Joe, a third-year university student studying pre-law, was at home loading up his car with bags of clothes and other belongings, getting ready to head back to the university. His little sister Britt, a freshman at the same university, ran out with one last bag. 

“I think that’s finally everything,” Britt said as she handed the bag over to her brother before turning and running back towards the doorway.

“Jesus Christ, Britt, what is in this bag? It’s vibrating,” Joe exclaimed.

“Oh, shit, it’s nothing,” Britt said, turning back towards Joe with a knowing and worried expression.

But before Britt could stop him, Joe pulled the zipper open, and sitting right there on top of some lingerie and other bedroom toys was a vibrating dildo. Joe dropped the bag from his hands, threw his arms up, and stepped back.

“Okay, I sure didn’t expect that,” Joe said, turning to Britt, who was now standing beside him, flushed red in the face.

“Um…so… Yeah, sorry about that. I guess the button was pushed when you dropped the bag in the trunk,” Britt said embarrassingly.

“Uh, okay, well, turn it off and close the bag. Mom and Dad are coming out any moment, and you don’t want them seeing that thing, those things,” Joe warned.

Joe couldn’t have been better with his timing; just as he was saying that, their mom and dad were walking down the path from the front door to the car.

“Are we all packed?” asked Dad.

“Yup, sure are,” Joe said as he closed the trunk.

“Okay, you two, have a nice trip and call us as soon as you get to the apartment,” Mom said with a smile and a hug for both kids.

“Okay, I promise,” Britt replied.

Normally, the university requires all first-year students to live in one of the residence halls on campus, but exceptions are made for siblings, as long as one sibling has completed their first year. They are permitted to cohabitate off campus if they choose.

Hugs, kisses, and goodbyes were done and said all around. Joe and Britt hopped in the car and headed out. At the end of the street, Joe broke the silence. “So, about that bag of yours?”

“Yeah, what about it? It’s just my toy collection.”

“Toy collection, like, fuck, wait, there’s more than that thing in there?” Joe asked without really wanting to ask or really wanting to know the answer.

“Of course there’s more than one toy in there. A girl’s got needs.”

“Wait, you do remember we are living together, and that means I’m going to be hearing you play with your toys?”

“Well, maybe, if you’re listening,” Britt said, laughing. “It’s not like I haven’t heard you before. You, in your room with some porno playing on your laptop, and there is that distinctive sound of you beating your meat with a load of lube. Yeah, I can hear it right through the walls, there, bro.”

“Fuck me, you can hear me‽”

“Yep, and I can hear when you climax and the moans and grunts you make. I also know that lately you've been into step-sister and step-mom porn.”

Joe, now the one with the flushed face, tried to explain that it was the algorithms the website uses that populate the recommended feed. He quickly realized it wasn’t working and his sister was smarter than that.

“Okay, yeah, I look at step-sister, step-mom porn, and jack off. But, you don’t have to sit there and listen to me like that,” Joe scolded his sister.

"Well, at least when I cum, I try to make it quiet or wait ‘til I’m home alone," Britt retorted with a scoff.

The siblings sat quietly for a while before Joe broke the silence again. This time with a laugh, “So, you know all about my porn habits. What about yours?” 

“Well, if you must know, it’s actually the same. That’s how I know what you’re watching; we actually like a lot of the same pornos,” Britt confessed.

“Interesting…” Joe said.

“No, no, don’t get any strange ideas there, bro; we are not step-siblings, we are actual siblings,” retorted Britt.

“Oh of course not. It’s not like I was thinking about you and me sleeping together or doing some weird brother-sister masturbation session. That’s just plain crazy.”

“Okay, good, just so we’re clear…” Britt stated.

“I just meant that it’s interesting in that we are siblings and find out that we have similar interests in porn. I wonder if that is genetic or a product of today’s porn industry pushing that genre through the algorithms?” Joe mused.

"Joe, that's... a take," Britt said, with a slight laugh. "I'm not sure I've ever considered the genetic component of porn preferences before. I mean, we share a lot of DNA, but I don't think there's a 'likes a certain kink' gene."

She paused, then continued, "But you're onto something with the algorithms. Think about how much of what we see online is curated for us. If a certain genre is popular, or if you watch something even once, those algorithms are going to push more of it your way. It's less about some shared, innate preference and more about how the content is delivered."

"So, you're saying we're both just victims of the algorithm?" Joe asked, a playful smirk on his face. "Because honestly, that's a much less disturbing thought than a shared porn gene."

Britt rolled her eyes. "Exactly! It's less 'oops, we have the same weird genetic predisposition' and more 'the internet knows what's popular and feeds it to everyone.' Plus, let's be real, some genres are just universally appealing, right?"

"Good point," Joe conceded, shaking his head. "Though it does make me wonder if we're all just watching the same five videos because the algorithms decided we should."

"Probably," Britt laughed. "Now, can we please talk about something else? Like, literally anything else?"

“Well, maybe one of could use this as a research paper for our Master’s program,” laughed Joe.

The rest of the car ride to campus was uneventful; the siblings engaged in conversation about university life and the need to make time for friends and oneself. Joe even halfheartedly attempted to advise Britt on avoiding the university Greek life. Although Joe knew Britt would definitely be taking full advantage of the fraternity and sorority parties. Britt loved to party during high school, and she certainly didn’t change over the summer.

Over the next few weeks, Joe and Britt settled into their respective routines, which consisted of going to class, hitting the gym, and making time for studying. Joe reconnected with his friends, and Britt made new friends and reconnected with a couple of high school classmates. Britt found living in the off-campus apartment so much better than what she had been told by her friends that live on campus.

One day Britt decided to go swimming in the apartment pool. Her afternoon class had been cancelled, so it was perfect. She grabbed a bikini and slipped on the bottoms and immediately noticed she needed to shave downstairs. She pulled off the bottoms and went to the bathroom for a shave. 

After she finished shaving her pussy, she stood there looking at herself in the mirror, admiring how good of a job she did. She petted herself, feeling just how smooth it felt. She knew instantly she needed to make an appointment for a wax job soon.

She walked out of the bathroom, heading back to her room, when Joe stepped out of his room. “Jesus Christ, Britt, why are you walking around here naked?” exclaimed Joe.

Britt tried covering herself the best she could with her hands, but it was too late; Joe had already seen most everything. Britt, having perky C cups, could barely cover her nipples when she contorted her hand and arm. With her other hand she covered her now smooth pubic area. “I…ummm…didn’t realize you were home. Sorry, I—they cancelled my afternoon class, and I am going swimming. And I thought you had a lab or something on Thursdays?”

“Yes, I normally do have a lab on Thursdays, but it was cancelled as well. But again, why are you walking around naked?” Joe asked again, this time with a smile.

“Well, bro, if you must know. I put my bikini bottom on, and well, let’s just say that I had neglected my normal routine over the last several weeks and needed a shave.” Instinctively and without hesitation, Britt pulled her hand away from her pubic area, showing Joe how she just finished shaving and how smooth it looked. She realized quickly what she had just done and moved her hand back.

Joe stood there; he had not noticed that she was bald down there, as he was more of a tits man, and that was the only thing he saw as he came out of his room. With a slight cough to clear his throat, Joe said, “Well, now I see that. I didn’t need to see it, but now I have, and that is a picture that I will have burned in my mind.”

“Oh fuck me, Joe, shit, I didn’t mean to do that, sorry, you know me, I like to talk with my hands, and well… Also, could you please move so I can go to my room and get dressed?”

“Oh shit, yeah, sorry.” Joe said as he stepped back into his room to allow Britt to pass by. 

“Yeah, make sure you get a good look at my ass too as I walk by,” Britt said with a smile, knowing she had a tight, firm ass that most women would kill for. She had toned it over the many years playing softball catcher.

Joe did just that; he watched his sister walk bare-assed and was impressed, to say the least. While Britt was getting ready, Joe decided he would join her at the pool; he threw on a pair of board shorts, grabbed a towel, and waited for Britt in the living room.

After several moments, Britt emerged from her room with a cobalt blue bikini. Joe watched as she walked and instantly felt that familiar twitch in his groin.

During their swim, Britt mentioned to Joe that her friend Carman had invited her to the Sigma Nu annual pimps and hoes party. Joe knew the party well and explained this would be his third year going and he really enjoyed it. Obviously, Joe knew he wanted to protect his little sister, but at the same time, he couldn’t be a hypocrite and tell her she shouldn’t go.

“Okay, look, I know how this party is and the reputation it gets around campus,” Joe wasn’t really comfortable saying the next part, but he just pressed on. “I know what these guys want, and well, from what I see now and saw back in the apartment, they're going to be all over you.”

“Shut the fuck up, Joe, I know how to handle myself in situations…” grabbing her tits and pushing them up almost to the point of pushing them out of her top, “Do you think my tits grew overnight?” Britt started laughing again when she saw the look on Joe’s face.

“I…um…well, I just want to protect my little sister,” Joe stammered out. He could also feel his cock growing and getting thick in his board shorts.

“No, no, Joe, eyes up here. I see now you’re a tits man.” As Britt was saying this, she was bumped from the rear by a float. This made her jump a bit and fall into Joe; that’s when she felt his stiffening cock poke her pussy through her bikini bottom. She immediately stepped back with a gasp.

“Joe, was that your dick that just pushed up on my pussy?” 

“I think so. Sorry, but you fell into me; I didn’t move.”

“Bro, weird… But it’s okay. I think on that note I’m going to head inside for a quick nap before the party tonight,” Britt said.

As Britt turned to walk away, she smiled and quickly gave Joe a tap on his not completely erect cock with her hand. This sent an electric shock coursing through Joe’s body. “What the fuck, Britt‽” exclaimed Joe in a hushed tone.

Britt just smiled and winked as she pulled herself out of the pool. Britt thought to herself, ‘Although it was a quick tap, I could feel Joe has a decent-sized package.’

Joe had to wait a bit before he dared to exit the pool. After talking with Britt, bumping up against her pussy, and the tap on his cock, he was not going to be soft enough for people to not notice. At this point he was so horny it might be an hour before his cock became soft.

Later that evening, Joe was sitting in the den of their apartment when Britt walked in the front door with a brown paper shopping bag in hand and her friend Carman following. Introductions were made. Joe found Carman to be very sexy and what he considered to be ‘fun-sized.’ 

“Okay, so you two sit here and talk while I go and change into my outfit for the party. I will come back out here and model it for you guys,” Britt said.

Britt went to her room to change. Meanwhile, Joe and Carman sat and chatted while they waited. Joe found Carman very interesting and easy to talk to. Carman found Joe very charming and witty. She liked that in a man.

“Hey, do you want to grab a coffee sometime?” Carman asked Joe.

“Yeah, that would be cool. Hey, better idea, I know how these parties are and how late they can go, so I was thinking if you’re up to it in the morning, me, you, and Britt can go grab some brunch.”

“That would be fine—yeah, obviously not too early though,” Carman laughed.

“Obviously…” Joe trailed off as he heard the door to Britt’s room open.

Britt walked down the hall in a unique gold sequined dress that was very form-fitting. It was short, very short, and the top part was made from a sheer tulle fabric. If it had not been for the nipple covers, Britt’s nipples would have been on full display through the fabric. She was also wearing a pair of gold heels that looked very much like Louboutin’s.

Both Joe and Carman stared in awe at Britt as she walked down the hallway. Carman gave a catcall whistle. Joe was speechless. 

“Well, what do you think, guys?” asked Britt.

“I was skeptical when we saw it at the store, but, goddamn hoe, you wear that dress better than I could ever have imagined!” said Carman.

Laughing, Carman continued, “I’m going to look like a common crack whore in my outfit if I'm standing next to you.”

“Joe, what do you think? Will I fit in at the party, or is it too much?”

“Ummm… No, you’ll fit in just fine. I think I might have to beat the guys off with a stick though.” Joe said, smiling but trying to sound tough.

“Okay, so I have to head back over to my place and start getting ready. How about we meet outside the party at, say, 9?” asked Carman.

Joe looked at Britt and then back at Carman. “Yeah, that sounds good.”

After Carman was gone, Joe took his seat beside Britt on the couch. “So, what do you think of Carman?” asked Britt.

“She’s a nice girl, very pretty, smart, and easy to talk to. While you were getting changed, we decided to do brunch tomorrow, the three of us.”

“Oh really, that fast? What makes you think any of us are going to be in any shape or even here tomorrow morning to go get brunch?” Britt said with a laugh.

“Well, I…” Joe tried to think of something their dad would have said, but nothing came to mind. “Yeah, it’s just plans with nothing concrete.”

“Anyways, I need to go shower before this party,” Joe said as he was getting off the couch.

“Okay, cool, but do me a favor and leave the bathroom door unlocked; I need to do my makeup,” Britt said.

“But, I will…” Joe started to say before Britt cut him off.

“Look, the shower door is frosted and textured, so I won’t be able to see anything, plus I’m doing my makeup and not worrying about your naked ass in the shower.”

Joe took a deep breath and sighed, “Yeah, sure, whatever.”

Britt popped up off the couch carrying her shoes as she walked back towards her room in front of Joe.

Just as she was about to go into her room, she dropped one of the shoes and bent over to pick it up.

Joe noticed this and watched as Britt bent over. The back of her dress pulled up, exposing a bit of her ass and her pussy mound. Joe couldn’t help but stare and thought to himself, ‘Fuck me, she’s not wearing any underwear, and I can see my sister’s pussy.’ Instantly, Joe felt a twitch in his groin.

Britt, smiling, knew she had done a naughty thing but just couldn’t help herself. There was something about the way she was dressed and the party they were going to that was driving her wild. She also loved it when men or women looked at her in that sexy, seductive way.

It was all Joe could do to keep his cock from going full-on erect. He hopped in the shower and let the warm water do its thing. Joe heard the door open, and Britt entered the bathroom.

“Hey, let me know when you're about done in there and I will leave so you can get out,” Britt said.

“Okay, but this is still a bit weird, you being in here while I shower.”

“Dude, I can’t see a thing,” Britt fibbed. Standing in front of the mirror doing her makeup, she could see the shower; although it was frosted glass, she could see the outline of Joe, and in profile she could see he was well hung, just as she suspected from when his cock pushed up against her pussy in the pool.

Eventually, they were dressed and ready to go. They took an Uber to the party and met up with Carman. She was standing on the front porch of the house.

The instant Joe saw...
