Mark's cock throbbed inside Lena's spasming asshole, her walls clamping down like a vice as aftershocks from her orgasm rippled through her curvy body. Sweat slicked her flushed skin, her big tits heaving with each labored breath, red marks blooming from his slaps. The train's dim lights cast shadows over the sleeping passengers, their oblivious snores a thin veil over the raw frenzy unfolding. He felt her tremble beneath him, her tight pussy still dripping from his fingers, but he wasn't done—not by a long shot. With a guttural grunt, Mark yanked his thick cock free from her ass, the sudden withdrawal making her hole gape briefly, slick with her juices and his pre-cum, before it clenched shut in protest.

Lena gasped sharply, the emptiness hitting her like a punch, her mid-twenties frame arching off the seat in desperate need. Her brunette hair stuck to her sweat-damp forehead, eyes wild and glassy from the edging high, her adventurous hunger gnawing at her core.
