AUTHOR'S NOTE:
I would like to thank everyone for the comments on the previous parts of this story. I am especially thankful for the constructive ones, as improving my writing is the primary reason for being here.
I would also apologize for what may be a disappointing end to this tale. I had planned a chapter for each year at school, but those sections proved frustrating to draw out. This is in part due to the fact that I had most of this ending written before that and it became difficult to extend the story without it feeling repetitive and unduly long. Apparently writing the last chapter of a story early is just as bad as flipping to the end of book to read the last chapter first.
**********
The start of college classes marked the beginning of Kelly's plan which I later learned she called operation summer rain. Over the course of her four years, drop by drop, she wore away at my armor. Unlike Deborah, most of the girls I chose for the house got a great deal of help before ever venturing into a rental agreement, usually over the preceding summer. I learned fairly quickly that it was beyond me to serve as a treatment center for more than one tenant at a time. But by now I had friends, contacts, and lots of help, and while treatment might continue in the house, tenants had to be mostly sound mentally and physically to accept the agreement.
During the first year of school, Kelly was mostly just one of the three girls in the house. She wore lingerie the entire year, nothing revealing, only things that hinted at what was there. I had found two other girls to bring into the house, one was an artist and the other a musician. Kelly's rain started slowly and she only broke a few rules. First, she lingered in bed with me after every coupling. Usually I ushered a girl out of my room quickly, but Kelly refused and I found myself unable to argue with her. In fact, on six different occasions she actually spent the entire night in my bed, which prior to this year, was completely verboten.
Her second break from house rules came in late January for my birthday. She popped into my room that night wearing nothing but a thong made out of ribbon with a bow tied just above her ass. "Enough practice," she announced, "it's time you got what you've wanted since last summer." That first time was slow and cautious, but we quickly discovered that both of us enjoyed the experience immensely. She was quite cunning after that, and she never let me have her ass during our normal sessions. Only on her terms and only on days she chose, which were always special occasions and holidays. She kept it just infrequent enough that each time was intimate and seductive.
During her second year, she took control of the girls in the house. Laura, the musician was still living there and I had added a business major named Mindy to replace our graduating artist. Kelly found her way to my bed after every session with either of the other two girls, cuddling with me and often sleeping with me afterward. Both of them seemed to know what was going on. She even reversed the process on a few occasions bringing one of the other two in to do the physical deed with me on the days of her sessions. It drove me mad, and made me want her all the more when she allowed it to happen.
That year, on her special occasions, she also connived to get me to take her on dates, which I had never done before. We saw movies, went to wine tastings, had numerous meals, and even made one overnight trip to Sedona. She was gradually insinuating herself into my everyday life and I allowed it to happen because every moment I spent with her was wonderful. At the time, I barely realized what was going on.
During her Junior year, it was just Kelly and Mindy as Laura had graduated and I never found a replacement. Later I would claim that I wasn't looking as hard, but who knows. It was during this year that we both discovered that Mindy was the first bi-sexual girl to stay in the house. She spent almost as much time in Kelly's bed as she did in mine, which made me either a bit angry or a bit jealous. I never really addressed what I was feeling and just chalked it all up to the newness of the experience. Our date nights turned into threesomes and so did several of our bedroom activities. But it was always Kelly that lingered in bed afterwards, and it was always Kelly who came calling on her special occasions. With only two women in the house, the sexual activities actually declined, but Kelly made every occasion more intense or more involved in one way or another. She also created events at the house for the three of us such as movie or tv marathons, game nights, and karoke.
In her last year, Kelly took over the house completely, even bringing in the two new girls that replaced Mindy. Heather was an artist with an eating problem, weight issues and low self-esteem all of which were well on their way to repair after six months. What I didn't know was that Heather was only minoring in art; her major was actually psychology and that the self-esteem issues were carefully orchestrated for my benefit. Amber was a music major with severe social anxiety problems that stemmed from a history of abuse. It took almost the entire year before Amber began to approach a more normal life outside the house, but she attached herself to Kelly almost immediately, treating her like a big sister and doing whatever she asked. It took six months before anything physical even occurred between us, and when it did I was reminded acutely of Deborah.
Bit by bit, piece by piece Kelly wore away at me. I was barely cognizant of the changes as no one else, not even Deborah, pointed out how things had changed. Even had someone pointed it out to me, I'm not sure I would have thought anything of it at any point along the way.
One night, a few weeks before the last semester ended, someone snuck into my room and incapacitated me while I was sleeping. She blind folded me and tied my arms and legs to the four corners of the bed. I didn't wake up until a few minutes after she started stroking my cock toward hardness. I felt a hand, but I had no idea yet who it was in those first few seconds of wakefulness.
"What," I shouted.
"Shhhh," came a whisper from my left.
I struggled a little against the restraints, but quickly realized I was not getting out of them on my own. I could move a little, but my wrists and ankles were securely tied. I moved my head back and forth repeatedly trying to dislodge whatever was covering my eyes, but that too, was set securely in place.
"What's going on," I said feeling particularly vulnerable.
I got no response beyond the steady stroking of my cock, which in short order had me fully aroused. I felt someone straddle me and then a hand took hold of me again and I felt myself fully engulfed by a pussy. Whoever it was, rode me slowly and steadily. Her pace increased gradually until I realized I would soon reach orgasm. Then she leaned forward and whispered in my ear.
"Who am I," she asked and then sat back slowing her pace.
"Kelly," I said realizing it immediately.
"How can you be sure," she whispered.
"Only she would sneak in here and do this. Heather and Amber would not break the rules like this, unless of course Kelly told them to."
"Anything else," came the next whispered question.
"You don't feel like Heather or Amber, you feel... better." I suddenly realized that Kelly had complete control over her body at this point, and more alarmingly, she had a great deal of control over mine apparently. Her pace kept me very aroused, very urgent, very close and she knew where and when to squeeze or contract. She made my desire rise and fall as she wanted, and only brought her own pleasure into it to affect my own.
"I like that answer," she whispered. "Anything else?"
"It's... different with you. With Heather and Amber it's just sex, passionate sex certainly, but still just sex. With you its... more."
I felt her lean forward again so she could whisper in my ear. "Good enough. Your homework is to ponder what you mean by 'more'. Since you've been such a good boy, I think you deserve a reward." She leaned back and began riding me faster and more firmly.
"Yes," I said urgently.
Then she suddenly slowed down and I growled in frustration.
"But, where do you want to cum," she asked. "Should I go back to work with my hand?"
"No," I said shaking my head.
