We'd been snorkeling for about 30 minutes off the coast of Hawaii when I decided I was a little bored with our favourite snorkeling spot. We came here often, because it was far enough away from the tourist spots that only locals really used it and then typically they were only spear-fishermen.
My wife was doing her usual snorkel session, diving deep down and peering under coral and rock formations, looking for interesting things. She would glance in my direction every now and then to make sure I was nearby and okay, but otherwise we were pretty much doing our own thing.
That's when the idea hit me.
While she was not paying attention, I whipped off by board shorts and threw them up on a nearby rock edge. My cock was instantly hard, because I'd never done anything involving nudity before and certainly had more than just swimming around naked on my mind.
From then, I went back to pretending to be snorkeling normally. With my wife periodically glancing back, she mustn't have been really paying attention because I saw no reaction.
Over the next 20 minutes, the hardness of my cock varied greatly. If I was thinking about my whole nude snorkeling experience, I'd get hard pretty quickly, but whenever I focused on the ocean and my surroundings, I'd gradually go soft again.
My wife continued to pay no attention.
A couple came snorkeling by, presumably some tourists who had gotten the inside scoup. The woman saw my bare ass and pointed to her friend, I could see them both laughing through their snorkels.
I thought I saw a turtle head under a rock formation, so I dove down deep and grabbed onto the edge of the rock. As I pulled myself down and shoved my head under the ledge, I suddenly felt a gloved hand slide up the back of my thigh to cup my ass as another bare hand felt around to my front to grab my limp cock.
Turning my head suddenly, I saw my wife peering at me through her dive mask. We held our positions, somewhat oddly upside down on the edge of some lava rock underwater as her hand massaged my cock to hardness.
Running low on air, I pushed off the rock and turned to shoot back for the surface. My wife always had better lungs than me, so she let me go and slowly rose up to join me. As I gasped for air and she surfaced beside me, she immediately grabbed my cock again and resume her slow stroking off it.
She spat her snorkel out. "I saw an eel down there near the rocks.", she said cheekily. I noticed her glove floating on the water behind her.
"Meet you back down there", she said and pushed back, letting go off my cock. She grabbed her glove and shoved it down her one-piece swimsuit between her tits. She wiggled her eyebrows at me seductively as she put her snorkel back in her mouth and I watched her flip around and dive down.
Taking a couple of deep breaths, I flipped over and followed her. She had already latched onto the rock at the bottom with her gloved hand and was motioning for me to do the same.
Never as elegant under water as she is, I tried my best and latched onto the rock, my body swinging about slowly in the current.
She wasted no time in wrapping one arm around my waist as she spat her snorkel out. Her lips engulfed my cock so easily that I almost blew my air out immediately.
So here we were, pretty much exactly where I'd hoped when I first ripped off my shorts about an hour before. I was clinging one-armed to a rock and starting to worry about my air supply as my wife clung to my body and delivered a fantastic underwater blowjob.
With aching lungs, I let go of the rock and tapped her on the head. She gripped my waist tighter and took my cock deeper, so I turned upward and did my best to kick my fins towards the surface, lifting both of us up as she continued to blow me.
I burst through into air and spat my snorkel, choking in air as best I could while my mind continued to focus on the lips sliding up and down my cock under the water. The question of how my wife was holding her breath flashed through my mind, but obviously I was willing to let her figure out her own needs as she deep throated me and licked my balls on each stroke.
It seemed like forever as I treaded water on the surface before she broke free and popped up to get her own air supply. She hardly seemed out of breath at all. "Salty" she said with a laugh and wiped her lips dry a little. She kicked back away from me with her own strong fin strokes.
"Okay, don't follow me down immediately, let me get set and then follow my lead", she said. I always knew she was more comfortable in the water than me, but I'd never have guessed she was this comfortable. She was taking control of our session just as if we were back home in bed!
