I grabbed a beer and popped the first one in the machine. The screen went blue then it lit up with our den , the camera had been set up facing the cou...h. This is strange I thought then all of a sudden a man's hard cock came in from the right and when he moved to set down I saw it was Tim. My wife had just recently started fucking him or so I thought, but apparently this video was several years old. Just as I thought Andrea came on the screen next, she was completely naked and judging from her. "She doesn't look like much." "No, but she made that horse of hers happy", Mark said.This shocked Katie since she thought Mark was keeping her secret, not telling people. "Well, let's see how she does in the harness", the owner said and led them into a structure Katie had only seen, never been inside. But she knew what it was for; breeding mares.Inside was a contraption that looked like it was for keeping a mare in place while a stallion bred her. "Strip down and get in the harness", the man. It was not going in completely. He kept trying and trying, I was experiencing a lot of pain and crying. Seeing that, they put a small ball-type thing in my mouth which did not allow me to shreak.After about 10 minutes, he managed to push his dick inside my ass and started ramming it. I was feeling like I was fucked by a train and initially, it was causing a lot of pain.But soon, the pain turned into pleasure and I started to enjoy it. My shreak lowered and instead of opposing, I started. "Incest is one thing, but incest with your sister when her husband is in the house is something else again and I backed away from her."Oh no you don't" she said as she turned and came after me, "I'm not passing up a chance to get fucked while he is only a few feet away. Just the thought of it is making my pussy drip."She grabbed me and pulled down my pants and went to her knees in front of me. Once she had her mouth on me it was over — I surrendered. I gave in, but I was nervous as hell and I.
