Sex toy

A sex toy comprising:

• a body housing a motor;
• a shaft coupled to the motor, the shaft comprising a helical groove;
• a massaging member mounted over the shaft, the massaging member mounted to a traveler, the traveler comprising a head that extends over a distal end of the shaft, the traveler in engagement with the shaft via a shoe;
• the head enveloping a torque sleeve covering the shaft and one or more fins integrally formed on the outside of the torque sleeve, so that when the torque sleeve is in position covering the shaft the one or more fins extend along at least a part of a length of the shaft to provide additional structural support and rigidity to reduce or eliminate any unintended movement of the toy;
• the torque sleeve comprising a guide provided between the shaft and the traveler, the guide comprising a slot within the head, the slot extending along the shaft to maintain an angular position of the shoe relative to the shaft while permitting linear movement of the shoe along the shaft;
• and
• a controller coupled to control the motor to drive the massaging member in a reciprocating motion along the length of the shaft;
• wherein the traveler is in engagement with the shaft and each of the one or more fins engaging with a complementary cavity on the traveler, and the shoe comprises a shoe head that is slidably mounted in the helical groove so that when the motor rotates the shaft the traveler is driven along the shaft and the one or more fins to drive the massaging member in a reciprocating motion along the length of the shaft that results in a change of length of the sex toy.
