In the barn loft

Siblings have fun in the barn. Mom finds them

Gigi is a 47-year-old woman who is divorced and has a teenage son Mike and a daughter Helen. They also have a German shepherd dog named Joe.
They live near a small village in Illinois in a rented house that was a farmer’s house until he died and his heirs sold the land to a neighbor farmer who didn’t need the land it was on for farming.
Living in the country like that afforded them a lot of privacy, which was good because they were a very loving family.
I’ll describe each member.
Gigi was what could only be described as obese. She was 5’3” and weighed 250. Her belly hung over her abdomen and her humongous tits hung down to her belly button.
Mike is a skinny teen with acne who has never had a date.
Helen is a teenager too and one year younger than Mike. She is the opposite of her mother, she is 5’8” already. She has medium sized boobs that don’t sag at all and she has an ass that attracts attention wherever she is, including that of her brother.
On the parcel of land they lived on there was a barn that the farmer used for hay storage but didn’t visit often so Helen and Mike used it for a large play house.
So one day they were in the barn and they climbed into the loft. They had a blanket stored there to use so the hay didn’t scratch them when they sat on it. Usually they would use the space to relax and get away from their mom if she was in a bad mood.
This day was hotter than usual and Helen was wearing her very short shorts that showed the bottom of her ass cheeks and a halter top. They were laying on the blanket just looking at the ceiling and talking about what they wanted to do that day. Mike looked over at his sister and it struck him how sexy she was looking. He had never considered her as a sexual partner but as he looked at her he started to get turned on.
“Uh, Helen? You look really sexy today.”
“Well, thanks Mike, but that’s a bit weird coming from my brother.”
“But it’s true! I can’t help it if I think you’re sexy. You are!”
“Well, you’re not bad yourself. If you weren’t my brother I’d go out with you.”
“Well, why don’t we pretend I’m not your brother.”
“Okay, so what would we do if you weren’t my brother?”
Instead of answering, Mike rolled on his side and pulled his sister to him, kissing her. At first Helen resisted but after Mike ran his tongue across her lips, she opened her mouth and let him lick her tongue. Her head started to spin as the kiss became more passionate. She ground her cunt against his hard cock as Mike put his hand on her boob. Mike pulled her top up, revealing her braless boobs. He twisted her nipples with his fingers. She moaned into his mouth and reached between their bodies to rub his cock.
They were both virgins but at the moment all they wanted to do was fuck each other. Mike unbuttoned Helen’s shorts and she unbuttoned his.
They both pulled their shorts and underwear off.
“Oh god Mike! Do me! Hurry! I want you to fuck me!”
That was when Joey, their dog came bounding up the stairs. He often came up to the loft when they were up there.
When he got near them he caught the odor of a female in heat. He followed the scent and was puzzled that it was coming from a human female!
Mike and Helen didn’t hear him come so they were startled when he put his snout between Helen’s legs. Mike jumped up and Helen scolded the dog, “Joey! Bad doggy! That’s not for you!” She tried to push him away but he now considered her his bitch! He growled, baring his teeth.
Mike tried to pull him away but Joe snapped at him, thinking he was trying to steal his bitch.
Mike and Helen were afraid that Joey would hurt them so they let him do what he wanted.
Joey started to lick Helen’s cunt. His big tongue lapped from her asshole to her clit.
“Ohhhhhh god Mike! He’s gonna make me cum!”
His tongue was delving into her hole and she was pushing up against it.
She thought that was all he wanted, but Joey wanted to breed his bitch!
He tried to mount her while she laid on her back but couldn’t get it in. He pushed on her side, trying to get her to roll over. He growled again and she again feared that he would bite her so she rolled over and got on her knees with her head on the floor.
Joey had her where he wanted now and jumped on her back. He grabbed her around the waist with his paws and started to stab his cock at her cunt. He missed the first several times but then he hit the mark! He felt his cock sink in and shoved all 8 inches into her virgin cunt!
“Ohhhhhhhhh god!” Helen screamed, “oh god! It hurts! He’s so deep!”
Despite the depravity of the situation, Mike was hard as he watched the dog hammer her cunt!
After a minute of hard fucking, Helen started to feel pleasure deep inside her cunt.
“Ohhhhhhhhh no! I’m gonna cum on his cock! Ohhhhhhhhhhhhh god!”
Mike was beating off while watching her push back. He could see the big dog cock going in and out of her cunt.
Then the dog threw his head back and howled as he emptied his balls into the bitch!
After he finished, he jumped off and laid down to clean himself. Mike took the opportunity to fuck his sister! He got behind her before she could get up and shoved his cock into her cum soaked cunt.
“Oh no Mike! It hurts! Oh god Mike!”
“I’m sorry Helen! I have to! I’m so fucking horny!”
Helen put her head down again and let Mike fuck her.
Mike couldn’t believe how good she felt! He started to fuck faster and Helen began enjoying the feeling when Gigi came in the barn looking for them. She heard them in the loft and walked up the stairs, shocked when she saw Helen on her knees, bent over with Mike fucking her!
She was still on the stairs, her head just high enough to see them. Then she saw Joe laying near them, licking his big cock.
She was even more shocked at her reaction to the scene. Instead of being angry with them, she was getting very wet. She reached down and started to rub her pussy through her shorts as she watched Mike’s cock saw in and out of Helen’s cunt. She hadn’t had a man for too long and in a daze she climbed the remaining steps and approached her children. They didn’t see or hear her coming, so when she reached between Mike’s legs to cup his balls, he jerked out of Helen’s cunt!
“Oh god mom! I’m sorry! I just couldn’t resist!”
“It’s okay, Mike, but you can’t leave your sister frustrated. Get that hard cock back in her until she cums!”
Mike. Couldn’t believe this was happening! He shoved his cock back in and Gigi resumed massaging his balls.
Helen moaned, “oh god mom! It feels so good!”
“I know baby. But don’t cum in her cunt, Mike. After she cums you can fuck me and cum in my cunt!”
Mike fucked Helen until a few minutes later, she moaned, “Ohhhhhhhhhhhhh yes! I’m getting it! Ohhhhhhhhhhhhh good yes!”
Mike had to concentrate so he didn’t cum in her.
When she finished her orgasm, Gigi got in her place and Mike shoved his cock in his mom’s cunt.
“Ohhhhhh yes Mike! Fuck me! Fuck mommy hard! Oh good yes! I need it! I need your cock! Ohhhhhhhhhhhhh yes baby! Fuck me!”
Gigi kept talking dirty as he fucked her. Helen watched, still fingering her cunt.
Then Joe saw an available bitch and walked over and started to lick Helen’s cunt again. Helen got on her hands and knees and Joe found her hole quickly.
Gigi moaned, “Ohhhhhhhhhhhhh god! You’re fucking the dog! Oh fuck! That’s fucking hot! Ohhhhhhhhhhhhh yes! Ohhhhhhhhhhhhh god! I’m cumming!”
Mike blowed at the same time, “yeeeeaaahhhh mom! Filling your fucking cunt! Ohhhhhhhhhhhhh yes!”
When they finished they watched Joe fucking Helen. Gigi couldn’t believe her little girl could take that big cock so easily! She was jealous as she watched the big cock fucking Helen.
Then Joe jammed his cock knob into Helen and filled her with cum!
“Oh god mom! He’s so deep! Oh god!”
When Joe pulled out, Gigi knelt behind Helen and sucked the dog cum from her cunt.
They all laid on the blanket and hugged each other, knowing they would have many sessions like this
