Stephanie had just returned from an evening out with my sister, Liv. My beautiful wife was tipsy and stumbling around the bedroom as I settled into bed.

"How about joining me in bed?" I asked, pulling her warm body tightly into me.

I was hoping the night would take a sexual turn; however, those hopes were quickly dashed.

"Guess what, Jacob? Liv and I booked a trip to the Bahamas for the three of us!" Steph blurted out.

I was taken aback by her sudden announcement.

Stephanie noticed my surprise and quickly added, "I thought it would be an excellent way for all three of us to reconnect. The two of you barely see each other anymore."

I couldn't believe it. My heart raced as I listened to Steph explain her reasoning.

"Liv and I were bitching about how badly we needed a break. After a few drinks, we found ourselves on our phones, booking a trip to the Bahamas," Steph explained.

I looked at her, unsure of what to say.

"Plus, I know how much you love your sister, and I wanted to find a way to bring us closer together," Steph continued, trying to allay my concerns.

I did love my sister, but the thought of spending a week at a beach resort with Liv terrified me. Liv was only a year younger than me. Growing up, we were inseparable. So much so that when it came time for her to decide where to attend college, it wasn't a question; of course, she would join me at Rutgers.

From the moment she stepped foot on campus, you couldn't keep us apart. It got to the point where our friends would joke that if we weren't siblings, everyone would have thought we were dating. 

I didn't want to admit it, but there was a flirty nature to our relationship. We would constantly touch and tease each other. There was just something unspoken between us. How Liv looked at me with her big blue eyes let me know she felt the same way. 

Liv was gorgeous. Every one of our guy friends seemed to want her. They would endlessly try to get into her pants, but she never seemed interested. I sometimes wondered if our relationship got in the way of us dating other people, but I couldn't imagine changing things.

The truth is, there was something sexual about our relationship. I would often jerk off thinking about my sister. I would picture Liv in her little bikinis or one of the tiny dresses she would wear to frat parties. But it was just that, a fantasy. I never imagined anything would happen between us.

That all changed during the fall semester of my senior year of college. Liv was often my wing-woman at parties. The problem was that we would always end up dancing the night away. It is probably why she was so bad at helping me pick up women. Everyone always thought we were a couple. It didn't help that she often stayed in my bed after a night of partying.

Liv was a great dancer. Her graceful body would move perfectly in synch with mine. Despite being my sister, I loved the feeling of her body pressed against me. While I sometimes wondered if our flirtation was all in my head, that question left my mind whenever we danced. By the night's end, it always felt like Liv was on the precipice of kissing me, but held back because I was her older brother. 

Yet, one cold night, when we both struck out again, Liv crashed at my place. As we were lying in bed, Liv and I finally kissed. It was the most electrifying kiss I had ever had. Years of passion were finally released when our lips and tongues met. We spent that whole night making out. We didn't have sex; heck, I didn't even touch her under her clothes, yet in some ways, it was the most intimate I had ever been with a woman.

After that night, things changed between us. As much as we enjoyed our night of passion together, it terrified us, especially me. We knew nothing could come of our relationship, so we slowly started backing away from each other.

While we were still close, we made sure never to be alone together. A few years after college, Liv introduced me to her friend Stephanie. I often wondered if setting me up with her roommate was a way to keep me close while knowing that I was off-limits to her. Eventually, Steph and I married, and I rarely saw Liv anymore. We would talk, for sure, but we seldom spent time together. That is why going on vacation together seemed to come out of nowhere.

Despite being hesitant about the whole thing, Stephanie's enthusiasm was infectious. 

"Fine. Let's go," I acquiesced.

Stephanie gave me a tight hug, "You won't regret it! This is going to be the best trip ever. 

I could see the excitement in Steph's eyes, and it was hard not to get caught up in it. I was still a little apprehensive about the whole thing, but I trusted Stephanie's judgment. 

"Hey, Liv! I have some great news! Jacob agreed to come on the trip with us!" Steph exclaimed the moment my sister picked up the phone. 

I could hear Liv's elation through the receiver as Stephanie continued talking about the trip's details.

Steph then turned to me and said, "Liv and I were thinking of going bikini shopping tomorrow. Do you want to come with us?" 

I hesitated momentarily, unsure how I felt about my sister modeling bikinis for me, but Steph quickly chimed in, "Come on, Jacob! It'll be fun! You can help us pick out some cute swimsuits for the trip!" 

I finally relented and agreed to go shopping with them. The next day, we headed to the mall, and Liv and Stephanie immediately began browsing through racks of swimsuits. 

"What do you think of this one, Liv?" Steph wondered.

Liv quickly glanced at it and shook her head, "We are going to the Bahamas, not your grandmother's pool," she teased.

"Oh, is that how it is going to be?" Steph chuckled.

While Steph had a fabulous body, she dressed conservatively and rarely showed off her assets. On the other hand, Liv loved showing off her body to the world. In college, Liv's outfits would drive the guys mad with lust, myself included. The thought of my wife dressing similarly caused my pants to tighten.

"Let's try a different store. There is a place on the second floor that has exactly what we need," Liv suggested.

Steph and I gave passing looks at each other, unsure of what we were getting into. 

"Here it is," Liv said, pulling us into a store called Forbidden Secrets. 

The name alone caused my cock to swell more. Looking around the store, I could see why Liv liked this place. There wasn't a piece of modest clothing in the store.

"You have got to be kidding, Liv. I can't wear any of this stuff," Steph yelped nervously. 

"Steph, you have an amazing body. You need to show it off more. We are only young once; take advantage of flaunting what you have while you can. Besides, I want to see your hot body in something a little skimpy," Liv teased. 

I couldn't believe my ears. My sister was flirting with my wife. Yet, I could see Steph's eyes light up from my sister's compliment.

"Fine. If I am going to do this, let's do this. I am yours to dress up," Steph submitted.

Liv grinned wildly as she pulled my wife to a row of bikinis that barely had anything to them.

Liv grabbed a handful of bikinis off the rack, each more revealing than the last. I couldn't help but stare at them as they walked to the changing room. They both looked incredible, and I felt a stirring in my pants as I imagined what it would be like to be in there with them.

My jaw dropped when Liv came out of the fitting room minutes later.

"So, what do you think?" Liv asked, twirling around for me. 

It was the first time I had seen Liv in a bikini in years, and this bikini left nothing to the imagination. Liv's hips looked wide, her stomach was toned, and her tits practically popped out of the minuscule red top.

Liv's ass was completely exposed, showing off her firm butt. It was clear my sister spent a lot of time in the gym.

"Wow. That is quite the bathing suit," I timidly laughed, trying to hide my arousal.

Not to be outdone, Steph soon came out of the fitting room in an even skimpier bikini.

"Does this look okay? Liv made me try it on," she asked self-consciously.

"You look amazing, Stephanie. I can't believe I am married to you," I gushed.

"Are you sure?" She asked, spinning around and showing me the back. 

As Steph turned around, I couldn't help but notice how little the bikini covered. The bottom was so obscene it barely covered her vulva, and the thin string that ran between her ass was almost non-existent. 

As I struggled to catch my breath, I couldn't help but notice that her hard nipples were clearly visible through the tiny top. The teardrop-shaped fabric hardly covered her breasts and offered little support. However, the barely-there top accentuated her toned abs and the subtle curves of her breasts. 

The bikini left very little to the imagination, and if we weren't in public, I would have grabbed her and fucked her on the spot. 

"Trust me, babe, you look hot. I can hardly control myself," I grinned.

"Wow, Liv, you look amazing in that bikini," Stephanie said, eyeing my sister up and down.

"Thanks, Steph," Liv replied, a sultry smile on her lips. "But I think you look even hotter in that red bikini. It really complements your tits."

Stephanie laughed, her eyes sparkling with mischief. "You think so? Maybe I should wear it to the beach and see what kind of reaction I get."

Liv grinned, her eyes flashing with excitement. "I think you should. I bet you'll get lots of attention."

I watched as the two women flirted with each other, their words and gestures filled with an electric charge that made my heart race. I couldn't believe how sexy they looked in their bikinis, and I found myself imagining all sorts of scenarios in which we could all be together.

After several hours of shopping, we left the mall with several bags of clothes. While they modeled most of the clothes for me, there were several outfits that both women said I would have to wait for our vacation to see.

The rest of the week passed by in a blur, and before I knew it, Stephanie, Liv, and I were on our way to the Bahamas.

The resort was nestled on the edge of a pristine beach. The resort was a sprawling complex of white-washed buildings surrounded by lush tropical gardens. This place was just what I needed to help wash away my nerves.

We checked in at the front desk, and that's when we hit a snag.

"I'm sorry, sir, but we only have one room in your name. However, it is a suite, so it should comfortably fit the three of you. It has a positively beautiful view of the ocean," the concierge informed me.

Stephanie and Liv were excited to share the room, making me wonder if this was their plan all along. 

"It will be fine. I'll take the couch," Liv volunteered as she rubbed my arm. 

As we made our way to our suite, I couldn't help but feel a bit uneasy. I had hoped for some romantic time with my wife on this trip, and the idea of sharing a room with Liv was not what I had in mind. 

But as we settled into the suite, my frustration dissipated. It was hard to stay annoyed when I was flanked by beautiful women in such a picturesque place.

"We still have a few hours before it gets dark. How about we go canoeing? The lady at the desk said we can take canoes out with a tour guide at the top of the hour," I suggested. 

Steph and Liv quickly agreed. It was clear that the three of us felt cooped up after half a day of traveling and needed to move. 

The three of us made our way down to the beach, where we rented a canoe. As we paddled through the calm waters, I couldn't help but feel the excitement bubbling up inside me. This was the life, and I was happy to be spending it with my two favorite ladies.

The water was calm, and we paddled in sync, enjoying the warm sun on our skin and the boat's gentle rocking. But as we started to make our way back to the shore, Liv and Steph began to flirt with each other. 

"So, Liv, what's your secret for staying in such good shape?" Steph asked, running a hand through her hair. 

Liv grinned. "Oh, you know, lots of yoga and healthy eating." 

Steph giggled. "Maybe you could show me some of those yoga moves later."

Liv winked. "I'd love to."

I couldn't believe my ears. Was my wife actually flirting with my sister? I knew they were close, but I couldn't help but wonder if more was happening. 

We returned to our room, ordered room service, and called it an early night.

I woke up the following morning to my sister bouncing on our bed like a child on Christmas morning. 

"Wake up, you sleepy heads! If we want a good spot and chairs, we need to be out there early," Liv exclaimed, pulling our blanket off. 

I wanted to be annoyed, but my sister's energy was contagious. Steph, on the other hand, had no problem being annoyed.

"Ugh, too much. Too much," Steph moaned as she pulled the blanket back over her head.

Liv crawled into bed beside my wife and smacked her ass, "Come on, Steph. It is time to show that ass off to the world." 

"You're insane, Liv," Steph yawned while pushing Liv off the bed. 

"I'm going to go shower. Hopefully, that will wake me up," I said, stumbling to the bathroom. 

I was right; a shower was just what I needed. After a day of canoeing, my body was sore. The hot water massaged my aching muscles, melting away any tension I had.

Despite all my concerns, the trip with Liv was going better than I could have hoped. I stood under the rushing water, wondering if staying away from each other all these years was a mistake.

As I hopped out of the shower, I felt excited for the day ahead in a way I never expected. 

"Showers free," I called out while searching for my swim trunks.

What I heard Liv say next shocked me to my core, shifting my excitement about the day to concern.

"Hey, Steph, why don't we shower together? It'll save time, and we can get out of here faster," she flirtatiously said.

I looked at my wife, unsure how she would respond. There was no way she would take Liv up on this. Besides, I am sure Liv was joking anyway.

"Okay, Liv, but only because we're in a hurry," Steph replied.

I was dumbfounded. I couldn't believe Steph was actually going to shower with my sister. I wanted to say something, but I worried about causing a scene. 

As I stood outside the bathroom, listening to the sound of the water running, my mind raced. What was going on in there? Were they really showering together? I felt a mix of curiosity and confusion. 

If I were completely honest with myself, I also felt jealous. All these years, I did everything I could to keep things platonic between my sister and me, and here was my wife in the shower naked with her. 

I could hear Steph and Liv laughing and chatting as they lathered up with soap. It sounded like they were having fun, but the idea of them showering together made me feel uneasy.

Suddenly, I heard Liv say something that caught my attention.

"Hey Steph, you missed a spot. Let me get that for you," Liv stated, her voice laced with mischief. 

I heard Steph giggle in response, and my heart skipped a beat. I imagined them touching each other, running their hands over each other's bodies. I felt like a voyeur, listening in on something intimate and private. The idea of there being something intimate and private between my wife and sister left me confused but highly aroused. 

As the water continued to run, I tried to ignore the sounds coming from the shower. But I couldn't help feeling like I was missing out on something. I wondered what it would be like to shower with both of them and feel their bodies pressed against mine.

Thoughts of my sister, naked, slick with water, pressing her tits against my back while my wife and I made out, ran through my mind. My cock strained against my swim trunks, begging to be played with, but I couldn't risk being caught with my pants down. 

Eventually, the water turned off, and they emerged from the bathroom. I couldn't help but stare at them. They both had water droplets running down their bodies, and I felt my trunks tightening even more. 

"You okay, Jacob? It looks like the cats got your tongue," Liv coyly said.

"Ugh, I'm still just waking up," I lied, trying to maintain my dignity. 

I watched the two women, still wrapped in their towels, searching through their bags for a bikini to wear.

"Which suit are you wearing?" Steph asked.

Liv held up a pile of strings that was supposed to pass for a bathing suit, "I think I am going to wear that micro bikini you dared me to buy."

"Well, if that is the case, I guess I will have to wear my micro bikini too. No way I am being outdone by you," my wife declared.

As Steph and Liv dressed, I felt my...
