Devil Dildo 20.3 x 4.4 cm - Thermoreactive

Devil — The dildo that adapts to your temperature… and your desires

The Devil by SilexD is no ordinary dildo. With its fantasy design in a striking red-to-black gradient, its ribbed shaft and sculpted head, it sets the tone from the start: this is a toy for guys who want something beyond the basics. But the real game changer is the material. The thermoreactive Silexpan changes consistency with temperature. Want it firm and rigid? Stick it in the fridge. Want it soft and lifelike? Heat it up. You decide what you're going to take.

Silexpan — The material that changes the rules

Silexpan is a patented material by SilexD that combines the benefits of medical-grade silicone with shape-memory technology. The Devil is built with dual density: a firm inner Silexpan core wrapped in an ultra-soft liquid silicone skin. The feel is stunningly realistic — soft on the surface, solid on the inside, just like a real hard cock.

And that's where the thermoreactivity kicks in:

For a softer dildo: Submerge it in boiling water (max. 2 minutes) or microwave it (max. 30 seconds). The heat softens the Silexpan and brings it close to body temperature. The sensation is smoother, more realistic, more organic.
For a harder dildo: Place it in the refrigerator (no time limit). The cold solidifies the Silexpan and makes the shaft much more rigid and firm. Perfect for those who want to feel a real, solid stretch.

A fantasy design that stands out

The Devil doesn't try to look like a realistic cock. Its look is bold: a spectacular red-to-black gradient, a stylised head, and most importantly a ribbed shaft with pronounced ridges that massage and stimulate the walls with every stroke. These textured rings create extra friction on insertion and withdrawal — every thrust works the nerve endings in ways a smooth dildo simply can't. That's exactly what makes fantasy dildos special: shapes designed for pleasure, not anatomy.

The twisted-testicle base completes the demonic look and features a powerful suction cup that holds firm on any smooth surface.

How to use it

Set up your temperature session: Decide whether you want a soft Devil (heat) or a firm Devil (cold) and prep it accordingly. For your first time, the heated version is recommended — softer, more comfortable, ideal for getting used to the ribbed texture.

Lube up generously: Use water-based lubricant only. Silicone-based lube damages the surface — no compromises on this. A thick anal lube gel is ideal for fully enjoying the textures.

Suction cup mode: Stick the Devil on the floor, a chair, a shower wall — any smooth surface works. Sit on it and control the depth and speed yourself. Hands-free, you can stroke your chest, tease your nipples, or jerk off at the same time.

Handheld: Hold the Devil by the base and play with the angles. The shaft rings stimulate differently depending on speed and tilt. Alternate between slow, deep thrusts to feel every ridge, and fast strokes for intense friction.

Play ideas

Hot / cold session: Prepare two versions of the Devil if you have two, or alternate in the same session. Start with a chilled Devil — the firmness creates a powerful penetration sensation. Then warm it up and go again — the softness brings a completely different comfort. The thermal contrast on your inner walls is a kink worth exploring.

Suction cup ride: Stick the Devil on your shower floor and let the hot water run over you while you ride it. The combo of hot water + ribbed texture + controlled depth is a recipe that works every single time.

With a partner: Let your partner fuck you with the Devil while he jerks you off or blows you. The shaft ridges create sensations his cock simply can't replicate — it's complementary, not a replacement. You can also use it for double penetration if you enjoy the feeling of being filled. The Devil from the fridge + your man nice and warm = an unforgettable temperature combo.

With a harness: The Devil's base is harness-compatible. Your partner can strap it on and fuck you with a toy that has textures like nothing else. Perfect for couples who want to switch up sensations without switching positions.

Care

Cleaning: Wash the Devil with warm water and a mild antibacterial soap or sex toy cleaner. The silicone is non-porous and 100% waterproof, so you can rinse it worry-free.

Lubricant: Water-based only. No silicone, no oil — it damages the liquid silicone skin.

Storage: Keep it in a fabric pouch or separate from other silicone toys to avoid surface reactions between materials.
