I knew about my son`s cuckold relationship thanks to acquaintances. We all belong to the BDSM community. I was having none of it. Although I had always been very dominant with him, I expected he would behave like a man with his wife, not to let her step over him like he did. That´s why I always spanked my daughter in law, to get her to know her place.The worst part was the identity of the “bull”: a SWITCH (ie, someone who can be both a dominant AND a submissive, depending on the circunstances, therefore, NOT A REAL DOMINANT) whom I have dominated several times at BDSM meetups, without sex. Imagine my frustration when I realized this poor excuse for a man, whom I have had literally kissing my feet, was topping both my son and daughter in law, pretending to be an “alpha male”. So I tried to talk him out of the picture in the next meetup. First, I tried to reason with him, to no avail. Then I used my daughter in law as a whipping girl, but this just turned him on even more. So I appealed to his submissive side just by ordering him to end that relationship, to which he said this wasn´t my business. I threatened to reveal to both of them who he really was. He didn´t respond, so I backed him against a wall, slapped him across the face and had him opening his mouth so I could spit inside. After he swallowed, I touched his boner and commented how aroused he was getting with my mistreatment, as a reminder of his true role. He looked at me a bit scared but didn´t cave in. My frustration grew even stronger when my son told me he was planning to get my daughter in law pregnant from their “bull”. I knew they wouldn´t believe me he was a switch, so I arranged a meetup with the four of us, so they could see it by their own eyes. Upon arrival, I told him I was going to spank him and ordered him to strip naked. After a moment of hesitation and looking to the three of us, he obliged. They couldn´t believe their eyes. Then I did the same to my DIL. Then I took the two of them, broken and naked, to my bedroom and told my son to wait outside. Once inside, I sat on the bed and told my DIL to sit in a chair, kiss my feet and take off my heels. While she did, I fondled her body (I´ve always had a bi streak) and taunted her about how I had “her bull” wrapped around my finger now. Then I took off my dress and underwear and told her to lie on the bed. She looked at my naked body with a mix of jealousy and fear and shook her head. She knew what was coming. For a moment I thaught about ordering the “bull” to restrain her for me, but I didn´t want any more physical contact between those two, so, instead, I said to him “Don´t intervene, and don´t masturbate, just sit there and enjoy, this is between she and me, did you get it?”. My DIL couldn´t believe when he just answered with a very submissive “Yes, Ma ´am”.Despite being younger, she is a petite woman, so it was easy for me to push her to the bed and climb over her. She tried to resist and, to her credit, gave quite a good fight, but she was no match for me. I managed to pin her wrists against the headboard, plant a kiss on her and trib her to orgasm. Then I threw her, had her lying flat on her back and sat on her face. I ordered her to lick me to orgasm, which she did. Meanwhile, I taunted her about how much she enjoyed the tribbing and how much “her bull” was enjoying the show. When I came, I told her to sat on the chair and watch how submissive was “her bull” on bed. I had him handcuffed to the bed and told him he couldn´t cum without my permission, to which he only responded “Yes, Ma ´am”. I straddled, scratched, slapped, spat, smother and had him begging to be allowed an orgasm. He obliged like the good submissive he actually is. When he cum, I had my DIL clean up the creampie from my cunt, something she did with my son as part of their cuckolding practices. When she was done, I told her to spit the cum on “her bull”`s face. She did it without hesitation and with a lot of rage. I was having the time of my life, so I told her to feel free to take out her frustration with him, just like I did. She straddled him and spent a good while slapping his face, body and balls and calling him a wimp and a fraud. As you can imagine, I encouraged her to continue. Not only she ended that fake relationship, I ended up turning him into the cuckold he actually is in the following months, having him watching me with other men while he only watched, and performing degrading acts just like he did to my son. And then I dumped him, too. These days, either he performs as a submissive or switches with other fake dominants like him. No one has taken him seriously as a dominant since that day. 

The wife’s been out of town for a couple of weeks so it’s just been me and my 25 yo DIL. Was stroking one out this morning when she walked right into the room just before I came. As I was looking at her, she froze as she was looking at every squirt of jizz as it left my cock. After a few seconds, as I lay there with my chest and stomach covered in cum, she asks me if she can have the rest of the bagel bites.
