Aspects of the disclosure provide a massage device accessory that can be used to generate a reciprocating motion for a massage device that is coupled with the massage device accessory. The massage device accessory may be a single-piece of substantially rigid material that has a L-shaped bend and provides for elastic deformation between a relaxed first position and a deformed second position. The accessory further includes a securement surface or sleeve for a massage device, and an aperture for a strap, where a force applied to the strap will deform the accessory to move one end from the first position toward the user at the second position, and release of the force will allow the accessory to revert to its original shape, such that repeated application and release of force on the strap results in a reciprocating motion of the massage device.
