Full Anatomy Sheath Underwear with Balls & Silicone Briefs — Platinum Silicone Wearable Cock Sleeve Pant for Men Couples & ED

Complete. Convincing. Yours. — The Full-Anatomy Strap-On Dildo That Goes All the Way

Most strap-ons stop at the shaft. This one doesn’t.

The Full Anatomy huge realistic sheath underwear is sculpted as a complete male form — shaft, glans, and a fully formed scrotum with two testicles — all cast in one seamless piece of platinum liquid silicone. Worn via an integrated brown silicone briefs system, it sits flush against the body and moves with it. The result is the most anatomically complete strap-on experience available.

Designed for lesbian couples, people managing erectile dysfunction, and anyone seeking genuine penis extension with full visual realism.

✦ What Makes Domlust Silicone Sheath Underwear Different

The addition of sculpted testicles changes everything about how this product looks, feels, and functions during use:

• Visual completeness — the full male anatomy creates a convincing appearance from every angle
• Tactile realism — the scrotum adds natural weight and movement at the base
• Psychological immersion — for both the wearer and their partner, the experience reads as genuinely anatomical
• Perineal stimulation — the scrotum base can provide gentle pressure against the wearer’s body during use

✦ The Silicone: Platinum-Grade, Skin-Tone Finish

Every component is cast from platinum liquid silicone — body-safe, non-porous, latex-free, and phthalate-free. The skin tone is a warm natural beige, pigmented throughout the silicone (not surface-painted), so it won’t fade, peel, or discolour with regular use and cleaning.

The surface texture captures fine anatomical detail across the entire form:

✦ The Box Briefs: Brown Silicone, Three-Opening Design

The integrated brown silicone briefs feature a three-opening construction — two leg openings and one central wear opening — that distributes the product securely across the hips and thighs. The silicone is ultra-elastic and conforms to the body without bunching, slipping, or requiring adjustment.

No buckles. No straps. No harness to assemble. Pull on, position, and go.

✦ Who This One-piece Cock Sleeve Pant Is For

• 💚 Lesbian & queer couples — the most anatomically complete strap-on experience for penetrative sex
• 💙 Erectile dysfunction — a discreet, fully functional solution that performs independently of natural erection
• 🖤 Penis extension & girth enhancement — adds length, circumference, and the visual weight of a complete anatomy
• 💜 Roleplay & fantasy — the testicle detail creates full immersion for both partners
• ❤️ Trans men & non-binary individuals — a body-affirming option with complete anatomical representation

✦ Care & Maintenance

Rinse thoroughly with warm water and mild soap after every use. The non-porous silicone surface does not harbour bacteria and cleans easily. Do not use silicone-based lubricants — water-based lubricants only. Do not boil or autoclave. Store flat in a cool, dry place away from direct sunlight. Clean before first use.

Questions & Answers

Q: Do the testicles serve a functional purpose, or are they purely aesthetic?

A: Both. Aesthetically, they complete the anatomical picture and make the product significantly more convincing visually. Functionally, the scrotum adds natural weight at the base that moves during use, and can provide gentle perineal pressure against the wearer’s body — a sensation many users find adds to the experience.

Q: How does the three-opening briefs design differ from a standard two-opening design?

A: The three-opening design — two leg openings plus a central wear opening — distributes the product more evenly across the hips and thighs, reducing the tendency to shift or rotate during movement. It also allows the scrotum to sit naturally at the front without the briefs pulling it out of position.

Q: Is this suitable for someone with erectile dysfunction who wants their partner to be unaware?

A: The full anatomy design — including the testicles — makes this the most convincing option for that use case. The skin-tone silicone, realistic texture, and natural weight all contribute to an experience that reads as genuinely anatomical. Many users with ED report that this product restores both confidence and spontaneity.

Q: Can the shaft be used for anal play as well as vaginal?

A: Yes. The platinum silicone is body-safe and non-porous, making it suitable for both vaginal and anal use. Use plenty of water-based lubricant and clean thoroughly after use. The non-porous surface makes hygiene straightforward.

Q: How do I find the right size in the briefs?

A: Please refer to the product dimensions for waist and hip size guidance. The ultra-elastic silicone accommodates a broad range of body sizes, but checking measurements before purchase ensures the best fit and most secure wear.

Q: Does the skin tone match fair skin accurately?

A: The beige skin tone is designed to match a natural fair-to-medium complexion. The pigment is mixed throughout the silicone during casting, so the colour is consistent and won’t fade. Under clothing, the tone reads as natural skin against most body types.
