I had a hot date with a horny guy and the outdoors at a swimming lake. We sunbathed naked and were about to make horny messes. We didn't care that we had a lot of breeders! Suddenly my s***r stood in front of us and asked me what I was doing! Totally embarrassed, I admitted that I was cheating and that she shouldn't tell Papi anything. Then she said very boldly that she wanted something for it and she looked at the big cock of my date. I then offered her that she could have fun with him if she didn't tell my husband, her p**i, anything. Well, my s***r couldn't be told twice. First she blew his cock deeply until it was hard. Then she let him fuck her doggy style in front of everyone. Until he sprayed his sperm into her mouth and she greedily swallowed everything! Then she left us and said that she didn't tell anything!
