A variable speed motor powering a crankshaft driven sealed transducer producing pneumatically induced reciprocating motion of a receiver when a male organ is inserted. The present invention employs a hermetic system to prevent loss of synchronization. The receiver is designed with an inner liner compliant enough to accommodate a plurality of sizes and shapes of male penises. The present invention produces a stroke of approximately 3 inches at a frequency of up to 350 per minute.
(b) a sealed transducer having fluid therein and a fitting thereon for fluid communication;
(c) a connecting rod;
(d) a fluid communication conduit;
(e) a generally hollow cylindrical receiver including:
(1) a pliable elongated annular bladder positioned therein;
(2) the annular bladder having a fitting thereon for connection to said fluid communication conduit;
(3) a removable cap;
(f) said means for providing reciprocating motion being connected to said sealed transducer with said connecting rod; said sealed transducer provides repeated fluid pulses to the receiver via said fluid communication conduit; said repeated fluid pulses acting on the receiver with said removable cap installed cause masturbatory motion when said receiver is placed over a male penis.
