Dog sitting

Karen was sitting on her porch when her neighbor, Mrs Grimes stopped by to ask if she would watch their dog while they were gone for the weekend. Their dog knew Karen very well so it wouldn’t be a problem.
Karen asked her mom if it would be okay.
“You’re 15 years old honey. I think you can manage.”
So on Friday afternoon Karen went over to get instructions on care.
Mrs Grimes showed her where the dog food was and how much to feed him.
“As you know, he’s very friendly. If he gets too friendly just tell him down boy and he’ll stop. You can use the pool as much as you want, just be careful.”
Karen didn’t know how Duke could be too friendly. He was a big Great Dane and very gentle. He always came right up to Karen and wanted to be petted.
After making sure Karen knew what to do Mr and Mrs Grimes left for their trip. It was around noon so after lunch she put her bikini on and went over to the pool.
She laid her towel on the chaise lounge and then put sunscreen on. She put the lounge back and laid down to soak up the sun. She had fallen asleep and was dreaming that a boy was licking her pussy. It seemed so real that she opened her eyes to see Duke licking her pussy through the thin bikini bottom.
“Duke! Bad boy! Down!”
Duke was confused. His mistress always let him lick her. He sat back, frustrated.
Karen saw that she had made him sad. She patted the lounge beside her and Duke got up to walk over to her.
When he did she saw his cock. It was huge! And there was an even bigger bulge at the base!
Duke was whining in frustration and Karen felt sorry for him. She was not a virgin and was familiar with frustrated boys.
“I’m sorry big boy. You just surprised me.”
She petted him on his back, still looking at that big cock. It was twitching as she petted him. She couldn’t resist touching it. She could just get her hand around it and when she used both hands there was still cock visible!
Duke pulled away and started to lick her cunt again.
“Oh yes Duke! Lick my cunt!”
Karen pulled the crotch of her bikini bottom to the side. The first lick on her naked cunt made her moan and tilt her hips up to give him more access.
“Oh god! Your tongue is so good! Ohhhhhh fuck yes!”
After a few minutes of licking, Duke jumped on top of her, pushing her upper body down.
Karen wasn’t ready for that, but he was humping with his big cock stabbing at her crotch, searching for her hole. After several misses, his cock found its target! Duke felt the sheath open to his cock and thrust forward, burying his cock with the knot pushing at her cunt.
“Ohhhhhh god! Ohhhhh god! It hurts! Ohhhhhh god!”
Duke started fucking with short, rapid strokes.
Karen grabbed the edge of the lounge chair and pushed her cunt to meet his strokes.
She was moaning and dog cum was splashing all over her thighs as he slammed into her.
Then after several minutes he pushed hard and his knot lodged in her cunt.
“Ohhhhh no! Oh god!” She moaned as the knot sealed her opening. Duke was spewing gobs of hot cum into her, filling her cunt. Karen was cumming violently, her legs shaking and her head thrown back.
Duke left his cock lodged in her for several minutes. It felt so good she didn’t want to take it out but finally Duke lifted off, his knot popping out and a river of cum following.
Karen was exhausted from the extreme fucking and fell asleep, cum still oozing fro her red and open cunt.
She was awakened by someone gently shaking her shoulder.
It was Mrs Grimes.
“Wake up honey! You’ve got a bad sunburn, not to mention the dog cum leaking from your pussy!”
“Oh god! I’m so sorry!”
“It’s okay honey, I know from experience that Duke is hard to resist. I just love that tongue! And judging from the cum running from your cunt, you know how special his cock is!”
She took Karen by the hand and led her to the house. Once inside she got the aloe Vera lotion and spread it over the sunburn.
“Let me take your bikini off honey so I can put some lotion all over your sexy young body.”
Karen had never done anything like this with another woman. But she really liked how it felt to have the older woman rub her body. She lifted her hips to let Mrs Grimes pull her bikini bottom off. Then she untied her top and pulled it away.
“Oh Karen! You have a beautiful young body!”
“Thank you Mrs Grimes. Mmmmm, that feels good!”
“Call me Joan. I’m going to make you feel really good honey!”
She rubbed lotion on Karen’s boobs, twisting the nipples.
“Oh god yes! Oh yes Joan!”
Then Joan trailed her index finger down Karen’s torso. She spread her pussy lips and flicked her clit.
“Ohhhhhhhh yes! Oh yes! God yes!”
Karen moaned as Joan shoved two fingers into Karen’s cunt.
Joan worked her fingers in and out, rubbing her clit with her index finger of her other hand. Karen was loosened up from the fucking that Duke gave her. Joan used all four fingers and shoved her hand in to the knuckles.
“Oh my god Joan! Oh god yes! Oh yes!”
“I told you I was going to make you feel really good.”
Joan tucked her tune into her palm and twisted her hand until it was in to the wrist.
“Ohhhhhhhh fuck! Oh yes! I love it!”
Joan started pushing her fist in and out while rubbing Karen’s clit with the other hand.
“Oh yes! Oh god! I’m cumming! Oh god yes!”
As Karen orgasmed, Duke had come in, smelling pussy again. He saw his mistress with her ass in the air.
He started licking her through her shorts.
“Oh yes Duke! Lick mommy’s cunt!”
Joan pulled her pants down and Duke licked her bare cunt.
Karen was cumming nonstop as she watched the big dog licking Joan.
Then Duke jumped on Joan’s back and buried his cock in her cunt in one savage thrust!
“Ohhhhhhhh fuck! Oh god yes! I love that cock! Oh god yes Duke! Fuck me hard!”
Duke was fucking her with deep rapid strokes. Joan was still fisting Karen’s cunt she pulled her hand Al the way out the shoved it back in, pushing it as deep as it would go then going in and out as fast as she could.
“Ohhhhhhhh yes! Ohhhhhh yes! I’m cumming so fucking hard! Oh god!”
Duke slammed his cock in harder and his knot popped into Joan.
“Oh yes! Oh god! Karen! His knot is in me! Oh god! He’s cumming in me! Ohhhhhh god! I love his cum in me!”
Karen was delirious from the almost continuous orgasms she was experiencing. Her eyes were rolled back and her legs flopping around.
Duke finally stopped cumming and pulled out, his cum spurting from Joan’s cunt.
Joan pulled her hand out of Karen’s cunt and kissed it then kissed Karen on the mouth.
Karen hugged her, “oh god Joan! That was incredible!”
“Oh Karen, we’ve only just begun!”
