Camping with the family

I'm Jarrod 23 single oldest of 3 and in August went camping with the extended family. I'm not a woodman and took along some books to read and games to pass the time. While most of the others were hiking, fishing and boating I stayed close to the camp and read my books or played my games. My aunt Dianne 37 divorced (mom's younger sister) stayed behind also and kept busy sewing or cooking. While the rest of the families wandered far and wide, Dianne has 2 children 15 and 13 and they are both very active in sports and were involved in everything going on during the camping trip. After the family returned for lunch and then left to continue their activities I would go into the woods to a quiet clearing to read by myself. I would masturbate there as well and thought it was far enough away from anyone to catch me. I was wrong, Dianne had decided to go for a walk and came upon me masturbating. I was shocked and she just laughed saying don't worry I won't tell the others. I was still a bit shaken and she came closer and took hold of my still hard cock and started to stroke it. Then she went down on me and I couldn't hold back and she took my load into her mouth and swallowed it all. Then saying I owed her big time and told to get her off and I did as I was told. After I had managed to get her off as well, I was hard again and she told me to fuck her, under her directions I fucked her and she climaxes at the same time as I did and wrapping her legs around me held inside her as I blew my second load inside her. After which we parted and returned to camp from different directions, we had sex twice more on the camping trip. But I only came inside her the first time, since returning home I've seen her several times and had sex each time. Then last week she told me she was pregnant and as I was her only lover I was the father, she already had some tests done and so far everything is okay. Dianne has told everyone else now that she is pregnant and is going to keep the baby, not saying who the father was. I found out also last week that Katherine 41 my mother knows I'm the father, as Dianne and her are also lovers. She won't tell anyone else and last weekend, when my father and siblings were away, Katherine joined me in my bed and I fucked her and she made sure I was out before I came all over her belly. I'm their sex toy and I won't complain, as I'm enjoying the sex.
