By the time we had got to the first floorlanding, Eileen was waiting for us by her front door. She smiled warmlyand invited us in. This really was a b...autiful flat with the best ofeverything inside.I presented Eileen with a bottle of red wine we had brought with us awelcoming gift. Eileen thanked us and gave me a peck on the cheek."Dinner is nearly ready," Eileen said as she showed us into the lounge.Drinks were offered and I chose a soft drink as I always did. That wasone thing that had not. .. masturbated to my own sister,” Bill replied.Wendy gave him a hug and kiss right in front of me.“Don't be embarrassed Bill, we love each other. I caught him once and he told me how he felt about me. Then I guess the feelings grew for both of us and we started having sex,” Wendy said.I was just stunned, I mean I had a small crush on my brother, but they were actually having sex.“Jennifer, seriously you look like you just saw a ghost,” Wendy said.“Well, maybe something like that,” I. Mom and Kay continued their conversation as well.I sat there listening to their conversations as they spent the next twenty or so minutes just getting better acquainted with each other.JJ was still sitting on the floor playing with his dump-truck quietly, while we all just sat there talking.Jon, Kay, and JJ then all got up to leave, but not before thanking my folks again, telling both mom and dad that I was the best babysitter they’d ever hired adding that they really appreciated being allowed. Teenage years were similar to dog years so that was almost forever.Cindy and Suzanne were something else that I needed to figure out. I was embarrassed that I had expected a hot threesome last night. One of the things Greg drilled into me was that you should not expect sex. If it was offered, treat it like a gift. Sex was a two-way street, or three-way in last night's case. Be prepared, but don't force the issue. There was a lesson in there, but that was too much for me to think about right.
