If you put both hands together to make a circle, it's easy to complete the hand. I was surprised when I put a chi ●● in there! It's like a vagina, no more? The swell created by free hand pressure. It feels so good that I can't stop! One of the attractions is that you can enjoy it in various postures. Stand up and sit down, cowgirl in missionary position, back ... You can enjoy it infinitely depending on your ingenuity!
