Dee said sorry that she had let things progress this far and if she hadn't left then she would have not been able to stop it, she was very excited. Junior was napping so we went to the bedroom and had very excited sex, after words Dee held me tight and was very somber. Later it the evening after Junior was asleep we talked about what had happened. We both like Dee's exhibitionism and her sharing intimacy with Matt but I am not sure if we really considered it going to the next level, sex. It excited me but also scared me. We made love again and slept on it.
The next evening we talked again and decided that we loved each other and with Matt it would only be sex without the same feeling she and I shared so if it happened it was ok. Dee still walked in the park and seen Matt but did not go back to his place since it was during the week with no one to watch Junior. On their walks they held hands and kiss the same as before but Dee told me she was a little stand off-ish towards Matt since she was still deciding her feelings.
Thursday evening of that week Ray stopped by for dinner and the game. I ask Dee if she could wear a pair of boy short underwear she had that had vertical stripe and waist strip so they look like cotton gym shorts , also pre-Junior so they fit very tight showing a lot. After some persuading she agreed as long as she could wear one of my tee shirts which covered some of the shorts. I also ask her not to be constantly pulling the tee down.
Nothing unusual about that night, dinner and the game with me in my chair and Ray on the couch watching Dee's every move, while Dee taking care of Junior and getting us beers and snacks. During the game I got my monthly how are you call from my parents. I went in the other room to not disturb Ray and Dee and had ended the call fairly quick so I could get back to the game. When I came around the corner I saw Ray and Dee wrestling around and joking. I decided to stay back in the shadows and watch. He told her she was being a brat and pulled her towards him and reached around and swatted her butt. She said that it hurt and stop before I heard. He said he was sorry and rubbed her butt where he had slapped it. She did not stop him until he had rubbed her for a minute or so and it was starting to become more gropes than rubs.
