MIDE-926 My big-breasted girlfriend, who was given a ride by my senpai, is absent from work today without permission... - Nozomi Ishihara

My best friend, my girlfriend, and my senior worked on the same shift, and one day I changed shifts to a different day of the week.I worked part-time until midnight, so we always went home together, but now my senior has to drive me home. - I feel a little nervous, but she's serious and dedicated, so it's okay! - But then I called her, but I couldn't hear from her, and she was absent from her part-time job without permission...I'm worried, but I wonder if she's okay. - Just to be sure, I tried calling my senior, but he couldn't get through... I never expected to be alone with a senior like that, right?
