Kristi walked into the apartment and set the box she was carrying on the stack of three other boxes that had also been hauled in by her. She wiped her brow with the back of her wrist and exhaled loudly.
"Done!" she yelled down the hall to her brother, who was in the bedroom unpacking some other boxes. She stepped over to the kitchen counter and took a swig from her water bottle that had been sitting there.
It had been a long day helping her brother Matt move into his new apartment, but now all of the hard work was done. They had spent all morning emptying out the small moving van he had rented for the occasion. Kristi looked around the living area of her brother's apartment and took stock of everything. The living room furniture had been delivered by movers earlier in the week, leaving them to deal with Matt's boxed belongings. The living room wasn't in too much disarray, just a few stacks of brown cardboard boxes that needed unpacking and putting away.
She walked down the short hallway that was on her left, which ended in a "T". On the left side of the hall was the doorway into the one bathroom and on the right, the one bedroom. She walked into the bedroom as Matt was putting some clothes away in the closet.
"Hey, Kris. Thanks so much for helping out today. You definitely earned your pizza and beer," he said and smiled at her.
"Gee, thanks, dummy. Appreciate it." Kristi said as she flopped onto a clear spot of Matt's bed and took out her phone.
Matt apprised his sister as she laid on her stomach, swiping her phone screen. His eyes moved up her bare legs as she kicked her feet back and forth in the air, stopping to linger on her butt, which was covered by her blue workout shorts. The vee cut in on the side of the shorts revealed more of her thigh to him. As she moved her legs back and forth, flexing her hamstrings, he could see the hemline of her panties beneath the fabric.
Continuing up her body, his eyes traced her back, covered by her white tank top, and then dipped to her small cleavage. She was letting the built-in bra of the tank top do the work of a real bra today, and he could see the beginnings of her areola on her right breast. He almost got caught staring at his sister's chest before his eyes darted to the side as Kristi looked up at him.
Matt had always been in love with his sister. When they were kids, he thought she was the cutest girl on their entire block. As teenagers, he loved watching her body develop, growing into her slender, athletic frame, and pert B cup tits. She had beautiful shoulder length brunette hair and a girlish face. When they lived together with their parents, Matt was always trying to find new ways to sneak glimpses at his sister's body. His favorite used to be silently peeking in on her while she showered in their shared bathroom. But, one time, he came too close to getting caught as she had suddenly pulled back the shower curtain, and decided to give that up.
Now, he couldn't help but admire how sexy Kristi had become as she became a young woman. He longed to see her naked, to explore every crevice of her body. He wanted to touch her skin, feel her most sensitive areas. He knew it was wrong to have these thoughts, but his mind always seemed to go there. He had even compared the girls he had dated and had sex with in the past, imagining that it was Kristi he was touching and fucking.
Kristi, for her part, adored her big brother and all the attention he always gave her. He made her feel so special and like the prettiest girl around, even though she knew she wasn't. Matt would tell her she was prettier than some of the girls he had dated. She never believed him, because then why would he be dating them? But it still warmed her heart when he did pay her these compliments. She also appreciated the effect she seemed to have on her brother. She would catch him stealing glances at her, checking out her ass or trying to look down her shirt, or just staring at her face. She suspected that he used to try and spy on her in the bathroom when they were teenagers, too, but had never been able to catch him in the act.
Now grown up and Matt's body had filled out and become toned. He had dark brown hair, always kept neatly trimmed and combed. Kristi couldn't help but notice the effect that all of his attention and his attractiveness had on her now that they were both grown. Last time he had given her one of his famous bear hugs and told her how pretty she was, she felt that compliment go straight to her pussy, moistening to the point of needing to go change her underwear. She loved the feeling and the rush of it, but was concerned with taking those feelings too far. Matt was sure to notice if she allowed her body to get that turned on by him. He seemed to notice everything else as it was.
Even with her reservations, she had curiosities about her brother. Mainly, she wanted to know what his dick looked like. She had noticed him getting hard at different times both growing up and now that they were adults. It looked like he might be well endowed, but she kind of wanted to know for certain. All of the guys she had been with in her life had been pretty average in that department. Maybe Matt was different?
Matt took the last items out of the box he had been working on and put them in the closet. Then he broke down the box and pitched the flattened cardboard into the hallway, clearing a spot on his bed. He sat down next to his sister and started looking at his phone, too.
"Whew, what a day! Didn't help that it was so warm out today, too," he said.
"No kidding! I think every inch of my body was sweating at one point. I definitely have some under boob sweat marks today!" Kristi laughed.
"What boobs?" Nate joked and nudged his sister with his elbow.
"Fuck you, pencil dick!" Kristi replied and slapped her brother's leg with her left hand.
Nate laughed hysterically at this. "Oh yeah? And how would YOU know?"
Kristi eyed him, glancing briefly at the crotch of his shorts, and then back up at his eyes. Matt responded to that with raised eyebrows. Could this be her chance to confirm her suspicions about his size? "I dunno, it just seems like you'd have a pencil dick."
"Well, you couldn't be more wrong!"
"Yeah? Prove it then!" She quickly slapped her free hand over her mouth. She couldn't believe she had just said that out loud to her own brother. She had just asked him to show her his dick!
Matt paused just a moment from their banter. "Seriously?" His eyebrows raised up even farther as he waited a beat for his sister to respond. When she didn't, and kept her hand planted over her gaping mouth, he followed that up. "Well, I'll show you mine if you show me yours."
Matt waited with heightened anticipation for his sister's response, wondering if he had taken his want to see her naked too far. She could easily call him a perv and shut the door on this ever taking place.
Kristi dropped her hand from her face. She needed to play this very carefully. "What, are we seven years old again or something? Geez, Matty!" she said as she poked him on the side of his leg.
Matt's brain flashed back to the time in their early childhood when they had actually played the "I'll show you mine if you show me yours" game. Kristi was just seven years old and Matt, being 18 months older than her, was eight and a half years old. They had been playing hide and seek with friends and had hid together in a walk-in closet. After a while, and not having been found, they got bored and had been chatting. Kristi had brought up the idea and Matt had instantly agreed, both of them pulling their pants and underwear down to reveal their prepubescent genitals to one another.
Ever since that day, Matt had been enamored with his sister's body and wanted to see more. Despite his pleas over the years, Kristi had never agreed to play that game again. The closest he had ever gotten her was after they had both hit puberty and agreed to show each other their pubic hair. But even with that, he didn't get to see anything below the top of her underwear line.
Back on the bed, Matt's heart was racing, and his cock had started to harden in his shorts.
"I mean, you asked me to prove I'm not a pencil dick, and I'll bet you wanna prove you have boobs," he egged her on.
Kristi sat up on the bed, criss-crossing her legs under her, and stared at her brother, noticing the tenting taking place in his shorts.
"I DO have boobs," she sneered playfully at him. "So let me get this straight. You'll show me your pencil dick and I'll show you my boobs? Okay, bet," she said as she extended her hand for him to shake.
"Ohhh, no, no, no, Kris," Matt shook his head. "If I'm showing you my package, I want to see all of your goods. Boobs, pussy, ass. All of it."
Kristi kept staring at him, but had pulled her hand back a bit. As she thought it over, she could feel her pussy heat up and moisten. "Okay. Fine. Full monty it is. But I want to see all of you, too. A fully nude for fully nude exchange."
Matt reached out and shook her hand so fast it almost knocked her over. "Deal."
Kristi sat there in a state of shock for a moment before she uncrossed her legs and stood on the floor next to the bed. "Okay, macho man. Let's do this."
Matt practically jumped for joy. He stood next to the bed, facing his sister. His erection was noticeable, stretching his loose-fitting shorts and pointing in Kristi's direction. He couldn't believe this was about to happen. He was going to get to see his dear, sexy, sister naked!
"You go first," Kristi prompted. Matt removed his sweat-soaked shirt and threw it across the room.
"Your turn, sis," he said eagerly.
Kristi eyed her brother's toned chest and small nipples while she grabbed the hem of her tank top with both hands and slowly peeled it up, pausing just before her boobs were to be revealed. She took a deep breath and closed her eyes, then yanked it the rest of the way off.
Her boobs jiggled a little as they released from the tank top's built-in support and Kristi moved to toss the top on the bed. She instinctively reached up and cupped both of her breasts in her hands, rubbing them in the cool air. It felt nice to be out of the sweaty top.
Matt stood and stared at his sister, his mouth slightly agape, as he watched Kristi rub her breasts. When she released them from her hands, he could see she had firm, perky boobs with silver dollar-sized areolas and cute, tiny nipples in the center. They were absolutely beautiful and probably the best pair of tits he had ever seen in his life. Unconsciously, he licked his lips as he stared.
"Earth to Matt!" Kristi said as she snapped a finger in front of his face. "C'mon. Your turn. Time for the big reveal!" she said and smiled. She could feel a rush of warmth in her crotch as she anticipated getting to see Matt's cock for the first time in their adult life.
