-----------------©®©®©®©-----------------
It was supposed to be a quick Target run. You and Peter had a list-snacks, detergent, some new pens because Peter always lost his, and maybe a new hoodie for you because, despite having a dozen, you still steal his. But shopping with Peter was never quick.
"Okay, we need to focus," you announced, gripping the red shopping cart handle as you stepped through the sliding glass doors. "No distractions, no unnecessary items, no-"
"Oh my god, look! Lego sets are on sale!" Peter pointed excitedly, already veering off-course.
You sighed, but your lips twitched in amusement. "Peter, focus."
"But-"
"Snacks first. Then you can check the Legos."
Peter pouted but let you guide him toward the grocery section, where you picked out chips, popcorn, and his favorite gummy worms. The trip continued with him sneaking in random items "Babe, do we need a mini waffle maker?" "Peter, we don't even make waffles." "But we could!" and before you knew it, you found yourself near the clothing section.
And then you saw it. The underwear aisle.
A mischievous grin spread across your face. Recently, you had seen a TikTok prank where girls grabbed too big size bras to see if their boyfriends would notice. Peter was observant-sometimes painfully so. If you tried this prank on him, would he pass?
You casually wandered into the underwear section.
Peter, pushing the cart behind you, raised a brow. "Uh, babe? Do you actually need undergarments?"
You hummed nonchalantly, pretending to browse. "Maybe. Just looking."
Peter didn't argue, just trailed after you, rocking back and forth on his heels. You grabbed two bras-two sizes bigger than your usual size-and plopped them into the cart.
Peter blinked at them. His head tilted. Then his brows furrowed.
"Babe," he said slowly, picking one up, "are you sure this is your size?"
You feigned innocence. "What do you mean? I know my size."
Peter's nose scrunched in confusion. "These seem... way bigger than your size." He turned the bra in his hands, inspecting it like it was a complex physics equation. Then he flipped the tag and saw the size. His eyes widened slightly. "Yup. These are two sizes bigger."
You bit the inside of your cheek, fighting a smirk. "What?"
"Yeah... how do you not notice that?" His head tilted even further, curls bouncing slightly.
"What do you know anything about bra sizes?" You shot back, crossing your arms.
Peter looked at you like you just asked him why the sun was hot. "We've been together for five years. Of course, I know your size."
You blinked. "Wait. What?"
Peter lifted the bra again. "These are way too big for you." Then, without an ounce of hesitation, he added, "Even if I didn't know your exact size, I can tell these are too big because I play with your boobs all the time."
Your mouth dropped open. "Peter Benjamin Parker!"
Peter blinked at you, completely unfazed. "What?"
"So, you're saying my boobs are small?"
His jaw practically unhinged. "I NEVER SAID THAT."
"You just did!" You pointed an accusing finger at him, trying not to laugh.
"Oh my god, babe." Peter groaned, running a hand down his face, already spiraling into full panic mode. "Big or small, it doesn't matter! You're perfect! Your boobs are perfect! Perfect grab size for me! I love them, okay?"
And you lost it. A full, belly-aching laugh burst from your lips as you tried-and failed-to contain yourself. Peter stared at you in distress.
"Why are you laughing!?" He whined, his voice slightly higher than usual.
You gasped for air. "Oh my god, babe-"
"Now, why do I feel like this was a trap?"
"Because it was," you admitted, still giggling. "You passed, though."
Peter groaned again, rubbing his hands over his face. "I swear, you're gonna give me a heart attack one day."
You grinned, leaning against the cart.
"Do you really need bras?"
"Not really," you admitted with a playful shrug. Then, lowering your voice, you added, "But if you're buying, I'm not gonna say no." You gave him a smirky, innocent look.
Peter exhaled through his nose, shook his head, and put the wrong-sized bras back on the hanger. As he did, something caught his eye-a black lace bra with matching lace underwear.
He checked the size.
Nodded to himself.
Grabbed the set.
Then, without a single word, he dropped it into the cart and started walking away.
Your eyes widened. "Peter!"
"Hey, wait for meeee!" You rushed after him, heart pounding.
-----------
After checking out (Peter very casually scanning the lingerie while avoiding eye contact with the cashier), you arrived home and started unpacking the bags. You were about to put the new lingerie set away when you felt Peter's arms wrap around your waist from behind.
"You gonna try it on?" His voice was low, teasing.
You bit your lip. "Why? You picked it out. Shouldn't you already know how it would look on me?"
Peter hummed, lips grazing your neck. "I have a pretty good imagination, but, y'know... I like proof."
You turned in his arms, grinning up at him. "You're impossible."
Peter grinned back. "And yet, you love me."
You rolled your eyes, but your smile softened. "Yeah, yeah."
He pulled you closer, pressing a lingering kiss to your lips. "No more pranks?"
You smirked. "I make no promises."
Peter groaned. "I need to start setting up traps for you."
"You wouldn't dare."
He leaned in again, lips brushing yours. "Babe, I'm Spider-Man. I know how to set traps."
Your breath hitched, but before you could respond, he spun away, grabbing the bag of snacks and heading for the kitchen.
You blinked. "DID YOU JUST FLIRT AND RUN?"
Peter laughed from the other room. "Consider it payback!"
