As the incestuous nature of these desires grew stronger, I couldnt help but imagine the taste of his thick cock, thrusting deep into my wet, slender pussy, filling me to the brim.The thought of him using me like just another object to fulfill his lustful needs only intensified my desire, driving me deeper into a frenzy of pleasure.Our bodies meshed together perfectly, their movements synchronized like a wellrehearsed dance, leaving us both breathless and wanting more.He slowly traced his fingers across my sensitive clit, teasing me to the edge before plunging his hard member inside me.My moans of ecstasy echoed through the room as he pumped me harder, the heat of our combined desire threatening to consume us.I bit my lip to stifle my screams, barely able to breathe through the sensation of fullness coursing through my veins.Every stroke was met with equal passion, his body pulsating against mine as we reached new heights together.My heart raced as I gazed down at my mother, watching in horror as my stepbrother took advantage of her trusting nature to satisfy his own twisted desires.It was like a dagger to the heart, and I couldnt stand idly by without intervening.With anger coursing through my veins, I grabbed my stepbrother, pulling him back from my mother.His eyes widened in shock as I thrust his own cock back into his face, the force sending him toppling back onto the bed in disbelief.I straddled him, grabbing his hips tightly and pounding him mercilessly as I drove him to submission.He writhed beneath me, unable to resist the power of my seductive gaze.My stepbrothers orgasm was swift, and I relished every second of my victory, rubbing my hand over his throbbing member as he came to climax.With a satisfied smile, I rose off of him and turned to my mother, who stared blankly out into space as if she were already detached from the reality of what had just occurred.I shook her by the shoulder, Look at him! He just came all over himself! Well go away now, dont worry mom.She simply nodded, and we left the room as quickly as we had entered it.
