This story, like most stories, is a small part of a much larger tale. The part I want to tell you about my relationship with my stepsister, which began when I was 23, after the worst break-up of my life. I had been dating my girlfriend, let's call her Shannon, for something like four years. In all honesty, I thought we were going to get married someday. Then I discovered that she was cheating on me, and I dumped her. I was devastated. I began drinking heavily and trying to meet girls in bars.

I lived with my mother and stepfather at the time because rents are so high where we live. Also living in the house was my stepsister, who had just turned 18 a few months before, but I'll come to her shortly. My room was in the basement, nicely sequestered from the rest of the house. I had a private entrance, which was nice, and I used it to bring home my one-night stands. I should also note the sliding closet doors that lined one wall of my room; they will come up later in the story.

I came home one night with a half-drunk barfly whose name, I think, was Pam. She was short, red-haired, and had absolutely the smallest breasts I have ever seen. I didn't much care though. We barely made it to my room before we started tearing each other's clothes off. There was no tenderness involved here, just straight animalism. I pushed her onto the bed, and began removing her jeans. Her panties slid right off with them, revealing the pink furrow between her legs.

Wordlessly, I began kissing her neck. I moved down her front, taking one of her tiny nipples in my mouth. Pam cooed. I moved to the other nipple, and then worked my way down to her pussy. I kissed her roughly, gently, sliding my tongue inside of her. I felt her body begin to convulse, and her hands grasping at my hair. I have no idea if she was faking it or not, and in all honesty, I really don't care.

After Pam's "orgasm," I lay down on the bed beside her. Now it was my turn. She began kissing me, but I just shoved her head towards my dick. She took it in her mouth, and began to suck me. I wish I could say that I came all over her face, but that would be a lie. I hadn't cum since Shannon and I split up. Maybe it was my anti-depressants, I don't know. In any case, Pam got tired of sucking before I got tired of being sucked.

That was not my last encounter with Pam. It was maybe two or three nights later, and she was over again. She was on top of me, riding me, when I heard something topple over in my closet.

"What was that?" Pam asked. She slid off of me, pulling up the covers to cover herself.

"I don't know," I answered. I got up, buck naked, and walked over to the closet. One of the doors was cracked open; I slid it open a few more inches. What I saw in the closet shocked me. It should have horrified me, but it didn't.

My stepsister, Mary, was sitting there on the floor. Her long brown hair was disheveled, and her pants were unzipped. Her left hand was shoved down the front of her pants. A stack of long forgotten schoolbooks had toppled over beside her. She stared up at me, her big eyes full of fear. My dick bobbed perilously close to her face.

"What was it?" Pam asked.

"Nothing," I said. "Just some books fell over." I smiled at Mary, and then closed the door, but not all the way. She was in there, watching me, and somehow I was more turned on than ever.

I returned to the bed, tore the covers away from Pam, and climbed back on top of her. I pushed her on her stomach, spread her legs, and began to fuck her doggy style. The idea of Mary watching me, and masturbating while she did it, filled me with more lust than I had ever known. I knew I was going to be able to cum. When I got close, I pulled out of Pam and told her to blow me. She complied. Moments later, I began to cum It came out in stuttering convulsions, filling her mouth, and then spurting all over her face and lips.

After Pam had cleaned herself up, I escorted her to the door. I gave her a little peck on the lips, and watched her drive away. Back to my room then, and to my stepsister spying on me from the closet. I opened the door, and there was Mary, sitting there with tears streaming down her cheeks. She hadn't zipped up her pants, I noticed. It looked like she hadn't moved at all.

"So," I said, towering over here. "You want to tell me what's up?"

"I'm...I'm so sorry," she blurted out. She broke down into a fresh stream of tears.

"Come on," I said. "It's ok." I offered Mary a hand, and, after a moment, she took it. I helped her out of the closet, and sat her down on the corner of my bed. Finally, she stopped crying. It hurt me to look at the fear on her pretty face.

"I'm sorry," she said again. "I'll never do it again."

"First, tell me what you were doing in there."

"I was watching you," she said, stating the obvious.

"And why were you doing that?"

"Because I...oh never mind. It's stupid." She turned away dramatically.

"Mary," I said, "tell me."

She turned back to face me, her face full of seriousness. "I love you," she said.

"I love you too."

"No," she said. "I mean, I'm in love with you."

I was stunned. My stepsister was in love with ME? Was she kidding?

"I know that sounds ridiculous," she said. "I feel stupid even saying it, but I can't help it. I've been falling in love with you for years, ever since that night."

That night, just so you know, happened about two years before. Mary and I were sitting up one night watching Letterman; we were talking during the commercial breaks. She'd been having some trouble with her boyfriend at the time, and had turned to her big brother for some advice.

"I...I feel really bad," she said, her face a mask of sadness.

"What happened?" I asked.

"Well, I think I went to far, and..."

"Mary? If something's up, you can tell me."

Mary and I had been close for some time. I think the bad divorces we'd both endured had given us a special kind of insight into each other's lives. Still, the implications of what she was saying were shocking to me. Mary had always seemed something of a prude, and had sworn up and down that she wouldn't have sex until she was married.

"I let Danny finger me," she said, then buried her face in her hands.

"Honey, it's ok." I put and arm around her shoulder and wrapped her into a hug.

After a long moment, Mary looked up at me. Her face was bright red. Apparently Danny had gone around telling everyone at school he and Mary had slept together. Her reputation was ruined, or she thought it was anyway. The situation blew over, of course. No one believes kids who say they've been laid at least not back then anyway.

We started getting closer after that. Mary would come to me whenever she had a problem, and I always tried to be there for her. I did notice, however, that after she dumped Danny, she never picked up another boyfriend. It was like she wasn't interested or she was saving herself for the right person.

"You've been so nice to me," Mary said desperately. "And I just couldn't help falling for you. I'm sorry, I know it's wrong, but when you and Shannon broke up, I was happy." She started crying again, and once more I found myself embracing my stepsister. When I looked down, I noticed the top of her pink cotton panties.

Mary is beautiful, but not in the stereotypical way. She has small breasts, though not as small as Pam's. Her ass in nicely rounded, and she has a creamy, flat stomach. She's thin, though her thighs are a little fatty. Her hair falls down around her face in long, dark tangles, and she has the sexiest voice I've ever heard.

"Mary, Honey, it's ok." I hugged her until her tears subsided, then we sat there in uncomfortable silence. She had spied on my, invaded my privacy, seen me naked. Could I just let this pass? I thought about how turned on I was know my stepsister was just a few feet away, touching herself. "Why were you watching me?" I asked.

"It turns me on," she admitted. "I imagine that it's me you're fucking, and I...I touch myself." She turned bright red, and buried her face in her hands.

"Wait a minute," I said. "Have you done this before?"

Mary nodded.

"For how long?"

"For a few months," she admitted. "I...I was watching the night you found out about Shannon cheating on you."

I thought back to that horrible night the night I finally lost my cool and struck a girl for the first and only time in my life. I punched Shannon in the stomach. I'll never forgive myself, but at the same time, she fucking deserved it. She was your typical sorority slut, and had been banging guys at parties since she went away to college. Whatever, I don't want to talk about that anymore.

"I could be your girlfriend," Mary insisted. "It's not like we're actually related."

"Mary..."

"I'd do anything for you," she said. "I'll let you fuck me."

"Mary," I said, then stopped. The expression of pure love in her eyes warmed my heart. I was so lonely, and the lifestyle I'd been living was so empty. But this was my stepsister, someone who lived under the same roof as me. What would we tell people?

"Mary," I said, "we can't."

"Please? I love you."

"I know. I love you too. But we can't."

Tears welled in her eyes. "You're mad at me," she said, "because I spied on you."

"No," I promised. "In fact, it kind of turned me on."

"It did?"

"Yeah." I wiped away her tears, and then, almost instinctively, I kissed her on the mouth.

"Oh God," she moaned. "I love you so much. Please love me."

"I do." I kissed her again, and she opened her mouth to me. My dick was as hard as iron, and I wanted more than anything to make love to Mary. But I could not.

"We have to stop," I said.

"Please don't."

But I did. I sent her away, and stayed up half the night jerking off. I imagined making love to my stepsister, and ended up coming all over myself.

I never saw Pam again, and that was on purpose. But a few nights later, I came home with another chick I picked up in a bar. This one was black, or maybe mulatto. She was curvy in every way conceivable, had a fantastic ghetto booty, and full lips begging to be cum upon. I think her name was Samira.

We were fucking wildly, when I looked over and notice my closet door was open just a crack. I wondered if Mary was in there, watching. We had not spoken about that night since it happened, and things still felt unsettled. After Samira was ushered out of the house, I returned to check on Mary.

When I opened the door, there she was. I sort of knew she would be there, but she did manage to shock me again. When I looked down at her, I saw my stepsister was totally naked. She was masturbating, and biting her lower lip in concentration.

"Mary," I whispered. "What are you doing?"

"What does it look like I'm doing?"

"It looks like you're fingering yourself." I thought my crudity would stop her, or embarrass her, but it did not.

"You want to do it?" she asked. Oh how desperately I wanted to, but I knew it was wrong.

"You've got to get out of here," I said. "What if our folks..."

Just then, Mary began to cum. I watched in sick fascination she her body convulsed. She moaning quietly, and at the peak of her orgasm, she said my name.

Afterwards, a sense of shame must have swept over her. She hid her face in her hands, and made a futile effort to cover her nakedness. As I stood there, I could not help but stare at her. She was beautiful. Her little pink nipples were erect, and the lips of her pussy were pink and swollen. I wanted desperately to kiss those lips, and it took all of my restraint not to jump on top of her right then and there.

Instead, I offered her a hand. Reluctantly, Mary took it. I helped her to her feet, and she stood there in my closet, naked as the dawn.

"Come on," I said, helping her into the room. Mary followed, her face bright red. I led her to the bed, but instead of sitting on the corner this time, she crawled across the ruffled covers and into the center of the bed, to the spot most recently occupied by Samira. I got a great view of her pussy and asshole as she crawled, and again my strength was tested. I wasn't sure how much longer I was going to be able to hold out.

"Mary," I said. "What are you doing?"

"I want you," she said, her voice sending shivers down my spine. "Please say that you want me too."

"Mary, I do. I...want you so bad. But it would be wrong."

She spread her legs, and ran a hand down her virgin body. She caressed her own nipples, and then began to touch her pussy. It glistened invitingly, and I could feel myself getting hard. "I don't care if it's wrong," she said. "All I know is that I love you, and I want you."

My strength failed. Without another word, I stripped out of my clothes. I was on top of Mary a second later, passionately kissing her open mouth. Her tongue was silky and sweet, and the thought of kissing my stepsister turned me on so much that I nearly came right then and there. But I didn't. I pulled away from the embrace, and began kissing her neck. I stuck my tongue in her ear, and felt her body tense. I took each of her nipples in my mouth, and as I did, Mary ran her fingers through my hair. I never thought I could want someone so much; thoughts of Shannon were completely gone from my mind.

I continued working my way down Mary's body, licking her navel, her stomach, and then finally the warm, pink mound of her pussy. Her pubic hair was soft, and I can still remember the feel of it against my lips. I began kissing the glistening mouth of her pussy, and when I did, I felt Mary's fingernails dig into my neck.

"Oh God," she moaned. "That feels so good."

I slowly inserted my tongue into her pussy, and began licking her. She tasted so sweet, and the action was driving me wild. I couldn't stand it anymore. I lifted myself up from her soaking wet pussy, and prepared to fuck my stepsister. I took one last look at her she was the sexiest thing I'd ever seen. Her hair was spread out across my pillow, and her naked breasts heaved with each breath. I crawled on top of her, and pressed my dick against her. I felt her pussy opening to accept the head of my cock, and at the same time, I heard Mary sigh.

"Wait," she said in a terrified whisper. "Please wait."

Of course, I stopped.

"Mary? What's the matter?"

"I...I'm scared," she admitted.

"Are you having second thoughts?" I asked.

She nodded. A moment later, she began to cry.

I laid down beside my stepsister, and took her in my arms. I was desperately horny, but I wasn't about to rape her. "Mary, Honey, it's ok," I said. "We can just pretend like none of this ever happened."

An expression of seriousness shone through her tears. "I don't want that," she said. "I want you. It's just..." She stared at me, her eyes begging me to finish the thought.

"You don't want to go all the way until you get married?"

Mary nodded.

I lay back against my pillow, frustrated as hell.

"We could do other stuff, though," she said. "I mean. I'd do anything else you want, just not that." She smiled innocently. The lines of her tears were still evident on her cheeks.

"Like what?" I asked.

"Well," she said, "I've never done it before, but I was wondering..." Again she stared at me with those desperate eyes, but this time I made her say what was on her mind. "I was wondering," she said, "if you would let me suck your dick."

Mary's hands shot up to hide her face, but I caught them by the wrists. I gave her a single, deep kiss, and then nodded. I lay back against the bed and motioned for her to proceed.

My stepsister sat up, and began to straddle me. I could still feel the warmth and wetness of her pussy, and I wanted so much to be inside that quivering womb. But it was not meant to be. I lay there as she lowered herself to my dick. Her hair poofed out in wild tangles, but I didn't care. She looked so sexy, holding the shaft of my penis in on hand, and silky pink tongue peaking through her lips. She stared at me with those gorgeous hazel eyes, as if to ask if I was sure this was ok.

"Go on," I said. "It's ok."

Mary kissed the tip of my penis, and then slid its head into her mouth. I realized at once that she could probably taste Samira's pussy on my cock, but she never mentioned it. Mary began working me with her tongue, and already I could feel my orgasm building. She was inexperienced, and I had a feeling she'd never done this before. It was a little painful, her teeth hurt me just a little, but oh how she would improve over time. She tried once to take me deep into her throat, as she had observed my ex-lovers do to me, but she gagged. So, she just kept working the top of my dick, and the pressure became to much to bare.

"Mary," I whispered, "I'm going to cum."

She stared nervously at me, a bit of fear in her eyes.

"Honey, can I cum in your mouth?"

The fear was still in her eyes, but she gave a terrified little nod. A moment later, my body was wracked with a massive orgasm. I came in my stepsister's mouth, and when she began to choke on it, a large dribble of come poured from the corner of her mouth. I could see it like a glaze on her lips, and there was even a little bit on her cheek. She swallowed some, and spit the rest out on the floor.

When she lay down beside me, she was smiling tentatively. "Was I ok at it?" she asked.

"Mary," I said, "you were wonderful."

That was the beginning of our relationship. After that night, there was no way I was going to go back to picking up girls in bars. I started staying home, and spending most of my free time with Mary. We had so much in common, and for the first time since Shannon and I split up, I was really happy.

Mary and I spent most nights in each other's arms. We would sleep together until 3 or 4 in the morning, and then she would go back upstairs to her room. I loved her like I had never loved anyone before, and my feelings for her put my feelings for Shannon to shame. But there was something beginning to bother me, and it would only end up getting worse as time wore on. This relationship, no matter how wonderful, was doomed to failure. I just didn't see any good way for it to end. As it turned out, the end was even worse than I could have imagined.
