Nico-chan, introduced to the beauty center by a friend and not really knowing what to expect, receives a brief explanation from a friendly-looking male staff member and is then given a beauty drink. The massage begins normally with her clothes on, but for some reason, she reacts involuntarily to just being touched. As the treatment progresses, Nico-chan becomes more and more aroused, even wanting to be touched in more naughty places. As if sensing this, her clothes are removed, then her underwear, leaving her naked. By then, her clitoris is rock hard! She is tormented relentlessly, and finally the staff member inserts his penis into her ass! Nico-chan hangs her head in exhaustion. But the real fun starts now! Before she knows it, she finds herself in a suspicious room, her hands and feet bound, and the merciless pleasure training begins! Oil is smeared all over her body, and she is tormented with electric massagers, anal beads, vibrators, and every kind of toy imaginable, and the ultimate climax is when an electric drill is inserted into her ass! Nico-chan was orgasming the whole time, and I think she looks even prettier than before it started!
