A perfect sound for beginners, this flexible, hollow silicone penis plug is designed for exploring urethral sounding play. Measuring 2.25 inches in insertable length and 10mm at the widest point, it provides safe, satisfying stretched sensations. Apply a generous squeeze of good-quality water-based lubricant to the plug and your urethral opening before slowly inserting the sound into the end of your penis. Its tapered design aids insertion, while the D-ring top stops over-insertion. Made from silicone, this flexible plug is hypoallergenic and flexes with your body to minimise risk of injury. With its hollow design this plug enables the wearer to urinate and ejaculate as usual during wear, enabling long-term wear possibilities.
