We were just a couple of horny teenagers, my girlfriend Jenny and me. It was a school day but we had skipped and gone to the beach to get away from our parents and siblings and enjoy some time alone with each other. But no sooner had we set up our blanket near the dunes than a middle-aged man decided to set out his towel only about fifty feet further up the beach. I was bummed that he was going to put a damper on our activities but was determined to push my alone time with Jenny to the limit regardless.

Jenny was beautiful. Slim and curvy in all the right places, beautiful, wavy brown hair down to her shoulders, bright green eyes and a very pretty face with a sweet, shy smile. It constantly surprised me that she would let a skinny kid like me touch her amazing body, but to my delight she sometimes did.

Jenny lay on her front. She wore her secret bikini, that is, one her parents didn't know she owned. It was yellow and showed plenty of skin. The triangles over her breasts showed lots of side boob, especially as she lay there on her front. Her bottoms were supposed to cover her ass crack but as I took my time to work the sunscreen into her ass the fabric gradually slipped between her cheeks until it disappeared, leaving her ass totally bare.

"That guy is watching us. Watching you," I leaned over and whispered in her ear.

"And I don't blame him. You look naked," I continued.

"I feel naked," Jenny replied, eyes closed and smiling sweetly.

"Well, if you look naked and you feel naked you may as well be naked."

"Hmm. May as well," Jenny purred into her arm.

Well, this was new. Jenny had let me get to second base several times but was I hearing right? Did she just give me permission to take at least some of her clothes off here on a public beach where not only I but a strange man would see her? I wasn't sure how I felt about that but the erection straining against my swim trunks urged me to take advantage of whatever possibilities I could. In fact, as I thought about how Jenny looked, what she would look like naked, I started to get excited by the prospect of showing her off to the watching stranger.

Slowly I tugged on the ends of the little bows holding her bikini bottoms on. In my peripheral vision I could tell the man was watching us but trying not to make it too obvious. I left the ends hang there a moment while I massaged Jenny's bum some more. Then I peeled her bottoms down between her cheeks. She shifted a little, opening her legs slightly to make it easier for me.

I couldn't see from my angle but I thought that if I were in the right position I would actually be able to see those parts of her that so far I had only imagined. The stranger actually had a better angle than me but not quite good enough to be able to see Jenny's pussy either.

I resumed Jenny's bum massage, enjoying the feel of her silky smooth skin and pliable flesh under my hands. I had already applied the sunscreen to her back, but that was before her "invitation" so I slowly worked my way up her back and shoulders and then back down to where her top was tied.

Tentatively I pulled on one end of the bow. Only after the tie was undone did Jenny react.

"You're so wicked," was all she said.

Like with her bum, I couldn't see much more than I had before but just knowing that she was now lying there naked in front of me ... in front of us ... was such a turn-on.

I worked my way over her back to her sides and rubbed a good deal of cream into her side boobs. As I moved on I wondered if, and how, I was going to get a chance to do the other side with the stranger so close. Probably not, I concluded.

I worked my way down over her bum and down her legs to her feet. Of course this gave me an excuse to reposition myself and I wasn't disappointed when I stole a glance up between Jenny's legs and glimpsed the puffy lips of her beautiful bare pussy. My cock was so hard, straining against my shorts now that its ultimate target was in view.

After spending far too much time on her feet, I worked my way up her legs and started massaging the cream into her thighs. As I started to concentrate on her inner thighs Jenny opened her legs wider. I could detect her breathing becoming heavier as my fingers crept closer to her pussy.

Finally I touched it. Jenny purred and bent her knee, giving me a glorious sight and free access to her pussy. As I started to play my fingers over her soft, glistening folds I wondered what our neighbor could see now. I was pretty sure he still couldn't see what I could, although he would certainly be able to tell what we were doing. That's when he stood up and walked toward the water.

Suddenly he turned right so his path would take him right past us, only a few yards from the end of our blanket. Acting on a sudden impulse I moved my hands back onto Jenny's bum so I wouldn't block his view of her pussy. I didn't look at him as he passed but I'm sure he didn't resist having a nice long look at Jenny - who wouldn't?

After he walked by I heard Jenny's sweet voice. "That was so hot," she sighed.

Who is this girl? I thought.

"Maybe you should flip over so I can do the other side," I suggested hopefully.

"I don't think I'm going to do that," she replied. But while she spoke she shifted her position so that now she was lying on her side, facing me. Her head rested on one arm while the other was bent and shielded her nipples from my view. Her top leg was bent with her knee touching the blanket, her top leg shielding her pussy from my sight.

Though I couldn't see everything, I could see a lot, and every bit of her was lighting every bit of me on fire. She looked incredibly sexy, so soft and vulnerable.

As I lay facing Jenny I glanced over my shoulder and noticed the stranger had turned and was heading back our way. I turned back and saw that Jenny had propped her head up on her hand and was also watching the man approach. The way she was using her bent leg to shield her pussy from me was going to leave it fully exposed to the stranger when he passed by, including from where he had been sitting before. Jenny and I locked eyes and she smiled.

"What're you thinking?" she asked sweetly.

I smiled back and stroked her cheek. "I'm thinking of what a fantastic view that guy is going to have in a minute," I answered.

"I'm sure he won't look," she said.

"I'm sure he will. I know he will," I replied.

"Would that bother you?" Jenny asked.

My grin widened as a mischievous thought entered my mind. I lowered my hand to Jenny's knee, the one that was shielding her pussy from me. Gently I put my hand behind it and pulled it up towards me. It was now bent at more than a 45-degree angle leaving her pussy fully exposed from behind.

"You're soooo bad!" Jenny laughed.

"You know I've never seen you down there," I said, eyebrows slightly raised, as if I were telling Jenny something she didn't already know. "And now when he looks back, this stranger is going to see your bare ass and your bare pussy."

"No, he's not," she giggled. "He's not even going to look at me."

"Oh yes, he is," I retorted, with a chuckle.

"Well ... if he does then it's only fair that I let you see me too."

"Now that ..." I said, planting a kiss on her forehead, "...is something to look forward to."

Jenny lay her head back down on her arm. Her sparkling eyes shone up at me, a shy smile on her lips. I removed my hand from her hip and moved a bit to make sure she could watch the stranger approach. I watched Jenny's gaze shift from me to the stranger. She watched him walk by until he was behind her and out of her field of vision.

"Is he looking?" she asked me, whispering. I didn't look his way but I could see him in my peripheral vision. I nodded.

"He stopped. He's looking around, glancing at you while pretending to look up and down the beach," I whispered. "Now he's just staring."

Jenny closed her eyes and I could hear her breathing deepen. I tried to imagine what she felt like showing off her virgin sex to this strange man. I was looking forward to seeing, feeling, maybe even tasting how wet it made her.

"I'm so bad," she said, her eyes still closed.

"You're so sexy," I said, gently taking her arm and moving it onto her hip. Her breasts no longer hidden from me, Jenny opened her eyes and watched me looking at her tits for the first time. Then she straightened her leg and rolled onto her back treating both me and the stranger to the sight of her nude body from head to toe.

"Wow!" was all I said.

"You like?" she asked.

"I love!" I replied, leering at her for a minute before leaning down and licking her lips before kissing her.

While we kissed Jenny put both her arms behind her head. I held her wrist in one hand and ran my other from her cheek over her shoulder and down her arm to rest on her hip. I chanced a look at the stranger and saw him standing near his blanket, holding his phone as one would when taking a video. When he saw me look he turned it away as if he was just scanning the whole beach.

I turned back to Jenny and moved my hand from her hip onto her rib cage and then up under her breast which I cupped and lifted.

"He's filming you," I said, again taking her lips in mine before she could reply. I felt her grip my hand tightly as if to make sure I didn't move and spoil his view. As we kissed my free hand roamed over her body. I caressed her breasts, cupping and fondling them, pinching and twisting her nipples.

I slid my hand lower, across her flat stomach and smooth mound to her pussy. Just tracing her puffy lips with my fingers I could tell she was soaking wet and wide open, her pussy aching for more contact than the light touch of my fingertips.

"Oooh, you're killing me," she breathed through clenched teeth. She moved her hips, her pussy desperately seeking the pressure of my hand. But instead of giving it to her, I withdrew it.

"Hmm, hmm," she pretended to cry. "If you don't touch me I'm going to have to take matters into my own hands."

"I didn't think you could look any sexier than you do now, but that would probably do it," I replied.

I moved so there was a small gap between us and propped my head on my bent arm to watch. The stranger was standing next to our blanket, blatantly filming Jenny as she took her hands from behind her head and slid them down to her breasts. She squeezed them and tugged her nipples before lowering her hands to her pussy.

Her arms along her sides gathered her breasts together making them deliciously full and round. With one hand she held her pussy lips open as she began playing with her clit with the other. I watched her look right up into the stranger's camera. Her mouth open, breathing in gasps, she watched as the camera recorded her orgasm.

"Ooohhh," she looked at me and sighed as it subsided.

"Kiss me," she said and I obeyed.

When we broke our kiss I glanced down to see Jenny's legs spread, both hands holding her pussy wide open, and the stranger now kneeling between her feet, camera still greedily capturing everything Jenny offered it.

"So sexy," I said, kissing her lips again.

This time when we broke our kiss she looked into my eyes and asked, "Are you touching me?"

I showed her both my hands and her eyes widened.

"Is he ...?" I asked.

"Yes!" she gasped and then started whimpering.

I looked down and saw Jenny's whole body moving, her tits jiggling deliciously, as the stranger thrust at least two fingers in and out of her vagina. Incredibly he was still filming with one hand even while he pounded Jenny with the other.

I sucked Jenny's tit into my mouth and molested the other with my hand. This sensory overload was soon too much and spilled over into another orgasm that seemed to cascade up and down her body several times before subsiding.

As soon as she could speak again Jenny looked at me and implored, loud enough that I was sure the stranger could hear.

"I want him inside me, I need it! But you first. It HAS to be you first!"

What could I say? I looked up and down the shore to make sure it was still only the three of us nearby and then slid my shorts off and got between Jenny's legs. I knew she was a virgin, as was I. I didn't know much but I knew to go slow and I did. With Jenny so aroused and desperate I only noticed one small grimace on her face as I slid all the way into her.

Of course I was so aroused I lasted all of thirty seconds. Sliding in and out of Jenny's soft, wet, tight pussy while looking at her tits and gorgeous face gave me the most powerful orgasm I had ever experienced in my short life.

Jenny hadn't come. It was too soon since her last orgasm and I had been too fast. I slid out and we kissed. I slid off to the side and we both looked at the stranger. Without a word he dropped to his knees between Jenny's legs and pulled his shorts down over his erection. He handed me his camera and I began to film as he began to slide his cock in and out of Jenny's beautiful pussy.

I captured it all, the expression on her face when he sucked her tits into his mouth. The rise and fall of her chest as he picked up his pace. Her butt clenching as she thrust against him. And her silent scream when she came as he poured his seed into her body.

I kept filming as the stranger dragged his tongue down Jenny's body to her pussy and started to clean her with his tongue. As he lapped up the cum from all three of us I heard Jenny start to moan. When he took her clit between his teeth she started to whimper. When he started to flick the little nub with his tongue she started to come, again.

He kept licking her long after her orgasm had subsided. I guess he knew this wasn't likely to happen again and wanted to make the most of it. Finally he got up, pulled up his shorts, smiled at us, retrieved his camera and went back to his blanket where he sat, no doubt watching the video.

Exhausted, Jenny and I both dozed off with towels draped over our hips. When we woke he was gone but there was a note. It had an email address and just said: 'If you want a copy.'

It was only afterwards that I took stock and realized that this strange man had given Jenny three orgasms and I hadn't given her any. To my delight she spent the rest of the summer letting me shift the balance far in my favor.
