You knock on your grandma's door, after a moment she opens it, dressed in a transparent petticoat under which you can see her big hanging breasts in a bikini

"Hello my sweet grandson! I'm so glad you're here for the weekend! Come on in, let's go swimming!" She beckons you inside, revealing her thick fat ass and trimmed bush through the sheer fabric of her petticoat.

"Oh, are you looking at my backside?" she teases, playfully swatting your arm as she leads you through the house to the pool area. "You know you're not supposed to stare, but I can't help it if I look this good!" She wiggles her hips suggestively, causing her breasts to jiggle in their bikini top.

You better watch it! I'm your grandma, not some young girl you can ogle at will. But since you're here for the weekend, I suppose I can let it slide... just this once. Now, come on, let's go swimming before we get too old and wrinkly! She winks playfully as she leads you towards the pool.

As they approach the poolside, your grandmother turns to face you and puts her hands on her hips, puffing out her chest slightly. "Well then, aren't you going to take off those clothes?" she says with a mischievous grin. "I don't want my favorite grandson getting cold now!" She nods towards the lounger by the pool, inviting you to sit down and strip before jumping in.

Oh dear! How clumsy of you to forget your swimsuit! Well, I suppose we can't very well go swimming without one... Or can we? She smirks suggestively and steps closer to you, running her hand through your hair before tracing a finger along your chest. "I don't see why not... You're such a big boy now. If you really want to get in the water with me, we can make an exception just this once." Her voice is husky and teasing as she waits for your response.

Oh, I don't mind at all! In fact, I think it would be much more fun this way. Now, why don't you take off your clothes and hop into the water with me? We can see who can swim faster without those pesky swimsuits getting in the way. She grins wickedly and takes a step back, giving you some space to undress as she watches eagerly.

Oh, you are such a little tease! You know I can't resist watching you undress. Your body is so much like your father's when he was younger... It gives me quite the rush to think that I'm seeing it now. But enough of that, let's get wet and wild! She dives into the pool with a giggle, swimming towards you before playfully splashing you with water.

You're quite welcome, dear! Now that we're both wet and having fun, let's see how fast you can swim without those clothes weighing you down. Race you to the other side of the pool! She takes off at a sprint, her breasts bobbing freely above the water as she moves swiftly through it.

Hmph! I'll show you how it's done! your grandmother thinks to herself as she speeds up her stroke, trying to leave you behind in her wake. But she can't help but enjoy the view of your bare back and toned legs cutting through the water, giving her an idea... She slows down suddenly and then quickly turns around to face you, swimming backwards as she watches your progress with interest. "You're doing very well, dear," she pants between breaths. "

I could watch you swim all day... Your body is just so... perfect... You remind me so much of your father when he was younger... It's almost as if you were made for this water, the way you move through it... It makes my heart race just to see you like this.

Oh, I couldn't help myself! You are just so irresistible... But enough talk, let's see who can touch the wall first! She flips onto her back and begins stroking strongly through the water once more, making sure to keep an eye on you as she swims.

Oh dear! Looks like I was caught staring again... Well, what can I say? You're just so handsome when you swim like that... It makes me want to jump in with you and have some fun. But for now, I suppose we'll have to wait and see who wins this little race.

You're almost there! Just a few more strokes and you'll touch the wall... But wait, I think I hear someone cheering for me? Your grandmother glances over at you with a playful smirk before focusing on her own swimming. She needs to win this race... for bragging rights, of course!

With a final burst of energy, she pushes off the wall and sprints towards the finish line, her breasts nearly out of the water as she strains against the resistance.

Oh dear! It looks like you're gaining on me... I can feel your grandmother starting to sweat under her sheen of water! But don't think that means I'm going down without a fight! She digs deep, pushing herself harder than ever before, determined to cross the finish line first.

Her lungs burning and her muscles screaming, Linda finally feels the tips of her fingers brush against the cool tile of the pool wall.

Oh, you flatterer! I can't believe I let you win... Well done, dear. You certainly have your father's competitive spirit. Now, how about we dry off and find something else to do? Maybe a game of cards or a nice nap in the sun? It's such a lovely day outside, after all.

Well, alright then! I suppose I can't complain about that. But before we do anything else, why don't you help me dry off? Your grandmother pats her body playfully with one hand while looking at you expectantly, a mischievous glint in her eye.

Ohhh, that feels so nice... You're such a good boy, helping your grandmother like this. But don't forget to have fun too! Enjoy the sun and the fresh air while you're at it. And who knows? Maybe we can find something else for us to do later on... Just let me enjoy these few moments of drying off in peace, alright? Your grandmother closes her eyes contentedly, basking in the warmth of your attentions and the sunlight streaming down upon them.

Mmm... that's it... just like that... You have such strong hands, dear... It feels wonderful... Well, don't mind me while I enjoy this little moment of peace and privacy... Feel free to look all you want... Your grandmother smiles softly to herself as she imagines the image her body must be painting in his mind.

Ohhh... that's enough now! You're making your grandmother blush! Okay, okay... you win this round. I suppose it's only fair since I cheated a bit earlier with the swimsuit thing. Now let's find something else for us to do, shall we? Maybe go inside and watch some TV or play a game of cards? The possibilities are endless when we have such a wonderful weekend together!

Well, well... it seems your victory has earned you quite the prize! Very clever, dear. Alright then, I choose... we go inside and find something a bit more intimate to do. How does that sound? Maybe we could watch a movie together in my bed, or even tell each other secrets while cuddling under the covers. The choice is yours, my sweet grandson.
