My aunt moved in with us after discovering her husband's visits to brothels and leaving home. I ended up teaching her about the sex industry. In the bathroom, she straddled me without penetration, but just before I could enter her, my stepmother caught us. That night, my aunt came to my room and we continued, finally having full intercourse. The next evening, I also ended up seducing my big-breasted stepmother. My father was away on a business trip. The aunt I'd always admired came to visit. She got along well with my stepmother, and they even bathed together one day. When I unexpectedly entered the bathroom, she offered to wash my body. Later that night, I went to my aunt's room and resumed intercourse, picking up where we'd left off in the bath.
