DoubleJoy – Stretch & Double Penetration
DoubleJoy is a C-shaped silicone plug worn during sex – it stays inside while your partner penetrates alongside it. You feel fuller, your partner feels you gripping them more. Also great for DP sensation with a toy, or to increase diameter during stretching training.
Because of its C-shape, DoubleJoy folds for insertion – you can go up to 1 cm larger than your usual max. The open side is always roughly half the max diameter. Choose your size by the neck diameter.
We recommend Soft (Shore 00-50) or Extra Soft (Shore 00-30) for most users. Available from 6 to 15 cm.

💑 What DoubleJoy is actually for
DoubleJoy solves a problem many couples know well – the feeling that something is missing during sex. Whether it's because one partner has a slimmer penis, or because stretching has changed what feels satisfying, DoubleJoy bridges that gap. It's a C-shaped silicone plug that stays inside while a penis or toy enters alongside it. Both partners feel more – more pressure, more friction, more connection.
🔀 Three ways to use it
1. More fullness during sex with a partner
Insert DoubleJoy before penetration. It holds your opening stretched and fills the space around your partner's penis – so you feel fuller, and your partner feels you gripping them more tightly. You still feel their natural shape, warmth and movement. Nothing is blocked, nothing is hidden behind silicone.
2. Double penetration sensation
Insert DoubleJoy and add a dildo, vibrator or your partner's penis into the open side. The result is a realistic DP experience – two points of pressure, two sensations at once. An effective way to explore DP, whether solo or together. For more on preparing for DP safely, see our article on Advanced Practices.
3. Stretching with more diameter
Already comfortable with your current plug size? Insert DoubleJoy alongside your usual toy to increase the total diameter. A controlled, gradual way to push your training further without jumping straight to a larger plug. This technique is explained in detail in our guide to Stretching Styles and Techniques.
📐 How to choose your size
Always choose by the neck diameter – that's what stays inside and determines how stretched you are while wearing it. Because the C-shape allows DoubleJoy to fold slightly during insertion, you can comfortably go up to 1 cm larger than your usual max. If your current comfortable max is 8 cm, start with an 8–9 cm DoubleJoy.
The open side – the space for a penis or toy – is always approximately half the max diameter. A 10 cm DoubleJoy leaves roughly 5 cm of open space alongside it. Keep that in mind when choosing for partner play.

✨ Smooth surface – a real difference
Every DoubleJoy is handmade from 100% platinum-cured silicone with a perfectly smooth, glass-like finish. At the rim, where DoubleJoy sits alongside a penis or toy, that smoothness reduces friction and makes everything more comfortable for both partners. It's one of the details our customers mention most often.
🧼 Material and care
100% platinum-cured silicone – body-safe, non-porous and built to last for years. Clean with mild soap, a chlorine-free toy cleaner, or boil to fully sterilize. For full hygiene and lubrication tips, see our guide on Safety, Hygiene and Lubrication.
🎨 Customization
Each DoubleJoy is handmade to order in your chosen color and firmness – single color, split or two-color transition. Need a size outside the standard range? Contact us directly – custom sizes are always possible.

❓ Frequently asked questions
How do I know which size to choose?
Choose by the neck diameter – that's what stays inside. As a starting point, pick a size 1 cm larger than your current comfortable max diameter. The C-shape lets DoubleJoy fold slightly during insertion, so you can take a bit more than usual. If you're unsure, write to us and we'll help you choose.
Can DoubleJoy be used anally?
Yes – DoubleJoy works both vaginally and anally. For anal use, we recommend Extra Soft firmness and careful warm-up. The same size selection logic applies – choose by neck diameter and go generously with lubricant.
My partner and I have a size mismatch – will DoubleJoy help?
That's exactly what many couples use it for. DoubleJoy fills the space around your partner's penis, so you feel fuller and they feel you more. You can still feel their natural shape and movement – nothing is blocked. Most couples start with a size where the neck diameter roughly matches their current comfortable stretch level.
