On an overcrowded morning train, a massive man boards directly behind the slender office lady and blocks everyone else's view. Hidden from the other passengers, he freely crushes and fondles her slim yet full breasts. She says no and burns with shame, but the stimulation still feels good. Held so tightly that she cannot move, she is overwhelmed by his relentless body pressure and climaxes again and again, eventually becoming unable to escape the pleasure of his full-weight pounding.
