About this product

The Double Up Plug by Doc Johnson is a connector core that transforms any pair of Vac-U-Lock attachments into a shared or solo experience. Instead of buying complete fixed double-ended toys, you build exactly what excites you by pushing compatible toys onto each end until they lock securely. Both ports grip attachments with equal force, so you can mix sizes, textures and functions across the wider range of anal sex toys without limitation.

The frosted surface reduces friction on insertion while the compact length keeps partners closer during play. Unlike flexible double-ended toys that bend to suit positioning, this system stays rigid and stable. You build, use, then swap attachments instantly—no need to store multiple complete toys or compromise on the exact combination you want.

The features that matter

  • Dual Vac-U-Lock ports: Both ends grip attachments securely without slipping, even during intense use or when mixing different toy weights.
  • Frosted finish: Smooth surface glides easily during insertion while maintaining the firm connection required for stable, confident play.
  • Body-safe silicone: Phthalate-free construction keeps you safe during extended sessions or frequent use with different attachments.
  • Compact core design: Short connector length positions partners or your hand closer to the point of contact, avoiding awkward spacing.
  • Instant customisation: Swap attachments without tools or disruption, so you can change sensations mid-session or try new combinations on the fly.

How to use an anal toy safely

Start with plenty of Anal Lubricant on both the toy and your entrance—silicone needs generous slickness to slide smoothly. Warm up with smaller toys first, or use dedicated Anal Dilators if you are new to anal play. Push the Double Up Plug in slowly, pausing if you feel resistance. Never force it. Once inserted, you or your partner can push toys onto each end until they lock firmly in place.

During use, stay relaxed and listen to your body—stop immediately if you feel sharp pain (discomfort fades with relaxation; pain does not). After play, remove attachments carefully and wash the plug and all toys with warm water and toy cleaner. Store dry and separately from other toys. If you are sharing this toy with a partner, clean between uses. Never share toys without cleaning in between, and use a barrier method if you are not fluid-bonded.

Who it suits

Couples wanting to explore different sensations together find this system lets them build exactly the combination they need.

Great if you…
  • Want complete control over attachment combinations without buying multiple fixed toys
  • Are exploring anal play as a couple and want to try different textures and sizes
  • Prefer a stable, rigid connector that keeps partners positioned close together
  • Like the security of Vac-U-Lock's firm grip and instant swapping between sessions
Maybe not if you…
  • Do not own any Vac-U-Lock compatible attachments yet (you will need to buy toys separately)
  • Prefer complete double-ended toys that need no assembly or attachment swapping
  • Want flexibility to bend or angle the toy to suit different body positions
Always use generous lubricant, relax fully before insertion, and stop immediately if you feel sharp pain rather than discomfort—do not push through pain signals. Safety first. Use only toys with a flared base or retrieval cord — anything without one can be drawn inside and require medical removal. Go slowly, use plenty of lubricant, and seek medical advice for bleeding or lasting pain. This information is general in nature only and is not medical or professional advice; it does not account for your individual circumstances. Stop use and seek medical advice if you experience pain, numbness, swelling, discolouration, bleeding or persistent irritation.

Care and storage

Wash the plug with warm water and mild toy cleaner after every use. Rinse thoroughly and pat dry with a clean cloth before storing. Keep it in a separate clean pouch away from other toys and direct sunlight. Do not use silicone-based lubricant (only water-based), as it can degrade silicone over time. Store in a cool, dry place. The Vac-U-Lock ports are durable, but avoid dropping the plug on hard surfaces.

Where to read more

Understanding anal toy materials, sizing and technique takes time—most people benefit from solid background reading before their first purchase. The Anal Sex Toys Guide covers warm-up, material safety, and what to expect at each stage of exploration. It also explains how Vac-U-Lock systems compare to fixed toys and which approach suits different preferences.

What to expect

by Risetob

The Vac-U-Lock connector sits shorter than many double-ended toys, which most couples find helpful—you stay closer together rather than uncomfortably spaced apart. The frosted finish feels substantial on the hand and slides smoothly once well-lubricated. First-timers often worry the push-fit attachment mechanism will fail, but it locks firmly and stays locked even during vigorous use. The real trade-off is that you need to own compatible toys separately; the plug itself is a core only.

Most people discover their actual preferences once they start mixing attachments. Someone might think they want a particular size or texture, then find a completely different combination works better in reality. That flexibility is the whole point—you build, experiment and adjust without buying ten complete toys. The compact design holds up well over time and the Vac-U-Lock ports do not wear out from normal use.

Cleaning is straightforward because the plug has no batteries, motors or crevices where lubricant traps bacteria. Wash, rinse and dry. Attachment swapping takes seconds, so most couples find themselves trying new combinations more often than they expected. Solo users appreciate having a secure handle while the other end delivers sensation—it gives you control and stability that loose toys cannot.

How it compares

Style Best for Customisation Setup required Positioning
Double Up Plug (Vac-U-Lock) Couples or solo players wanting variety Fully customisable—swap any compatible toys Push toys onto ports until locked Rigid, compact, keeps partners close
Fixed double-ended toy Users wanting one consistent experience None—single preset combination only No setup needed Fixed, but bends on some models
Flexible double-ended toy Users needing angle and position changes Limited—one material, shape and texture No setup needed Bends to suit different body angles
Removable-head system (other brands) simple-conscious buyers Limited compatibility with own-brand toys only Screw or snap heads on and off Varies by model, sometimes loose
