Mighty grandma

Grandma flexed her arm for me, such a big and ripped arm. She is at her 70s but her arm is so big and ripped, most guys only dream of having such arm. I had to feel it, so I did.

Grandma: "You look impressed John"

Son: "Grams, it's so ripped and big. How can you pull that off?"

Grandma: "By training hard enough. Looks like this old lady can still turn a boy on. Have a feel of my abs"

Grandma flexed her abs, she had those kinds of abs like a total brickwall. So ripped and so hard looking, built like a superhero. Grams had even well built side abs. I started to have a good feel. They are really hard yet feel so good, grandma's abs could take a good punch but also be something you want to rest your head to.

Son: "Ah Grams these are so hard. You must train your abs like crazy to get them like this"

Grandma: "Well I do train them like crazy John"

Son: "But doesn't that like hurt your back or..."

Grandma: "Well not anymore John. I maybe in my 70s but thanks to working so hard my body feels young which means my age does not limit me"

Oh my God, I was already getting so turned on but hearing from grandma that her age is not limit anymore made my mind go wild. I was imagining grandma wrestling and boxing against younger men and totally dominating while smiling with that sweet granny face.

I felt grandma's back, it's really big and feels so strong. Grandma is truly a muscle Goddess, at her 70s yet somehow at same level with mom. Grandma turns around flexing her mighty pecs.

Grandma: "Mmm you like grandma's big built pecs"

She was flexing them in such erotic display, pecs so big you might mistake them for tits. I went for it and felt them, this was first time I was feel chest of a woman. I was on edge, I don't think I can hold it.

Son: "Aahh grams I cannot...hold it anymore"

As she kept flexing them and I kept feeling her pecs, I started to feel myself cumming in my pants. Moaning as I shot my load and I shot a lot of cum. My legs were shaking hard from how good that felt, even though I just came I knew my body wanted to release much more in grandma's presence.

She gently got me on bed to rest. Grandma smiled looking at me, waiting for me to get some energy back. But just as I was going to get up grandma jumped on top. I have never seen such an old lady to jump in bed like a horny animal.

Grandma: "Though while my body feels younger thanks for my new muscles, it does not make me look younger. I still look like an old granny"

Son: "I don't mind that grams...actually I find it really hot. I find the contrast of you being granny yet so big and ripped....so hot"

Grandma looked at me seductively

Grandma: "That's nice to hear John, now looks like you get the pleasure of your virginity taken away by your...strong, beefy, big and ripped grandma"

She is making me even more aroused with her words. Somehow I could sense that she must be really good at this despite her age

Son: "Yes, grams. I want you to do it...I-I am ready"

She started to undress me on bed.
