I discover my stepsister pleasuring herself and seize the opportunity to penetrate her depths

I stumbled upon my stepsister masturbating and seized the opportunity to explore her. She eagerly welcomed my throbbing member, skillfully pleasuring it before allowing me to plunge into her depths.

I had always harbored a secret desire for my stepsister, her luscious curves and inviting ass a constant source of temptation. As I entered the bathroom, I caught her in the act, her small tits bouncing as she pleasured herself. I couldn't resist, my monster cock throbbing with anticipation. I approached her, my intention clear. She hesitated, her eyes wide with surprise, but when she saw the size of my manhood, she knew resistance was futile. I took control, my shaft plunging into her tight depths, her moans of pleasure echoing in the room. The sight of her big butt bouncing with each thrust only fueled my desire, driving me to take her harder and deeper. The climax was explosive, a testament to the forbidden nature of our encounter.
