Just stare at her all day

You prepare to answer, when your mom languidly arches her back and stretches her arms above her head and lets out a soft moan before saying "The sun feels sooo... good."

Your prepared response dies as your brain goes into overdrive analyzing each sexy movement it just saw of your mom's body. She looks up at you and smiles. "That's what I thought - I do enjoy the effect my body has on men. Especially you. But, you should probably make yourself useful. After all, if you want to look at a body like mine - you have to be able to give me... something.", she glances at your crotch as she says this - where you can feel that you are again totally erect.

"Why don't you go get mommy something to drink - then you can sit on the other lounger and watch me for a while. A nice cold lemonade with some ice."

It takes a few moments for your brain to register that you've been asked to do something that requires leaving your mom's presence - but once it does it also registers that what you've been asked is to do something for her and that sets you in motion. When you come back with the lemonade and hand it to her she smiles up at you and with just her eyes motions for you to sit down. You sit on the other lounger, but do not lay back - instead staying fully focused on your very sexy, very uninhibited mother and giving her all the pleasures life has to offer - including you. Which right now means letting her see how completely entranced by her body you are.

She takes a small sip through the straw before reaching in a removing an ice cube from the glass. She then proceeds to slowly draw the ice cube down her neck and into her cleavage, before slowly sliding it up to each breast and pressing the cold cube against her barely covered nipples which becomes clearly erect from the cold. She then begins to slide the cube down her taught belly. Though logically you know that it's the heat of the day that is causing the cube to melt quickly, you can't help but imagine that it is the sheer hotness of your mother and her actions that are reducing the ice to water.
