As he dove into the cold water, white butt high in the air, barely making a splash in a near perfect dive, I watched with pleasure from my vantage point in the hull of the 35-foot yacht. After a short swim he returned to the boat, tanned skin glistening with water droplets. She met him there, as she pressed her sun warmed body up against his cold wetness. His hands came around to cup her ass, pushing into her warmth. She squealed with shocking delight at the cold of every part of him. She pulled away, just a little, before kneeling and taking his cold member fully into her mouth. Gentle friction warming the soft uncircumcised package, interspersed with that wicked tongue, teasing it to its hardness while her warm hands cupped his perfect cleanly shaved sack. His moans of delight reverberated through every fiber of my being as I felt my own juices flowing. Just when I thought I could no longer stand to be the observer, she turned away from his erect cock, my breath caught. She leaned onto the bench seat, ass in the air, hot cunt dripping, beckoning him in. Rubbing his cock up against her waiting cunt, rubbing her ass before bending down and lifting her to mouth level, he licked and teased until neither one of them could hold out any longer. As he lowered her over his throbbing member, gently before plunging deeply inside her. They fucked until she came with trembling screams of delight before he blew his load in moanful pleasure.
