Filming a personal video with my stepsister's large natural breasts leaking semen

I was in my room, filming a personal video for my boyfriend, when my stepsister walked in. She's a beautiful 18-year-old with big, natural tits and a curvy, Colombian body. My boyfriend loves her, and I love to watch her. She's always up for some fun, especially when it comes to dirty talk and domination. This time, she was so turned on that her breasts started leaking semen. It was a sight to behold, her big, natural tits covered in cum. I couldn't help but stare, my eyes drawn to the sight of her body covered in her own cum. It was a hot scene, one that I knew my boyfriend would love. I quickly snapped some pictures of her, ready to share them with him. But for now, I just enjoyed watching her, her big, natural tits covered in cum.
