On a packed train, I spotted an ultra-beautiful woman with massive boobs that were obvious even through her clothes. I cornered her from front and back so she couldn't escape, then pinned her arms. When I bared her chest, out came incredibly sensitive special-erotic nipples. Just being seen made them rock-hard, and a light touch made her twitch. As expected, those super-sensitive erotic nipples were licked, sucked, and developed. She was pounded with mind-blowing pleasure, turning into a lewd body that climaxed over and over again. Her pleading, "Please abuse my nipples as much as you want," was irresistible.
