I had been having a relationship with my son for some time, but that wasn't enough and I ended up having a relationship with my best friend Ryoko's son. I later found out that Ryoko was having the same thing, and before I knew it, she was having a relationship with my son too. What's more, Ryoko and I weren't just best friends, we were in a lesbian relationship. One day, our sons found out about it. And so the four of us ended up in a forbidden mother-son swap.
