Brothers Do Love Sisters Part 3

Dan had been getting a shitload of pussy lately, with his little sister being horny ALL the time and Stephanie taking him out and fucking him silly. He was taking vitamins and working out regularly just to keep up with them. Things were about to get even crazier if that were possible.

This is Dan’s story….

I had gone into town this morning to pick up a couple parts that I needed for my truck. I also had stopped in the local restaurant and had a big breakfast. I was pretty content and figured I would have an easy day working on the truck. I pulled it into the shop and decided I would let it cool off a bit and walked over to the house.

I entered the kitchen through the back door and it appeared that there was nobody home but me. I was headed back to my room to get an old t-shirt to work in when I heard my sister Jennifer moaning. Of course, I had to check it out, so I carefully walked down to her bedroom door. The door was open and when I peaked around the corner I fucking near passed out!

There was my hot little sister, her feet were on the floor and she was bent over and face down on the bed with her sweet ass sticking out and Sam, our big black Lab, was licking her pussy and ass like an ice cream cone! Jenn was moaning and had a hold of the pillow trying to muffle hear moans, but it wasn’t working. Sam was working hard trying to lap up all the sweet girl juices that were running down her legs. I wasn’t sure who was having the most fun, her or the dog. That was when I saw the big red dog cock dangling below Sam. It must have been about a foot long and was about as fat as a cucumber.

Jenn turned her head towards me and she opened her eyes and saw me standing there watching. She screamed and scared Sam, and she tried to cover herself, but I had already seen plenty.

“What the fuck are you doing here?” she asked as she turned rosy red with embarrassment. “I thought you went to town.”

“I did go to town. It looked like you and Sam were going to town too.” I laughed.

Sam came to me and I petted him and then he went back to Jenn and tried to get her to let him go back to work on her pussy. He kept trying to get under the blanket to get to his prize but she kept the blanket wrapped around her legs.

“I’m so embarrassed” she cried “I can’t believe you found us like this. You gotta promise not to tell anyone Dan, you gotta promise me.”

“Don’t worry, I won’t say a word as long as you let me watch.” I promised. “How long have you been doing this little deed sis?”

“This is only the second time. I let him do it because he made me feel so good the first time.” She explained to me that she had been laying in the back yard tanning the day before yesterday and had taken her bikini off to avoid tan lines. Jenn said she must have dozed off and Sam had come up behind her and sniffed her sweet pussy and he just started licking it. She said it startled her and she woke up and rolled over and Sam got his nose between her legs and was licking her vagina. She tried to push him away but he was on a mission and besides she said it really felt great.

Jennifer told me that she came about six times before she finally got on her feet and ran into the house. Sam followed her but she closed the door and left him outside. She said he was whining and barking, but she was scared to let him in until she got dressed. She thought he might try to fuck her. She said she let him in later and he sniffed her and she kept yelling at him until he left her alone.

Today when she got out of the shower and was walking around in her room, Sam came in and when she petted him, he gave her pussy a big lick and she couldn’t resist him. She said it had only been a couple minutes before she saw me, but she had already came twice!

“Let him lick you some more Jenn, I want to watch.” I pleaded.

“I will if you promise to get him off me when I have had enough.” She said. “You can’t let him try to fuck me.”

“I promise I won’t let him fuck you, but I can’t promise you that I won’t try to fuck that sweet little pussy.” I told her as I winked at her.

She pulled the blanket off her legs and Sam was all too happy to continue where he had left off. I realized then that my cock was hard as a rock and I quickly dropped my pants and began to stroke myself. I stumbled to the bed and sat next to Jenn where I could watch Sam lick her to another orgasm. Sam stopped and looked at me and then he licked my cock and went back to licking Jenn’s cunt.

“Didn’t that feel great?” Jenn asked, “I saw him lick your dick. It feels great doesn’t it?”

“Wow, his tongue feels like sandpaper.” I giggled, “It feels great!”

Sam continued to work Jenn’s pussy into a wet mess until he figured it was time to fuck. When he tried to mount her, I managed to get him off of her before he could get inside her. He growled at me and She managed to get the blanket around her legs and after a couple minutes he gave up and went over by the window and laid down and began licking his big red cock.

Jenn and I watched as Sam licked his dick clean and slowly it shrank back inside its sheath and he stretched out and went to sleep.

“Do you think he would actually fuck me?” Jenn questioned, “Do you think he would? Could he make me pregnant or would I get some kind of disease from him?”

“I don’t know” was all I could answer, “We will have to check it out and see what we can find. You know everything is on the internet.”

My cock was so hard it was about to burst as I continued to stroke it. I was suddenly aware that Jenn had rolled over beside me and she reached out and took my manhood in her hand. She smiled as she stroked it and then smiled at me and said, “No sense in wasting this perfectly good hard-on.”

She opened her mouth and slipped my cock into her warm and waiting mouth.
