I have many gay friends so it's cool" So when we got to the car park and I unlocked my car and we both got in. McKenzie turned to me and said "Why hav...n't we started driving yet?" I turned to face him in the passenger seat and said "We are just waiting for Lizzy" When Lizzy got in my car she said "Hey babe. Hey McKenzie you getting a lift home?" McKenzie said "yeah I hope you don't mind?" Lizyy laughted and said "Not all all" So I drove Mckenzie home and when he got out I pulled my window down. As he felt and tasted her warm sweet tongue enter his mouth a hundred conflicting emotions ran through his mind. "If this is wrong why am I so excited?" he asked himself.Now Ken was well versed in kissing and this was the best kiss he had ever received. That still didn't stop the nagging conflict within his mind."This is your sister," he told himself as she wrapped her slender arms around him.Now between his silky clothing and hers and her long lingering kiss he had gotten very hard, but still. I bit my tongue and my body shook like a leaf in a wind storm while he pumped his hot doggie sperm into me. It was all I could do to keep from crying out while another orgasm ravaged through me.We stayed knotted together for over fifteen minutes while he continued to pump his seed into me without moving his body. The dog was quite happy and he resumed licking my back and panting while I had an almost continuous orgasm as I felt little jets of doggy cum hitting my cervix.He dropped his head down. Whatever she said, he was going to turn it into a reason to break up. Jacinda summoned up the courage to ask the necessary questions. “Well, I was wondering,” she said in her sweetest voice possible, “I have been thinking about all the women in your past. And I’ve tried to make sense of the patterns in your life. Do you think the reason why you are so uncomfortable with being naked around me, and the reason why you seem to enjoy more of a wham, bam thank you ma’am is, I was thinking maybe.
