Sneaky Stepdad Discovers Son's Secret Fantasy: A Forbidden Family Creampie Adventure

The humid bedroom air smelled of musk and old paper as Mark, the sneaky stepdad, read his son's diary by candlelight. His eyes widened when he saw the words: 'I dream of your cock inside me.' Heart pounding, he crept to the teen's room. The boy was asleep, shirtless, chest rising. Mark slipped in, the sheets rustling softly. He grabbed the teen's hip, his large hand gripping tight. 'Wake up,' he whispered roughly. The boy jolted awake, eyes wide with fear and arousal. 'Dad?' he stammered. 'Shut up!' Mark growled, pushing him back onto the mattress. He straddled him, his big cock throbbing against the teen's thigh. 'Take my cock deep!' the boy begged, his voice trembling. Mark laughed darkly, sinking in slowly. The wet squelch filled the room as he bottomed out. 'Fuck me harder!' the teen cried, arching his back. Mark grabbed his hips, pounding rhythmically, the slap of skin echoing. Sweat dripped down their bodies, mixing with the salty taste of lust on their lips. 'Cum inside me!' the boy screamed, his eyes rolling back. Mark roared, erupting deep within him, filling him with hot seed. The teen gasped, feeling the warm cum spread inside his belly. They lay there, breathing heavy, the forbidden act sealed in silence. The diary's secret was now a reality, binding them in a twisted, erotic bond.
