Lock-In Dual-Ended Vibrating Strap-On Set by Together is a penetrative harness system with dual insertable shafts designed for couples. At 135mm and 85mm insertable lengths with 10 vibration modes, it delivers internal sensation to one partner while the contoured base stimulates the wearer's clitoris. Body-safe silicone construction with elastic waistband accommodation up to 64 inches suits couples seeking synchronized pleasure during partnered intercourse.
The dual-ended design allows simultaneous internal penetration and external clitoral contact, with both shafts vibrating through 10distinct modes. The curved bulbous heads angle to target the G-spot on the receiving partner while the harness-mounted base presses against the wearer's clitoris with every movement. Vibration travels through both insertable lengths independently, creating layered sensation that responds to depth and angle adjustment during play.
Together constructed this strap-on from ultra-smooth, body-safe silicone that conducts vibration efficiently while remaining gentle against sensitive tissue. The polyester and iron harness provides structural support with an elastic waistband stretching to 64 inches maximum, accommodating different body sizes without custom fitting. Those interested in expanding clitoral play options can explore our clit clamps range for additional sensation possibilities.
| Insertable Lengths | 135mm (primary), 85mm (secondary) |
| Material | Body-safe silicone shafts, polyester and iron harness |
| Vibration Modes | 10 adjustable settings |
| Waistband Size | Stretchy elastic up to 64 inches maximum |
| Waterproof Rating | Fully waterproof and submersible |

Combining this strap-on with manual clit stimulators allows the receiving partner additional external sensation while experiencing internal vibration. Face-to-face positioning maximizes eye contact and intimacy while enabling both partners to control depth and speed intuitively. Many couples discover that alternating vibration modes throughout a session builds sensation gradually rather than maintaining constant intensity.
After use, rinse both silicone shafts and the harness exterior with warm water and gentle soap, then pat dry completely. Avoid submerging the harness components beyond brief rinsing, as prolonged water exposure degrades the iron and polyester materials. Store in a cool, dry location away from direct sunlight, preferably in the included storage pouch to prevent dust accumulation and material degradation over time.
Body-safe silicone forms the insertable shafts, ensuring compatibility with water-based lubricants and safe contact with internal tissue. The non-porous construction prevents bacterial colonization and enables thorough cleaning between uses. The polyester and iron harness provides durable support without latex or harmful chemical coatings, making it suitable for extended play sessions.
This strap-on suits couples seeking simultaneous internal and external stimulation during partnered intercourse. It appeals to those wanting hands-free clitoral contact while penetrating a partner, eliminating the need for manual stimulation coordination. Couples comfortable with penetrative play who prioritize face-to-face contact and synchronized pleasure will find the dual-ended design particularly effective for shared arousal.
For couples who find standard penetration leaves one partner without direct clitoral contact, the dual-ended design simultaneously addresses both people's sensation needs without requiring manual intervention. The wearer experiences vibration against their clitoris with each thrust rather than providing pleasure only to the receiving partner, fundamentally shifting how couples approach shared intimate moments. Many couples discover that synchronized stimulation creates emotional and physical connection that separate toys cannot replicate—knowing both people are receiving pleasure from the same act deepens presence and responsiveness during play. For those accustomed to penetration feeling one-sided, experiencing mutual sensation through integrated design changes relationship dynamics in measurable ways.
Our independent testers evaluated harness stability during vigorous movement, vibration consistency across both shafts, and the effectiveness of the contoured base for clitoral contact. The waistband remained secure even during sustained activity, and the curved shafts delivered reliable G-spot contact angle without shifting position during use.
Testers noted that the 10 vibration modes provided sufficient variation for couples seeking different sensations across extended sessions. The magnetic charging connection functioned reliably throughout testing without requiring alignment fussing. Individual results may vary based on anatomy, sensitivity, and usage patterns.
| Product | Unique Advantage | Key Difference | Choose This If You Want |
|---|---|---|---|
| Lock-In Dual-Ended Vibrating Strap-On Set by Together | Dual shafts with simultaneous internal and external vibration plus integrated clitoral base stimulation | Only design combining penetration with automatic wearer clitoral contact through harness design | Mutual pleasure where wearer receives direct stimulation during partnered penetration |
| Clit Pumps | Suction-based sensation for isolated clitoral amplification and swelling | Manual or battery-powered suction rather than vibration; external-only contact | Heightened sensitivity through vacuum effect before partnered play |
| Suction Gripper Dildos | Hands-free positioning through suction cup mounting to hard surfaces | Non-vibrating penetration; requires surface availability; no harness structure | Hands-free solo play or solo-to-partnered transitions without harness fitting |
| Clit Enlargers | Topical application for temporary clitoral enlargement and sensitivity heightening | Non-mechanical; chemical-based effect; requires application time before play | Enhanced sensitivity for existing toys rather than integrated mechanical stimulation |

Effective strap-on play depends on communication about pressure, depth, and vibration intensity, allowing both partners to signal comfort and arousal in real time. Many couples find that explicit discussion beforehand about boundary-setting and sensation preferences creates safer, more enjoyable experiences than assuming comfort levels. Our comprehensive guide to strap-on play covers positioning, communication frameworks, and technique approaches for partners new to harness-based penetration.
