This story is about my first time getting cucked by my girlfriend. It began with my girlfriend asking me about what kinds of things I was into or what fantasies I had. She already knew about my sissy fantasies but she wanted to know more. A part of me thought she was asking, hoping that my fantasy was to be a cuck. I was too embarrassed to just tell her, so instead I shared a porn video that I was really into with her. The video was a bbc bull fucking a girl while her sissy cuck watched on. My girlfriend acted surprised as she watched the video and she teased my a bit saying “ohhhh so this is what you’re into huh?” I was too humiliated to speak, but the answer was yes of course. Once she found out about my little fantasy, she started teasing me about it a lot more. She started by bringing it up while jerking me off. She would say things like “so you’d like being my cuck? Watching me get fucked by a bbc?” I came almost immediately every time. The teasing evolved more and more and soon enough, every time we would have sex she would say things like “your cock is so small and pathetic, I need a real man to fuck me. Not your little sissy dicklette”. She could tell how horny it made me every time. One day, she asked if I would really ever let her cuck me. I thought about it for a while and eventually agreed that I would. It was always so fun fantasizing about it, but the idea of actually doing it was a whole other thing. I was scared by the idea but so turned on at the same time. We agreed that she would go on dating apps and look for a bull. She said “we don’t have to commit to anything, but let’s just see what we find”. Within minutes she had hundreds of guys liking her and messaging her. We would go through them and pick out our favorites together and she would explain our… situation to them. Once she said that they would get to fuck her, they almost all said yes. After a while, we picked one that we both liked. He was a big strong black man. Like body builder strong. You could tell he was confident just from his pictures. She chatted with him for a while and he was eager to meet up in person. After some convincing from my girlfriend, I agreed to make my fantasy a reality. We invited him over one weekend and planned it out. The plan my girlfriend and I came up with was, he would come in and hangout for a while until we got comfortable. Then we would all go up to the bedroom where he and I would start playing with her and getting her ready. Then he would fuck her while I watched. After that he would go and we wouldn’t talk to him again. But really… that’s not exactly what happened. We invited him over, and while he was on the way my girlfriend pulled out a new chastity cage. She said that she wanted me to wear it while he was here. She caught me off guard a bit with this but the idea turned me on a lot so I went along with it. Now with my chastity cage on my soft little cock, he arrived. He came in and almost immediately my girlfriend was all over him. Sitting in his lap, rubbing his thigh, kissing him on the cheek. It was all happening a bit fast but she seemed so into it, and I was so turned on, even though my dick was stuck in a tight cage, unable to get hard. After a bit, my girlfriend escorted him up to the bedroom where they started to undress. The last thing my girlfriend took off was her panties. Once she did, she came over to me and told me to get naked. Without saying a word I began to undress. As I took off my pants and underwear, my locked up cock was revealed and they both started snickering. She turned to him and said “see! I told you I would have his little dicky locked up!” She then held her panties out towards me and said “here. Put these on sissy boy”. Again I did as she said. I was so humiliated and turned on I couldn’t even think. I just did exactly what she told me. After that, I sat down on a chair in the corner and watched as this man took his massive BBC and stretched out my girlfriend in ways that I never could. He brought her to orgasm after orgasm while she screamed and told me how “his dick is so much bigger than my little cucky cock”. The whole thing was so humiliating but I had never been so horny in my life. After what seemed like hours, he pulled out and blew a massive load all over my girls ass. She called me over and told me to lick up the mess. Again doing as she said, I liked up our bull’s thick load from my girlfriends rosey red ass. Our bull laughed watching me and took some pictures while I cleaned up his mess. Once I was done my girlfriend turned around and said “good cucky! Now for your reward!” She took off the key that she had wearing around her neck and unlocked my cage. She took my cock in her hand and began jerking me off. Almost immediately I got hard and I was ready to cum. I’d never been so horny in my life! She asked our bull to come over and she held his cock about an inch away from my face. She continued jerking me off while saying “you see this cock baby? This is a real man’s cock. Your little sissy clit could never fuck me like he can. That’s why his cock is covered in my pussy juices and yours is only getting my hand.” Almost as soon as she finished that sentence, I blew a load all over myself. She gathered up all the mess in her hand and fed it to me saying “a good cucky always eats cum. Every last drop.” I’d never cum so fast or so hard in my life and I knew that I needed this feeling again. That same night we started looking for more guys and started planning our next time!
