Under the cloak of night, I slip into my step-sister's room, my heart pounding with anticipation. The soft glow of the bedside lamp illuminates her husband, sprawled out on the bed, his muscular body clad only in tight boxers. My eyes rake over his abs, my mouth watering at the sight of his growing bulge. I approach silently, my breath hitching as I reach out to stroke his hardness. He stirs, moaning softly as I free his cock from its confines, my own body aching with desire. I mount him, my pussy already wet and ready, and begin to ride him slowly, my tits bouncing gently as I take him deep inside me. We fuck in silence, our bodies moving in perfect sync, until we both climax, our release marked by soft moans and shuddering breaths.
