Even tonight they went out and told Mary they would be gone for a couple days. She then chuckled when I told her no,she gave me another kiss and said “I guess we won’t tell her then ”. Eventually Mary had grabbed Sam’s cock and was leading him away. When I was helping Mary get the food for the day at the river she seemed pretty happy. It seems like Sue likes to suck cock too, she told me Sam would only let her suck him after he fucked her. Just as I was starting to cum I looked up seeing that Mary and Sam had sat down watching us. My sister and her girlfriends wanted more
My sister Mary looked after me since the day I was born and continued to feel she needed to this day. “This is going to be fun,” she said, telling me she has only had sex outdoors with Sam . I was woken up by Mary in the morning feeling her sucking my cock ,Sue was still asleep.
