MIDE-926 Today, my big-breasted girlfriend who I gave a ride home is playing hooky… Hope Ishihara

She and I, along with our senior colleague, were on the same shift. One day, only my schedule changed to a different day. Since we usually worked until late at night, we would always go home together, but now our senior colleague drives her home. It makes me feel uneasy, but she is serious and devoted, so I'm sure everything's fine! But since then, when I call her, there's no response, and she's also been skipping work without notice… I'm worried. Just in case, I tried calling our senior colleague too, but it didn't go through… Surely, nothing happened between the two of them, right?
