My name is Karen. I’ve always been a chubby girl and growing up I rarely went out with friends. When I was 17 I lost my virginity to my little brother, Scott and his best friend, Steve. I continued experimenting sexually with Scott for the few weeks. Soon after my mom found my diary. At first she seemed upset but after forcing me to eat her pussy and give her an orgasm our own mother/daughter relationship started to bloom.

 
 

My mom’s name is Sally and she is 41 years old. She is a full on BBW. She is very pretty, but had been on her own since dad left home 10 years ago. She finally had a new lover. Her own daughter.

Mom told me that she understood why Scott and I had been doing what we had. She told me incest ran in our family and that she and my Grandma Barbara had been having regular sex sessions since she was 16 years old.

I asked mom if I could visit grandma and she said she’d take me at the weekend. My mom told me she would need to visit my granny by herself first and that she would need to show her my diary. I hesitated but the thought of my own grandma making love to me soon made me hand over my diary.

I wondered what it would be like to be with woman in her 60’s. Grandma was also a BBW but had gotten a bit smaller as she had gotten older. Her hair used to blonde but was now mainly a silver grey.

On Saturday morning mom drove to me to grandma’s house.

“Now listen Karen. She said. Grandma wants to see you alone this weekend, so I won’t be staying. She added.

“What will you doing Momma? I asked.

“I’ve got a little surprise for that brother of yours. If his cum is as sweet as you say, I’m going to milk him dry all weekend. She then laughed. I could only imagine the time Scott was going to have.

We arrived at grandma’s house and she met us at the door wearing her bathrobe and had a warm glow in her face. My mom said to granny, I can’t stay. I’ve got a young son at home that will be missing his momma.”

“Maybe you could bring Scott next time. The family should see more of each other. We all stood silent then we giggled. Momma then left to drive home.

Grandma invited me inside and into the kitchen. On the kitchen table was my diary. It was open on the page with my latest entry. I had written in detail how momma had forced her pussy into my face and made me eat her until she came. I had even written how she had cried afterwards.

Grandma said, Take a seat Karen. I sat down at the table.

“I was just enjoying your diary. She pointed at the book then opened her robe to reveal her body. She was wearing blue panties but nothing else. I could see a dark wet patch in between her legs.

I looked up at her and she smiled. She put two fingers under my nose and I could smell the musky scent of her pussy. She stood next to me and put her hand inside her panties. I could hear the wetness and squelching. She took her hand out to reveal the same fingers, but now they were glistening.

“Taste Granny Barbara, baby. Taste your Grandma, there’s a good girl.”

I sucked her fingers and felt those sudden urges of taboo and regret come flooding back. This was so wrong, but it felt so good.

“Get up I’ve got a surprise for you. She said. She led me into her bedroom where she had set up a video camera pointing at the bed.

“Today Karen we are going to make your momma’s birthday wishes come true. It is her birthday soon and she has asked me to record her mother and her daughter, together. Grandma told me.

“OK. I replied.

“Get undressed sweetie. She said. So I did. Granny took off her robe and panties too.

I sat on the bed and grandma turned on the camera.

“Let’s sing happy birthday Karen. We sat on the bed naked singing happy birthday to the camera. Then grandma looked me in the eyes and said, Let’s get started.”

I moved into kiss her but granny said, Not yet. She leaned over to her nightstand and picked up something. It was a set of handcuffs.

“Let’s give momma a real show. Said grandma.

She put the handcuffs on me and cuffed me to her bedposts. I was on my knees facing the wall. The feeling of helplessness turned me on. Granny moved in behind me and kissed my neck. Then she went away again. I heard her open a draw and making noise. I couldn’t see what she was doing, but then she said, I’ve got a surprise for you Karen.”

Her fingers ran of my wet pussy and then I felt the head of a plastic cock start to push inside me. My grandma was about to fuck me with a strapon. The head and shaft were much bigger than what I was used to and it hurt like crazy but soon granny’s thrusting motions had my pussy accepting the long shaft. I was being stretched but it felt so good.

“Do you like it when your grandma fucks you Karen? Granny demanded.

“I love it, I love it! I gasped.

She fucked me doggy style for a while and I could feel the orgasm rising.

“Good. You’re nice and wet now. Time for some fun. Granny said. I heard the cap of a bottle open and then felt cool liquid running over my asshole.

“I’ve read your diary BITCH. I can’t believe you were fucking your brother for 3 weeks and never even tried it in the ass!”

“WHAT! I shouted. ARE YOU SERIOUS?”

Grandma laughed loudly and started to work a finger into my ass. One finger didn’t hurt much but when she moved onto two and three fingers I was starting to feel pain.

“I’ll be gentle. She spent a long time work my asshole and she kept the strapon moving inside my wet pussy.

She stretched my asshole out and said, I think you’re ready. You’re such a dirty cunt Karen. Letting your mother and brother fuck you. Now it is my turn and I am going to make you scream as I rape your ass!”

She took out the strapon from my pussy and eased it into my ass. It really did hurt, but she would stroke my pussy and the pain and pleasure mixed into one, heightening the feeling.

She started slowly but soon my asshole was accepting the entire length of the strapon.

My granny pounded my ass and reached around to play with my clit.

“Who is my little BITCH? Grandma screamed. Who is my little incest WHORE?”

“Me. I gasped.

“Tell me you’re my Incest Whore, tell me what you are”

Granny was being so forceful and rough. I screamed, I’m your Incest Whore! I’m your nasty granddaughter! Fuck me Grandma, FUCK ME!

“Beg me to rape your ass you slut!” She snapped.

“Rape my ass Grandma! RAPE MY ASS HARD!” I cried.

“Sing happy birthday to your momma Bitch! She shouted.

Now I was crying but I still sang happy birthday for my mother, even if the song was filled with me whimpering and screaming.

I nearly blacked out when I came. I could hear granny laughing as she fucked my ass as hard as she could.

She withdrew the strapon and unlocked the handcuffs. I was lying on the bed, sore and exhausted having been ass raped by my own 64 year old grandmother. She looked and me with a stern face.

“You’re not finished until you clean up the mess She said firmly.

I was confused. Mess? I said.

She looked down and pointed at the glistening shaft. It was coated in my pussy and ass juices. Clean up this mess you filthy whore and I’ll let you have a rest.”

My head was already swimming and I didn’t stop to think. I sucked the plastic cock and tasted my ass.

“Deep throat it whore. Gag on your ass juice for Granny!

I gagged on the cock and soon I collapsed through sheer exhaustion.

“Get some rest then you slut. You will need your strength for tomorrow.”

Grandma stood up and went over to the camera. Happy birthday Sally. She said.

She kissed the camera lens then she turned off the camera. I had no idea what she had planned for tomorrow, but I couldn’t wait to find out.
