A sexual stimulation device which provides simultaneous stimulation to male and female partners during intercourse includes a hollow elastomeric shaft portion dimensioned to receive a penis and for vaginal insertion. The shaft includes a longitudinal rib forming an interior channel, the rib functioning to stiffen the shaft and the channel providing sufficient resilience to allow insertion and removal of a penis. The shaft terminates at a closed end in a hemispherical tip and at an opposite open end in a pair of spaced annular retaining rings. A plurality of raised rings spaced axially along the shaft enhance the pleasure of the female partner. The retaining rings provide a resilient retaining force to maintain the device in position during intercourse. An electric motor with an eccentric weighted flywheel mounted in a chamber extending between the annular rings provides vibratory stimulation. An electrical wire for powering the vibratory motor extends through a conduit connecting the chamber to an attached housing enclosing rechargeable batteries. The housing also includes a second motor operably connected for rotating caged massage balls positioned to provide simultaneous stimulation to a female partner during intercourse. An elastomeric shell encloses and substantially seals the housing, while still allowing user actuation of two HIGH-LO-OFF switches providing independent control of the two motors and connection of an AC adapter for recharging the batteries. In an alternative embodiment, the hollow shaft may be omitted.
