A sexual stimulation device having an outer skin containing heated, raised ridges surrounding an internal mechanism including two housings, a drive motor, a disc mechanically engaged with the drive motor, a shaft having a planar surface with substantially perpendicular protrusions attached at one end, and angled surfaces attached to the inner surface of at least one of the housings. As the motor and disc rotate, the shaft is translated laterally, pushing the attached planar surface and disc towards the angled surfaces, causing at least one of the housings to expand, thereby increasing the surface area of the surrounding outer skin. |
