A hollow strap-on is a wearable dildo you slide into, so you can penetrate your partner with or without an erection. This Master Series Infiltrator set ships with the black shaft and the harness together, so there's nothing else to buy before your first night with it.

Features

• Hollow shaft: wear it soft, half hard, or fully hard. The open interior also adds sensation for the wearer as you thrust.
• Thick, veined body: real girth and raised veins along the shaft. This is a size-play toy, not a starter piece.
• Rigid sides: the walls hold their shape under pressure instead of folding, which is what separates a good hollow dong from a floppy one.
• Adjustable unisex harness: straps at the waist and between the legs, so it fits a range of body types and stays put.
• Metal O-ring on hook-and-loop straps: pull the ring free and swap in a different dildo whenever you want. The harness works on its own.
• Color: black. Includes dildo and harness.

Materials and care

TPE shaft, ABS plastic and metal hardware, PU leather harness. TPE is porous, so wash it with warm water and mild soap before and after every use, let it dry completely, and store it in its own bag away from other toys. Use a water-based lube only, and use plenty of it. Silicone lube will degrade the shaft. A condom over it makes cleanup faster and is smart if you're sharing. Spot clean the PU leather harness with a damp cloth. Don't soak it, don't machine wash it.

Honest notes before you buy

The girth is the whole point of this toy, and that means it's too much for most people who haven't worked up to it. Warm up with something smaller first. TPE can have a faint plastic smell out of the box that fades after a wash. Because the shaft is hollow and heavy, it can shift or nod at the base during hard thrusting, so cinch the straps tighter than feels necessary and re-check them partway through. And TPE isn't sterilizable the way silicone is, so this one is best kept to one partner or used with condoms. If you want a body-safe shaft you can boil, look at our silicone dildos paired with a separate harness.

FAQ

Do I need an erection to use a hollow strap-on?

No. That's the reason hollow strap-ons exist. You slip inside the shaft and the harness holds it in place, so it works soft, semi-hard, or hard. Partners with no penis can wear it too by using the harness and O-ring alone.

Can I use my own dildo with this harness?

Yes. The metal O-ring is held by hook-and-loop straps, so you can release it and fit another flared-base dildo that matches the ring size. Measure the base of your toy first so it seats snugly without slipping through.

What lube should I use with it?

Water-based, and more than you think you need. TPE reacts badly to silicone lube, and a shaft this wide needs steady reapplication. Keep the bottle within reach and go slow at the start.
