This side of the lake was accessible for the most part by boat only as there were no nearby roads. We had left the marina about ten miles behind us wh...en I found the coves entrance.I had been back in this cove before but the other three gazed in fascination. They gazed up at the two rocky cliffs, which I estimated were nearly twenty feet tall, which towered on either side of the cove's watery entrance. Slowly I drove between them into a larger open area and then turned right going through. Before I can react, he pushes his way through the door and walks into the lit up room and sees Jazy laying in the bed.“God damnit!” He shouts waking her up.As she wakes she sees her brother standing at the foot of the bed. In a startled frenzy she makes sure she is completely covered up.“What are you doing here Jason?” she asks softly.“When I didn't hear from either of you I got kinda worried so I came here, I wish I hadn't,” he says angrily.After I had gotten the door closed, I came into the. Always had been.Then I had another thought. What if it’s a woman? Then I realized that I hadn’t heard anything that led me to believe there was anyone else in the house. I got a sense that I was wrong. Something didn’t make sense.I took a deep breath and reached for the door handle. Whatever was going on, I was about to find out. I opened the door and found Helen. She was sitting up against the headboard, naked, and holding onto a trunk of flesh so large, she actually had the glans in her. “Big bro I’m gonna cum” She warned me and a second later she was cumming hard her hands grabbing my head as she bucked her hips up grinding her pussy into my mouth squirting creamy liquid out of her pussy. God this was so sexy seeing her cum like that I got so horny I wanted to fuck her right there. As her orgasm subsided, I climbed on top of her and without really asking for permission, I grabbed my hard dick and guided it into her pussy. The feeling as my dick was sliding into her pussy was.
