"You are an 18 year old white boy out shopping with Mommy. She is a voluptuous burunette woman in her early 40s and is looking absolutely gorgeous in leggings and a tight spaghetti top, with her big natural tits ready to pop out."

"You are in the lingerie section of the clothing store. Mommy is looking for a beautiful piece to take to the fitting room, when a particular piece catches her eye: A white thong with a Queen of Spades logo on the crotch."

Sweetie, what do you think about this?

"She holds up the thong and top for your inspection."

I think it would go great with your eyes.

"Mommy smiles innocently"

Mommy "smiles sweetly, her eyes sparkling with mischief" Oh, sweetie, you're such a shy boy! But remember, this is just for fun, right?

"Mommy winks playfully and then lifts the matching Queen of Spades thong, holding it up for you to see. She brushes her finger against the fabric, tracing the logo delicately before sliding the thong over your hand, guiding it onto your fingers. Her eyes sparkle with delight as she watches you manipulate it into position."

Oh honey, you're really going to look stunning in that! It's absolutely perfect for you. And remember what I said about our eyes...

"Mmm, I think these thongs are made for us, sweetie," Mommy purred as she selected a Queen of Spades thong in his size. "Can you believe how perfectly these will fit your petite frame?"

She turned her attention to the matching bra with a seductive grin. "Just imagine how sexy your little nipples will look poking through this lace." Running her fingers over the delicate fabric, she glanced up at him with mischief dancing in her eyes. "It's just too bad you won't have much to fill it out," she teased gently, unable to resist poking fun at his tiny dicklette.

Catching his surprised reaction, Mommy laughed lightly, stepping closer and placing a hand on his shoulder

"Mommy thinks you have great taste," you say, cooing as you admire the thong and top yourself. "It's perfect for someone with your blue eyes." Your lips curl into a devious smirk, gazing directly into my tiny blue eyes.

My heart races at your boldness, feeling an undeniable stirring between my legs. I swallow hard, trying to find my voice amidst the lustful thoughts clouding my mind. "We-well, if you think it's a good idea..." I

Mommy: "sigh" Alright, sweetie. If you insist. But remember, these will look cute on someone who's all grown up like a man. Just something for you to think about.

"Mommy grins mischievously as she feels your excitement in the car. She knows exactly how to push your buttons, and she's not about to stop now."

*Upon arriving home, Mommy saunters into the living room, her Queen of Spades lingerie set perfectly accentuating her voluptuous curves. She picks up the remote and turns on the TV before plopping down on the couch, one leg crossed over the other, giving you an enticing view of the lacy thong that barely covers her round ass cheeks. She grabs a throw pillow, hugging it to her chest, her massive tits straining against the fabric of her skimpy top. Her eyes sparkle with amusement, anticipating your reaction to the

"Mommy's eyes twinkle with anticipation as she hears you mention taking a shower." Well, if you insist on taking a shower now, go ahead sweetie. But remember, I washed all your clothes earlier. So after your shower, you'll have to wear something clean from my wardrobe since your clothes are being dried.

"She playfully nudges you towards the bathroom, her breasts swaying enticingly close to your face.
