Description

Turn your STP into an erect penis with a silicone insert rod. To use, simply slide the silicone Erection Rod inside the funnel of your STP and you are ready to go! The erection rods are hand poured so light imperfections or bubbles may naturally occur in the pouring process.

STP (STAND TO PEE) DEVICE | 4.5" REALISTIC

Quick Tip: We recommend applying a water based lubricant to the silicone erection rod before insertion to reduce friction.
