What's next?
Sarah agrees, and Doug's horizons expand
"H-how do I get bigger?"
"Just to be clear, you'll let us fuck your brother if we tell you?"
"Yes."
Jessica, the girl with the 3-foot dick, grabs Doug's leash away from your sister and starts explaining. "What you have to do is take a boy, like this one here," she tugs on the leash for emphasis, "and keep him full up with cum for a week or so. Then you suck his boycum."
Sarah gives Jessica a doubtful look.
Another girl, Anna, pipes up, "No, it's true! My big sister says there's something in girls' cum that makes cocks grow, but since boys can't grow real cocks, it just builds up in their little balls."
Jessica starts talking again as she lines up her three-footer to Doug's asshole, "So we're doing you a favor by starting him off for you."
"No need to thank us," Anna added, as she **** her smaller two-footer into Doug's mouth.
As Jessica and Anna started thrusting in unison, violating both of Doug's ends at once, Jessica added, "Of course, we need to get some plugs and a chastity cage, so we don't waste anything.
After Jessica and Anna finish, Doug finds himself fuller than he's ever been before, but rather than finding relief after they pull out, he finds himself invaded again by another pair of cocks. The process repeats again and again until Doug is on the final two girls. Just as they are almost done, Jessica comes back from a trip to the supply cabinet, with a ballgag, a buttplug, and a selection of chastity cages. As the two girls finish and pull out, Doug's holes are plugged up.
Jessica then holds up a few of the cages to his crotch for comparison and selects the smallest one. "Looks like your brother here takes the extra small." Locking it shut, she adds, "Hmm... a little loose, but I think it'll be fine."
Anna pipes up, "That's good, Sarah. My sister says the smallest boys work the best."
Finally free of the girls, Doug tries to move, but finds the best he can do is wobble back and forth. His cum-filled belly is so bloated that he can't even crawl, and the weight is far too much for him to stand up.

Futanari World
You are a teenage boy who happens to live in a world where every girl is a futanari.
Futanari World is an alternate reality where every female is a futanari. this means that every girl has a dick, balls, and a vagina. This world is almost the same as ours except for the fact that girls have cocks bigger than guys. The average size of a dick-girl's dicks being 10 to 15 inches erect, this means that both sexes have more testosterone making them more horny and therefor making sex a less taboo. Sex is advertised more in the media, pg-13 now allows sex and nudity, and girl's bulges are more visible due to their massive sizes Doug (you) is a 19 year old boy who goes to high school and lives with his mom and two sisters, his dad died shortly after his younger sister was born, he loves his family in a platonic way only and has never had sex before. Blonde hair, thin, under average height, 6 inch dick erect. Crystal (older sister) she is 20 years old, almost 21 and is going to college. She comes home from college often, and is usually nice to her brother, whom she loves. Red hair, c-cups, average weight, taller than Doug, 12 in. dick erect. Sarah (younger sister) she is 18 years old and is a junior in high school, making jerking off her favorite activity. She loves spending time with her brother and often forgets her issues of Playgirl in his room. Blonde hair, thin, b-cups, 10 in. dick erect. Lisa (mom) she is 40 years old, often at work as a lawyer but when home likes to spend time with her family who she loves. Red Hair, d-cups, 14 inch dick erect.
