Shizuka was a new graduate who was assigned to the hospital this year. I was treating her as a trainer, but before I knew it, we became sex friends. We usually had sex at home or in a hotel, but seeing each other every day made me want to do it, so I ended up doing it at the hospital too... She gave me a blowjob in the bathroom, made me drink my semen, and inserted my dirty dick raw and came inside her for the second time. Later, we were alone during the night shift, so I inserted it raw at the nurse's station and came inside her. She asked me to do it again, so we went for the second round on the sofa in the waiting room and came on her face. On another day, we had sex at a hotel after work and made her cum many times. She's the best sex friend because she's good at giving blowjobs and we have good sex chemistry.
