Sisters test subject

My sister is a domme, she's into bdsm with guys and she's had that for a while. And for about a year I've been her test subject, to try things out on that she'll use on her boyfriend(s). So she ties me up, and she always wears a tight black catwoman outfit. The sort of things she does is beat me, choke me, finger me, deepthroat me (with strap on) and mostly whip me and cane me etc on my ass. Sometimes she spits in my mouth. One time for fun she put some of her boyfriends cum in my coffee and forced me to drink it. She won't fuck me tho, she only fucks her boyfriends. She classes me as her "home slave". I basically have to do anything she tells me and give her anything she wants or she'll expose what she does to me to everyone. I'm ok with that because I love it. I'll probably never get a girlfriend but at least she will carry on with me

  • I wish i could have a sister like her

  • You got to fuck her sooner or later you candy ass

  • I'm not allowed to do anything masculine, it's one if her rules. I can't fuck her or get a blowjob or anything, and I'm not allowed a girlfriend anymore. She told me I'm allowed to suck her boyfriends dick but that's it, otherwise just her test subject and I like it tbh
