My Proud Little Sister Isn't Called "Benko" For Nothing

STORY
My tsundere sister Mai
begged me for sex, so I gave in.
It was something we did.

Eventually I got a girlfriend, but
Yuri was timid so we didn't have sex.
Me and my sister kept at it.
One day Mai dropped a bombshell on me.

"Your girl... I've had an orgy with her before."

What. The. F*ck?

Later, I learned another shocking thing.
Mai was known around her part-time job as
"the human toilet" (benko).

All this time my sister had been screwing me,
she'd been screwing hundreds of men.

"So what? I'm super f*ckable. Look,
look at my p*ssy oniichan!"

She continued,

"I'm sooooorry, what was I supposed to do?
It's easy money and maybe I like it.
Maybe I like being a cum sponge for guys."

I was furious.
And yet, was I getting turned on...?
