Roommates Alison and Star discover that they share a special affinity for water. It was bound to happen sooner or later, sharing a bathroom and similar work schedules.

Alison makes the discovery first, heading to the bathroom to brush her teeth, she finds it occupied. Peaking through the door she discovers a surprising but familiar sight... Star masturbating in the bathtub, still wearing her nightgown. The wet fabric molded around her body as she splashes and moans submerged in the warm water. Instead of turning away, Alison allows her hands to slide under her pajama bottoms. Watching her roommate enjoying herself in the water, Alison quickly begins to masturbate, feeling compelled to catch up to her wet roommate's level of arousal. She continues to look through the door, watching Star as she bucks in the water, sliding her wet hands in and out of her wet pussy. Alison matches Star's tempo and clamps her hand down over her mouth as Star submerges completely in the water, muffling the sounds of her orgasm.

Later that day, Star comes home from work and hears the shower running. She peaks through the bathroom door and discovers Alison, still half dressed in her work clothes, pleasuring her dripping wet body under the warm shower spray. Alison makes to attempt to stifle her moans as Star looks on, partially undressing and getting herself off to the sight of her sexy, soaking wet, roommate.

Freshly showered, Alison walks out into the back yard. It's the last days of summer and she contemplates the garden hose. Bending to turn it on, Alison is shocked to find Star sitting in a chair with the hose in her hand. Wordlessly, Star pats her lap and beckons Alison to her. The two roommates kiss and grind on each other's laps as the cool stream of water soaks them from head to toe. Alison pulls away and asks if they can take the hose with them into the pool.

Submerged in the deep warm water, Alison and Star explore each other's bodies. Still partially clothed they employ the hose as a portable jet, spraying the hard steady stream on each other's pussies, licking, tasting, enjoying every inch of each other's bodies in a deep underwater lesbian sex session.
