(Legit Taboo) My step-mommy and step-daddy have been in the cuckold lifestyle for quite some time. They really got into it once I went off to college. step-Daddy absolutely loves it. He loves driving her around to fuck men, getting her ready for her dates, shopping for her (them), just all of it. As long as he gets to hear about what they do to her, and of course clean up their cum. I finally graduated college and moved back home to find work, so step-mommy invited me over to dinner to catch up. After dinner and some small talk I basically tell her that I was a bull for my professor and her husband while I was away, and that I can't find anyone locally to satisfy those needs. I then slyly mention that he is a member of a group that helps link up bulls and cuckold couples. It turns out, that she have been corresponding, and sending tons of photos/videos to ME on that page. Once I makes this knowledge known, I demand that step-mommy takes off her dress, and explains to her that I am now goirng to be her bull. After some inner turmoil, she accepts it, she loves that I am so stern and know exactly what I wants. So we go to the room, and prepare a giant load for my step-daddy to get to clean up. Now step-mommy belongs to me, every single hole.
