リラクゼーション癒香･Ｍ ～マッサージからマゾへの快楽調教 サキ女王様編～

You, the protagonist, had been feeling a little stressed lately, so you decided to treat yourself to a massage—nothing out of the ordinary, just a casual way to unwind.
The therapist assigned to you, Saki, noticed your reactions during the session and picked up on something: you had the makings of an M-sub.
As the massage went on, she started teasing you, testing the waters.
When it was over, she handed you a business card.

"Sir, if you’re interested… I can do something even more exciting for you."
