It would be best to read chapters 1 and 2 to understand how I got into this mess. This chapter starts just after my neighbor that is blackmailing me forces me to lick her pussy (my first time).
"You like the taste of my pussy don't you slut?"
"Yes Mistress."
"That's a good thing because you are going to get to taste it a lot. Now, follow me."
I followed Gwen to her bedroom. She walked me to the side of the bed and then told me to climb onto bed and get on my hands and knees, facing the bottom of the bed. She walked around to the side of the bed, to the night stand and pulled out two lengths of rope. She tied a small loop in one end of the rope and slid the other end through it and slid the larger loop she created over my left wrist. She tied the other end of the rope about half way up the bed post. Then she did the same to my other hand leaving me on my knees, bent over with my arms stretched between the two posts. As I said before, my tits are huge and with each little movement, they were swinging heavily beneath me.
Gwen stood at the end of the bed and reached down and at first, gently massaged each one. The longer she rubbed them the harder she squeezed them.
"Is this how you let Justin play with your big titties?"
"Yes Mistress."
"I'll bet he liked them."
"Yes Mist..."
Gwen squeezed my left tit roughly and slapped the right one hard.
"Aaaahhhhhh!" I screamed.
"Oh, my little Slut, you can't fool me, I know you like it rough. I saw how you liked it when Justin was squeezing your big tits. I'll bet you like it when I slap them don't you?"
Before I could say anything, Gwen began slapping my tits, one, then the other, several times. They were swinging wildly beneath me. She stopped for a moment and then slapped them again, this time making sure to hit my nipples. Each time it sent incredibly powerful and painful shocks through my system. It hurt, but it also felt good, a feeling I can't explain. My nipples were growing harder and my pussy was responding by leaking my girl cum down my thighs. I couldn't think straight. I could have tried to get my hands out of the loops and fight her but I didn't want her to stop. It was a confusingly powerful feeling but it was a clear message that I wanted what she was doing to me. I wanted her to use me.
Then she started asking me questions that she gave me no time to answer.
"I bet all the boys you dated in college loved playing with these big slutty tits, didn't they?" and "I bet your boyfriends all wanted to fuck these big tits and cum all over them didn't they?" All the while she was pinching and pulling on my nipples and squeezing and slapping my tits.
I was crying but not because it hurt. I was crying like there was some giant emotional and sexual release. I wasn't happy, I wasn't sad, I just let go and it came in the form of tears.
That's when I knew just how submissive I was. At that moment, I wanted her to use me in any way she wanted. I wanted to be her fuck toy, her cum slut. I wanted her, no, needed her, to make me her slut and I knew that I would willingly do whatever she wanted no matter how humiliating or how degrading. I knew at that moment that there was nothing I wouldn't do to please her. It all happened in an instant. It was like she flipped a switch in me. This was a side of me that I never knew existed.
I think she could tell what I was thinking. I couldn't look her in the eye but I could tell that she was looking at me, seeing right through me to that submissive part of me that I had kept hidden, deep down, out of sight. She knew then that I would be her slut for however long she wanted.
When my mind finally started to focus again, Gwen was still pulling on my nipples, pinching and stretching them and then releasing them. She pulled and twisted them until they were burning and then she would release them and slap them and then repeat.
I was close to cumming just from her torment of my sensitive tits when she suddenly stopped. She walked around to the side of the bed and I felt her hand slide down my back and onto my ass and then to my pussy.
"You are such a slut. Your cunt is dripping isn't it."
"Yes Mistress."
"Do you want to cum Slut?"
"Yes Mistress pleeeeaaasssee, I need to cum." I pleaded as she slid one of her fingers inside my slippery hole.
"I don't care what you want Slut. You belong to me now and you will cum when I tell you to cum. Do you understand?"
"Yes Mistress."
Mistress Gwen walked over to the closet and pulled a box from one of the shelves. She brought it over to the end of the bed and held it in front of me and flipped open the top. Inside there were three strap-on dildos.
There was a pink one. It was about six inches long and was relatively thin. It reminded me of my husband although I think he has a little more girth. The second was purple and was about eight inches long and was pretty thick with ridges along the shaft. The last one was black and looked to be at least ten inches long and was almost as big around as my wrist.
"Pick one slut. I'm going to fuck you and I am allowing you to pick which one I fuck you with. I will tell you that before we are done, I will use all of them on you and I will fuck you in all three of your slutty holes with each of them."
I looked at the big black one and couldn't image that thing in any part of me. I thought that I should choose the smallest but I also knew that wasn't the one I really wanted. I nodded toward the purple one that was eight inches and pretty thick.
Gwen smiled as I timidly asked for the medium sized dildo. She pulled it out of the box and stepped into the harness.
