PR2 Portable 10 Vibrating Silicone Cock Ring For Men

Used it in the morning and honestly felt more awake than after a cup of coffee. Its small, but it does the job well.

Super quiet, which I appreciate. But the strength? Way more intense than I expected. Good balance of comfort and power.

It stretches just enoughnot too tight, not too loose. Comfortable fit and the motor hits the right spot.
