The friend's hands roam, slippery with soap, as she massages every tense muscle, her touch becoming more intimate. His breath hitches as she reaches his throbbing erection, her fingers wrapping around it, stroking slowly. She leans in, her tongue flicking out to taste the pre-cum beading at the tip. She takes him into her mouth, her soapy breasts rubbing against his thighs, her moans vibrating around his cock. He grabs her hair, fucking her mouth with abandon, the water pouring over them. She stands, straddling him, and slides down onto his cock, her soapy pussy clenching around him as she rides him hard, her tits bouncing, until they both come undone in the steaming shower.
