Toni, that's a couple of years younger than me, and she is also my biological sister with 4 children of our husband. Then there's Kathy that is a good...bit younger than us, she's 23 years old with 1 child to our husband. "The Neighbor's Dog"It was the first weekend of last December 2017, Saturday, if I remember correctly. My sister wives Toni and Kathy, along with my daughter Skyler, and the other kids were off visiting Kathy's parents.. I was surprised to see her character. From that day I got interested to see her naked. I and my sis sleep in same room. One night she came with towel wrapped around her body; my dick raised and she changed into her night dress. Top t-shirt and lower pant.I got tempted and waited till everyone in home to sleep. Then I got courage and kept a hand on her waist. Suddenly I felt electrified. Then I moved my hands to boobs and waited for her reaction. No response from her side so I planted a kiss on. It was only momentary because Sampson the German Shepherd was smart enough to not compete with human males in matters of carnal desire.Female canine bitches were a different story.Sampson remembered a dog-fight with a pit-bull that made him teach the bitch-crazed animal that sometimes technique is better than a hard bite and no ability to use every dirty trick in the book to defeat one’s opponent. He had left that pit-bull minus some parts and a lot more educated about studying his enemy before. She sat me down in the chair and knelt between my knees. She then took hold of my cock and smelt it “ah ha …. I can smell sex” and then opened her mouth and started giving me a hard blow job forcing her head backwards and forward. I looked up and wow…..There was Rosa – spread-eagled being carried high by all the men. One to each arm and leg and one each side holding her up. Some of the women had gone ahead and were preparing some cushions on the platform while the others were following.
