From Pipedream comes the Fetish Fantasy Ben-Wa Balls. "He pushed my legs apart giving him full access to my pussy. I gasped as I felt him push something cold and round into me. 'What are you doing?' I asked breathlessly. 'They're called Ben-Wa balls' he said, sliding another ball into me. He helped me to my feet, and I gasped again as I felt the balls move and bump against each other inside me. By the time I was standing up my breath was coming in quiet gasps, and my nipples were hard as pebbles beneath my dress."
