I comforted my stepsister as our instructor ravaged her vagina vigorously

I was trying my best to comfort my stepsister after our instructor ravaged her vagina vigorously. She had been crying and sobbing, her body trembling with the intensity of the pounding she had just received. I could see the pain and the pleasure etched on her face, a mixture of tears and ecstasy. As I held her close, I couldn't help but feel a strange sense of arousal building within me. The thought of her being fucked by that massive black cock sent shivers down my spine, making my own cock twitch with desire. I couldn't help but imagine what it would be like to be fucked by such a monster, to feel the raw power of his big black cock inside me. I couldn't help but wonder if he would fuck me too, if I was worthy of such a privilege.
