The train's rhythmic clatter echoed our heartbeats as I pushed her against the window, her breath fogging up the glass. Her sari bunched up, revealing her toned legs, her skin glistening with sweat. I traced her curves, my fingers slipping into her warmth. She gasped, her eyes fluttering closed, her body undulating against mine. Our 3D encounter was a dance of lust and desire, our bodies moving in sync, our moans drowned out by the train's roar. As we reached our destination, our bodies were slick with sweat, our hearts pounding, and our encounter etched into our memories.
