Lifeguards Mary Carey and Celeste Star take their rescue training to the next level, using a glass dildo to demonstrate closed-chest cardiac massage. Mary, the busty blonde, straddles Celeste, the brunette nympho, as they practice mouth-to-mouth. Their hands glide over each other's natural, ample breasts, and the dildo, slick with lubricant, slides between their lips and thighs, simulating the rhythm of life-saving compressions. Their moans of pleasure drown out the sound of the ticking clock, as they lose themselves in the thrill of their forbidden training session.
