Three rings and a cuff for fun during sex. Trying out how my cock behaves when I wear these things. The cuff makes my testicles nice and thick in the sack and stretches the sack. So the sac becomes very sensitive and my cock becomes hard - it gets a rubber ring and there is also another one around the scrotum. Simply a great feeling - which would soon make my cock squirt when I moved. I'll test that in a pussy.
