My mistress made me Bi-Sexual

My first bisexual experience was one to remember, as it had all the ingredients to make you hot just thinking of it. I was forty-three and very sheltered, married to one woman and no other lovers and no dating since I was a teenager, I was a prime naïve toy for someone to use. Along the way of my marriage many troubles beset us and I began to wonder about what was in the bedroom may not be what I needed.
So I placed an ad on the Internet to meet people, and I meet this lady, she was a bit younger than I, and the horniest thing that I have ever met, and could she cum. It was like a river when she hit her peak. The first day we met she stripped me naked and took me to bed. I loved her breast and ate them eagerly as if they were two cocks and I was sucking them. Her large body was so sexy to me, you see I love a woman that is classified as a BBW. She was that and I adored her, I kissed her ass and ate her pussy with much glee. Then as the weeks passed I became her sexual servant and slave, willingly.
One day after a couple of months I got an email from her asking to meet the next day. When I got to her apartment I was in for the treat of a lifetime.
She knew the week spots on my body already and she would use that knowledge to completely take me as a slave. I walked in thinking of her but once I got there the real sex started. She was waiting by the door wearing a blue terry cloth robe and nothing else. It was untied and partially open as she greeted me with a big wet kiss and as our mouths melded into one her hands began to open my shirt and then she caressed my breast. She knew that those two objects were toys and made me week in the knees when touched, so as I panted from her playing with me she slowly guided me back into her kitchen. At the doorway, she stopped her fondling long enough to produce a blindfold and then encase my eyes with it. Then she led me over to her table. Once there she pulled off my shirt and then unbuttoned my jeans and slid them down, after my shoes were removed she pulled my briefs down and took them and my pants and socks off one leg at a time. Then she leaned me over the table and began to fondle my ass, and as she did I felt a liquid, cool and tantalizing, introduced into my asshole. Then she shackled my wrist and bound them to the table legs and did the same to my ankles. I was harder than a hammerhead as she sweetly cooed into my ear, “Now that I am your Mistress I want to make you my slave boy and girl.”
“Anything you want Mistress, anything at all,” I said as she rubbed and tweaked my right nipple.
“First I have to plug your hole and expand it before you can take what I have for it,” she said as she giggled.
Then she inserted a butt plug into me, she slowly slid it in place but as she did she told me, “I want you to relax your ass and take it all in. After a little while you will learn to love it. Now I am going to leave this in you for an hour and while I am gone you will remain here naked and bound my pet.”
With that she kissed me deeply then left, I heard the door close and I was excited from the petting and from the fact that here I was all alone in a strange place naked and being done like I had dreamed of.
A little more than an hour passed and when I heard her come back in my heart raced. She walked slowly into the kitchen and as she did she told me, “Now my slave I have a surprise for you.”
With those words she unleashed me from my bonds and took me by the hand and led me into her bedroom. Once there she guided me to the bed and had me to bend over the bed at the foot as she slid on and around in way that brought her hot wet pussy to my lips. She removed my blindfold and as she did she pushed my head into her cunt. I ate her like mad, and as I fingered licked sucked and toyed with her lips and hole she began to pour her hot wet goodness into my wide open mouth. Her climax was loud and long and as she slowly began to calm herself I felt another hot gush of moisture begin to emerge from her.
“I am pissing on my slave and you will eat me and drink me, won’t you.” She commanded.
“Yes,” I blurted out as I lapped and licked and was flooded by her piss. As she slowed to a tinkle I engulfed her pussy and began to suck and drain it from her, and she came again right then. Once she was satisfied she pulled me by my hair towards her breast and commanded me to suck her while she relaxed, as I did I felt a strange hand touch my ass. I started to look away to see who it was but she pulled my mouth back to her as then two hands began to squeeze my tight ass. Then the plug was removed and my mistress took my balls into her hands and began to fondle them and squeeze them and toy with them and as she did I felt a cock enter my ass. The man was not small by no means and as his meat filled me I gasped then moaned and then began to suck her again, but she stopped me as this man began to ride my ass harder and faster. Instead she swung her body to watch fully and as she took my head in her hands she told me, “Now slave you are my male toy and his bitch.”
My mouth dropped open as I turned to catch the face of a big black man. He was pumping me like there was no tomorrow and it was then that I saw the other man, a white man in his mid fifties was naked and moving towards my mouth with his eight-inch cock. I was already opened for it without even knowing it and as he slid it into my mouth, my mistress called out, “Fuck him make his mouth yours and then make sure he swallows it.”
The pair rode my open holes for almost twenty minutes before the black man blasted deep inside my asshole with his load of hot cum. As he pounded my ass for the last few strokes he flipped it out and squeezed droplets onto my ass, which my mistress lapped off me. The other man was riding me even more vigorously than before and as he came, he grasped my head in a way that would not allow me to pull away. I almost choked on his load, but as the seconds passed I began to swallow and enjoy it.
Then as the pair released me onto the bed, my mistress told them, “Now we must continue the transformation of my slave boy into a slave girl, making him lick both of your dicks hard again and then having you change places. While you do that I will jerk his dick off onto my tits to serve him as dinner.”
The men were happy to do what she told them too and as I licked the black mans dick first then I sucked it the other man got jealous and jumped in and made me suck him hard again first. All the time my mistress was jerking me off and when I exploded on her breast she kept her word and forced me to lick myself off them, Seconds after began to suck the black man to a harden state, the other man inserted his dick into me with me laying on my back. The pair began to pound me again and when they gone another thirty minutes they both sprayed me in my ass and mouth with their got cum. My mistress told them both that anytime they wanted me that I would be theirs for the asking and then she told me that soon she would be needing a new man in her life because she was going to turn me into a girl. Stay tune and I will let you know how she did it.
