Well, some random ideas off the top of my head, largely gravitating more towards the vignettes approach... 1) Shampoo dreams of life after she finally marries Ranma; barefoot, hugely pregnant, and already dreaming of her next litter. 2) In a timeline where the engagement switch went VERY differently, a pregnant Nabiki Saotome enjoys the loving ministrations of her husband Ranma... and her pregnant wife Shampoo... 3) A pregnant Ukyo's day at school, secretly reveling in all the attention as she gets to rub both her triumph and her womanhood in the faces of all who dismissed her. 4) In the privacy of their bedroom, a pregnant Kodachi puts on an erotic dance for her husband Ranma as a prelude to lovemaking. 5) Nabiki poses for a pregnancy photo diary, her attempts to deny she's totally into being pregnant growing increasingly feebler as she gets increasingly bigger. 6) Pregnant co-wives Shampoo and Ukyo enjoy some time together in the bath, confessions about their respective enjoyment of their condition combined with hormones leading to a bout of lovemaking. 7) After a magical macguffin gone horribly wrong leaves Ranma's entire "harem" pregnant, Ranma tries to keep up with looking after six pregnant women whilst keeping his raging pregnancy fetish hidden from them. Hilarity ensues. 8) Ranma reflects on how, really, Akane getting splashed with Jusenkyo water from the Spring of Drowned Bimbo Broodmare was the best thing to ever happen to him. 9) Kasumi muses about what a wise decision she made to marry Ranma. Who knew being pregnant would make her this horny? 10) Pink & Link wonder if maybe they overdid it with the libido-boosting medicine. Still, getting pregnant by Shampoo's husband definitely let them claim victory over their old enemy - and it means she can't kill them in revenge. But these bellies feel a lot bigger than just twins... 11) Ranma finds himself as the only one who can help Hinako out after a magical macguffin leaves the age-shifting teacher pregnant. 12) Natsume Saotome visits her husband Ranma's mistresses; it's best for them all to be friends, especially since they're all so very pregnant, after all. 13) Shampoo, Ling-Ling, and Lung-Lung. Three Chinese Amazon wives of Ranma Saotome. Three mothers-to-be of Ranma Saotome's children. Ranma has to admit, keeping it in the family actually seemed to work out for him in this case. ...And while I don't personally get the appeal, I suppose it's only fair... A) Ranma finally gets Cologne to agree to "divorce" him from Shampoo. Then learns the hard way that the price for doing so is he'll have to go through a magically accelerated pregnancy and give birth to a veritable litter of Shampoo's daughters. B) Ranma-chan tries to make herself comfortable after magical shenanigans from Happosai left her pregnant with the babified versions of Akane, Shampoo, Ukyo and Kodachi. Being pregnant with quads isn't easy, but it's worse when they actively wrestle inside her. C) As an enormously pregnant Ranma-chan goes into labor, Kasumi, Nabiki, Kodachi, Shampo and Ukyo try to figure out which of them is the father, courtesy of indulging in Ranma's futanari fetish via Instant Nanniichuan. Turns out the answer is "all of them". Finally, some just plain odd ideas... Alpha) Akane blows off some steam (who knew being locked in Spring of Drowned Futa curse-form would make her so horny?) by having sex with her lover, the very pregnant and very female ex-Ryoga Hibiki, now Akane's wife Yoiko Tendo. Beta) Akane's quest for bigger breasts goes horribly wrong when she accidentally ends up impregnating her breasts with Shampoo's daughters. At least Ranma can't laugh at her; his balls are in the same boat. Delta) Ranma's three heavily pregnant Chinese Amazon wives shower him with affection. In the backs of their minds, what's left of Ryoga and Mousse scream at the cruelty of fate. Epsilon) Eight months after taking her revenge, Shampoo basks in satisfaction at her achievement, having impregnated all three Tendo daughters, her rivals Ukyo and Kodachi, Ranma's rivals Tatewaki, Ryoga and Mousse, and even Ranma himself. It serves them all right for cheating her of her rightful husband. Gamma) Shampoo enjoys some lovemaking with her pregnant wife Gel, formerly known as Mousse.
