The Catalyst Panties

"An innocent glance leads to a new relationship dynamic between niece and uncle"

Font Size

I enter the laundry room to look for drinks and snacks. We store food here when we have limited space in the kitchen. And I grab a bottle of pop, along with a box of crackers. I turn around to head back out. But then, out of the corner of my eye, I see them.

Along with assorted pairs of jeans and other items of clothing, I see a pair of purple cotton panties. Just hanging on the line with a couple of clothespins, like it’s no big deal. I think to myself, “These aren’t my wife’s!”

No, these have to be my seventeen-year-old niece’s. Danielle visits my wife, Janet [her mom’s sister], and me for a couple of days during her spring break. Even though we live in the same city. And while she’s visiting, we have made a deal; we each do our own laundry. To avoid these exact kinds of situations. We don’t need to see her stuff, and she doesn’t need to see ours. But I guess I forgot that today is her laundry day.

I quickly glance at the laundry room door. No one is watching me! I know I shouldn’t explore my niece’s underwear, but my curiosity is winning out. I want to see them up close. I close the door, then return to the clothesline.

These sure are cute, I think to myself. I reach out to touch Danielle’s purple briefs. The soft material of her cotton panties feels so smooth against my fingers. I bring them closer, and notice there’s also lace along the edges of the gusset. So pretty! Against my better judgement, I feel myself grow in my shorts. Even though no one else is around, I grin sheepishly.

Suddenly, I hear a sound from the floor above. Followed by someone’s feet moving. Shit! It might be Danielle coming to check her laundry. I exit the laundry room in haste. And, just as I finish closing the door, I turn to find Danielle walking down the stairs.

She’s looking cute today, dressed in a sweater and skirt. And with her short stature, brown hair in a ponytail, and wearing a pair of glasses, Danielle doesn’t look like she’s almost an adult. She gives me the sweetest smile and says, “Hiya, Unky Nate. What do you have there?” She glances at the box and bottle I’m carrying. “Oh, right, I forgot you had Coke! And crackers too. Maybe I’ll have an excuse to make some soup now.”

I laugh at her innocent comment; if she only knew what I had just done. I return her smile and say, “I’ll pour you some Coke, sweetie.” And start heading up the stairs.

But then, almost as though she can read my mind, I hear her nervously say to me, “Uh… when you were in the laundry room, you didn’t see… them, did you?”

Play it cool, Nate. I turn around and ask her as innocently as I can, “What do you mean?”

That seems to be the right response, because Danielle’s smile returns, “Never mind. I’ll see you soon.” She enters the laundry room and closes the door. And I breathe a sigh of relief.

A few weeks have gone by, and it’s almost April now. The weather is improving, and Danielle still makes her weekly visits. And she’s never made it apparent that she suspected any impure thoughts on my part. For all she knows, I really was just going to the laundry room storage that day. And just missed her clothes and underwear.

And even after a couple more close calls, she still suspects nothing. But I could’ve sworn Danielle has been acting more flirty towards me lately. And more than once, I also swear she flashed me in the hallway. But maybe her recent behaviour is just in my head. After all, people bend over without intending to flash anyone all the time. It’s no big deal, right?

One day, Danielle drops by on the way home from school. She’s still wearing her school uniform. And given how often she comes over, I guess she sees me as her cool uncle. Not that I mind.

Later that evening, while I’m watching TV, Danielle joins me on the couch. She gives me a sweet smile and asks, “Whatcha watching, Unky?”

I sigh, “Absolutely nothing! Been scrolling around forever.” After a few minutes of futility, I get the sense she’s come to chat about something. And so I turn off the TV. I look at her and ask, “Do you have something on your mind, sweetie?”

Danielle nods her head and says, “Yes. Well, you know how my senior prom is coming up soon, right? At the end of April?” I smile. She’s been looking forward to going with her boyfriend for some time. She continues, “Yeah… so, I kind of need to get a prom dress.”

I nod at her with a smile and say, “Sounds like a plan. But I’m not sure I’m the right person to have this conversation with.” I laugh, “With me being a man and all… not to mention your uncle.”

She gives me a serious look and says, “No, you are exactly the person I want.” She takes a long breath, letting it out before saying, “I want you to take me shopping for prom dresses.”

I gasp in surprise and say, “W-what?! Danny Girl, you know I’d do anything for you but…” I give her an apprehensive look, “This… is pushing it. There are boundaries that uncles and nieces shouldn’t cross.” Am I being a hypocrite? I think to myself.

Danielle shrugs her shoulders and says, “Just treat this as you would when accompanying Aunty Janet when she shops for clothes or something.” She shoots me a sly grin and says, “Besides, aren’t you tired of looking at her plain undies all the time?”

I gasp at Danielle’s sudden boldness and say in a panic, “Yes… no, wait…” I shake my head and get off the couch. I then turn back to her and say with growing exasperation, “We shouldn’t even be having this conversation! Where is this coming from?!”

She shoots me a shit-eating grin and says. “Really? So you weren’t being curious in the laundry room the other week, about what I wear underneath?”

I’m getting too old for this shit! I rub my temples and groan, “We’re not doing this.” Then I try to steer the conversation elsewhere, “Anyway… why didn’t you just ask Michelle [my daughter]? She’s only a few years older than you, plus she’s a girl.”

Danielle sighs, “I would, but she’s been weird lately. She’s too…” She raises both hands to make air quotes, “Busy to chat.”

I laugh, “Yeah, that’s called being a college student. Her midterm is coming up.” I give her an empathetic smile and say, “So, there are no other girls you can get to help you? A friend, your aunt, your mom, etc.?”

Danielle sighs and rolls her eyes impatiently, “Look… I need a guy’s opinion, okay?” She then gets up in a huff and leaves the room.

I move my hand through my hair and sigh. She’s quite insistent that I help her look for prom dresses! What do I do now? Should I ask Janet to get involved?

Unfortunately, I’m unable to convince Danielle to take someone else, and it’s now the following Saturday. When I pick her up at her house, she greets me in a casual outfit of a shirt and jeans. Her hair is also down, and she isn’t wearing her glasses (maybe she’s wearing contacts?). After establishing some ground rules (i.e., don’t make any comments that might imply I’ve seen my niece’s underwear), we then drive out to the nearest prom dress store.

Upon arrival, the clerk [Tara] greets us and, upon noticing me, asks Danielle if she’s okay with me being there. Danielle tells her, “It’s okay, I insisted.”

The clerk looks at my sheepish grin before looking back at Danielle’s confident face. She then nods and says, “Well, I guess if everyone is alright with it.” She looks at me right in the eye and says, “It just might be awkward for you, Sir. I’m assuming you’re her… uncle?”

After confirming and giving my consent, Tara then asks Danielle what kind of prom dress she’s looking for. Danielle blushes and tells her, “He’s not here, but I want to surprise my boyfriend with something sultry… in red and gold. Something that says… I hope that you have built up enough stamina.”

I give my niece a surprised look. What has gotten into her lately?! She’s just full of surprises. Does she not realize or remember who else is in the room with her and the clerk?

The clerk smiles and takes us to a large room in the back. Then she leaves to go through her selection of prom dresses, leaving Danielle and me alone.

Tara returns a few minutes later with three prom dresses. Danielle looks them over and asks me for my input. I gulp when I see the plunging necklines. But I can’t pretend I’m not excited and pick a gorgeous red and gold dress. Danielle smiles at the clerk and says, “That’s the one.”

The clerk compliments her choice before telling her, “Before we proceed, are you sure you want your uncle to stay for this next part? You’re going to have to strip down.”

Danielle looks back at me, looking for confirmation. I look in her eyes, as it suddenly dawns on me. She wants me here! I give her a nod. Danielle returns to look at Tara and smiles, “Yes.”

The clerk smiles and tells my niece that she’ll need to see how the prom dress looks on her. And asks her to strip down to her bra and panties, before she leaves the room. I feel my face turn bright red. Am I really about to see my niece in only her underwear? My breathing turns shallow as I glance at Danielle.

Danielle notices my reaction and smirks. She then bends over and subtly lowers her jeans, flashing the top of her underwear. I feel my hair stand at the back of my neck. This is way too risky! But despite my worrying, I can’t help but notice she has a cute taste in underwear. What’s wrong with me?!

My niece giggles and playfully snaps her waistband, “I thought you might recognize these undies.” She gives me a wink and says, “And there’s plenty more where that came from.” And with that, Danielle unzips her jeans and lowers them to the floor.

I feel a lump in my throat. And my mouth opens and closes without making a sound. What am I supposed to say to my niece stripping in front of me?

Sensing my conflict, Danielle grins at me. She grabs the bottom of her shirt and says, “Ready, Unky Nate? Few get to see me in my underwear, and I want you to be the first family member that does.” What’s happening? And why does she want me, or any family member, to see her in her underwear?

My breath hitches in the air as I watch my niece pull off her shirt. And now, she stands before me in a matching purple bra and panties set. Her breasts, while not huge, fill out the cups. I watch as her breasts rise and fall with her breathing. And I also see beads of sweat forming on her breasts. Could she be getting excited as well?

Even if this is only for her prom dress fitting, I know I shouldn’t be seeing my niece in this way. I shouldn’t be admiring how the soft cotton material of her underwear fits snugly on her breasts and crotch. But damn, her underwear is cute. And, despite my apprehension, I feel myself grow erect in my boxers.

Danielle giggles as she playfully snaps her bra straps, “I’m glad this set meets your approval.” She then shoots me a shit-eating grin before continuing. “I’ve been trying to get your attention for a while, Unky Nate.”

My jaw just about hits the floor. Huh, why? I’m her uncle! But just before I can ask her, Tara rejoins Danielle and me.

Tara walks over to where we’re standing with a smile on her face and says, “Are you ready to try on the…?” She looks at my flushed face as I force my mouth shut. Her face changes to one of suspicion. I can’t have her suspect that my shallow breathing is because I’m excited by my niece!

Tara then looks at Danielle’s nearly naked state, as Danielle awkwardly turns away. Her face is bright red. Tara then sighs and says, “Whatever, I don’t get paid enough to deal with this.”

My heart rate returns to normal. At least for now, I’m in the clear. As quietly as possible, I breathe a sigh of relief.

After returning to her professional demeanour, Tara looks back at Danielle and says, “Well, let’s get you in your prom dress.” Danielle smiles and nods.

A minute later, Tara brings over Danielle’s prom dress and tells her with a smile, “Alright, sweetie. You are going to have to step into this dress.” Danielle nods. And for the next few minutes, I can only watch in awe as Tara assists my niece in getting into her prom dress.

My breath catches in my throat. Danielle does not know what she’s doing to me. I watch her breasts jiggle in her bra as she bends down to pull her dress up. My breathing turns shallow as I admire the sight in front of me. I smile to myself. At least Tara is too busy to notice my reactions.

Danielle then gets her dress stuck around her chest. I feel my instincts kick in as I watch my niece struggle to pull her dress up. It’s all I can do to not walk over and help her out. But I catch myself. Tara is there to help, not me.

And, right on cue, Tara giggles and says, “Hold on, dear. You are going to tear your prom dress before you even attend your prom. May I?” Danielle nods her head. I can’t see what Tara is doing, but I can only assume she’s maneuvering around my niece’s bra-clad chest. My pants feel tighter suddenly, as I feel myself react in a way that an uncle shouldn’t. Dammit, Nate! This is your niece.

And finally, Tara steps aside and smiles at me, “Well, doesn’t your niece look beautiful?”

I look at Danielle as she grins sheepishly at me. My heart is practically beating out of my chest. My niece is standing before me in a gorgeous red and gold prom dress, and looking so grown up. This is not a high school prom dress. This is something a Hollywood actress wears on the evening she accepts the award for best actress.

As my eyes move around, I feel a lump form in my throat. My eyes zero in on the deep V-neckline, exposing my niece’s breasts. I feel my cock strain uncomfortably against my underwear. I then shoot my niece a look that says, “Do you want to give your uncle a heart attack?” Danielle must be reading my mind, because her face turns bright red.

Tara then awkwardly clears her throat, breaking me out of my trance. And says, “So… uh… what do you think?”

Danielle smirks as she regains some of her earlier impulsiveness and asks, “Yeah, Unky Nate, will this accomplish what I want with my boyfriend?” I feel my face burn as I’m reminded of Danielle’s earlier comment.

I awkwardly grin at Danielle and say, “Yes, Danielle. You don’t need to worry about your boyfriend not having enough stamina.”

Danielle smiles and tells Tara, “Perfect, I’ll take it!” And as she rings us up, Tara gives me a not-so-subtle look of “I don’t want to know why an uncle needs to know about his niece’s sex life.”

It’s now late afternoon, and we’ve returned to my place after purchasing Danielle’s prom dress. Janet hasn’t returned from work yet, so Danielle takes her new dress to her room. As she does that, I call Danielle’s parents to tell them she’ll be back soon. After disconnecting, I rub my temples. And grumble under my breath, “I need a drink after that.”

I grab myself a beer from the fridge and sit down on the couch. I sigh heavily. Danielle looked so grown-up in her prom dress. But I shouldn’t have been there or known about her bedroom activities. No wonder Tara gave me the glare of death.

But despite my apprehension, I can’t deny how excited I was to see my niece in her cute underwear. My breath hitches in my throat as I feel my cock press against my boxers. I groan out loud, “Oh God!” There’s no way I could’ve dealt with this at the store, but now I am free to relieve myself.

Without thinking about the possibility of being walked in on, I move my hand to unzip my jeans. And pull my jeans down. But just before I can proceed further, I hear a knock on the wall beside me. My heart races as I turn around, fearing the inevitable.

And sure enough, Danielle’s sweet face greets me in the doorway. A lump forms in my throat. There’s no way out of this. She’s seen me with my pants down. But she smiles at me and says, “You too, huh? God, you don’t know how close I was to rub one out in the store. Even with Tara there.” She then bites her lower lip awkwardly and asks, “Could I join you?”

My heart races again. Only now it’s not just from nerves over being walked in on, but from knowing how turned on Danielle is. I know I should squash this right now; tell her this is not something an uncle and niece should do together. But my needs outweigh my brain. And I gesture for her to join me on the couch.

Danielle smiles. I then watch as she unzips her own jeans, revealing her purple cotton panties. My breath hitches in my throat. She then kicks her pants away, before sitting down on the…
