Kasie, the thickly muscled biker lady, arrives at the beach on her Harley. She strips off her leather and into her muscle-exposing, micro bikini for a jog along the California surf.

Kasie soon discovers another lovely female bodybuilder, Desire, and observes that she is experiencing torrid, private emotions while reclined on her beach blanket.

A strong vision of Muscle Mass Magnetism transpires. Soon these two physique-endowed beauties drift into the water together to kiss and nibble upon each other's muscles.

Next, Desire entices Kasie to take her back to Kasie's home. They mount Kasie's Harley for a tantalizing ride to Kasie's place.

Audible, amorous poolside sounds are detected by yet another prodigious female physique, Michelle Ivers, the delivery lady! She arrives to find Kasie and Desire consumed in sizzling passion. Kasie beckons muscular Michelle to join them in what becomes the ultimate trilogy of muscle amour.
