Scientist visits a very fertile island

Something on this island is very different. I haven’t felt the same since a bit after we arrived. I was always an example of ethics and conduct, and now here I am driving around sitting next to the woman I was meant to observe. I’d done plenty of observing, and plenty more, having just a few hours ago made love with Ali in a tropical paradise and now all I want is to do more of the same thing. Something on this island has changed me. It’s like the culture has been injected with sex, everything inviting naughty thoughts and actions. It’s rare to go long without seeing two people fucking their brains out; the men are avid lovers of the women’s’ pregnancy and the women themselves (most swollen enormously with pregnancy, bigger than a single term) happy to pleasure one another. But why? The hormones? I suppose it’s part of the reason, but even a multiple pregnancy doesn’t drive women into this kind of sexual overdrive. Maybe all of them together explains it. To test my hypothesis I asked Ali to drive me to the most crowded area around. Deep down I knew this wasn’t to sate my scientific curiosity, but my lust.
Ali knew exactly the place to go, setting her sights on the beach. There were white sand beaches with mild, bright blue waves crashing onto the shore and the hot sun beating down on the barely-clothed beauties. Big bellies were waddling about in revealing bikinis, showing as much skin as they could thrust into the daylight. The only one pieces I saw were the girls who had decided against bikini tops, their dark nipples pointing out like erasers on pencils. I was amazed at how collectively brazen these women were. At home no woman this gravid would consider herself sexy enough to parade around, so obviously fertile and fecund. But no woman on this island considered herself anything less than a goddess. Why should they, I suppose. They are treated like fertility goddesses, giving birth to the next generation in the lap of luxury.
Ali, sad she hadn’t brought a swimsuit with her, led me into the crowd, which was an experience by itself. Every belly I saw was round and smooth, ranging from modest to eye-poppingly enormous. I marveled at how many babies some woman must be carrying, and how close to (or even past) term some were. The packed pregnant beach apparently gave these women great joy, bellies bulging rudely from their figures up and down the beach as they tanned and relaxed and swam and frolicked with one another. I suspect under some of the shadier umbrellas and changing tents the frolicking and companionship had been taken to its inevitable conclusion. My head was swiveling so fast I tripped over my own feet when Ali stopped suddenly without warning.
Spitting out the grains of sand from my mouth, I shaded my eyes and looked up. There was no need; the sun was thoroughly blocked out by two moons rubbing against each other. I stood up and saw Ali hugging a nude pregnant woman, her belly swollen huge and round in front of her. They parted and began rubbing each other’s globes, talking about their pregnancies.
“That’s my girl Ali, always getting so big so quickly. Damn girl, you’re so pretty. And who is this? And why do you always have some new hunk on your arm?”
“This is one of the new scientists, here to study us.” They shared a look and a giggle at this point and it became more obvious that I could hardly expect a girl as obsessed with sex as Ali seemed to be to keep what we had done a secret. All I can hope for now is that my superiors somehow don’t find out. “Meet Brittany! She’s one of my best friends. And one of my roundest! Look at you, babe, all belly and boobs. Ah, I love it.”
Brittany took a step back and thrust her belly forward, hands on her lower back. I was hypnotized by her massive womb, especially since she was so obviously proud of it. It curved out from under her breasts and sloped out so far you couldn’t see her sex even though it was obviously bare. Her belly button had popped out and topped her tummy like a third nipple. It took me a minute to shake away from staring at her pregnancy to take in the rest of her. A brunette beauty, she swayed back and forth on her heels, which shook her bare tits slightly left and right, brown crinkled nipples rudely stuck out. It was obvious from her tan she spent a lot of time at the beach and from her lack of tan lines that her nudity was a habit. Everything about her was slight and thin besides her fat belly and big tits. I imagine she would be a thin girl if not for her pregnancy, one where she was very clearly carrying multiples.
“I know, I know. I’ve gotten pretty big this time. Weird it’s only two in here, I’m as big as when I had three! I’m happy though, I love this shit. I’ve been cumming like a hundred times a day. I swear my preggo belly is pushing on my clit. I gotta stop talking, I’m about to drip.” Wow, Brittany certainly got right to the point. I had never heard a woman speak that raunchily about sex, and it was a little shocking coming from a woman with an enormous bump. Apparently she was having twins, so with her girth she had to be close to delivery. I didn’t know much about the birthing processes here yet so I finally spoke up and asked her how far along she was. She smiled and patted her globe.
“Nearly there, forty-two weeks. Only a couple more! Not much left to do but relax and enjoy myself. I’m so big enough already. Don’t get me wrong, I love getting so fucking pregnant I waddle like a penguin but my babies are already twelve pounds each. Ugh, shoot me now. Kind of a catch-22, I love being pregnant but I still fucking hate birthing kid this fucking big.” Wait, had she said 42? I know pregnancies only last 40 weeks. Maybe this girl had it wrong? She didn’t seem like the sharpest tool.
Ali was a bit smarter than her friend and must have read the confusion on my face. “Pregnancies tend to last an extra month here. It’s part of why we keep things so stress-free. We also have such great diets, they’re really great about giving us what we need.” This was the kind of thing I needed. I made a note to check into specific dietary needs at my next convenience. Now my day was yielding the results I’d come for. When I looked up, Brittany was waddling as fast as her swollen feet could take her toward the water, Ali right behind her and stripping off her top to join her. They splashed into the water and began a playful game of belly tag, grabbing each other and moving effortlessly in the warm water. I stopped to take notes of what I was seeing around the beach specifically, including a girl laying out sunbathing who was massive enough to warrant a beached whale comparison, a girl walking out of one of the changing tents wiping her mouth as a grinning man walked out behind her (gee, I wonder), and two girls near Ali and Brittany giggling as they shot their milk at one another. When I looked up from my book, Ali and Brittany were waddling up the beach hand in hand. Brittany looked back for me, and yelled that I better hurry up and join them. Not wanting to lose my subjects, I jogged up to meet them, not a hard task since they weren’t moving too fast. I have to say, even though Brittany was a fit girl her broad ass sure had a lot of attractive bounce to it.
We kept walking past everyone, past the beach, and onto the street. I was wondering where we were going before we turned into a beach-adjacent bungalow. Judging from the pictures, this was Brittany’s home and like everywhere else I’ve been it was focused on comfort and ease. The pictures were of Brittany, at term in several different pregnancies, some bigger and some smaller, next to a chart of her measurements. As recently as last week Brittany measured an impressive 68 inches around her belly. It was obvious she had been doing this for years (she still looks under 25) and had been swollen up even bigger than what she is now with child. Britt helped Ali shimmy off the soaked shorts she had swum in and they stood back again to admire one another. This entailed a ton of belly rubbing and oohs and aah at the movement and kicks. Ali and I sat back onto a nearby couch and Brittany had to sit down on her favorite chair, saying being so big tired her out pretty quick. I saw through this, though and I think Ali did too. Once Brittany sat down the drops of moisture trailing down her thighs were obvious. Brittany was dripping wet and panting now as she sat back as far as she could. She saw the hunger in Ali’s eyes and scooted her hips up and spread her legs apart, her belly pushing towards us. Ali shuddered next to me and slid off the couch and slinked along until she was at Britt’s feet. Brittany’s pussy was bright red and already lubricating furiously, pooling under her and filling the air with musk. I was hard as a rock, my cock straining against my pants as I watched Ali massage the insides of Brittany’s legs before she started kissing the underside of her belly. Britt’s view of Ali was completely blocked by her own pregnancy, so she let her head fall to the side and she kept eye contact with me. She bit her lip and thrust forward with a bolt when Ali probed her pussy with her tongue, Ali obviously experienced at eating out another girl (especially a girl with a giant belly). Brittany eyed me up and down until her eyes rested at my obvious erection and she gripped her belly as Ali went to work trying to making her friend cum. Brittany hadn’t been kidding about how horny she was, this girl was pouring like a faucet now that Ali was lapping at her pussy like a melting ice cream cone. Finally the tension broke and Brittany reached out for me and I was next to her in a heartbeat, shirt already off and her clawing away my zipper and briefs until she pulled out my cock and stroked it with hunger before devouring it in her tight mouth. Any pretense I had about ethics and detachment was lost as this swollen model gave me the loudest, wettest blowjob I’ve ever experienced.
We must have been an erotic sight, Brittany swallowing me while a nude Ali had graduated to pushing her fingers into Brittany while tasting her juices. Britt was deep throating me now, her head bobbing up and down while I cupped her head in agreement. I think the only reason I held her head was to keep from applauding because she was so intensely focused on my dick it left my legs weak. I was amazed enough that she could take as much of me as she did. There is no doubt now that my penis has grown noticeably bigger during my stay, longer, fatter and veinier than I’d ever seen it. Brittany began moaning and pushing her swamped pussy onto Ali’s face as she began to cum. Ali redoubled her efforts, leading Brittany over the peaks of orgasm before leaning back on her heels to show her face showered with juice. It took only a moment before the sex-crazed Brittany was ready to go again, but now that her head was clearer she was a bit more demanding.
At her instructions, Ali laid down on the floor and Brittany kneeled down in front of her. They kissed softly as much as they could, their bellies preventing them from getting too close. Brittany had other plans in mind and slid herself down Ali’s body until she was parting her thighs and licking her way down her thighs until she was tonguing her tight pussy. She was slobbering all over Ali’s lower body, tracing up from her calves to her pussy to her belly button and back around again. Brittany’s belly was so huge it was pressing into the carpet, pulling her down so her back arched up and her ass stuck out. It was clear by now that Brittany was a cock-hungry slut, so I had no problems kneeling down behind her and sliding my dick into her bright red pussy, bottoming out on one stroke. Brittany felt me deep within her and used the excitement to shove her tongue deep inside Ali and claw at Ali’s round ass. A woman as pregnant and horny as Brittany demanded a good, hard fucking and I jackhammered into her sex as her and Ali built toward orgasm, Brittany shoving her head deep in Ali’s crotch as Ali began to cum. Ali shivered and shook with pleasure and I went to work making sure I wasn’t the only one not to leave satisfied. I grabbed a handful of brunette hair yanked back, arching Britt’s back even more and rewarding myself with a deep twinge around my cock. Brittany was humping back at me as best as she could given her belly, her tits slapping wildly against her bump. I looked down at Brittany’s fat ass bouncing against my legs and noticed for the first time a tattoo just above her ass cheeks, reading in curved ornate lettering “BORN TO BREED”. I went crazy seeing this, fucking this proudly knocked up slut with quick, deep thrusts until I couldn’t take anymore and came inside her. I must have shot over half a pint of cum, jizzing for near a minute until Brittany collapsed on her side next to Ali. They interlocked hands and rested for a while before deciding it was time to go about their day.
They each rose with a grunt and left to shower together. I know Ali grabbed a bottle of cocoa butter moisturizer as they waddled to the back so I imagine they are taking turns rubbing each other down. I don’t have long until they return. I think I feel my body chemistry changing even as write this, drawing me deeper into this rabbit hole of hedonism. Down and down it goes, where it ends I do not know. The most worrying part is that I don’t really want to know.
