She started rubbing down my chest and sliding herself down on my cock not knowing that Mary just came on me. When I asked her why she was, she said that she was getting Sam ,( Sue’s brother) all to herself today. Mary convinced her to stay a bit longer telling her she had already called her brother . She then told me not to mention that you watched me giving him a blowjob ,that wasn’t him. The walk to the river was easy and having Sue helping to bring the drinks helped . I have to say licking and eating a pussy was almost better that fucking her.With her hands moving my head around between her legs telling me that she was going to cum ,makes me suck her longer. As I helped Sue out of the water I saw that my sister was looking out for her brother as always. She seemed to be joining my larger cock and after a while she climbed up on me .
