My sister and I lived with our dad after our parents split up because my mom had cheated on him. We lived on about 3 acres on the outskirts of town, and my dad was a big time hunter and had 3 hunting dogs. 2 Beagles and a chocolate lab. The lab was not fixed and he would breed him from time to time for stud fees. This was something he had done for years, even with prior dogs.
We would get home from school around 3:30 and he wouldn’t get home until about 6:00 usually. We had both watched dogs doing it several times, as sometimes people would bring bitches to our house and sometimes he would take our studs to theirs. My senior year in high school I got into watching bestiality porn a lot and would watch it after school sometimes. I’d close my door and my sister pretty much left me alone. She is about a year and a half younger than me.
One day I was jacking off to doggie porn and saw one of a chocolate lab doing a girl and had the idea of showing it to my sister. I was nervous about it, but I opened the door and jokingly said, “Hey, come here, you gotta see this!” and I had it up on my computer screen and I was sitting in front of the computer and when she came in I said, “Can you believe this,” and played the video.
She was like, “OH MY GOD! I can’t believe you just showed me that!” I was like, “Crazy huh?” and then I closed the video window and you could see the thumbnails for lots of other videos, and she walked up and grabbed the mouse and started scrolling trough them saying, “Oh my god, I can’t believe people do this.” Then she clicked on a video and was like, “Oh my god!” and then she just left.
I closed it all and went to watch TV, and she came in and sat on the other couch and just said “I can’t believe you look at that stuff,” then just left it at that and we watched some sitcom re-runs.
I was nervous then that she would say something to our dad, and was nervous all night and also thinking about it.
The next day, when we came home from school, I went to my room again and closed the door and started looking at doggie porn again. She knocked on the door and said, “Are you looking at that porn again?” I pulled my pants up and said no, and she opened the door and of course it was on the screen and she said, “I knew you were.” She came over and sat on the edge of the bed next to the computer and she was like “click that one”, etc. and we watched like 4 or 5 videos. By this time I was so horny I couldn’t take it, and told her we needed to stop and she left my room, then I went out and grabbed a snack, went back to my room and quickly jacked off then went back out.
Then it was the weekend and we didn’t say anything about it, but it was all I could think about and in the middle of the night I’d jack off to it. I just kept thinking that, clearly she was into it even though she acted offended by it.
So on Monday, when we came home I let our lab into the house, which wasn’t unusual, he was an inside/outside dog. I went to my room, left the door open, and started looking at doggie porn. Within a few minutes my sister came in, and our dog was in the room too. She sat on the edge of the bed again and we started looking at it again and our dog started getting excited. I think he could sense that she was getting turned on.
She was like, “Oh my god,” trying to play it off and saying, I can’t believe you let him in here, etc. we were kind of giggling because he was getting worked up and going in circles and he was starting to lick her legs and just licking like crazy and wanting to be petted, etc.
She was wearing a t-shirt and like gym shorts, and he started shoving his nose into her crotch and licking and she was moving back saying “Oh my god!” She had scooted back on the bed and then he put his front paws on the bed and was still trying to lick her. I looked down and could see his cock starting to come out.
Then, she just kind of spread her legs and let him start licking her through her shorts. I looked at her face and she just had “that look”, she was staring right at him. She started scooting back to the edge of the bed and then she just pulled her pants down to her ankles. I couldn’t believe it. I was sitting right there like 2 feet away. I just backed up and didn’t say a thing. I’d only had sex with 1 girl before that and even then we mostly fumbled around in the dark when we did it. So this was like the first real pussy I’d gotten a good look at. She was shaved.
She kept her legs kind of together at first, and he was going crazy by this point, licking her a lot. She was like breathing heavy out of her mouth, then she just spread her legs as wide as she could and pulled them up in the air. I was practically cumming in my pants by this point. She was just panting and shaking and saying, ” Oh my god, oh my god” over and over.
She glanced at me, then she just got down on the floor on her hands and knees and he mounted her right away. She shrieked and was like, “Oh fuck,” and let out a few more high pitched shrieks. I wasn’t sure what to do at that point, but then he started really pumping hard and she was just saying “Oh fuck, oh fuck, oh fuck.” She was facing away from me, so I was mostly just seeing the dog’s back end humping her. I pulled out my cock and jacked off and came in like 2 seconds, which I don’t think she was ever aware of.
After a couple minutes he stopped, and she was panting saying, “oh my god, oh my god. Holy fuck.”
He stayed on her for a bit, then she started trying to get up and she was like, “Oh my god, he’s stuck in me.” I think she was worried then, but after a few more seconds he got off her and when he pulled out I saw her pussy gaping wide open right before she stood up. Then he started licking his cock and I could see his huge knot. She just kind of ran out of the room. Then I heard her crying so I went into her room and said, “Are you okay?” and she was like, “I can’t believe I just did that. Don’t tell ANYONE!”
I was like,”I’m not going to tell anyone.” She said it hurt and she was never going to do it again.
I put the dog outside, and she avoided dog for a long time after that. We never talked about it or anything, but I thought about it all the time it was so hot.
About 4 months later we were outside in the woods after school one day with our lab, and we were playing around and he was getting frisky again and she sat down and spread her legs and he started licking her again and I just stood there, and she took her pants off again and let him lick her, then she got on her knees again and he mounted her. This time she was looking at me, and I pulled out my dick and started stroking it as she watched. This time she wasn’t shrieking and she was clearly enjoying it and saying, “Oh yeah, oh yeah,” and I when he stopped I came hard and shot cum all over the ground.
Then she got up and just said, “Don’t tell anybody,” and put her pants on and went back into the house.
I’ve wanted to fuck her so bad after that. We never talked about it, and I’ve since moved out of the house, but fuck I think about it all the time
