Desc: Erotica Sex Story: Months after Tom married the domineering Amy he learned that she had a sister, a twin sister, Alicia. Alicia had fallen on hard times and needed a place to stay. Once she had moved in, Alicia attempted to seduce Tom. She was about to learn the hard way that no one steals from Amy.

I met Amy Parker during college. She was studying to be an engineer while I was enrolled in the school's business program. I knew I wanted her from moment I first laid eyes on her during one of the core requirement courses that we both had to complete for our majors. Not only was she beautiful, but she was brilliant. I had always had a thing for smart women. I was relentless in my pursuit, refusing to be dissuaded by the initially cold reception. Eventually she warmed to me and we started dating. When I asked her, much later, what had changed her mind, she had responded simply, "I realized that you weren't a threat." She refused to tell me what it was that I didn't threaten. That'll teach me not to question my good fortune.

I should probably describe Amy. She was a petite woman, barely topping five feet in height even in heels. She had thick, shoulder length raven hair which she always wore in one of two ways: pulled back into a severe bun or bound tightly in a single thick pony tail. Her brown eyes were exceptionally large and liquid, tilting ever-so-slightly downwards toward her pertly upturned nose. Her lips were full and sensuous and her breasts, while just barely a c-cup, appeared huge on her diminutive frame. Her most outstanding physical feature was her round, firm ass, a perfect bubble above legs kept shapely and strong by daily jogging sessions around the campus.

From the moment we started dating, I couldn't help but notice that she carefully avoided any mention of her family or her past. Her dorm room and, later, her apartment were heavily decorated with photographs of her and her college friends, including, I am happy to say, myself, but there was not a single one that pre-dated college. I have to admit that it became something of a game to me. I would start to broach the subject of parents or hometowns or siblings and then laugh to myself as she scrambled frantically to change the subject.

We were surprisingly compatible. I had always been rather easy going so I was able to tolerate her need to control every aspect of her environment. Part of me, a shamefully large part, even enjoyed having nearly every minute of my life carefully structured and meticulously planned out in advance.

During our senior year, I proposed to Amy and she accepted. We were married in a quiet civil ceremony attended only by a handful of close friends and my parents. Upon graduation, it was no surprise to anyone that she received the more lucrative job offer. We immediately moved to the suburbs of the large mid-western city which was home to the company that had made that offer to begin our life together. Once there, I plastered the local companies with resumes and eventually secured a middle management position.

It was a pleasant existence, the only conflict being that I wanted to have children while Amy wasn't interested in anything that could derail her career. Then one Friday night, about a year after our move, we were in the middle of our traditional weekly love making - I had never actually dared to look, but I imagine that this activity was carefully scrawled each week into her day planner: Friday, 9 p.m-10 p.m., make love to Tom - when everything changed. We had barely gotten started and she was just beginning to assume her usual position on top of me when the phone next to the bed began to ring. Amy's lips tightened slightly at this unscheduled interruption, but she moved to answer it. She said hello, listened for a moment and then, her voice rising dramatically in pitch and volume, said, "Alicia?! How did you find me?" I was then treated to the sight of her firm, naked wiggling backside as she retreated to the bathroom, closing the door tightly behind her.

When she emerged twenty minutes later, she looked more troubled, more vulnerable than I had ever seen her. She laid on the bed next to me and clutched me tightly to her. "That was my sister, Alicia.", she whispered.

Seizing the opportunity, I said, with feigned casual interest, "Oh? I didn't know you had a sister."

She was silent for a moment and then, with a sigh, began to elaborate, "She's not just my sister, she's my twin. Growing up, she was the outgoing, vivacious one and I was the bookworm that lived in her shadow. Alicia was the prom queen and the homecoming queen and the head cheerleader. Our parents doted on her and celebrated each of her awards while completely ignoring my academic achievements." Amy paused for a moment, clearly reluctant to continue, "Alicia got everything she wanted and took everything I wanted. Any time I showed interest in a boy, she would swoop in and take him away. We looked the same, but no one could resist her personality. When we graduated, she immediately married our high school quarterback and everyone celebrated what was sure to be a perfect union. Our parents never even asked me about my college plans, other than pointing out that they didn't have the money to pay for it so I had better get a scholarship. So, when I did get a scholarship and left for college, I decided to make a clean break. I promised that I would never be one of the Parker twins again, but would just be Amy. I didn't even go back when our parents died in a car accident my freshman year."

I was startled, and more than a little disturbed, by these revelations, but I continued to listen in silence. Amy's voice took on a slightly vindictive quality. "Things apparently didn't go so well for Alicia after I left. Her husband washed out of college football and didn't do very well academically. He ended up selling insurance for one the hometown agencies. She thought they were doing well; they had a nice house and a new car and she was able to play little miss homemaker. Turns out that he was embezzling from his company and didn't do that very well either. When he realized that his boss was on to him, he emptied the bank accounts and left for parts unknown. The court decided that Alicia's tidy little house was a product of the crime and seized it for restitution. So now she's homeless, destitute and has no job prospects whatsoever. That call we just got was her begging me to take her in. She is still my sister and the only family I have, so I said yes."

Amy went silent and showed no further interest in discussing the matter. I noticed that she hadn't consulted with me before making the decision and didn't even ask how I felt about the situation. I tried to resume our lovemaking, but she was unreceptive.

Two days later we drove to the bus station to pick up Alicia. There was no chance of mistaking her among the crowd. She looked exactly like Amy, the only difference being that she wore her hair loose and, even after more than a day on the bus, it hung in soft waves which fell to the middle of her back. She immediately ran to Amy and gave her an exuberant hug which Amy returned stiffly. "Thank you! Thank you for doing this, sis.", Alicia bubbled. Amy introduced me and I held out my hand in greeting, but Alicia ignored it and enfolded me in a tight embrace as well. "Nice to meet you, Tom! I didn't even know Amy was married.", she gushed. Behind her back, I saw Amy's eyes tighten in disapproval.

The next few months were, in a word, tense. Amy had interceded with her employer on Alicia's behalf and made arrangements for Alicia to be employed part time in the company mail room. Alicia apparently did the job well enough, but quickly gained a reputation as an outrageous flirt. Much to Amy's annoyance, male employees of the company were soon seeking any excuse to run a quick errand to Alicia's department. At home, Alicia did help with the housework, but it soon became obvious that she liked a bit of clutter. Amy was quietly furious at the disruption to her orderly environment. Probably worst of all from Amy's perspective Alicia also shamelessly flirted with me. As she walked about the house, she would seize on any excuse to brush up against me or run a hand caressingly across my back or down my arm. In addition, I would often return home from work to find her sunning herself in the back yard wearing nothing but the wisp of a thong bikini and in the evenings she would lounge about the house wearing the skimpiest of nightwear.

Although my fear of Amy's wrath far outweighed any lust that Alicia was inspiring, I could tell that Amy was feeling threatened. For one thing, she expanded our weekly scheduled sex to include Monday nights as well as Fridays. During these sessions, Amy was far more vocal than she ever had been before, with the obvious intent of making certain that her sister knew what we doing. She also began showering me with public displays of affection, often holding my hand in the evenings and giving me spontaneous little hugs and kisses. I quietly enjoyed being marked as territory.

Then Amy's company sent her across the country for a week to help a subsidiary work out some difficulties that they were having with a new product line. During the week, Alicia did her best to seduce me, but I remained loyal to Amy. On the Friday that Amy was due to return I got tangled up in a little paperwork snarl at my job and didn't make it home until fairly late. Upon my return, I found the house silent and seemingly empty. There were no new voice mail messages so I went to the computer to check my email. My inbox was empty other than the usual spam but I noticed that I had two new messages in the deleted folder. Curious, I checked them and discovered that both messages were from Amy. The first told me that there had been a mix up with her flight and she would not be home until she could make other arrangements. The second reported that she had booked a flight for the following day and gave me her new flight number and time of arrival.
