She was shaking while I continued licking and fingering her trying to get more of her tasty cum. “Oh you’re doing it” she said “ you’re making me cum ,better than anybody has ever done”. Mary then put her arm around me leading me into the house. Since my mom and dad were away for a couple days Mary made the decision to show me how much fun sex could be. When she saw me peeping in on her giving someone a blow job she understood why. Inside she turned to me and began kissing me with her hands holding me tight . I was still surprised that mom would let us play like this”. As we kissed I realized that my sister was a lot better than Sue, . With a smile on her face she said “if I knew you could be this good I wouldn’t have had Sue come to do this at all”.
