A tale of 2 sisters

Chapter 1

"Hey, Abyss, put on a shirt; my sister is moving her stuff over soon and will be here in about five minutes," said my wife as she bustled around our new resale flat, cleaning up. We had only just moved in a few days ago, a proud achievement for a young couple.

"Well, okay, sigh... from now on I can't walk around half-naked anymore..." I said as I threw on a simple T-shirt. However, deep in my mind, I couldn't wait for this next phase of my life to start. We had been married for about two years. I would say we were still in our honeymoon phase as the sex still felt fresh, but having my wife's youngest sister (Emily) stay with us was like a dream within a dream.

My wife is the same age as me, much smaller in size, slim, with an above-average bust, and a nice round bottom. Her family is largely based overseas, including her parents and multiple siblings, and she came to Singapore to work during her late teens. She works in an industry that does shift work, with occasional night shifts. I work in a similar industry, but thankfully I have 8-5 working hours.

My wife has a fiery temperament but is often tender and endearing. I have a large fetish for underwear, and I was pleasantly surprised that she had a large collection of panties, both plain and pastel, and lacy thongs. My wife is rarely aroused, but is very obedient, and will gladly put on her lacy garments for me whenever I ask and is usually very submissive when I initiate sex. Once her engine is started, however, that's a different story.

Life as a couple in our rented flat was already good, with frequent sex, showers in tandem, and walking around the house naked, but my heart (and my cock) couldn't help but leap when my wife suggested that we let her youngest sister stay with us when we secured our resale flat. Emily was a fresh university graduate from a local university and had secured a good job in the area. My wife felt that she would do her youngest sister a favor by letting her stay in our place for minimal rent. If it were up to me, I would have gladly let her stay for free.

Emily looked very much like my wife, but she was even smaller in general. We had minimal interactions in the past, although she always came over to our rental flat to hang out with her sister. I always felt awkward around her, mostly because I was frequently lusting after her in my mind and I was afraid it would show on my face. It didn't help that she frequently wore tight and short skirts, but I had no luck in looking up her skirt during the time she was at my rental flat.

Having Emily over would mean more discrete couple activities between my wife and me, which I initially jokingly protested, but in my mind, all I could think about was being able to see Emily in her loungewear around the house, and being able to rummage through her underwear drawer and laundry baskets.

She came over shortly after, dressed in a simple white t-shirt and FBT shorts. Her shirt was thin, and the imprint of her half-bra was clearly visible. She was an innocent girl, and such mistakes made me so aroused. We helped her to move her luggage and boxes in and took a break for some drinks afterward.

Emily stretched, thrusting her chest out, making the bra protrude even more. I couldn't tear my gaze away, but I had to be cautious in case my wife noticed. She adores her younger sister immensely, but she is also fiercely possessive of me, and I dread what would happen if she knew what I thought of her younger sister.

Next came the opening of boxes. My wife and her sister had the same habit, often using multiple layers of tape to secure their boxes. Secure, but so difficult to open. Emily would be staying in the common room, so my wife and I began to open the boxes in Emily's room while she packed her luggage outside.

We tediously opened them, sifting through piles of notes, textbooks, clothes, and other belongings. As we cut through the tape of one of the boxes, I was suddenly greeted with my jackpot. Rows and rows of bras and panties were visible. Granted, not as large as my wife's collection, but still a sizeable amount. The bras were pastel and utilitarian, mostly black, white, and beige, with the occasional baby blue, pink, and red.

The panties were much better; schoolgirl-like, white and pink, with lace on the edges. Some were adorned with cute ribbons, and others had designs of flowers on the front. Immediately, my mind wandered, imagining Emily modeling her underwear in front of me. Her breasts were covered by soft bras, and her buttocks were accentuated by her panties. I started wondering what I would do if presented with such a sight.

I had to restrain myself, though. I managed to quickly say "Oops," and my wife laughed and said, "Yeah, sorry we found your underwear." Emily quickly came in, and with a giggle, apologized and took the box away to pack at her own pace. I suppressed the urge to tell my wife how different Emily's choice of underwear was from hers and continued packing. I hoped my wife didn't notice the gradually growing bulge in my pants.
