Cory Chase, the sultry milf, and Talulah Mae, her stepsister with a penchant for tattoos, find themselves in a summer heatwave, both figuratively and literally. As Cory and Talulah bask in the sun, their eyes meet, sparking a taboo curiosity. Cory's husband, Luke Longly, enters the pool area, his cock already hard from the sight of his stepmom and sister. Cory, with a mischievous glint in her eye, suggests a game of 'catch.' As Luke tries to catch the ball, Cory and Talulah tease him, their bodies rubbing against his, their big tits pressing into him. The game escalates, ending with Cory and Talulah sharing Luke's cock, their tongues dancing, before Cory takes him deep, her pussy tight and eager for his throbbing member.
