Our Bodies, Entwining, Entwined Vol. 2 (Kodansha, 2021)

Misuzu and Mikage are two people who work together at the same office. They find themselves mutually attracted to one another and begin to date. They each have their own hang-ups when it comes to sex, but the two make a promise to each other that they're going to work hard to be able to have sex that is both mentally and physically gratifying. They decide to apply what they learned from having sex last time, when they stopped in a panic, and get it on. This time, they're deliberate, take their time, and teach each other about what feels good. During their tender time together, Misuzu starts to go through a change...? Two people who joined the company at the same time as Misuzu, Eiji and Anri, both don't appear to have ever had any concerns about sex, but it seems that they do...?
