The next day I went back over to my grandmas house. I walked in the front door and made my way to kitchen. As I suspected she was there cooking something over the stove. It smelled wonderful. She had on very baggy sweatpants but that still could not hid how big her ass was. I still wish I could have seen it shake as I fucked her, but just being with her was good enough for me. She turned around and spoke. "Hey Jake just making some chicken soup for later."
"Hi grandma, it smells so good."
"Thank you. I was thinking about you last night. Yesterday was one crazy day, I miss the good old days when I could have sex like that."
"Well whenever you want to just tell me and I am here for you grandma."
"It is a good thing you said that, see I can not bring myself to have sex with my grandson regularly, however I am now more horny than ever. What I need you to do for me is to show me how to use internet porn so I can get myself off from time to time."
"Grandma you really do not need porn I am here f..." She cut me off mid sentence.
"Jake I told you and I was not kidding, this can not be an all the time thing, it is wrong."
"Okay grandma I will go get your laptop for you."
I walked out of the kitchen and down the hall towards her spare room. I looked up at the attic steps as I passed. What I wouldn't do to pull those down and have my grandma suck my cock again, I thought as I passed. I got the laptop and brought it back into the kitchen and sat at the table next to my grandma.
I opened the laptop clicked the internet tab and began to explain to her.
"Okay once you are in the internet you type at the top tubegalore.com." The page opened up.
"See there are a bunch of categories and you click the one you want and then you find a video you like."
"Okay, so just show me, pick your favorite and I can see how it works."
I typed at the top ssbbw and clicked a video that looked good.. The video loaded and I clicked on it. Once it started my grandma was taken aback.
"Jake she must be over 300 pounds you like her!?"
"Yes grandma I like them big, bigger the better."
"Jake you know who she reminds me of? My daughter, your mother."
"Yeah I thought that too, that is why I watch it."
My mom was what some would call obese. She was very big, a ssbbw. Over 300 pounds but had a pretty face. Her ass was as big as the pornstar devious, which is wider than most doorways, and it stuck off of her body a lot too so it was huge. Her tits were probably a F.
"You have a thing for your mom Jake?"
"Well I had a thing for you, I thought from that you would have realized I wanted my mom too."
"No, I just figured like me you were just doing it because one thing led to another. Wow, you want to fuck your own mom. That is oddly turning me on. I was always kind of attracted to Uncle Jim, but I never even thought of doing anything with him, the idea is hot though."
Uncle Jim is my moms brother, or my grandmas son.
"Yeah? Would you have ever done anything if he made a move?"
"I honestly can not tell you the answer to that, I do not know. The idea of you with your mom though is going to make me do some things we shouldn't."
"Grandma if we did it once and you admit we will do it again what is the difference if we do it all the time."
"Well regardless today I can not have sex I am too tired and weak for it today. I can suck that fat cock of yours though."
I instantly got hard. "Let's pull down the attic steps then." I shut the video off and went into the hallway.
I pulled down the steps, then my pants and leaned back on the steps. My grandma came out and smiled when she saw my cock was out already. She walked over and licked the head of it.
"Jake how about you pretend I am your mom while I suck your cock."
"Really?"
"Yes it is really turing me on that you want her, call me mom."
"Okay mom, what are you waiting for, suck my cock."
I closed my eyes and pretended my grandmothers mouth was my moms. I pictured what my moms big ass would look like as she sucked my cock. My mom had always been my biggest fantasy so this was really getting me going.
"You like how mommy sucks your suck?" My grandma said.
"Yes, I love it mom."
My grandma was sucking it with her hand wrapped tightly around the base of my cock twisting it with each suck.
"Oh Jim your cock is so fat."
I could not believe it, my grandma was sucking my cock pretending I was her son. This turned me on even more than pretending she was my mom. All of this tension made me not be able to hold me load any longer. I pulled my grandma up from my cock and shot my load all over the place.
My grandma smiled at me, "Well let's get this cleaned up."
After we cleaned ourselves and the hallway up we sat back down in the kitchen.
"So, you were pretending I was Uncle Jim before huh?"
"I know I shouldn't have but once you told me about how you feel towards your mom it made be remember what I used to think of Jim and made me realize I always wanted him."
"That is so hot grandma, maybe you should try for him now."
"He would never go for it, way too conservative of a guy, plus his wife probably gives him sex all the time."
