As a fourteen year old girl I had a friend who's mother was something else. She'd divorced her husband and didn't care if anyone knew who she was fucking. But there was one thing she kept quiet about and it was one thing I discovered after having a sleep over at their home.
Nearing midnight I got up to go the bathroom, and heard noises coming from downstairs. Ever the enquisitive type, I snuck down and couldn't believe what I was seeing. Knelt up on the rug was my friends mum. She was naked and encouraging her, their family dog to mount her. The dog was an Alsation and believe me for a dog, it had a really large penis. After struggling for some time to get the dogs cock into her pussy, she finally managed it and boy did that dog begin to fuck her.
After what seemed like an age, the dog turned a little and bucked even harder up her pussy. I could then easily see from where I stood, my friends mum taking the cock deep up her pussy. And then totally bewildered after some time, I witnessed her cumming only seconds before the dog spewed lots of semen up her love hole.
I was about to move thinking it was all over, but moving the dog off her, she got a hold of it and had it put its paws on her chair. Getting below it she took hold of the dogs cock and began to suck on it, taking in the last of its sperm into her mouth. Licking her lips and swallowing the sperm, she got up and calmly walked into the kitchen with the dog following her.
I quickly took myself off to the bathroom, then as quietly as I could went back to sleep in my friends bed with her. About to fall asleep thinking of what I'd just seen, my friend asked where I'd been. I lied and said I had a funny stomach. My friend said "Oh" and promptly put her hand between my legs. I didn't move for some time, but my friends hand did, massaging my pussy through my knickers. I'm not going to say what we did the rest of the night, as that is probably for a different confession, but what I will add, is every now and then, my friend who I very much still keep in contact with, spend time together at a hotel close to the home I share with my husband.
It's our secret that we have kept since that strange night in her mother house.
