A student of a gal I met by chance came to our house. I never thought this would happen... The gal called out to me, and in no time my room was transformed into a hangout for gals. It's now a gal style, but she invites a man to the teacher's house and does whatever she wants! Even though they're men, they're all old guys. What kind of relationship do they have? Should I be angry as a teacher? But I also secretly enjoy these guys looking sexy.
