What did Crystal forget?
She had fucktoy duty tonight with mom
"Well, you see..." Crystal said awkwardly. "I've forgotten my homework and books back at school..."
"And?" You raise an eyebrow seriously. Sometimes, it was hard to tell who the older sibling was, given how immature Crystal could be.
"And, it turns out, tonight, I've got fucktoy duty with mom tonight." Crystal explained. "Normally, I'd be happy to ditch my homework in favor of mom fucking my brains out, but Mrs. Ferguson will have my ass if I fail to complete another assignment."
"And who's fault is that?" You tell your sister seriously.
"Could you cover my fucktoy duty tonight?" Crystal requested. "Mom doesn't care who she fucks, as long as she's satisfied herself. C'mon!"
This was an easy 'no.' Crystal had to pay for her own actions; if she couldn't get her homework done, that was her fault, not yours.
"Come on, Doug!" Crystal pleaded. "I'll do your homework too!!"
This was a somewhat enticing offer.... "I don't know..." You said teasingly.
"Fine, I'll do your homework, AND your chores!" Crystal offered out of desperation as their mom, Lisa, walked through the door, completely naked, her massive cock erect, and a look of strong sexual desire.
"Ready to go, Crystal?" She asked lustfully. Crystal turned to you with an expression of legitimate desperation.
You hesitate on these words for a while, questioning whether or not to let Crystal off the hook so easily. Finally, you came to your conclusion:
What's next?
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. Still extremely attractive despite her age and how many children she's had
