In this adult aunt-and-nephew role-play, he gets hard after seeing his aunt and the other women in their swimsuits, leaving him too embarrassed to climb out of the pool. His aunt notices and calmly slips a hand below the water to stroke him. Her breathing soon grows heavy, her expression turns lustful, and she guides his hands to her breasts and pussy. What began as a discreet handjob becomes genuine arousal. Unable to resist her lead, he penetrates her underwater, growing harder at the thought that anyone might catch them. An accidental erection turns into forbidden sex with his aunt right in the pool.
