I have been serving my Mistress for a few years now. Its been a bit of a roller coaster for us both but it's been a fun one. I love her and I'm completely devoted to her.

She makes me do a lot of humiliating acts like having sex with dirt, pissing over myself, sleeping on the floor, dressing up, exposing myself and even using my mothers toys. All while she holds blackmail over me. She has everything I have ever done saved and she has my mothers contact too. Which is used to keep me in place. Occasionally exposes me on her MeWe account too for everyone to see. I worry she will get tired of that and start exposing in other places as I'm already very exposed on there. But I know she likes when I worry and that's enough for her.

She tells me to live in fear and I do.

Mistress knows I have a bit of an incest fetishs and encourages it too. Especially when it's about my sister. But one day I stupidly mentioned my sister also have a kik account. And of course without a choice, I had to hand over the username. And from then my relationship with my Mistress reached a whole new level. I thought it would be like the other contacts she has of me. Used as a threat and nothing more. But this time my Mistress contacted my sister. She acted like she found her username when browsing and just happened to find her. And to my surprise my sister started talking back to her and our becoming good friends. Im not sure how much they talk and what about. But I know they discuss about their jobs. She's told her that she's a professional domme and my sister has seemed interested in learning about this.

My Mistress has openly talked about humiliating things I have done for her. Like the time I went out in public and fucked a dirt whole in the ground. I get to see my sisters reactions all while not nothing it's actually her brother doing them.

Mistress talks about how she's going to either turn my sister into her sex slave. How she pictures both of us naked on all fours, worshiping her feet, eating her pussy and ass and doing sexual acts for her.

Or train her up as a domme. Which I'm very nervous about. As Mistress has talked about the idea of having me get a new kik account. One my sister doesn't know about and putting us in a chat together. Where my Mistress and my Sister will dominate me all while my sister has no idea its actually her brother she's having sexusl acts with.

All of this makes my heart jump and my body sweat and shake in fear. I think I know I'll eventually get exposed to my sister but I don't know when or how. They have been talking for months now. And I don't know my dommes end result. She has been very quite lately on their chats.
