Serina is a sharp, career-oriented office lady.
She's usually strong-willed and tough with her subordinates, but suddenly the tables are turned.
Her actions angered a client, resulting in damage to the company.
To make her take responsibility, the client and her colleagues decide to punish her.
As she is teased with caresses - choking, breast massage, butt massage, and butt spanking - the pleasure and humiliation make her masochistic.
"Oshima-san, you join in too, if you want to continue doing business with us."
Her boss joins in along with the corrupt president of the client company, and the three of them continue to torture her with a vibrator, a dildo, and a massager.
Her subordinate rips her stockings to shreds and begins licking her feet.
She uses a vibrator on top of her panties, then slides them down and uses a vibrator and fingering to simulate a squirting orgasm.
From there, she is made to understand what is going on and moves into an intense foursome.
With each orgasm, Serena sinks deeper into the swamp of masochism.
Confused and crying between the frustration of being forced to orgasm and being creampied,
and the pleasure of still cumming so much, Serena is transferred to the company of an unscrupulous president,
as the company's exclusive orgasmic maid secretary...
