Abstract

A curvilinear reciprocating device for sexual stimulation is disclosed. The curvilinear reciprocating device has a main body; a curved stimulation member, which is configured to stimulate an erogenous zone of a human body, including a proximal end portion and a distal end portion and wherein the proximal end portion is coupled to the main body; an actuator at least partially disposed within the main body and configured to actuate the distal end portion to move from a first position away from the main body to a second position that is closer to the main body than the first position; and a rebound mechanism configured to rebound the distal end portion from the second position to the first position, thereby causing the distal end portion to reciprocate in a curvy trajectory between the first position and the second position.
