YRMN-018 You won't know the goodness of a mature woman until you've raped her

I ended up living in a popular room-sharing dormitory where the dorm mother is always present. When my senior smirked and said, 'Lucky you,' I had no idea what he was talking about. However, the dorm mother, Matsushita-san, kindly welcomed me, and as I was about to return to my room after greeting her, a resident came home and said to Matsushita-san, 'Can I ask for this here?' The dorm mother replied in a slightly sweet voice, 'Before dinner?' and then buried her face in the sweaty crotch and started sucking. I couldn't comprehend what was happening and stood there stunned.
