I soon had Wanda moaning and then I felt Debbie's mouth pull off of me and then her pussy sliding down my shaft as she mounted me and began to pump up...and down, her hands on her niece's tight chest as she did. It was like a synchronization, as all three of us orgasmed almost together. We lay together, panting, as we built our strength back up, Wanda was the first to stir, slipping my cock in her mouth as she slowly took more and more, until my balls touched her lips.Debbie went next, pushing. It was all white, mesh looking silky thin wrapping her totally nude body. I swear, I could see her pussy lips rub against each other as she walked to her bed totally oblivious of my presence with her in the room.I simply could not endure this and quickly moved to the bathroom for peeing, brushing and changing into my sleeping dress. I felt very proud as I was all done and looked in the mirror for the last time standing in my designer CK underwear, made specially to show the man bulge more. I was wearing a black sweater. He asked me to be comfortable. So I removed the sweater and handed it over to him. He took me around the house and showed me the house. When he went to get the 3rd drink for me, I was standing near his window and looking out. He came from behind and kissed me neck. Something happened in my whole body and just not myself. I just shook myself and stared at him.The signal was a No and a Yes. He seized the opportunity and played some music and asked me to dance. It. Then I thought to myself, "I wonder what it would be like to let another dog mate with me. Because the only dog I've ever mated with is Jasper. I'm curious, is it any different with another breed dog, I wonder if their penises all look the same. Even though it's gross, maybe I should do it. This might be my only chance to find out. No one is home except my son, and he's not going to come out of his room. Nor is my grandfather, so this is the perfect opportunity to do it. Because I don't know.
