Author’s Note: This story is true, but I’ve changed the names and some identifying details to protect, well there may not be any innocents here but, the reputations of those involved.

My name is Nick and this is an episode of my life that happened some years ago when I was about eighteen.

My parents divorced when I was young and I lived with my Dad afterward. About two years after the divorce Dad married Terri, a really great lady whom I soon learned to love. Terri and her daughter, Rebecca Jean, came to live with Dad and me in our house. Like I said, Terri was great from day one, and it was clear, even to me, that she loved Dad and was very fond of me. Rebecca Jean was very quiet and serious at her young age, and it took me a while to discover that she was actually pretty cool.

It wasn’t long before she became my best friend, walking me to school, and letting me hang around with her and her friends after class. Although we were step-siblings, and Terri was my step-mom, I came to think of them as my Mom and sister very quickly.

RJ (that’s what everyone called Rebecca) was into gymnastics all through school, and I was into basketball and baseball, so there were a lot of extracurricular activities for both of us. But, because our school scheduled both girls’ and boys’ sports at the same time, it wasn’t often that we got to go to the other’s events.

This is about something that happened when we were later years of school. Because of our birthdays, I was able to start school early, so I ended up being just a year behind RJ.

One day, I had just gotten home from practice, and was on my way to my room. I had to pass RJ’s room to get to mine, and as I was walking by I could hear her crying through her closed door. I stopped for a moment to listen, just to be sure she was okay, but I could tell she was really sobbing hard.

“RJ, are you okay? Is there something wrong?” I called through the door. I waited a second or so and tapped on her door before turning the knob. I stepped in and found her sitting on the edge of her bed, tears streaming down her cheeks. “What’s wrong? Are you hurt?” I was really concerned because I had seldom seen her cry, and never with such racking sobs.

She looked up at me and tried to speak, but all she could get out beside her heart-wrenching wails was something that sounded like “hic-hic-aww” followed by a flood of tears. I closed the door and went over to sit beside her. I put my arm around her and let her cry into my shoulder until she could regain her composure. Finally, after a couple of minutes, she took a deep breath, wiped her eyes with the back of her hands, and told me in halting phrases what was wrong.

Her closest Best-Friend-For-Life, Denise, had accused her of sleeping with her (Denise’s) boyfriend. She called RJ a slut and said she would never talk to her again. Then she stormed off to tell all their friends what a slut RJ was. Of course the word spread all over school in nothing flat, and when Ramon, RJ’s boyfriend for the past year, heard, he dumped her saying she wouldn’t fuck him, but was fucking everyone on the track team and he wasn’t going to be known as the guy that went with the school whore.

Now I know RJ well enough to know she wasn’t sleeping around, and I was pretty sure she was still a virgin, so all of this was a load of crap and I started to get really pissed at Ramon and especially at Denise. I knew Denise wasn’t a virgin a number of times over, because I knew some of her ex-boyfriends and you know how guys will brag in the locker room.

“I’m going to find Ramon and knock the shit out of him,” I said. “He’s not going to talk about my sister like that.”

“Don’t do anything, Nick, please. It will just stir everything up even worse.”

“Well, okay, but I’m going to talk to him. Just talk, Sis. He should know better than believe this bullshit.”

RJ stroked my cheek and then gave me a big hug. “I love you, Nick. You are the greatest!”

I was feeling very protective, and it felt good to know she knew I believed her and would stand up for her. But something else, something totally unexpected happened at this point. I felt a pair of firm sexy tits pressing into my chest. And they felt fantastic! That is, until I suddenly realized what I was thinking—this is your sister, you fucking perv. I jerked back from her hug, her innocent hug, and felt horribly ashamed of myself.

RJ was startled at my reaction, jerking away like I did, and asked with concern, “What’s wrong, Nick?”
What was I going to say? I just got a feel of your boobs and it was turning me on?

“Uh, I just remembered that I hadn’t showered after practice, I must smell like a mule. Sorry, Sis.”

“Well you don’t, but if it worries you, go take your shower. I’ll be all right.

Thanks for being there for me, Sweetie.” Then she gave me a chase peck on the cheek.

As I opened the door, I stopped and turned toward her. “You sure you’re going to be all right?”

She nodded her head and waved me out.

I had never thought of RJ as a girl, I mean in a sexual sense before. She always wore loose sweats or baggy tops and slacks that disguised her figure. So I hadn’t really notice the change from little girl to voluptuous, sexy woman. About the only time RJ wasn’t wearing her usual asexual outfits was when she was doing gymnastics, and since I hadn’t been to one of her meets in years (remember that all our extracurricular sports were scheduled at about the same time), either I was at a game, at practice or she was, so our schedules didn’t match up very often.

A couple of days later, I had a chance to have a sit-down with Ramon about his churlish behavior to RJ. Turns out that he heard the allegations from “a reliable source’, RJ’s BFFL, Denise. After we talked for a while, Ramon said he would think about what I said, and talk it over with RJ. He had to take off and so did I so we left it at that.

After practice I headed home. I was once again passing RJ’s room and the door was partially open. I could hear her talking to someone, and then laughing. I waved at her as I walked by to my room and a shower.

I had just finished rinsing off after a long hot shower and had the towel over my head drying my hair when I stepped out of the shower stall. RJ and I share a bathroom with a door on her side and one on mine. Whoever is using the bathroom just turns the latch in the door on the other’s side to ensure privacy. On this particular day I had apparently forgotten to lock the door on RJ’s side, probably because she was engrossed with her phone call.

As I pulled the towel off my head I found myself standing dripping wet and completely naked in the middle of the floor and RJ standing in her open doorway taking in the view.

“Well hello, Little Brother, or should I say Big little brother?” Her eyes were firmly locked on my crotch and she had a big grin on her face.

I stood there, dripping on the floor, towel hanging at my side, as shocked as a deer in headlights. Suddenly my brain turned back on and I said, “What? You never seen anyone with just-washed hair before?” And I calmly pulled the towel up and wrapped it around my waist.

“Okay, you’re right. Sorry, I just came in to get my brush and the door was unlocked.” With that, she stepped over to her side of the counter and picked up the brush. With a devilish grin on her face she stopped and said, “You sure you don’t want me to brush your hair. . .or something for you?” and quickly ducked into her room and slammed and locked the door before I could throw something at her. I could hear her laughing through the door as I finished toweling off.

We never mentioned our bathroom encounter, although our sometimes oblique looks made it clear that neither of us had forgotten the incident.

Later that evening, RJ pulled me aside and said that she and Denise had made up and were back to being Best Friends For Life. It seems that the rumor about RJ and Denise’s former boyfriend was started by another girl who was fucking him and wanted to get Denise out of the way. So, RJ was happy again, she had her best friend back. She had also spoken with Ramon and decided if he couldn’t accept the truth, even when Denise confirmed it, the hell with him.

“Well, I’m glad things have worked out for you,” I said. “But what about the gossip and your reputation at school?”

She said that most of the girls at school had figured out what was going down, so the whispering had petered out. And as for the guys? Well, she was getting a lot more attention than before even though she was keeping the pussy-dogs at bay.

Over the next several weeks I was approached by several guys wanting me to fix them up with my hot sister. I made sure I told them that the rumors about my sister being “easy” were false, and from a certain mattress-back who I gladly named. I heard that she was getting a lot of new admirers afterward. But that might be just a rumor, one never knows about these things, does one?

Gradually things at school fell back into their regular routine. Summer break arrived and I was playing a lot of ball, RJ was hanging out with her friends their last summer together before the group drifted off to college or budding careers.

I think it was around the end of July when things underwent a huge change for me.

Dad and Mom were off to northern Idaho to visit some of Terri’s relatives. There was a new baby and a family reunion, I think. Anyway, RJ and I were left to our own devices for the week the folks would be away.

I had just come in from the local swimming spot after a day of fun and frolic with some of the kids from school. I was feeling tired from too much sun and too much beach volleyball, and was heading for a quick shower to cool off. RJ was in her room listening to some music as I walked by.

“Have a good time, Nick?” she called out as I passed by. “If you haven’t eaten, let’s go out for something. I kind of fancy Chinese. That suit you?”

“Sounds good to me, but I want to take a shower first. I must have a half the beach sand sticking to me. I won’t be long, then we can go.”

After I had showered and changed into some fresh clothes RJ and I headed out for dinner. We stopped at our favorite Chinese buffet and ate outside in the garden area. We were talking about our day and what we had on tap for tomorrow, laughing at each other’s stories about mutual friends, and just having a great time in each other’s company, as we usually did. It started to get dark, and there was a slight chill in the air, so we decided it was time to head home.

When we reached the house we continued gabbing, just enjoying each other's company. I asked RJ if she would like something to drink and she said that would be nice. Then she paused and said, “I've got something special hidden away in my room, why don't I break that out?”

I said that would be great and that I would get some glasses and she said that I should bring them up to her room so we could listen to some music, too.

I was carrying two ice-filled tumblers upstairs when I could hear water running in the bathroom through the half-opened door. I figured RJ was washing her hands or brushing her teeth, so I just went right to her room and set the glasses down on her desk. I plopped down on the bed to wait for her to finish, and called out to her asking where the goodies were so I could pour our drinks.

“In here, Nick. I've got them. Bring the glasses in.”

I grabbed our glasses and headed for the bathroom. As I pulled the door open the rest of the way and walked into the bathroom, just inside the door I came to a screeching stop.

RJ was leaning against the vanity stark naked.

“Surprise,” she said. I just stood there, open-mouthed, and eyes practically popping out. “Nick,” she said, “put the glasses down and come here. I thought I owed you for walking in on your shower before.”

I approached in a daze. I'm not sure but I think my tongue must have been hanging out, I know my cock was jumping to full mast at the sight of RJ's fantastic bod. I almost dropped the glasses trying to find the vanity top without taking my eyes off her. She reached over and took the glasses and set them down. Then she took my hands and placed them on her boobs, looking me in the eyes.

She had that smoky-eyed look that you read about in books, and her boobs were so warm and smooth that my fingers automatically started caressing them and tweaking her erect nipples. My fingers were chilled from holding the ice-filled glasses, remember.
She let me grope her for a few minutes, then she took me by the hand, and picking up her glass and handing me mine, she led me back into her room. I think I must have been squeezing my glass, because by the time we walked the four or five steps into her room, most of the ice in my glass had melted and the ice in RJ's glass was still frozen.

We were sitting on her bed, still holding hands when I suddenly realized what was happening. “RJ! We can't be doing this. It's wrong!” I said. My head was telling me it was wrong, but my little head was screaming “shut up you fool”.

“Nick, it is not incest. We are not brother and sister, except by marriage. Do you like what you see? You can't tell me you haven't been perving over me for a while, 'cause your cock is saying you have.” With that she reached down and stroked my raging hard-on through my pants. “Tell me, have you ever fucked anyone before? Or are you still a virgin like me?”

“I almost. . .no, I haven't ever gone all the way with anyone,” I admitted.

“I would like you to be my first,” she said, her voice was husky, and her breathing was becoming a bit ragged as she continued to rub my cock.

Now, I'm not a retard, but sometimes my brain has a hard time switching from What-The-Right-Thing-To-Do is to What-Is-The-Thing-I'm-Desperately-Wanting-To-Do. This was one of those times. “But why? Why do you want to (and I still can't believe I said this) lose your virginity now? And with me?”

“Part of the reason is what you just did. In spite of being so turned on, you are worried about me. And then there is that you have always looked out for me at school, and I remember more than once you took the blame for things I did, and you never tried to use it for your advantage later. And then there is the fact that you are hotter than hell, Nick. And finally, lots of people are convinced that I've been sleeping around, and we both know I haven't, so if I've got the name, may as well play the game.”

My brain was whirling around at warp-speed. Finally my hormones won out over my hesitation. I reached over and took one of RJ's pink nipples into my mouth and sucked it gently as my other hand began kneading her boob.

She began rubbing my neck and pulling me tight against her. I'm not sure who started moaning first, her or me, but we both were enjoying this. I let go of the nip I was sucking and gave its twin equal attention. Now both of her nipples were fully erect and turned a darker shade of reddish brown. Her aureoles were puckered and I could feel her boobs tightening as her passion increased.

She pushed me back on the bed, and her nipple slipped out of my mouth as she began unfastening my belt and tugging my zipper down. I lifted my hips so she could pull my pants down, and she grabbed my shorts and my pants and skinned them off me in one swoop, then RJ tugged me seni-upright and pulled my shirt over my head. Now we were both naked. Well, almost. I still had on my shoes and socks.

“Take those off, you. You're not going to need them,” she said, and began tracing her fingers from my chest across my stomach to my cock. The shoes thumped as I kicked them off and they landed half-way across the room. Getting my socks off was more complicated, and I had to twist and lift my legs to reach them. All the while RJ was teasing my cock with her fingers.

I grabbed her shoulders and flipped her over on her back, then began exploring her body with my own fingers; first circling her boobs with my hands and teasing her nipples with my lips and tongue. First one, then the other side. I began rolling her nipples between my thumbs and forefingers as I leaned into her to begin kissing her mouth and throat. I started gently sucking her throat, being careful not to leave a hicky—I was kissing her, not trying to brand her, after all.

RJ was clearly enjoying my attentions and she was rubbing her fingers all over my cock and cupping my balls in a constant stroking. I was getting even harder at her touch.

Finally I began kissing my way from her breasts down the front of her ribs, flicking my tongue as I went and then sucking and kissing. As I reached her navel, I stuck my tongue into her inny and she flinched. “That tickles,” she said.

I knew if I didn't slow RJ's stimulation of my cock real soon, I was going to cum in her hand in a minute or so. Reaching down, I pulled her hand off my cock and pressed her flat on the bed so I could work my way down to her pussy.

RJ's pussy was shaved, with just a neatly trimmed triangle above and leaving the lips of her pussy exposed. Her labia were fairly thick and tightly closed. I hadn't seen many pussies up this close, but RJ's was beautiful. I could detect the slight aroma of her arousal and I bent close. I wanted to admire this sexy wonder before me as much as I wanted to get inside it. I gently spread the lips apart and was faced with her thinner inner lips and her hooded clit. As I stroked the slit of her lips she began to breath in ragged breaths and a soft moan escaped. My lips were almost touching her inner lips, my breath warms and I could tell it was adding to her sensuous pleasure as I softly blew across her clit.

“Touch me, Nick, touch me there,” she moaned and she reached for my head to pull me to her pleasure.

I licked her labia, parting the lips with my tongue, then forced in deeper and licked up to her clit. The more I flicked my tongue, the more her clit peeked out of its hooded hiding place, and the more RJ began to squirm, moan, and breathe heavily. I continued for several more minutes and then took my index finger and began rubbing her pussy until my finger was slick with her juices. Then I slid my finger deep inside. Curling my finger I began caressing the roof of her pussy, stimulating her G-spot as I licked her thick clit.

Just a note here is in order. While I was a virgin, in the sense I had never fucked before, I was lucky enough to have had a couple of partners who taught me how to satisfy them short of fucking. Now I was using everything I had learned to please RJ.

I continued going down on RJ, tickling her G-spot, and tweaking one of her tits with my other hand for several minutes until she began to thrash about, letting out gasps and yelling, “Yes, yes, yes! That's it. Just like that,” and had a convulsive climax that seemed to last and last.

When she stopped quivering, she hugged me and kissed me long and soft. She was covered in sheen of sweat and she was still trying to get her breathing back to normal.
“Damn, where did you learn to do that? I thought you said you were a virgin, too.”

“I had a good teacher. She had self-serving reasons for being my mentor,”
I said. “But that is just the warm up; the main course is yet to come. And I mean for cum to be the word of the day,” I quipped. Then I kissed her long and slow with lots of tongue.

“My turn,” she said pulling free of my tongue and pushing me on my back. She began with light little kisses on my eyelids, and then a hard, deep kiss to my lips. Her hands began stroking my hair as she let her tongue rove around my mouth. Then she began to kiss my neck and chest, and murmuring that she could just eat me up.

“I definitely hope that is on the agenda,” I said as I began to rub along her sides, being sure to get as much of her boobs as I could.

RJ continued kissing down my stomach, at time sucking harder or nipping as she went. At one point she grabbed my nipples and tweaked them as she licked my stomach in long slow, wet licks. But I pulled her hands away saying No. She stopped what she was doing and said, “You don't like that?” And when I said I didn't like my nipples played with, she shook her head and said it was too bad because it felt so good when I did it to her.

I pulled her up so I could kiss her again, sliding my tongue deep in her mouth as I stroked her face with my palms. In the meantime, RJ's hands were busy stroking my sides and stomach in an attempt to get to my cock.

“Lie back and let me do this,” she whispered, and she slid down until she was poised over my groin. She took my cock into her hand and began stroking it. Then she bent down and kissed the tip. Next she began planting kisses down and around the shaft while her thumb and fingers griped the base of the shaft tightly. My cock was raring to go; it felt as if my erection got any bigger it would split like a ripe fruit.

I lay back and closed my eyes to enjoy this to the fullest. RJ's warm breath was coming in little bursts directly over my cock. Then she paused for a few seconds and I felt her hot, wet mouth slip over the helmet of my cock and her tongue tentatively lick the underside like she was tasting an ice cream cone. I held perfectly still so that I didn't push my cock into her mouth and cause her to gag. For an agonizing moment she did nothing, then she began sliding down my cock, pushing the foreskin back. Then she began sliding her lips back until I almost came out of her mouth before sliding back down just a pit farther. She was about a third of the way down before she started to gag.

I took her head in my hands and pulled her off my cock and bent to kiss her.

“I'm sorry, Nick. I've never sucked a cock before, and I want to please you like you did me.”

“Hey,” I whispered, “What you did was great. I don't want you to do anything you're not comfortable doing. Okay?” I stroked her face and hugged her. “Do you want to just cuddle for a while. It's okay if you do.”

She started to cry, and I thought I had done something wrong and offended her.

“I'm sorry, babe, I didn't mean to. . .”

“Oh, you didn't make me unhappy, Nick, I just love that you are so tender with me, so concerned about what pleases me. You are so. . .so damned sweet!” And she pulled my head down and fiercely kissed my lips. “But, if you think you're getting off with just this, you're mistaken, mister. You're going to fuck me until I can't walk straight.” And with that she popped up on her knees and grabbed my cock.

I was afraid for a moment that she was going to pull it off she was so energetic. But then she began stroking it until she was sure it was rock hard again. “Take me, Nick, fuck my brains out!” She was a woman possessed. She had that smoky look to her eyes.

“Okay, sweetheart, lie down and let me get on to business,” I said in my best Humphrey Bogart imitation. My best Bogart is not very good and RJ mock-groaned.

I began kissing her lips, and then her boobs and stomach, and on down her thighs and back up to her pussy lips. I spread her labia apart again, smelling the musky aroma of her pussy, still damp from her orgasm, and slowly began licking her inner lips and flicking the tip of my tongue against her swollen clit. She immediately began to moan and to reach for the back of my head. I continued licking slow then faster, then slower until her passion built. Then I slid my hand under her and began stroking from her wet pussy to her puckered rosebud asshole. When my finger was good and wet, I began to rub the outside of her asshole, lubricating her with her own juices. I continues tonguing her and then slowly began pushing my finger into her butt-hole, until I could feel her sphincter relaxing enough to admit my finger to the first joint. I stopped my movement and let her get used to the feel of something foreign in her ass. Then I began rubbing her in little twisting circles.

RJ was getting very turned on, thrusting her pussy toward my finger, trying to get more contact. I removed my finger tip from her ass and got to my knees, continuing to stroke her clit. Then I lifter her legs so they were across my thighs and pulled her into position so I could enter her. She scooted as close as she could get in anticipation of her deflowering. And I took my cock and inserted it to the moist lips of her pussy, and paused.

Slowly, I began rocking forward, pushing my cock further into her virgin pussy. I entered slowly, a little at a time. While I knew RJ was a virgin, and I was pretty sure she had already broken her hymen through her gymnastics, but just in case, I proceeded gently. I would penetrate a little bit then pull back until my cock was just inside her before going in a little deeper each thrust until I was fully sheathed in her pussy. I started making mini-thrusts, moving in and out a small amount until she was thoroughly wet and my cock was sliding without any resistance. I could feel the walls of her pussy griping my cock as it thrust in and out. She had fantastic muscle control. It felt like she was milking my cock.

“Omigod,” she cried, “you feel so good. It feels wonderful. Don't stop, please don't stop.” RJ pressed her hands into my back trying to force me deeper into her pussy.
I slowed my thrusts and slid my hands under her back so I could roll her over to ride on top. Once she was in position I began thrusting faster. In this position I was able to go deeper and could feel it when I bottomed out on her cervix. And with my hands on her hips I guided her into a good rhythm. It only took a minute or so before she began slamming on to my cock and began cumming, her head thrown back and almost screaming her passion. I could feel her pussy throbbing as she came and that triggered my balls to start their pre-ejaculation contractions.

“I'm going to cum,” I cried, trying to roll her off so I could withdraw. But RJ wouldn't move or let me out from under her. I don't know if she was just still in the throes of her orgasm and couldn't move, or if she wanted me to cum inside her. In either case, I felt my balls clench, the delicious feeling of the cum shooting up and out of my cock, and the warm splash of it filling RJ's hot pussy and bathing us in its thick wetness.

We lay there for several minutes, unable to move, talk, or think coherently, only able to cling together in post-coital euphoria. Finally RJ bent down and kissed me and sighed a languid sigh of utter contentment. “Omigod, that was fucking wonderful.” Then she laughed at her unintentional pun. “Are you sure you have never done this before?” she asked.

I shook my head.
