Description

This SPT has tighter lower section fitted with a see through liner. A polished acrylic constriction is fitted between the upper and lower section. The head of the penis is drawn through the constriction with each pulsation of the milker.

Features

Sizing: This SPT has tighter lower section fitted with a see through liner. A polished acrylic constriction is fitted between the upper and lower section.

Internal diameter (50mm): The size refers to the internal diameter of the lower section. Due to the way the milker works the sizes are not that critical - as long as the penis will fit inside the acrylic tube when erect. Diameter is calculated by dividing circumference by 3.142 (π)

Constriction: The constriction should be approximately 5mm smaller than the diameter of the erect head of the penis.

Length: The Length of the lower section is 115mm – measured from mid way in the acrylic constriction to the base of the SPT. The length chosen should be the length closest to, but longer than, that of the erect penis, measured from abdomen to tip. This enables the head of the penis to be drawn through the constriction with each pulsation of the Milker.
