Hello, I'm looking for a NSFW manga! Where a girl being tested by her boss with the company's new product (sex toys). I don't remember if it's an oneshot or sequel. Have been looking for it for awhile. Thank you!

Neither of them. The toy she used was a dildo. From what I remember at least one of the character had black hair and it all happened in an office. The art was really good.
