Master Series Hard-On Briefs Silicone Penis Panties in Large
Overview
The Hard-On Briefs are silicone packing panties that let you enjoy a fantasy, a kink, or simply gender-affirming wear. The stretchy, phthalate-free silicone carries 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 stepping into the role easy and convincing.
An anal opening at the back lets the wearer enjoy stimulation without removing the panties. Measure your hips and waist for a proper large fit. Wear them under pants for a masculine look or under a dress for a hidden surprise. They join the rest of our fetish gear and apparel.
Key features
- Poseable shaft: The large dildo with balls at the front bends and holds its angle for partner play.
- Rear anal opening: An opening at the back keeps the wearer accessible without removing the panties.
- Realistic silicone: Phthalate-free silicone gives a lifelike look and feel in a tan tone.
- Gender-affirming wear: The packing design works for affirming everyday wear and for play.
- Discreet under clothes: Pack under pants for a masculine look or under a skirt for a surprise.
Confident packing
Use water-based lube when you are ready to play, and if you want to keep the shaft clear of bodily fluids, wear a condom over it. The realistic silicone lets you play into the fantasy with a convincing look and feel.
Measure your hips and waist to land the large size correctly. The stretchy silicone rolls on over the skin, and the rear opening means the wearer can open up to a partner without taking the panties off.

Materials and construction
The Hard-On Briefs are made from stretchy, phthalate-free silicone in a tan tone, formed into panty-shorts with a poseable dildo and balls at the front and an anal opening at the rear. Use water-based lube only, clean with warm water and mild soap, and store away from heat and other silicone toys to keep the material in good condition.

Frequently asked questions about the Hard-On Briefs
What is the difference between packing and partner play with these?
The Hard-On Briefs work for both. For packing, they give a realistic masculine shape under clothing; for partner play, the poseable front shaft can be aimed and used with water-based lube, while the rear anal opening keeps the wearer accessible at the same time.
How do I choose the large size?
Measure your hips and waist and choose large if your measurements fall at the upper end of the range. The stretchy phthalate-free silicone of the Hard-On Briefs hugs the body once rolled on, so an accurate measurement gives the most comfortable and secure fit.
Can I wear them discreetly?
Yes, wear the large Hard-On Briefs under pants for a fully masculine look or under a dress or skirt for a hidden surprise. They pack discreetly, letting you blend masculine and feminine styling or conceal the packing until you decide to reveal it.
Should I use a condom over the shaft?
You can. If you want to protect the rod from bodily fluids, wear a condom over it during play. Combined with water-based lube, this keeps the Hard-On Briefs hygienic and protects the phthalate-free silicone from anything that could degrade it.
What color and material are they?
The Hard-On Briefs are tan and made from stretchy, phthalate-free silicone. The realistic molding and finish give the packing panties a lifelike look and feel, while the body-safe silicone stays comfortable for both affirming wear and partner play.
How do I care for the Hard-On Briefs?
Rinse them with warm water and mild soap, then air dry. Use water-based lube only, keep them away from heat and direct sunlight, and store them separately from other silicone toys so the materials do not react and the panties stay in good shape.
