This series is an anthology. The following summary is for the first story. All chapters are listed under the same summary despite differences.

SpoilerYukino, who worked as a manager of a cosmetics store, had already achieved her career goal, but still felt empty when it came to her love life.

However, on her off day, she met a lost foreigner, and she ended up spending the day showing him around. She thought he was like a cute spoiled cat… until she was caught by his passionate gaze.

An ardent night of tender caresses and kisses in a hotel suite. They were two strangers, but their feelings were transmitted seamlessly.

From MangaHelpers:
Tonight, Natsuo loses his virginity. His partner? Her name is Rui and he just met her today after school. She's the one that brought up this whole situation, stating that she wanted to simply gain the knowledge about sex. She does not want to start a relationship, nor does she care about Natsuo.
Afterwards, Natsuo feels guilty for losing his virginity to a girl he doesn't even particularly like. Mostly, it makes him feel like he betrayed his crush to his high school teacher: Hina. A quirky love triangle story unfolds as Natsuo, Rui, and Hina all end up becoming part of the same family.

Yuzuki is a call girl - a sex worker who doesn’t make prostitution her main profession. She gets sent to another world, and in order to get back to her own world she has to collect orgasms from all the different fantasy races that exist in the world she was sent to.

So yeah. It’s similar to JK Haru is a Sex Worker in Another World, but compared to that the fanservice is more explicit and the story itself less dark.
