My girl and I used any bals. Ping-pong, golf, egss from kinder surprise. Timer egg is superb You turn it, don`t look for how long time is set, put it in to pussy and wait for ring and vibrations. Of course cell phone. Best was when she hide it inside and have it for few hours or whole day. When she forget about it I ring to her. She loved it. Even jars can be a god toy. red bull can, small bottles, TV remote, PC mouse if only fit in You, fruits like apples, lemons, banana. Pussy can swallow everything if only that isn`t sharp or to big. You must only wath to not hurt Yourself. She even swallow keys to my car
