I'd been absorbed by the story the girls were telling me, and when I looked up I realised we were already pulling into the car park at the beach.

The sun was high, and the sky was blue. It was a beautiful day, and I was feeling great having three pretty girls to show me around. It's certainly not how I thought this holiday was going to go.

We clambered out of the car into the heat, stopping to grab towels, drinks and my camera gear before stumbling out onto the hot sand. Jandals really aren't the best way to prevent contact with sand, and we had to dance around a bit. It was a nice beach though, and not too crowded as yet. We had parked down towards one end of the wide expanse of sand, and between us and the water were a number of smallish sandhills.

We decided on a course through the dunes, and traipsed along, chatting about nothing until we stumbled across another group of people. It turned out that they were friends of Heather's from school, and we stopped there, throwing down towels and sharing cold drinks with the rest of them. They seemed like a nice enough bunch of people, though none of the girls were as pretty, to my eyes at least, as the ones who had brought me here.

The sun got hotter and hotter, and eventually someone suggested we should all go and cool off in the surf. I was keen to join that group, but didn't want to leave my camera gear here by itself, so I told them I'd hang out here and watch everyone's stuff.

It took no time at all for Steph to voice an opinion. "Not by yourself, you won't, buddy."

Vicki wasn't far behind. "No. We'll stay. You guys go. Make sure Heather gets a good dunking, okay?"

I protested, feebly. "You girls can go. I'll watch your gear."

"You can't, Paul." Steph turned to the rest of them then. "He's a pervert. He'll be hunting through your bags for your underwear if we leave him."

"I will not!"

"Not the guys, though." Vicki couldn't help herself, giggling with her hand over her mouth. "He's only a girl pervert."

"Yeah. Not queer, just sick."

"Yeah."

"Oh, will you two stop it."

"No. We won't."

"No."

"Oh, alright. Alright, stay."

Heather was looking worried. "Paul, is it alright...?"

"Oh, go, go. Can you take these two with you?"

"Ha ha. No. They're like cats. Don't you know yet? They can't be herded."

"I'm realising."

"I promise I'll look after your gear when we get back. Then you can take them and drown them. Especially Vicki."

"Hey!"

"Well, you told them to dunk me."

"Did not!"

Heather looked over at Steph for confirmation. "Yeah Vicki, you did."

"Can I blame Paul?"

"No. Hmmm. Paul, thanks for looking after my cousins." With that Heather knelt on the sand and kissed me. A quick peck, but on the lips. "And don't," she whispered to me, "let them lead you astray."

"No?"

"Uh uh. I don't want to miss anything."

"You are bad."

"And you, my new friend, are slow."

We watched Heather jump up and run after her friends.

"Nice ass," Steve mumbled at her receding back.

"Yeah, it is," Vicki agreed. "Isn't it Paul?"

"Yeah. Yeah, you're right."

Steve knew an opportunity when she saw one. "So, what about us, Paul?"

"Don't do anything Steve, please."

"You'll be embarrassed?"

"It seems likely."

Vicki had an idea then. "Tell you what. If we lie down, would you put sunblock on us both?"

"Oh, good idea, Vic."

"Yeah, alright, of course I will." Who was I to turn down an opportunity like that?

Steve moved the towels around so that the girls were lying in bikinis on either side of me, sky blue for her, and her sister in black. She handed me the lotion, and undid the strap on her bikini top, ensuring that I got a chance to look at her breasts before she lay down again, a mischievous grin on her face.

I smiled back. She really was lovely, if a little unpredictable. I looked over to find that Vicki had undone her bikini in the same way, and they were both lying there effectively topless. I hurried to do something useful with the lotion, well aware that my interest must have been obvious, given that I could feel my cock pressing against the cloth of my shorts.

As I knelt beside Steph, trying to will the evidence away before she saw it, I uncapped the lotion and squirted some on her back. She jumped with surprise as the still cool sunblock touched her skin, and her chest came up off the towel, revealing her breasts once more. She fell quickly back again though, her grin accusing me of having done it on purpose.

I began to rub the lotion into her back, and then she stopped me, pulling my head down so she could whisper to me. "Paul, that's not the way to do it. Sit astride me, and your hard-on won't be so obvious. Except to me!"

The comment was supposedly private, but Vicki started giggling and then Steve joined in. I couldn't think of anything to do but comply, so after glaring playfully at Vicki, I turned back to Steph, ready to lift my leg over her body and do this the way she wanted. Somehow, while I was looking at Vicki, Steph had managed to pull the back of her bikini down off her bum, revealing her slightly more pale cheeks to both the sun and me. I stared at her, and said nothing, moving to crouch astride her, covering her bare ass with my body, and ignoring her complaints.

She calmed down quickly as I rubbed the slippery lotion into her back, kneading her shoulders for a while, and then concentrating on her spine. Finally I moved down, and decided to take a little control here.

I took hold of the thin straps at the side of the little blue bikini, and pulled them down further, off her hips and down near her knees. I squirted some more lotion on her cheeks, and rubbed it in with the same dedication I'd shown further up her body, delighting in the sighs and squirms of pleasure.

My erection was giving me some serious trouble by now, and I was forced to rearrange things, wriggling my shorts around in hopes of getting a little comfort. It wasn't terribly successful, and started the girls giggling again, to my embarrassment.

Steve, as shameless as ever, rolled over underneath me, her arm slung over her bare breasts until she had a chance to spread the wisp of bikini top over them, but her thighs bare under my butt. She certainly wasn't helping, but she sat up then, gave me a proper kiss to thank me for the massage, and pulled my ear to her mouth again.

"Paul, you're lovely, did you know that?"

"Oh, thanks."

"But..."

"Oh oh."

"...You are being rude."

"Huh?"

"Aren't you going to put some of that lotion on Vicki before she burns?"

"Oh, I... yeah, but... I've..."

"Yeah, got a hard on. She's seen those before."

"Shhh..."

"No, really." She turned her head to Vicki now, and raised her voice a notch. "Hey sis, ever seen an erection?"

I looked over at her as she started to laugh again, and noticed that her bikini was also pulled down off her bum, her pale cheeks more noticeable than Steph's had been. I turned back to Steph, completely unsure now. She whispered some more.

"Look, Stud, it's okay. Really. Stop looking so terrified."

"Yeah, but..."

"I don't own you, you know. And Vicki and I have no secrets. Just go do what you did to me. She'll love it, and so will you."

"You sure? I don't know how to deal with you two. I'm always..."

"Confused. I know. Relax."

"Yeah. Maybe."

After thinking for a moment, I couldn't think of a good reason not to follow her advice, and hell, when was I going to have another opportunity like this? I lifted myself off Steph's butt. When I started to pull her bikini back up she stopped me, professing a need to tan her cheeks, and turned over again, but not before giving me another good look at her breasts, and a quick kiss.

Vicki stared dreamily in our direction all through this, and lifted her eyebrows at me as I approached on hands and knees, ensuring I touched only the towels. No one wants sand rubbed in their back. She didn't object when I sat astride her in the same way as I had with Steph, and she didn't jump when the lotion hit her back.

The two of them kept up a mindless chatter as I spread the lotion in, repeating the same shoulder rub, and the same slide of my thumbs up her spine. In the end, I relaxed to the whole thing, realising that Steph wasn't going to make any sort of fuss, and when I finished with her back, I slid down her body a little more, and squirted sunblock on her pale buttocks. This time she did jump, and didn't take any more care to cover her breasts than Steph had. I stared.

As she relaxed back on the towel, and continued talking to her sister, I rubbed the lotion into her cheeks, careless now, and not worrying. Vicki reached down herself, and pulled her bikini down her legs, out of the way, to a chorus of giggles from both of the girls. Neither of them had taken any care to keep their legs together, and though I'd seen Steph in that sort of state before, it seemed a much bigger deal with Vicki, and Steph asked if maybe I needed some emergency lotion myself, as my face had gone bright red. I said nothing. I might have been embarrassed, but much more than that I was highly aroused, and my cock was painfully trapped in my shorts. I'd have done something about it, but I was too shy now to manage it.

As I finished rubbing lotion onto the second lovely girl's ass, and lifted my hands from her, she surprised me a little by turning over the way Steph had, ignoring her bare breasts and thighs, and pulling me down on top of her, and thanking me with a thorough kiss. I was hesitant for a moment, and then, after quickly peeking at Steph's expression, made the most of it, pulling her face to mine, and letting her decide how much of my mouth to explore with her tongue.

I was barely able to think at this point, and when Vicki let me go, I wasn't quite sure what to do. I sat there for a moment, in the hot sun, and then Vicki wriggled a little up the towel, and sat up. Not waiting for any sort of confirmation, she reached her hand down my shorts and pulled the front of them forward. My tormented cock bounced to a near vertical position, and as she released the cloth again, the tip of it poked from the band of my shorts, a drop of liquid on its very tip professing how wound up I was. Vicki looked at Steph, and then back at me, wiped her fingertip carefully across the drop of moisture, and lifted her finger slowly to her lips, watching me intently the whole time. It's a wonder I didn't come on the spot, and spurt all over her bare chest, but somehow I held off.

Just as Vicki was about to say something, there was a bustle of noise between us and the water, and we realised the crowd was returning from their swim. I didn't know what to do, and in the end I just lay down on my stomach over the towel between the two girls, and pretended not to hear them both laughing heartily. I didn't know girls like this even existed!

Heather showed up and told me we could go for our swim now, and she'd watch our gear. I made some feeble excuse and stayed exactly where I was, while she looked at the laughing sisters with some confusion.

Eventually we were left where we were as Heather joined her friends to toss a ball around on the sand, and the three of us lay there and soaked up the sun. The girls had managed to pull their bikinis back up as the crowd arrived, and no one had said anything. After a while, Steph poked me in the ribs.

"Well, better now?"

"Better?"

"For walking."

"Oh, yeah, I think so."

"You can't tell?"

"Well, it's kinda... well, not hard..."

"But not really soft?"

"Yeah."

"Turn over."

I looked around to see who could be watching, and then did as she asked. "Well?"

"Nah, you're fine. Hey?"

I looked over again. "Yep?"

Steph turned and sat up suddenly, shaking her bare breasts at me before putting the bikini top back in place. "That," she said to me, "is just flirting."

"It's damn near rape."

"Only if you resist."

"I couldn't, Steve."

"That's me off the hook."

I stood up and looked over at Vicki. She'd managed to put her bikini back in place as well, and we all stood up and flicked sand off our bodies. "So girls, could you do me a favour and let me get to the water without embarrassing me again?

"Maybe."

"Could be."

"Or maybe not."

"Yeah."

I sighed and tried not to take too much notice. I'm not sure I succeeded, but we did manage to get to the surf without any embarrassment. I'd stopped on the way to make sure Heather would keep an eye on the camera, but in the end she'd asked someone else to do it, and had come with us. Once again, I had a complete harem. And a desperate need for some sort of release.
