Sex Therapy for Too Much Excitement - I can't stand it no matter how many times I come!

"It's not even close."
Have sex with your girlfriend every day!
However, Jun is rejected because he is unemployed.
He decides to look for a job, but the results are not good....
Then he meets a beautiful doctor who scouts him out as a sex therapist!
It is a naughty job to solve your sexual problems by putting your body on the line....
She teaches pleasure to girls with insensitivity and patients who are aching because their husbands won't embrace them!
She uses her sexual prowess to make her patients cum and shoot many times every day!
She is a pleasure job, thrusting from front to back, from bottom to back.
Just when you think you've found your true calling, your ex-girlfriend comes to you as a patient...?
