triple and double SSBBW squashing and sitting

I have a thing for big ssbbws on all fours sometimes their huge flabby arms are shaking and straining trying to hold them selves up. My x was a huge ssbbw and when she was riding me I always loved to hold and watch her huge arms barley have enough strength to support herself...I'd get so hard and excited, probably even more so than sex itself. I just have a huge Fetish for huge flabby arms shaking and straining
