The three of us smiled as we observed Barb cum again. Then it was over. As relatives and friends, we had taken a giant step over the line. We all knew it. It almost felt like a right-of-passage thing. I headed for the bathroom and Debbie followed soon after. After taking a piss I helped her clean up with a washcloth. "I never thought taking it in the ass could feel SO good! Thanks, Donny." "Hey it was my pleasure. Just let me know when you want it/me again." "I will," she said, and we laughed. We chatted for some time about what a wild evening we had and how Rudy and Barb's relationship might have changed. Since we hadn't heard a peep from the front room, we decided to spy on them. Sneaking into the kitchen, we could eavesdrop on their conversation.
