Opening the gift Sir sent me, the card reads...I want you to put this inside you and keep it in all day. It will take effort on your part, but the satisfaction it will give me is your reward...I open the box and in it is a single violet ball that has a pull cord attached to it. The material is soft and the ball is weighted. I slip it inside me and strain to keep it in by flexing my PC muscle. Wanting to please Sir, I keep it in for the day and I am erotically aroused knowing that I have it inside of me.
This silicone BenWa ball is double walled and internally weighted for subtle vibrations as the inner ball rolls within the outer ball. The silicone material is phthalate-free, allergy safe, and perfect for long-term wear. With regular use, you can experience heightened arousal, greater tightness, and better orgasms.
