It took about a day for the Major to get her thoughts organized. The girls were scattered in little groups, wandering around, talking. Sheila pretty much stayed in my tent, looking after me, holding me, making me feel good. We made love that night in kind, gentle ways, holding each other when we came, cherishing one another, healing each other. Was she establishing a claim? I don't know and I wasn't smart enough to think it through. Mary and Jenna came by the tent later, and while Sheila was friendly, she was not letting them in. I just sort of basked in the glow of being taken care of, being pampered.

The next morning, Sally came by and shook the tent frame. I noticed she was wearing her t-shirt now to prevent me from ogling her breasts.

"Hey, Sheila! Come on up to the shacks. The Major is having a meeting. Let's go!"

I stuck my head out.

"What gives?"

"Not you, Mark," said Sally, laughing. "Girls only for this one." Sheila exited the tent, wearing only her shorts, and disappeared up the beach with Sally.

I loafed around, fishing, tidying up the area around the tent and cutting up some coconut logs for firewood. About three hours later Sally came back down, without Sheila.

"I can give you the low-down on the meeting," she said. I pointed to a stump near the fire pit and we sat down there for a chat.

"So, it was pretty interesting, that meeting," she said. "Planning for the future, that kind of stuff."

"Why wasn't I invited?"

"The Major thought you might be a distraction. Quite a bit of the discussion was about you, actually."

I offered Sally a mug of coffee, made out of one of the last packets from the survival kit. She took a sip and thanked me. Then she held up the cup.

"This is kind of a symbol of the future. We've been here, what, six weeks now? Just about all the supplies we brought with us are starting to run out. We are going to have to shift to relying on what we can find or produce here. That was the Major's big point. We have to shift to a long term focus. We may not see rescue for years, if ever."

That thought had been crossing my mind also. We were here for a long time, in any plausible scenario.

"So, the Major is refocusing our efforts from preparing for rescue to enhancing sustainability. The sergeant is taking a skills inventory of the girls, finding out who grew up on a farm, who made soap as a hobby, who can sew, that kind of thing. But you can find out the details from the Major herself. She wants you to have dinner with her, and she'll lay it out for you."

That surprised me. But, there were more surprises in store. Sally spoke again.

"A big change, as far as you're concerned. No more intercourse. Nada. Zip!"

"What the hell, what's up with that?" I felt as if someone had hit me with a sledgehammer.

"Well, if you remember my comment about supplies running out? Birth control is just about done. The Major asked the girls if anyone felt it was safe to have a baby out here, and Sheila was the only one to raise her hand. No one wants to risk a pregnancy in this isolated environment, far from a hospital or a doctor. So the decision was made, and agreed to, no more fucking for Mark." Sally smiled at my discomfort.

"That doesn't mean no sex, though," she said. "The rule is, anything but riding your dick, and always two girls involved so as to prevent one from getting carried away in the moment. The best combo is actually one straight girl and one lesbian. The Major recognizes your contribution to our future is important, and she wants you to be happy. The girls don't want to miss out, either."

I wasn't happy at the moment, and it showed.

"So, I'm the stud on call, then? A morale facility for the girls?"

Sally gave me a serious look.

"Mark, you have no idea how much pregnancy terrifies these girls. At the same time, we're all young and horny, so if there aren't any restrictions put in place the outcome is inevitable."

"You're young. Are you horny?" I gave Sally a sly glance, still remembering the feel of her naked breasts against my chest.

"You bet! Just not for you, though. The sergeant and I are getting along just fine. She's not as severe as you might think. And, she knows her way around a woman!." Sally laughed. "Why, do you want a blow job or something?"

"Could do," I said hopefully.

"Hmm, show me your man meat! I might lose control and forget my preferences!"

"Fuck off!" I said, laughing. I deserved that one.

Sally laughed. "I used to do that in high school, before I found my true self. So, maybe you might get lucky when I'm on escort duty for one of the straight girls one night. But, I think you should save yourself for tonight, for dinner with the Major."

"What do you mean? It isn't just dinner?" My puzzlement showed on my face.

"I think the lady wants some sugar from Captain Mark," she said. "Just a hunch, but a girl can sense these things. Do you have any condoms left? You might bring one, or two, just to be on the safe side!"

Sally drained the coffee, then looked at the cup the way you do when you realize you're not going to see something again for a long, long, time.

"Thanks for the coffee, Mark. Dinner's at seven in the Major's hut. I'll see you later."

Sally walked back up the beach, and as I watched her shapely ass recede from sight, I pondered what the Major had up her sleeve. Dinner!

That evening would prove to be one of the stranger nights of my life. In preparation I bathed in the ocean, and wore my best t-shirt and shorts, since I had nothing other than my flight suit in the way of clothing. My hair was getting long, so I combed it out neatly. My razor had long since given out, so a stubble graced my chin. I was really starting to look the part of the castaway!

I appeared at the Major's hut at 7 p.m., as advised. The sergeant opened the door, and I had my first shock of the evening. Until now I had only seen her in her baggy combat uniform, with a hat squashed on her head. Now, she wore a light sun dress, scooped low to display an impressive set of tits. Her hair was strawberry, and the sun had brought out a host of freckles on her cheeks and button nose. I figured she was about thirty, and although she was a bit thicker than the younger girls, she was about 5 foot 8 inches and had an excellent figure.

"Well, hello, sir," she said. "Come in! The Major will be with us in a moment."

"Call me Mark, please," I said. "That's a lovely dress, by the way. Suits you!"

The sergeant blushed a little. "Since we're being informal, Mark, please call me Dianne. And thanks for the compliment! The Major and I made sure we had some casual clothing in our baggage for when we might have some time off. So, it's come in handy!" Dianne motioned to some rickety chairs by a table that had been set with a groundsheet for a tablecloth. It was already getting dark, but a couple of lanterns glowed by the walls. I noticed a thin mattress in one corner, covered with a light blanket.

"You don't sleep here, do you?" I asked.

Dianne shook her head. "No, of course not. Sally, I mean, Lieutenant Morton and I share one of the other shacks. The Major sleeps in one adjacent to here, and this serves as a sort of office. We've salvaged some furniture from the old abandoned buildings and fixed it up a little, that's all." Dianne flashed a seductive smile, and I wondered what was up?

The Major arrived, wearing what I figured was a sarong. It was a lovely, light purple fabric wrapped around her body, with a tie below her bosom. The garment flowed down over her legs, but with a slit that allowed freedom of movement. Her blonde hair was starting to grow long, and it straggled around her neck. She flashed me a smile, pushed her glasses up her nose, as she always did, and did a bit of a twirl with a seductive wiggle.

"Well, what do you think? Bit of a change, right?"

I could hardly take in what I was seeing. This was the hard-ass Major, now admitting she was a woman, and being proud of it. I drank in her luscious form. She was a bit chubby, though thinning down now, as we all were, from the short rations. Maybe 5 foot 4 inches, and a bit wide. But, her large breasts showed plainly through the thin fabric, and looking at her hips, I couldn't detect any panty lines.

"Wow, ma'am, you are looking fine tonight, I must say. I'm a bit ashamed of my own lack of suitable dress at this moment."

She smiled at me. "It's kind of informal tonight, so just call me Natalie. That's what my friends call me. I'm not happy about the hair, though" Natalie twirled some of her blond locks with her fingers. "The sea water plays hell with it. I'm thinking of braiding it, like some of the girls have done. Much easier maintenance!"

I didn't know what to say to the hair comment. I was a bit uncomfortable standing between two women who, if I'd thought of them at all, always seemed to be sexless bureaucrats. Now their milfy-ness was revealed, I did not know what to say.

Dianne giggled at my discomfort. Natalie smiled and indicated a chair.

"Let's sit down and have a drink. Dianne will get us something. I always have a stash when I travel and I still have a little bit left."

We sat down, and I admit I had some difficulty in not letting my eyes wander down to her tits, which were pretty much on display. Natalie had a soft face, not beautiful, but pleasing when she chose to relax it and smile. Dianne returned with a tray of drinks.

"Vodka mixed with a little papaya juice," she said. "No ice, I'm sorry, Mark" Her face gave a sweet pout.

I tasted the drink and nodded my approval. Natalie put on her serious face and became the Major for a moment.

"I know that Lieutenant Morton updated you on the meeting. I apologize for not having you there, but these girls, they are great technicians, but they are silly. They lack the life experience that you and I share. I had to bring them to understand a few things about our future here."

"No, I get it," I said. "We have to think long term."

We chatted through dinner. Dianne brought out grilled fish, coconut and papaya, with a bit of stewed crab. This was pretty much our standard diet by this point. Dianne joined us, and also kept the drinks flowing. Natalie recapped her plan, which accorded with what Sally had told me. More drinks, and I began to get a bit of a buzz.

"Where's Sheila?" I asked. "I haven't seen her today."

Dianne answered. "Natalie sent Sally, Sheila and a couple of others out on a reconnaissance mission. We haven't really explored the island fully, and we've got to find out what's out there. There could be more water, food, even relics from previous habitation that might prove useful. They'll be gone a couple of days." Natalie nodded approval.

I noticed that when Dianne got me a drink, she made a point of bending over in front of me so I could look down her dress. As we ate, she kept brushing her hand against my thigh under the table and giggling. As Natalie got a few more drinks down her, her smiles became more seductive and her eye contact longer. She even made a joke about her breasts!

"I wasn't sure I'd be able to get these things into this outfit," she laughed, pushing up her tits for my benefit. "They look alright, don't they?"

They certainly did, and I said as much. Natalie grinned and Dianne laughed. More drinks appeared.

"Let's talk about sex, then," said Natalie, a little drunkenly. "Let's talk."

I was all ears

"So, as you heard, I told the girls no more shagging the stud down on the beach. And you know why? They're all young, and will get pregnant, and before you know it we'll have babies running around. Plus, they are all scared shitless of childbirth here out in the middle of nowhere. So, I told them, it's fine to fool around, but no more intercourse. There has to be safeguards!"

I nodded in agreement. Natalie leaned over, her tits almost spilling out of the sarong and fixed me with a stare.

"Are you going to miss screwing them? Are you, Mark?"

Of course I would miss it! I said as much.

"Well," said Natalie, her eyes twinkling, "we've got a proposition!" Dianne giggled and rubbed my thigh gently, almost squirming out of her chair. "You can have sex with Dianne any time you want!" Natalie sat back with an air of satisfaction, her tits jiggling. "Dianne, you want to explain?"

Dianne laughed. "Sure! I'm pretty free sexually. As you know, I've been with Sally since we got here, and that's been great. But, I do go with men on occasion, and I like that too! But, here's the good part. I never wanted children, I just wouldn't be a good mother, I don't think. I mean, I love being an auntie and all, but to have, them? No! So, when I turned 29 I got my tubes tied. I can't get pregnant, I can't have children."

Natalie put on a serious, somewhat inebriated, face, and slurred.

"Your sexual health is important to us, Mark. We're here for you buddy!"

Dianne was obviously raring to go, but I got the feeling that Natalie wouldn't mind a little Mark in the night either. So, I asked her.

"What about yourself, Natalie? You're a good looking woman, if I may say so."

Natalie giggled. "Yes, a good looking, fertile, woman. I can't risk getting pregnant either. It's riskier at my age. So no, at least not inter...inter..."

"Intercourse!" said Dianne.

"That's right, intercourse! Can't do it. But you two, well go ahead! I'll watch!"

I was about to say more, but I felt Dianne's hand sliding under my shorts, her face on my shoulder and her hot breath on my cheek. I turned and we began kissing. For a lesbian, she was doing a damn good impersonation of a woman who was horny as hell for a good fuck. She started stroking me and kissing, and I realized I had a real woman on my hands, a woman who knew exactly what she wanted. I reached up and pulled down the top of her sun dress. Her tits were milk white below the tan line, with puffy little pink nipples in the center of small strawberry colored areolas. I cupped them in my hands softly, running my thumbs lightly over her nipples.

"Nice technique, I like that!" said Natalie, with a slur. "You're welcome to use my little mattress over there, if you like."

Dianne rose and led me by the hand over to the mattress. She slipped out of the sun dress, and I drank in her womanly form, skin alternately milky white or reddish and freckled where the sun had tanned her. Tufts of reddish hair under her arms and in her crotch testified to the shortage of razors. We stood there, kissing and letting our hands roam over each other's bodies, both moaning with pleasure.

Natalie followed us over, and knelt to tug off my shorts, while Dianne pulled my t-shirt over my head and threw it in a corner. My cock was getting harder by the second, and Natalie started sucking the tip while Dianne and I continued kissing. I moved down onto her tits, circling her little pink nipples with my tongue and placing a hand between her thighs, gently pushing them open. Natalie started stroking and sucking vigorously, still fully clothed. I as getting weak in the knees, so pushed Natalie away from my cock, and drew Dianne down onto the mattress with me. Natalie backed off and sat on the floor watching as Dianne and I kissed and felt each other. I rolled on top of her and started to hump her mound without inserting myself, wanting her to get excited at the thought of my cock entering her pussy. She moaned and pushed against my thrusts. I was drunk enough that I didn't mind Natalie watching us. Dianne was thrusting her tongue into my mouth, sucking on my lips and moaning as I humped her. I was getting so excited that I knew that if I entered her, I'd blow my load right away, so I slowed the pace. I rolled off Dianne and sat up beside her. Reaching down, I spread her pussy lips and began to softly rub and pull on her lips, going almost as far as her clit, but backing off so as to build the excitement. Dianne rolled her head to the side and put her hands over her face, pushing her hips up against my searching hands.

I heard a low moan, but not from Dianne. Natalie sat on her bum, legs spread, pulling up the fabric of the sarong up to her hips. She had both hands between her legs, playing with her pussy while she watched us on the mattress. With one hand, she was slowly finger-fucking herself, while with the other she rubbed her clit in little circles. I kept my eyes glued to her moist cunt while my fingers explored Dianne's pussy. Now Dianne began to moan, and I had the stereo effect of two women building to orgasm at the same time.

Dianne won the race. She too began to watch Natalie play with herself, and became very excited. I wanted to taste that delicious pussy, so I lay between Dianne's legs, spread her lips and started tonguing and face-fucking her cunt. My bristly chin sent her into overdrive! Dianne began moaning like a cat in heat, and her hands pushed my head into her pussy. I began a gentle sucking of her clit, and Dianne responded with a massive orgasm, bucking her hips, moaning, thrashing and grunting. Her thighs clamped my head as I hung on. I could hear Natalie in the background, expressing her enjoyment at the sight of Dianne cumming and knew Natalie was not far off. Then Dianne pushed my head away and lay panting.

"Oh, it's too sensitive! Stop!" she said. "Oh my, that was strong!"

I turned and looked at Natalie, who was still finger fucking herself gently, and moaning. She looked me straight in the eyes.

"Fuck her now," she said. "Fuck her good! She needs a cock!" Natalie's face was a mask of drunken lust, and I knew she was wanting to watch me fuck Dianne so she could bring herself off.

I reached up to caress Dianne's milky white breasts and move up so my cock was just at the mouth of her pussy. Dianne smiled and gave me an expectant look. I held her gaze as I pushed my raging hard on past her pussy lips, and as it entered she closed her eyes and groaned. Her hands reached around for my ass and pulled me closer. I was ready to explode, but fought to control myself, stroking slowly with shallow thrusts, watching Dianne's face. She kept her eyes closed, her lips curved up in a smile and she emitted a low moan with each stroke. I could hear Natalie's excited cries in the background, and the rhythmic rustling of the sarong fabric as it brushed against her masturbating fingers. I couldn't stand any more.

Deepening my strokes and picking up the pace, I placed my full weight on Dianne and started to pound her without restraint. Over and over I fucked her with everything I had, grunting, thrusting, slamming my cock into her juicy cunt. Natalie cried encouragement beside us, and as I went for the paradise stroke the dam burst for all three of us. Intense cock spasms gripped my crotch as I shot streams of cum into Dianne, while she cried and moaned, her pussy gripping me like a vice. Natalie cried out, uttering unintelligible words and she too came under the touch or her busy hands. I slammed into Dianne's hips a few final times, and then rolled off her to the side, exhausted. Dianne simply lay there panting, while Natalie collapsed beside me. After a moment, Natalie gave me a gentle kiss on the cheek. Her hand wandered down to my slippery cock, but it was too sensitive and I pushed it away. After a few minutes we all cuddled together into a drunken, post-coital snooze.

We slept for a few hours, then I awoke to the feel of Natalie's lips on my cock. I looked around, and noticed Dianne was gone. Natalie continued to give me head, and I thought, 'what the hell, she can do what she wants,' and let her go as I lay on my back and enjoyed. She was still wearing the sarong, and I reached over and ran my hand up the slit to feel her pussy. It too was bristly, as hair was growing back in. Natalie was moist and supple, and I began finger fucking her as she sucked. She pushed her bum up so I could have better access, and started taking more of my cock into her mouth. The sucking and slurping were getting me excited, but since I had blown my load in Dianne earlier that night, I was in no rush. I paid attention to pleasuring Natalie, and she was obviously enjoying it, her bum starting to wiggle more as I thrust my fingers into her pussy. I got curious, and she was really wet, so I put in three fingers, then four, extending them in a cupped fashion so they could slip in. Her juices flowed over my slippery hand, and in another moment I had my whole hand up her cunt. Not very far, of course, but she was stretched right out as I pumped her. Natalie sucked harder for a few moments and then released my cock, simply laying on the floor and gasping.

"Ugh, ugh, oh god, oh god," she moaned. Natalie covered her face with her hands.

I stuffed my head under the sarong fabric, and the morning light let me see her puffy ass, with my hand sliding in and out of her snatch, with the purple cloth created the illusion that we were in some kind of tent. I used my other hand to rub her clit, and Natale came almost immediately, moaning like a whore as I pumped her with my fist. After a few spasms, she pulled off and rolled on her back on the floor. I crawled up and placed my cock head against her lips, but she shook her head no. Her tits were splayed out against the transparent fabric, nipples fetchingly visible through the semi-transparent fabric. Kneeling beside Natalie's chest, I jacked myself off onto her tits, grunting with satisfaction. She reached up and smeared the cum across the bosom sarong, giggling like a high school girl who just made her date cum in the bushes behind the gym on prom night. I gave her a quick kiss on the cheek, gathered up my t-shirt and shorts, and staggered back to my tent.

I slept until well after noon, then went fishing for a couple of hours, enjoying the sun and letting the memories of the previous night order themselves in the filing cabinet of my mind. I took some of the fish up to the shacks for the girls, but the Major and the sergeant were nowhere to be seen. Probably still nursing hangovers. At dusk I cooked a quick meal and then turned in. For the first night since my arrival on the island, no one came down to my tent looking for a shag, and I slept like a dead man.

In the morning the light was streaming through the tent fabric, and I rubbed the sleep from my eyes. In the first moments of emerging from dreamland to reality, I felt as if Sheila was under the blanket beside me. I could feel the warmth of her soft figure, the delightful heft of her heavy breasts, the light touch of her fingers on my chest. She mouthed a word, and after a moment I realized she was telling me she loved me. The illusion faded, but I felt warm and happy all over, and lay there in a state of bliss.

Suddenly, the tent frame shook, and I heard Sally's voice calling me to come out.

"Hey, Mark, wake up! Come on out for a second," she said.

I crawled out of the tent, my eyes blinking in the sun. The coffee was all gone, so I had to wake up the normal way. Sally stood there, with her t-shirt on. She was ashen-faced. Something was wrong.

"Hey, what's up?" I asked.

"I'm so sorry," she said. Tears rolled down her tanned cheeks. "It's Sheila."

"What? What about Sheila?"

"She's gone. We were on the other side of the island, camped for the night. In the morning she went into the surf to bathe, and a rip tide carried her out. We tried to go after her, but she got swept away so quickly, nothing could be done."

A black curtain descended over my eyes, and in a moment I was above the tent, looking down at Sally and a man I didn't recognize. He lay collapsed on the sand, crying in pain like a wounded animal, beating his fists into the sand. Obviously something very bad had happened, and I hoped that man would be alright. Then he faded from view and the world became silent and warm, as if I were inside a bubble.
