Back in the day she was a legendary badass biker chick.

Her name is Ayaka.

As a street fighter she could beat anyone, full of righteousness and somehow pure.
Every guy fell in love with her. "Someday I'll make you my woman," they all promised.
Ayaka teased back, "The day a man can beat me, I'll be his woman."

Then she met Toshi.

A young man with weak fighting skills who, for the first time, won Ayaka's heart.
Several years later, they were married and happy.
It was a happiness Ayaka wouldn't trade for anything.

She'd long forgotten about her biker gang. But then... they came calling.

"I told you someday I'd make you mine," said the leader of the gang, Tatsuya.
Ayaka was brought to her knees by a flurry of more cocks than she'd ever dealt with before!!

...

She was a badass fighter, but even the very best has to lose...!!!
Witness the mesu bitchification of hot acme wife Ayaka!
