Medium Silicone Penis Strap-On Briefs

The Medium Silicone Penis Strap-On Briefs offer a lifelike way to step into fantasy roleplay, explore your kinks, or enjoy gender-affirming underwear. Designed as silicone panty-shorts with a realistic, poseable dong at the front, these briefs combine the look of a strap-on with the feel of snug, stretchy silicone underwear.

Produced by XR LLC under the Master Series brand, this medium-sized style is crafted to provide both visual realism and functional versatility. Whether you are experimenting with gender expression, planning a night of roleplay, or simply curious about a new kind of strap-on experience, these briefs are built to support your exploration.

Stretchy silicone panty-shorts

The body of the briefs is made from stretchy, phthalate-free silicone that hugs your curves. This panty-short design is intended to sit close to the skin, creating a snug and secure feel while you move. Because the material stretches, it can accommodate a range of waist and hip measurements when properly sized.

For the best fit, the briefs are designed to fit a waist circumference of 20 to 30 inches (50.8 cm to 76.2 cm) and a hip circumference of 31 to 42 inches (78.74 cm to 106.68 cm). Measuring your body before purchasing helps you choose the right size and enjoy a more comfortable, supportive fit.

Realistic, poseable dildo with balls

At the front of the panty-shorts is a realistic silicone dildo complete with balls at the base. The dong is poseable, allowing you to adjust the angle to better suit your partner's body and preferred positions. This adjustability can help you find a more comfortable and pleasurable alignment during penetration.

The dildo offers an insertable length of 6.7 inches (17.018 cm) and a widest insertable diameter of 1.6 inches (4.064 cm). These measurements provide a medium-sized option that many users find satisfying without being extreme. The light color and realistic shape are designed to enhance the visual experience for both wearer and partner.

Anal opening for backdoor play

The back of the briefs includes an anal opening, so you can enjoy backdoor stimulation without removing the panty-shorts. This feature allows you and your partner to explore multiple types of play in a single session, switching between front and backdoor pleasure while the briefs stay in place.

Ideal for roleplay and gender affirmation

These silicone briefs are well suited to fantasy roleplay, kink exploration, and gender-affirming wear. You can pull on the briefs and slide a pair of pants over them to lean into a more masculine presentation, or pair them with a dress or skirt to blend masculine and feminine elements for a hidden surprise underneath your outfit.
