I'm in a cuckold relationship and for the most part me and my GF have kept it quiet from friends and family except my sister who caught us red-handed.
Unfortunately for us my sister decided to drop by my apartment one day our bull was over, thinking we weren't home since she has a key. She let herself in and found my GF bent over on the couch with her black bull pounding away doggy, her ass beat red. I was kneeling on the floor (my usual place) in a pair of my panties and leggings around my knees (I'm a full sissy when her bulls are over). I had already cum twice on the floor in front of me and had made a mess that was pretty obvious, and my third load was happening when I looked over and saw my sister standing there with a shocked look on her face. Try as I might to stop it but I shot my third load on the floor again.
We both just sat there shocked for a minute, then my senses came back and I managed to get the bull and my GFs attention. My GF jumped to cover up as my sister muttered something about coming back later and left shutting the door.
