The story

A boxer-brief-style strap-on harness shaped to wear like ordinary underwear, with discreet enhancement built in. The form-fitting cut works under clothing for users who want to extend the strap-on dynamic beyond bedroom scenes.

The soft double-stitched fabric stays comfortable across longer wear without bunching or chafing. An internal pocket houses a stimulator (not included) for wearer-focused sensation, and the double-panel interior accommodates a packer, probe, or dildo with a flared base.

Hand wash with mild detergent and air dry. Sized 2XL/3XL for users with larger frames who want functional strap-on gear in their actual size.

Good for: daily-wear strap-on use, plus-size fit, wearer-stimulation pockets, discreet packing, partner penetration.

Questions before you buy?

Will this arrive in discreet packaging?
Yes — all orders ship in plain, unmarked boxes with no product names and no brand logos on the outside. We ship discreetly on every order, automatically.
What's your return policy?
Sex toys can't be returned once opened — that's an industry-standard hygiene rule, not specific to us. For defective or damaged items: we'll replace or refund. Email us and we'll handle it.
Is this product body-safe?
We carry only products that meet our editorial standard: body-safe materials, no phthalates, no BPA, no latex in products marketed for internal use. Our board sets the bar; this product meets it.
How do I clean it?
For non-motorized toys: warm water and mild soap, or a dedicated toy cleaner. For motorized or electronic toys: wipe with a damp cloth and toy cleaner — don't submerge unless the product is rated waterproof. Waterproof rating is noted in the specs section when applicable.
Is this rechargeable?
Check the specs section on this page for charging details. Most modern vibrators and massagers include a USB-C or magnetic charger. Battery-powered products are noted clearly in the Materials & specs accordion above.
Can I order anonymously?
Yes — guest checkout is available, no account required. We ship in plain packages with no external branding. The charge on your card statement appears as "Alexander Institute" — the parent company that owns Loving Sex, nothing that identifies the product type.
