Uhh. Something-something vampire venom that makes the uterus fill up with so much blood that their victims end up looking pregnant, weakened and struggling to get away with their cramping womb sloshing painfully in their engorged belly, and making them easy prey for the vampires to capture. These bulging bellies are satisfying but very painful to bite, so more merciful vampires will simply eat out their victims, lapping up as much blood as they can before making them cum repeatedly to ease the cervix and release more.
These blood bags can be used as a primary source of sustenance, but most vampires only use them for entertainment or light feeding, as high volumes of blood must be drained with careful regularity or else they become too thick. If an overproducing womb is neglected for even a few hours too long, it can trigger a period so severe that it’s more like labor, where the victim must endure days of excruciating cramps as their womb voids uterine lining. Of course, some vampires consider this menstrual buildup to be a delicacy, and think of feasting on it and watching their blood bag suffer as “dinner and a show.”
In times past, vampires of great status would keep court with dozens of beautiful blood-pregnant maidens, dressed in form-fitting gowns to show their prosperous bellies, or even kept in nothing but fine jewelry to show off the bites and bruises on their grotesque guts. In modern times, such practices are frowned upon, and those who enjoy the extravagance of such a harem must be more discreet. Many a poor young woman has found herself chained up in a dungeon full of groaning and frighteningly bloated bellies, and spent the rest of her days being eaten out and having her huge aching belly bitten by gaggles of partying vampires who barely see her as a person.
Even those who consent to having their wombs turned into blood bags often regret it, as even if the vampire is amiable and lets them end the association on their own terms, they’ll realize their body is irrevocably changed and that their menstrual cycle will now include growing to the size of a full-term pregnancy in just a few weeks, then needing a few weeks more to bleed all of it out. Most such people end up returning to the service of vampires, as their new medical condition makes holding down any other job very difficult, and they can at least derive some pleasure from the situation. 🩸
