A family of 4 women? That has got to be a story worth hearing, so you head over to visit them.

You are welcomed at the door by Lena, a pleasant brunette who, while hardly flat, is not overendowed. She is quite friendly and you think she might be willing to be a meal if asked the right way. Her welcome is sincere, as is her warning that the kids were not food.
[Her desire to protect the kids from being devoured would seem more reasonable if you were not watching 2 little girls playing with a trampoline. One jumps off and then the other climbs on and then jumps off too. The purpose of the game becomes apparent when one girl gets under the other girl as she jumps down and opens her mouth extra wide as the jumper sails into it. The 2 end up on the ground with the jumper protesting it was unfair. It was only one leg, not two. But the other girl continues to devour her, and with a sniff, the jumper accepts her fate.
Once she has finished eating her companion, the winning lass, and her huge belly, stagger in to tell Lena she is going to take a nap, a situation Lena treats as routine.]

Lena explains that raising children is always a hard task, and raising them in a vore environment is even harder. You really want both parents, but if the boy is not available for some reason, you make do with what you can get. In their case, they are 4 different women who got knocked up 4 different ways, and banded together to raise their kids.
She doesn't say how they got with child, but she looks like she will say if you ask.
