The Blush Lock On Strap-On Harness is a black nylon strap on harness built around Blush's Lock On attachment, which holds a compatible dildo firmly in place even during vigorous thrusting. The straps adjust to fit waists up to 60 inches, and a small pocket holds the included vibrating bullet so the wearer gets sensation too. It suits couples who want a stable, adjustable harness and are happy to pair it with Lock On dildos.
Most harnesses hold a dildo by squeezing its base inside an O-ring, which works but can wobble with a smaller base or during hard thrusting. Blush's Lock On system adds a fixed attachment point: a compatible dildo connects to the Lock On fitting on the front of the harness and stays put. That's the main reason to choose this harness. You get a firm, stable connection that doesn't shift as you move, which makes it easier for the wearer to control depth and angle, and less likely that anything slips out at the wrong moment.
The catch is compatibility. The fitting is made for dildos sold as Lock On compatible, so check that before you buy a toy to go with it. Blush calls this an O-ring harness, but the supplier doesn't say whether ordinary flared-base dildos fit securely without the Lock On fitting, so don't count on it for those.
The nylon straps adjust to fit waists up to 60 inches, so it covers a wide range of bodies. Step in, pull it up so the front plate sits over the pubic bone, then tighten the straps evenly on both sides. It should feel snug and stable without digging in. A harness that's too loose lets the dildo droop and puts more strain on the wearer's hips; too tight and it chafes. Do a few test thrusts before you start, and adjust once more after a couple of minutes, since straps often settle.
Wearing a strap-on can leave the wearer with little direct sensation. This harness has a pocket behind the front that holds the included one-speed vibrating bullet, so the wearer feels buzz against their own body while they thrust. It runs on one AAA battery, which isn't included, so pick one up before your first session. The bullet is optional. Leave the pocket empty if you'd rather not have vibration, or slip the bullet out and use it by hand during foreplay.
If you're new to strap-on sex, start with a smaller, flexible dildo and plenty of water-based lube on it. Let the receiving partner guide the first few strokes, or lie back and let them ride, which takes pressure off the wearer while you both learn the rhythm. Positions where the wearer can use their hips rather than their back, such as kneeling, are easier at first. After use, remove the bullet and dildo, hand-wash the nylon straps in warm soapy water and let them air-dry. Wipe the bullet with a damp cloth rather than soaking it.
