I'm a married man, 65 , retired. My wife and I own a German shepherd . When ever there is female in heat in the neighborhood, Rex loves to mount both our legs. This one weekend , my wife had gone to visit her Mom and Dad. It was a far drive , so she usually stayed over. There must have been a hornie female close by. I was watching a porn flick , and got aroused. I took all clothes off and laid on the bed , the movie on , of all things was Women and their dogs. I really got excited, holding my now very cock , starting to jerk myself, I called the dog. Instantly he was along side the bed. I pushed my cock over towards him, he sniffed and started to lick me. I spread my legs and patted the bed, for him to jump on the bed between my legs. I gave him a little head rub and told him he was a nice,dog. by this time I started oozing out precum . Right away he began licking my cock. I've wasn't circumsized I pulled the skin back , exposing my big red head. His tongue was rough and made the feeling even greater. I pumped a little while he kept licking, finally I felt about ready to shoot a load. I tried to hold back, because it felt so great, but, I just to cum and shot all over his snout , be pulled back , but then came back and finish licking me dry. Later the evening, I got hornie again. Stripped and called for Rex. He was on the bed in a minute. This time I started to play with his cock, to see his reaction. I went about fondling him , gently at first. Then I started to jack him off. He was rock hard , and a good 6 inches, not so big around though. He seemed to be really enjoying what I was doing to him. He even started to moan a little and move around a little. I leaned over him, with my hand still holding his cock , I sniffed his crotch area. There wasn't any smell to speak of. So I kissed the head, he to had some precum leaking out. The taste wasn't much different than my wifes pussy. Oily and a little salty. I pushed my mouth down on his shaft and stated to run my tounge around his stiff tool. In a few minutes he really got excited and started to pound my face. In no time at all shot a huge load and I ended up swallowing it all. I laid back , figuring he was through. But to my surprise , he came to me and started to lick my cock. I in turn gave him a large load. I slept naked that night, in the morning I walked out the kitchen to fix some coffee and toast. Still naked , Rex came up behind me and started to sniff ass. I spread my legs and pulled my cheeks apart, he started to run his tounge my but . I led him out to living room, there I got on all fours. He followed me and started to lick my anus again. I told him to climb on. He must have understood. He mounted me, he right away was humping, but couldn't enter. I reached back and guided his stiff rod in, once in there was no problem , he started to fuck me very hard and very fast, all at once he gave a huge thrust forward, all I felt was a brief shot of pain. To find out , he pushed his knot into me. He kept pumping and finally shot his load. We stayed locked together for sometime, gradually he eased out. Sure glad we were alone. It had to be a good 30 minutes. Now I ask my wife when her next visit to her parents is. Her reply, why ? so you can have sex with our dog. Dumbfounded , I just stood there. She said , what do you think happens around here, when I'm home alone for some time. We both laughed, saying we should try a threesome , next time there is a female dog in heat. Lifes good. Here Rex, here Rex, come to Daddy. Got something for you.
