this is a true story from years ago, i was asked to care for my friends dobie while she was out of town. i had key to back gate the dog had doggy door so he could come and go when he wanted. he was a very nice dog loved to go for walks or ride with his head out the window. i would go over in the am and again in the evening. about the forth day i went over in the evening went thru the back gate then in the sliding door and no dog came to meet me strange i thought so down the hall i went to see what is wrong. shocked at what i found lady friend on all fours nude dog on her back banging her for all he was worth . ..just stood there watching then he knotted her and stopped humping ,thats when she turn her head and saw me the look on her face was total shock to say the least. my friend had come home early and didnt call me to let me know . well after the knot relaxed and slide out we had a long talk about her and the dog .she told me he was her second dog to fuck her since the first died and she got this one.and has been having sex with him for about three years now. she says it the best sex she has ever had nine inches plus the knot and no strings. we have been friends for years and have fucked a few times, so i got sloppy seconds that day and it was great pussy .and we had many more days like that . she took me to a fuck party four other ladies and their dogs, i got to watch some hot fucking and i got to fuck two other gals that day will never forget that. one lady had a great dane longest cock i have ever seen and she took it all plus the knot, she says the tip reaches her cervix and in a little bit i asked her to fuck and she was tight it was wonderful hope to go back again.
