The story

A heavyweight dual-orifice stroker from Oxballs's MasterJack line — built for users who want serious heft and two distinctly textured holes. The blubbery Plus+SILICONE construction with industrial diamond-plate grip patterns delivers a unique handheld feel.

One end has a tighter butt-pucker hole with inner ribs and nubs, while the other end carries a different texture profile for varied scene play. The built-in handle keeps grip secure even after extensive lubrication during longer sessions.

Wash with warm water and mild soap. Water-based lubricant only when paired with silicone toys. Store separately from other silicone.

Good for: heavyweight strokers, dual-orifice variety, secure grip handles, intermediate-to-advanced users, body-safe materials.

Body-safe materials. Brands we trust.

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.
