My amazing mom and grandma

I am John, 20 year old guy who lives with his mom. I was once again checking muscle women on my laptop, masturbating on my own. Nothing to me is hotter than a woman who is built, I don't mean some slightly fit "fitness girls" I mean full on beefy female bodybuilders who easily outmuscle me.

The way the woman infront of camera is half naked, flexing her big muscles with a seductive smile. Oh my God...doing the most muscular pose and to make it better it seems that she is well in her 40s. She repeats the pose 3 times and on 3rd I felt myself cumming.

John: "Aaahh"

*Knock knock*

Oh good that I locked the door. Mom would have seen if it was not locked.

Mom: "John dinner's ready"
John: "Yes mom"

Glad this time I made it. Many times I would have had to stop mid way through.
