With each violent stroke of the mans sword of flesh, her thighs cut into the edge of the wooden table. She was going to have bruises across her thighs...later, she knew it but she didnt care. The crude nasty scene she was performing in drove her crazy, she had not for one minute thought anything like this would happen when she had let Arnie talk her into it. They had always experimented throughout their marriage swapped couples a few times, invited a few strangers to their bed. Nothing they had. The current in the Deben flows at up to almost five knots, as fast or faster than a small dinghy can sail, and having launched, the sailor has to negotiate an obstacle course of dozens of moored boats in every size and sort."Amy," I explained, "it's going to be a bit hectic at first.

She continued looking at me as she bit her lip and began to writhe her hips and flex her muscular asshole around my dick. Over and over she squeezed me with her ass, as if she was trying to milk the cum from my balls with her ass alone. "Oh my God!" I moaned. "Does that feel good?" she asked. "Fuck yes!".
