Strap-On Harness with Dildo — Perfectly Pegged by Sei Mio

Strap-On Harness with Dildo User Guide & Play Styles

First-time pegging: why this beginner strap-on harness makes the start easy

For couples exploring pegging for the first time, the adjustable strap-on harness removes the two biggest barriers — fit anxiety and material safety. The one-size fully adjustable design cinches to any body type in under a minute, and the slimline body-safe silicone dildo keeps the introduction comfortable rather than overwhelming. Thread the dildo through the O-ring that holds the base snugly, apply water-based lubricant generously, and communicate throughout. The harness-compatible O-ring system means you can upgrade to a different size later without buying a new harness. For a deeper look at dildo options, explore our guide to dildo benefits.

Leveling up together: using the vibrating pocket and O-ring system during partnered play

Once the fit feels natural, the hidden front pocket opens up a new layer of play — drop in a bullet vibrator and the wearer gets vibrating stimulation hands-free during the session. The three included silicone O-rings let couples swap in larger or differently shaped dildos as confidence grows, keeping the pegging strap-on set relevant well past the beginner stage. This black silicone harness cleans easily between uses, so back-to-back nights are low-effort. Browse the full range at our Couples Pleasure landing for compatible accessories to layer in.
