
When I presented it to Master Bob, he kissed the tip and then slowly started to lick it clean. Travis laughed, "I thought as much." Then Travis pushed Marsha on to her hands and knees and put his massive cock inside her nasty arsehole. As he fucked her arse, Tomas put his cock in her mouth and started to fuck her face. There was nothing gentle or sensual about it, Marsha was being raped while her husband watched.
