Note: This story was dynamically reformatted for online reading convenience. My love affair with canine critters all started the summer between my junior and senior years in high school. I had a boyfriend, and we were sexually active. Our sex was pretty conventional, except for one respect. My boyfriend, who I will call Ron, had a kinky streak. He was beginning to explore his dominant side, although neither one of us, at this time, knew what that was. His domination was fairly simple. He liked to play in my panties or under my blouse in public, in a situation where I might be seen. Now, this was not nasty, just playful. But I liked the fact that someone might see me with Ron's hand in a sensitive place. And I also like the sensations when he touched me. Common locations where Ron liked to tease me where in the car, at the movies, at the park, or at the pool. I am fairly certain I was seen on several occasions. Once, at the pool, I am pretty sure some people saw us. Ron had his hand inside of my bikini. We were leaning against the wall, talking, and he put his hand down the back of my bottom, slowly working it in between my legs. Another time was in the park. I had on a short jean mini and a t-shirt that showed my belly. We were lying on the blanket, and Ron played under the t-shirt for a bit, and then moved under my skirt. I am pretty sure some people saw us. But you get the idea of how this little play went. Around July, Ron had taken his kink to a new level. At least it was a new level for us. His family had a big flat screen downstairs in the family room. There was also a small deck off of the family room. Ron started to play with me on the deck or when we were watching TV, while his parents would be upstairs. I found this very, very arousing. The thought that parents could catch me was very, very exciting. Well, one Saturday afternoon in early August the two of us went to the pool. We spent a couple of hours getting some summer sun, and then went back to his place. Ron decided he wanted some eye candy to look at. I had shorts and a t-shirt over my bikini, so I removed them. I didn't wear dental floss and band-aids for bikinis; I wore a regular bikini. This one was a red and white striped string bikini, with pretty much full coverage in the rear. But it was clingy. His parents didn't mind. We ordered some pizza, ate on the deck, and flirted. Ron had rented some bad movies, and after we ate we went into the family room to watch them. His Mom and Dad were upstairs. It didn't take long before Ron started to tease me a bit. What I didn't realize was just how different this session would be. You see, the family dog was a Rottweiler. We settled in and were watching the movie. I loosened my top, and Ron tweaked my nipples for a while. Then he moved down. I lost interest in the movie, as he was really applying a nice tease between my legs. In fact, my bikini bottom was down to my knees. Now, Ron would play and explore, inserting a finger every now and then. He knew where my pearl was, and would tweak it a bit, which made me jump. Every so often he would stop for a minute or two, and then go back to playing. I was pretty much enjoying the sensations. What I did not know was that the Rottweiler was in the room. During the pauses in his play, Ron was allowing the Rottweiler to lick his fingers. Well, I think this went on for about thirty minutes. I opened my eyes, saw the dog at my feet looking at me with its tail wagging, and I smiled. The Rottweiler barked once, jumped forward, and began to lick my mound! I was shocked and surprised. Ron was grinning from ear to ear. Now, you need to keep in mind that I only weigh one hundred and ten pounds and stand five feet one inches. A Rottweiler comes in at around one hundred pounds and is a very, very active and physical dog. I think my shock paralyzed me, and the dog was not about to be denied a taste of my juices. The fact was that I really loved that wet and rough tongue running over my mound. The dog also buried his nose in me a few times. He licked me for a few minutes and then got bored, or so I thought, and moved away. Ron was laughing, I was embarrassed but all tingly from the pleasure, and we were both shocked. What shocked us more was a few minutes later the dog came back for a second taste, and then a third. I don't think Ron had any idea as to how close I had come to a climax from the dog's licking. I had loved it. He had thought it was pretty wild, and enjoyed watching it. At the time, I had no clue. Looking back on this incident, I believe the family pet had experience with Ron's mom, and was pretty familiar with girls. I can't be sure, but it appeared to be ready to go. Well, that night and the next day Ron and I actually talked about it. Ron thought it was cool, and enjoyed watching. I loved the pleasure. Ron wanted to watch the dog fuck me. I said no. We argued a bit, going back and forth, and really didn't decide on anything. But I was really, really curious, and I think Ron sensed that. And he did want to watch. Well, the next week we took a break. It was my time of the month, and there was no sex. But Labor Day weekend was coming, and Ron's parents would be away. And I would experience my first sex with a dog.
