MIRROR: Download from MEGA I've said before on here that my husband is my slave and our Mistress/slave relationship is 24/7. Where our families are concerned, I am his wife, he is my husband.. they don't know anymore than that.. nor do they need to, but there are rules/practices in place for those situations that my slave adheres to to the letter. Nothing anyone would really notice UNLESS you're into BDSM. So my SIL (my slave's brother's wife) calls me this morning and tells me she needs to ask me something, but it's very personal. Then she just blurts out.. "Do you know about BDSM?" Lets just say there was silence after that for a minute LOL..not a question you get asked often. I just said Yes and she goes on and says that she thought so and asked me if Brian was submissive to me. I ask her why she would think that and she tells me that the last time we were all together at my MILs that she noticed he didn't do anything without looking to me out of the corner of his eye and waited for my reaction, noticed that one word in particular stopped him cold no matter what he was doing, and she also noticed that he always sat at my feet on the floor instead of in a chair (you may think this is an obvious give away, but there are never enough chairs for everyone when everyone is together so someone always ends up on the floor.. its just always him ). She tells me she thinks he is submissive 24/7 because of the things she saw at my MILs. So I ask her why she's asking me these things and she tells me that my BIL has been submissive to her and that they are wanting to make it a 24/7 Mistress/slave relationship but are looking for advice on how to make it work. I can't say I'm 100% shocked because when I first met my BIL 6 years ago I told my slave I thought his brother was submissive and my slave thought if anything his brother would be a dom. Now my SIL wants to bring my BIL and come for a visit next week so we can show them how to make it work 24/7 and what all is involved. I agreed they could come and now must break the news of who/what my BIL is to my slave preferably BEFORE he comes home from work to find his brother kneeling in the living room LOL My slave has always been EXTREMELY protective of his brother, so I'm not really sure how well he's going to take knowing his brother gets whipped, disciplined, and humiliated on a daily basis. Any ideas on how to break it to him gently would be much appreciated.
