Beth and Zack had been friends since childhood. He'd been, and still was honestly, a bit of a nerd. But in the last year of high school Beth had bloomed. Going from a mousy tomboy to a buxom beauty had been a big change in her experience. But since the two were going to go to the same college and were so close, they decided to get a two bedroom apartment to share. It was cheaper and quieter than the dorms and neither would have to risk a roommate that was problematic.
The changes in Beth has caused her to be more confident and accepting of her sexuality, at least in her wardrobe choices. Being so close to Zack helped as she was able to be comfortable at home not wearing a bra or hanging out in just a t-shirt and panties. Zack definitely checked her out but was never creepy about it and they both grew accustomed to just wearing what was comfortable to them.
However they'd been careful not to have any explicit nudity around each other. Always making sure to cover up going to and from the bathroom. Keeping doors locked when showering or changing. And generally knocking before entering bedrooms and respecting each other's privacy. Which is why Zack was a bit surprised to be eating breakfast one morning when Beth exited her room wearing only a pair of panties. Not only was she topless but her nipples were adorned with two silver bars.
"Umm... Beth... what's going on?"
Beth stretched her arms out over her head and arched her back, forcing her chest and erect nipples to jut out towards him. "Well. I was out with some friends yesterday and I decided to get my nipples pierced. There were a lot of after care recommendations. One is to avoid tight clothing and basically to let them breathe. So, that's what I'm doing. I figured you wouldn't mind since we're always a bit casual around here."
Zack snorted a bit. "Do I mind if my incredibly hot friend walks around half naked? No, not particularly. But it is new. And it's going to make it difficult not to ogle you a bit. Sorry in advance."
"Don't be sorry. I think it's fair that if I'm leaving some part of my body uncovered that's an invitation for you to look. Besides, I think I have great tits and nipples, so if you weren't at least checking them out a little I'd be almost offended." She smirked playfully at him, reaching up to cup her chest suggestively to tease him, her fingers rubbing her nipples softly.
"Fair enough. So besides teasing me mercilessly, what's on your agenda for today?"
She pouted at his lack of reaction and dropped her hands. "Well I was going to go out on our balcony to tan a bit. Want to join me?"
He agreed then went to his room to change. Coming out in just a pair of shorts he stopped short. Beth was laying one one of the two lounge chairs, still wearing only the tiny panties. Both her hands massaged suntan lotion into her chest, which was glistening already. She quickly circled her nipples to cover them before moving down to start rubbing it into her stomach.
"You know, I always thought it was unfair that guys can just walk around topless but girls can't. Seems pretty unfair." She leaned forward to coat her legs, her arms pushing her boobs together as she looked up mischievously at him, inviting him to admire her charms.
He just smirked, maintaining eye contact and not letting her distract him with her new casual approach to nudity. "I mean, in some states and cities you can. This isn't one of them but since it's just the two of us I'll let it slide. In fact, I want you to be as comfortable as you want around here so wear or don't wear whatever you want." He put some lotion on his hands and quickly covered his front.
An almost feral grin adorned her face. "Oh yeah? Maybe I'll take you up on that." Her fingers slid under the waistband of her panties briefly, pushing them down just slightly before she gave him a saucy wink and turned over onto her stomach. "But not today at least. Do you mind doing my back?"
He groaned slightly, moving over coat the back of her legs before straddling her butt and rubbing lotion into her back. She purred as his fingers massaged her back but he didn't take any liberties with the opportunity.
"Thanks. Now lay down and let me do your back."
He nodded, lying face down. She straddled the upper part of his legs instead of her bottom like he did. Being so much taller than her, this forced her to lean forward dragging her chest and nipples over the small of his back multiple times as she covered him.
"You're such a tease Beth. You're lucky I'm a nice guy."
"You are a nice guy, which is why I trust you to let me explore my body and sexuality as I want it without doing anything without my consent. I'm still getting used to having a body people might want to see and feeling comfortable in it. And as a nice guy, I could use a favor. I want to get my clit pierced but it feels weird to just have my pussy out with a strange man. So I was hoping you could come with me for support?"
He sat up slightly and looked back at her. "You want me to go with you to get your clit pierced? You know that means I'll be seeing everything right? You sure you're ok with that? It's a big step."
"Well. The aftercare is similar anyways and you already said I should be comfortable around here. So I was planning on being much more casually nude anyways. It makes me feel sexy and empowered."
"I still think you're just a tease. But alright. Let's do it."
After tanning for an hour or so they both showered. She came out wearing a loose dress. Even so the swaying of her chest and the two slight indentations indicated she hadn't worn a bra. The two traveled to the piercing studio and walked in. Ironically, the piercer was a woman who directed them to a private room and asked her to lift up her dress so she could work. Beth gave Zack a sultry look before grabbing the bottom of her dress, lifting it over her head, and handing it to him. She was bare underneath. She then sat in the chair, scooted her butt forward a little, and draped her legs over either arm completely exposing herself to them. The woman just smiled and shook her head before putting on gloves, pulling out her tools, and after asking a few questions about what Beth wanted piercing her clit. Beth sat there spread eagle and bare facing Zack and essentially daring him to look at her body until the woman finished her instructions and stepped out.
"Still think I'm a tease?" She ran her finger over her clit and the new piercing softly, shivering with excitement. "It feels great, how does it look?"
He laughed, standing up. "You know you're a bombshell and the piercings and sudden confidence about casual nudity just add to it. Now get dressed so we can go home. I'm going to have to rub one out thanks to you." He then playfully tossed her dress to her.
She caught it and stood up, shaking it out slowly to extend her exposure for a few more moments before sliding it on. "You heard her, I can't touch myself for a couple of weeks until these heal. Now who is the tease?"
The next several weeks as she healed saw her take full advantage of his earlier offer. She would retreat to her room upon coming home, strip out of her clothing, and then hang out with him just like they had before. The only difference now was she was always completely naked and constantly teased him by leaving her legs spread apart or finding innocent ways to rub her tits against him as they shared spaces.
That is until one morning when he left his room and heard the shower running but the door to the bathroom was ajar slightly. Hearing what sounded like crying he moved to the door, opening it and looking in, only to realize it wasn't crying but moaning. There was his friend since childhood with one leg up on the side of the tub, eyes closed, as one hand worked on her clit the other directed the pulsating detachable shower head at her pussy. Her breathing grew more haggard over the next few minutes before her back arched and she cried out in pleasure. Shocked, he quietly put the door back the way he found it before escaping to class.
After class he walked in to the sound of moaning again. Walking to his room he paused at her door. It had been left wide open. On her bed she was spread wide, humping a rabbit vibrator while her other hand played with one of her nipples. He stood there mesmerized for a few minutes before suddenly her eyes opened and looked right at him. Instead of being surprised she simply smiled and bit her lip, before her eyes half closed again, her toes curled, her back arched, and she came hard. After a few minutes of panting she again looked over to him. "Thanks. That was really hot. I always wanted someone to walk in on me touching myself like a bad little girl."
"Well, actually, I saw you earlier today too in the shower. Is this a new open door policy?"
"Is that a problem? I just feel empowered to explore my sexuality with you. I've always enjoyed reading CMNF or OON stories. Always fantasized about all eyes drinking in every private part I normally hide from the world. And now that I have a body I love, I just want to keep it bare as much as I can. Like I said it feels empowering to embrace my femininity and be comfortable in my skin. Thank you for that."
