Mary, now 17, has a boyfriend but she still feels that I have a lot to learn at 15. Now let me tell you about that river, it was behind our house and really not much more than a stream .As growing up mom and dad would take us there letting us swim. Well I certainly didn’t stop her from grabbing my cock , I helped her . When I started to do the same I stripped and she was quite surprised . Eventually Mary had grabbed Sam’s cock and was leading him away. It seemed that Sue was still liking my cock inside her but finally told me to get her out of the water. Mary made a nice breakfast as usual and told me that our mother called and they won’t be home again tonight. She then chuckled when I told her no,she gave me another kiss and said “I guess we won’t tell her then ”.
