Lykos Lobo, my stepbrother, walked in on me peeing and got a wild idea. He grabbed my head, shoving my face into his massive cock. I struggled, but he was too strong. He forced me to suck him off, making me take his entire length deep into my throat. I gagged, tears streaming down my face, as he held my head, fucking my mouth roughly. He came hard, his hot cum filling my mouth, forcing me to swallow every drop. Then, to my horror, he pissed in my mouth, making me drink his piss while he laughed at my humiliation.
