Scuba Retreat Day 2 - Secret Pussy Vibe During Lesson

Day 2 of the Kinky Splash scuba retreat and part 5 in the series. I am completely naked underneath my tight neoprene wetsuit with nothing but a secret vibe tucked inside my pussy vibing my gspot. The suit clings to every curve and the zip in the crotch area made it so easy to hide. Todays lesson is all about putting the BCD Kit on and off under the water and clearing the mouthpiece. Every time I move the neoprene rubs against my bare skin and the vibe presses deeper. I am biting my lip trying to focus on my regulator but the sensation keeps building. My legs are trembling in my fins and my breathing gets heavier through my mouthpiece. My instructor keeps asking if I am alright because I am clearly flustered and distracted. I barely hold it together for the entire lesson and the moment we surface I sprint to the fitting room leaving my instructor confused and calling after me. You will have to imagine what happens once I am alone behind that closed door.
