Master Series Boner Briefs Silicone Penis Strap On in Large
Overview
The Boner Briefs are silicone panty-shorts that let you live out a fantasy, explore a kink, or simply enjoy gender-affirming packing panties. The stretchy, phthalate-free silicone has a large, poseable dildo with balls at the front, so you can angle it to the right spot for a partner. The realistic look and feel make the fantasy easy to step into.
The back of the panties has an anal opening, so the wearer can enjoy stimulation without removing them. Be sure to measure your hips and waist to get a perfect large size and fit. Wear them under pants for a fully masculine look or under a dress for a hidden surprise. They sit with the rest of our fetish gear and apparel.
Key features
- Poseable shaft: The large dildo with balls bends and holds its angle so you can aim it for a partner.
- Rear anal opening: An opening at the back lets the wearer enjoy stimulation without taking the panties off.
- Realistic silicone: Phthalate-free silicone gives a lifelike look and feel in a flesh tone.
- Gender-affirming wear: The packing design suits affirming everyday wear as well as partner play.
- Stretchy fit: The stretchy silicone pulls on by rolling it over the skin for a snug fit.
Pull-on packing panties
Getting the fit right matters. Apply talc-free baby powder or 100 percent cornstarch to skin and panties before wearing, then roll the panties up or down over the skin rather than pulling, which can tear the silicone.
When you are ready for play, use water-based lube. For cleanup, rinse with warm water and mild soap, spray with toy cleaner and let air dry away from heat and direct sunlight, stored apart from other silicone toys.

Materials and construction
The Boner Briefs are made entirely from stretchy, phthalate-free silicone in a flesh tone, molded into panty-shorts with a poseable shaft and balls at the front and an anal opening at the rear. The realistic detailing extends to the look and feel of the silicone. Use only water-based lube, and keep the panties away from heat and other silicone toys.

Frequently asked questions about the Boner Briefs
How do I know if I need the large size?
Measure your hips and waist before ordering, then choose large if your measurements fall at the upper end of the range. A correct fit keeps the Boner Briefs snug and comfortable, since the stretchy silicone is designed to hug the body once rolled into place.
How do you put on the Boner Briefs?
Apply talc-free baby powder or 100 percent cornstarch to your skin and the panties first. Then roll the large Boner Briefs up or down over your skin rather than pulling them, which protects the stretchy silicone from tearing as you ease them into position.
Can the wearer be penetrated while wearing them?
Yes, the back of the Boner Briefs has an anal opening, so the wearer can enjoy stimulation without removing the panties. The poseable shaft at the front handles partner play while the rear opening keeps the wearer accessible at the same time.
Is the dildo poseable?
Yes, the large dildo with balls at the front is poseable, so you can angle it to the right spot for a partner. The realistic, phthalate-free silicone holds its shape, letting you aim the shaft for comfortable, well-positioned partner play.
What lube works with the silicone panties?
Use water-based lube only with the Boner Briefs. Silicone-based lube can degrade the phthalate-free silicone over time, so a water-based formula keeps the material in good condition. A condom over the shaft can also help protect it from bodily fluids.
How do I clean and store them?
Rinse the Boner Briefs with warm water and mild soap, spray with a toy cleaner, then let them air dry. Keep them away from heat and direct sunlight, and store them separately from other silicone toys to prevent the materials from reacting.
