The plants are sterile. Your womb is needed.

You just finish packing when your father comes into your room. It has been ages since you were in this cabin, and half the clothes you brought on the trip had never been worn. Even now, it fels weird being clothed again. Your ass distorts a sundress that once fit properly, the bottom of its curves just visible below the hem. If you bend over, as you are doing now to pick up one last item, you're indecent.

Your father comes up behind you and wraps his arms around you. The bulge of his cock presses the fabric of your dress into the crack of your ass. "What do you think you're doing?"

"Packing, duh. Aren't we leaving tomorrow?"

"I am. You aren't, though."

You frown and pull away from him. Turning around, you say, "What do you mean?"

Your father explains. Turns out that the plants you and Christina birthed cannot reproduce on their own, nor can Rayna and Carrie properly pollinate them. They are every bit as productive as the company had hoped, but there is only two of them. For the aphrodisiac to scale, they needed vast greenhouses of the things.

That's where you and Christina come in. Your bodies have proved receptive to pollination.

"So you want me to stay here forever and just pop out new plantlings for you? Ew. No fucking way."

"I'm not giving you a choice, Ally. You've spent nineteen years mooching off my money and growing into a more selfish bitch than your mom. These past two weeks have been the best I've ever known you: on your back, legs spread, begging to get fucked." Your father's eyes sparkle with undisguised lust. His hands now grip you around your wrists, and you know there is no point in struggling. Even if you managed to get away, there is no way off the island except a boat hired by your father.

Your father escorts you to the lab. Christina is already there, nude and in the middle of mating with Rayna. At a harsh order, you disrobe and approach Carrie. The plant woman rouses herself from slumber and comes alive at your touch. The experience is every bit as electric as last time. If anything, now that you know what to expect, you can relax and let it happen. Carrie seems more eager and energetic than last time. You wonder if she recognizes that you have been pollinated before, if she's excited because she knows this mating has a good chance of working.

Afterwards, you and Christina end up back in a featureless room with a large double bed. The two of you hold each other. If it weren't for the feeling of warmth spreading through your body, emanating from your womb, you'd be on the verge of tears. How dare your father do this to you?

Michael arrives soon. "I thought you might need a dose of cum," he says. Without further ado, he removes his pants and underwear and sits on the bed.

There's **** now but to submit. For better or for worse, you've been pollinated again. Already your loins burn with a need to get fucked. So both of you climb onto either side of him. Christina pushes him down into the sheets and starts kissing him while you pay attention to his cock. You take the head in your mouth, your lips closing just below where it meets the shaft. You tease it with your tongue, then you start to bob up and down along the length of the cock. Already semi-erect, the member swells to its full, rigid proportions inside your mouth. You can taste his sweat and his pre-cum.

Letting the cock slip out of your mouth, you migrate towards his balls. Michael grabs Christina's ass and manoeuvres her in line with his body, her pussy poised to impale itself on his penis. As you continue to kiss and lick his scrotum, you take Michael's cock in one hand and guide it inside Christina's waiting pussy. You're treated to an exquisite view of her firm ass bouncing up and down his cock, which now glistens with a mixture of pre-cum, saliva, and pussy juices.

Christina comes and then abandons ship. You crawl up along Michael's body to take his place, briefly enveloping his cock in your cushy tits. You rub them up and down the length of him. Ever since giving birth, you've been so much more sensitive in this area, and the feel of his cock in your cleavage brings you closer to coming than you would have thought.

But Michael is having none of such foreplay. He pulls you up by your shoulders, then flips you onto your back and rolls you over. Soon enough he's inside you, fucking you missionary. Christina crawls around to the head of the bed and offers you a nipple. It's too early for her to be making nectar yet, sadly, but you still give her the pleasure of sucking on the hard and sensitive bud at the tip of her tit.

"Fuck, I'm going to cum!" Michael announces. He pulls out of you. "Roll over and show me that nice ass. Christina, get down next to her."

You obey, getting on your hands and knees and sticking your ass in the air. Christina joins you. The two of you are now side-by-side, facing away from Michael. He resumes fucking you. In no time his cock starts to twitch and throb, and you feel his cum flood you. After a few seconds, he pulls out and penetrates Christina as quickly as possible, maximizing the amount of cum that enters each of you.

Thus bred, Michael pulls out and allows the two of you to clean him off. His hands caress your heads; you can feel the heat of Christina's face next to yours as you take turns licking and sucking his cock. "You two are such hot sluts. I'm glad your father decided to keep you here permanently. I used to think working here was a drag, a dead-end move, but now I'm going to love fucking you day-in and day-out."

After you're finished, he gets dressed and leaves. The door clicks with finality as it closes behind him, and a red light comes on. You're locked in.
