There is usually nothing more enticing for Zach than to see his sister standing at the corner in a night shirt that does almost nothing to hide her assets. That is until he sees her this morning. Every morning since they moved in together Margo has become a different person. Never would she go around wearing a barely fitting night shirt back home at their parent’s house. Of course Zach isn’t complaining. He has always had a thing for his sister.

They moved in together to share the expenses of living on their own. It was actually Margo that suggested it. She is a few years older than him, and has been living on her own since she moved out of the house. She has had roommates to help with the expenses, but when her last one moved out she asked Zach if he would like to move in. Zach jumped at the idea because he had no plans to go to college, opting to go out looking for a job that might launch him into a career instead. He certainly didn’t want to stay at home and be forced to follow his parent’s stupid rules when he is an adult. So he jumped at the opportunity.

Now as long as he has known his sister, she has never been one to dress or act the way she has since he moved in. Even on her own, with roommates, all girls of course, she would still dress normally, hiding everything. And since she has always been this way he has had to resort to other ways of catches glimpse of her—usually when she’s in the shower, changing to go swimming in the pool, or some other random occasion where the opportunity to get naked arose. Now, those times after they moved in together and she began dressing differently he had gotten excited. Staring was an issue that he had to overcome. It wasn’t easy, but he did it and luckily he was never caught doing so.

Now, not being able to stop staring at her is a new problem. This morning is different. This morning Margo looks incredibly different. Zach is sitting in his usual spot at the table having sat down without really looking at her. He just climbed out of bed and stumbled into the kitchen after smelling the coffee brewing. Normally coffee could wait a little bit until after his usual morning masturbation, but this morning it smelled different. The aroma was like nothing he ever has the pleasure of smelling. It is exotic and almost otherworldly. Now maybe otherworldly is a little strong of a word to use, but Zach considers himself a bit of a coffee connoisseur. He gets it from his father. His father isn’t one, nor does he consider himself one like Zach, but he likes coffee. Their father is always on the hunt for a different flavor, ordering from other countries just to get to try something new and different. His father calls it chasing the bean. That sounds silly, even to Zach who has begun doing just that. But the name stuck and they have been using it ever since.

So there he is, sitting at the table with sleep still resting at the edges of his eyes when Margo asks again, “Do you want some coffee?”

He looks up and mumbles his answer yes. Before his eyes can drop back down he has to do a double take. His hands go to his eyes, rubbing the sleep away from them and blinking several times just to make sure that he is seeing things right. Of course his first thought is that he is dreaming. He has never missed morning masturbation since his cock got hard for the first time. Ever since that day, it has become a routine that has never been broken. Even when he had a girlfriend over or he stayed over a girlfriend’s house, the first thing he did was masturbate. Some girls thought it was weird while others liked it and enjoyed the show. Some weren’t offended or could care less one way or the other, and offered to fuck him instead of him using his hand. Each and every time, he turned them down. It was his routine, and it was not something he would break easily. So it had to be a dream. He had no reason to break it this morning, and the coffee certainly didn’t do it. It smells otherworldly, but that couldn’t be the reason.

Margo swings around with a mug of coffee in her hand, her breasts jiggling back and forth beneath her shirt. Zach’s eyes go right for her chest. And practice he has in not staring or making it obvious that he is looking goes right out the window. If not for her new look his eyes would probably never leave her chest. “Earth to Zach,” she says, lifting the mug in the air. “You look like shit, want some coffee?”

“Yeah ... um ... sure...” he mumbles. “What ... uh... ?”

“Good,” she says, setting the mug on the table in front of him before spinning back around toward the counter. She bends over it, her night shirt lifting up over her ass, showing everything off, including her new assets.

Margo normally has a wide mouth with pouty lips, the kind that every man or woman dream of kissing. Her normally long dark hair is pulled back into a pony tail. Her beauty is undeniable, always catching the attention of men and women wherever she went. Most of the time it was men wishing they could have her—the same for many women—and a lot of the times women wishing they could look like her. This morning she is nothing like that and even more than that.

Bent over like she is, Zach gets to see her pussy glistening right at him. She isn’t wearing panties, she never does. At least she did until he moved in. There is a light coating of fur covering her snatch, as well as the backs of her thighs and ass. Sitting atop that nicely shaped backside is a short little tail. As he sits and stares, he can swear that she wiggles her ass a little for him before finally standing up and turning around with a cup of coffee of her own. She saunters over to the table once again and sits down facing her brother.

He looks at her as she smiles at him. Margo is more beautiful than before. Normally a statement like that would never enter his brain because he didn’t think it were possible. By this morning, she is. He pinches himself. “Ow!”

“What the hell is wrong with you?” she asks, taking a sip from the mug.

“I was making sure that I wasn’t dreaming,” he says, his eyes glued to the pointed ears atop her head.

“You’re not dreaming silly,” she says, still smiling at him.

Zach wants to look away, if only to look back to find her unchanged. But he finds it nearly impossible to not keep looking at her. She is covered in a bluish fur that seems to only enhance her beauty. “Are you sure it isn’t a dream?” he asks, feeling that if it were a dream then she would answer that it is and then he would know for sure that he was indeed dreaming.

“It’s not a dream,” she answers. “Does it feel like you’re dreaming?”

“No,” he says blushing.

“Do you like what you see?” she purrs.

“You’re beautiful,” he says.

“If you weren’t my brother, I would say something sarcastic like, there’s an original pick up line,” she says with a giggle.

“Well, it’s true,” he says.

“So was I ugly yesterday?” she asks.

“You were then, but you’re even more so now,” he replies, swallowing hard, not sure where this is going. Zach sort of feels like he is being set up for something.

“I didn’t expect this from the coffee, but it happened,” she says with a shrug. “If anything, it is the perfect icebreaker between the two of us.”

“The coffee?” he asks, looking down at his mug and breaking his gaze for the first time. She nods. “I’m not sure what to say.”

“About the coffee or the icebreaker?” she asks.

“Both?” he responds.

“Well, the coffee comes from some village on a remote island somewhere off the coast of...” she bites her bottom lip and rolls her eyes to the ceiling briefly. “You know, I don’t remember where. I got it off some site that I can’t seem to find anymore. Anyway, it comes from some tribe that has been hidden away for a long time and only recently discovered.”

“And the ice breaker?” he prompts.

“That...” she says, letting the word hang for a moment. “You obviously want to fuck me.”

Zach is instantly flabbergasted. “You’re kidding me, right?”

“No,” she says. “Just look at how you’ve been watching me this morning with your tongue practically hanging out.”

“That’s ... that’s because you look like a cat!” she shouts, trying to deny the obvious. And why am I trying to deny it?

“Zachery, my dear brother, I know you’ve been watching me, catching me every chance you could when I got naked,” she accuses him.

“You know that?” he asks in almost disbelief. She smiles in response. “How the fuck did you know?” he asks what he thought as a dumb question and wishes he could withdraw it before it hit her ears. Being young and dumb, as the old saying goes, he knows he had to have been reckless more than once. But then that would mean that since she knew it was happening, she didn’t care or wanted it to keep happening.

“Of course I know it,” she answers. “At first I thought you were a little shit for trying to sneak around and catch a peek. But the more I thought about it, and the more you grew, I got to liking it.”

“Why didn’t you say anything or tell mom and dad?” he asks more out of curiosity than anything else.

“Because I didn’t want to upset the balance in the house,” she answers. “We have such a great relationship with our parents that something like that would have fucked it all up.”

“Oh...” is all he can find the words to say.

“Besides, as time went on it was kind of kinky,” she continues. “I used to play with myself, hoping that you were watching.” The last part sounds like a question, as if she wants some kind of verification.

Instead, Zach jumps into another question. “Is that why you’ve been dressing and acting the way you have been?”

She nods. “I kept form being sexy at home because well, you know how mom and dad are. But I also didn’t want my roommates to find me attractive. I wanted to save myself for you, but you little shit, never made a move on me.” Zach wants to respond, but he hasn’t a clue of what to say. She gets up suddenly and takes the seat right next to him. “What is it with men?” she asks with a puff.

“What do you mean?” the boy asks, finding his voice again.

“You guys are always horny and shit, but you never initiate anything,” she says frowning. “I mean how hard is it to just walk up to a girl and say, ‘Hey, let’s fuck’?”

“It’s pretty hard when it’s my sister I’m asking,” he sputters out.

“Yeah, I guess so,” she agrees. “But I have been dropping all kinds of hints.”

“Is that why you got the coffee?” he asks, trying to sound casual still even though his sister is practically throwing herself at him now. Maybe it’s the curiosity of finding out why she is the way she is now. Maybe it’s something else, like he is scared to go that extra step toward something that he has wanted to do for the longest time.

“It wasn’t intentional, I’ll say that,” she says. “I got the coffee because it was guaranteed to pull the most reluctant to the table.”

“I’m not sure I follow,” Zach says.

“I wasn’t sure either,” she says, sounding excited. “So I asked and the answer surprised me, so I asked some more questions. I sort of said how you have a routine of jacking off every morning and...”

“You what?” he asks, anger beginning to boil up inside him.

Unfazed, Margo says, “I know what you do every morning.”

“How?” he asks, his anger settling a little—this is his sister after all, the same one that is throwing herself at him.

“You’re not the only one that can spy,” she says with a grin. “Plus, I was friend with half your girlfriends or friends of their sister or brothers.”

“I can’t believe they told you.”

“Believe it,” she retorts. “Anyway, I was told this would drag your lazy ass out of bed and that you’d forgo your morning jerk. Did it work?” He nods. “What I didn’t expect was what happened after I had my first cup. I was afraid you’d go freak out and everything.”

“Well, I don’t know about freaking out,” he says. “I mean, it was a shock to see you like this, but maybe it was because I was still tired.”

“Maybe,” she agrees, clutching his hand and abruptly asking, “So, are you going to fuck me or not?”

So part of him wants to scream that he does, but instead of saying yes, he says, “What?” He knows exactly what she said. It has actually been a question he has been waiting to hear for years. He is feeling disbelief at the moment, never truly expecting to ever hear such words come out of her mouth toward him. Maybe he wants reassurance, and maybe he wants to make sure that it is something she wants. After all, if it’s the coffee that has changed her physically, then maybe it had the same effects emotionally or mentally too. And to be honest, her stunning beauty is just a bit intimidating to him. While he has had plenty of good-looking girls, he is a little afraid of not satisfying her needs.

“I’m sorry,” she says quickly. “My appearance must already be overwhelming. I didn’t take that into consideration. I’ve never acted on impulse, you know that. But I’ve just got tired of wanting you and you never taking the step to try anything. I just had this impulse to fuck you, to see why all those girls find you so enjoyable.”

Zach is looking down into her night shirt which has dipped open when she leaned forward. He can see her smallish, firm breasts dangling free, as free as her twat. And if she caught him years ago spying on her, he knows she has already caught his looking at her now.

Margo gets to her feet and takes his hand, pulling him from the table. As she leads him to her bedroom, he thinks about all the wasted time because he didn’t make the first move when he first thought that she was flirting with him. She doesn’t let go of his hand until they reach her bedroom. He wonders if they could have gotten away with it in their parent’s house. They seemed to know anytime either one had a someone over. It got to the point where they both stopped trying to seek someone in or out through the window and just brought them in through the front door. Their parents could care less if they were fucking so long as they used protection. And speaking of protection...

“You’ve got protection, right?” he asks.

“Of course I do,” she answers, stepping into her bedroom. “But we’re not going to need them.”

“We’re not?” he asks.

She shakes her head. “I’m about to fuck my brother, so we’re going to do this properly.”

“We are?” he asks.

She nods. “I want to feel it all, especially since I look like this.”

“I don’t understand,” he says, looking at her with curiosity.

She answers him like a teacher would a student or a parent a child. “Everything feels so enhanced like this. I didn’t expect this to happen, so I have no idea how long it’s going to last.”
