I'm the youngest girl (at a tender age of 18), my older sister Kimberly (whom I refer to as sissy) is the oldest, she's 23. Sissy and I have two stepbrothers, Nathan, 21, and Donald, 25- their dad married our mom when I was a newborn and nathan was pretty much and infant, Sissy and Donald remember their birth Father and Mother, although both were killed in a plane crash on the way to Texas. That's where our mom and their dad met- it was a most tragic incident that left us without a father and Nathan and Donald without a mother. We were all lucky to have survived that horrible crash and SO VERY lucky that our parents met and fell in love. Growing up the four of us have always been very close, mom and dad always bathed us together, let us sleep together do everything together... We have always been very loving of one another, and the boys have always protected us... Especially Nathan, he's always been so loving and so protecting of me, no one or nothing could ever harm me as long as there was a breath of air in Nathan's body. We didn't find out we weren't biological brothers and sisters until I was 18, that was when the decision was made. Our mother and father sat us down and told us that Nathan and Donald weren't our biological brothers, and that Dad, wasn't our biological Dad. At first I was devastated, I mean, my whole world to me at that point was somewhat of a lie... but on the same token, I was slightly relieved. For a few weeks, I'd been having a recurring dream about Nathan, I had been developing feelings that I felt weren't natural for a baby sister to feel for her big brother. I'd been very lonely, we'd moved to a new town about 200 miles from our old home, into a new area where dad was transferred... The home we lived in was huge, very beautiful, but very lonely at night when everyone was at work. I especially missed Nathan, he would always come into my room at night and talk to me to cheer me up, but now, he was working late, and I was longing for him. One night, I felt a strong urge, I needed Nathan, and not as a brother, but as my lover. Even thought he was only my "step" brother, he was raised as my brother... I didn't know what to do about the feelings I had, I would look in the mirror at myself, at a petite 5'4, and 135lbs, I looked pretty sharp, my big brown eyes looked so innocent as my long blonde hair fell over my tiny shoulders, my breasts, very large for my frame, a massive 38D were shown off very nicely in the little baby doll nightie I had on. I could just practically feel Nathan's big strong hands on them, caressing them... I would feel so secure if I had him to be my first. His large frame, a tall 6'4 and 235lbs, made quite a good sized man, and dark brown hair brought out his kind and loving blue eyes. I could just see those baby blues looking into mine as he enters me, taking my little cherry from me... OH that was too much I though, I feeling my little virgin pussy getting wet... So unsure as to what to do about or with Nathan, I go to my wise Sissy's room for advise... As I'm walking down the hall I hear moaning coming from her room, I peek into the darkness and see Donald on top of her, his lips wrapped around her hard nipples, licking and sucking them so hard... "Ohhhhhhhh yes Donald, ohhhhhhhh that's it brother" Sissy moaned with pleasure. My eyes became a big a silver dollar as I saw his monstrous cock... it must've been a good 9" if not bigger, and SOOOOOO thick, I looked down at Sissy's tiny shaven pussy as he entered it. It apparently wasn't their first time having sex with one another, as Sissy took his cock all the way in, moaning with pleasure the whole time. I watched them for a few moments, seeing how gentle and loving he was with her, but at the same time a little rough and aggressive. "Ohhhhhhh harder Donald, harder" Sissy would moan out as Donald thrust in and out of her tiny hole harder and harder... "Cum for me Kimmy, give me your sweet juice baby, give me all you've got" I heard Donald moan as he pounded into her pussy. That was all I could stand to see, I was so hot and horny. I had to cum, and I had to cum quick. I quietly snuck back into my bedroom where I turned out my nightlight and began to rub my swollen nipples. "Ohhhhhhhh" I moaned out softly, pretending my hands were Nathan's ... soon my tiny fingers wandered to my dripping wet pussy, feeling the smooth shaven skin, I rubbed my pouty lips, feeling all of my sweet spunk on them... "Ohhhhhhhh yes" I moaned out a little louder as my finger found my clit, I rubbed it fast and hard, pretending it was Nathan's tongue, licking and sucking on my swollen clit... "Ohhhhhhh Nathan" I moaned out as I started cumming hard, my sweet juices flowing from my wet pussy. As my orgasm subsided, and my breathing went back to normal, I laid back to go to sleep, dreaming of my true love... my loving brother Nathan. Little did I know, that Nathan had arrived home from work early, and had come by to tell me good-night, and saw the WHOLE entire thing. As I slept, I felt a hand running down my back, I turned over, smiling sweetly "Nathan, what... what are you doing?" I asked innocently as I turned over onto my back, watching Nathan as he looked at my voluptuous body in the small white nightie. "I came to tell my baby good-night like I always do," He said as he leaned over to give me a big hug, only tonight, this hug lingered for awhile... Could he have the same feelings I do? I think to myself, or is it my hard nipples poking into his chest that's making him hold me longer than usual..."I missed you tonight baby" Nathan says softly, kissing my cheek. I missed you too big brother, a whole, whole lot... I say, pulling him down onto the bed as he kisses my lips very gently, yet innocently, like every other night. We look at one another, without a word being said, Nathan looks down at my nipples and reaches his hand out to caress them... "What...What are you doing brother?" I ask somewhat startled. "Something I should've done along time ago baby sister... show you how much big brother really loves you" Nathan said as he moved his lips to mine, parting them, kissing me deeply as his strong hands caressed my breasts firmly, feeling my hard nipples pressing into the palm of his hand. I couldn't believe it, it was finally happening, I was going to make love to Nathan. I felt him spreading my little legs as he slid in between them rubbing his hard cock over my swollen wet lips..."Ohhhhhhhh " I shuddered as I felt his cock hit my clit, soaking his boxers with my juice... soon his head moved down to my nipple, licking it teasingly, driving me CRAZY..."Ohhhhhhh yes brother, ohhhhhhhhh yes, that feels soooooo good" I moaned with pleasure, holding his head to my nipple... I nearly pass out as I feel his big fingers parting my tiny pussy lips, sliding one inside of me deep..."You're so wet and tight baby...all for your big brother" Nathan moaned, as he watched his finger fucking my sweet pussy. I cooed and moaned with pleasure, moving my hips up to meet his finger as it thrust into my tight little hole. "Do you want another one baby, do you want brother to finger you really good?" Nathan said seductively as he positioned two fingers together pushing them into me, rubbing against my g-spot. "Ohhhhhhhhhh Brother! Ohhhhhhhhh rub me there...harder... Ohhhhhhhhh that feels sooooooo good" I moaned out, gripping onto his shoulders tightly as my hips bucked and pussy spasmed..."Ohhhhhhhhh brother...I'm...I'm...Ohhhhhhhhhhh". "That's it baby, cum for big brother, show him how good he's loving you baby, show me..." Nathan moaned out, fingering me as fast and deep as he could. I came with such force that my pussy juice was dripping everywhere, coating Nathan's fingers and wetting my bed good. "Ohhhhhhh Brother, ohhhhhhhhhh yes" I moaned, closing my eyes tightly, gripping onto him with everything in me as my orgasm subsided...I opened my eyes and looked up at him, knowing what he wanted...exactly what I needed: To make love. "I love you baby" Nathan whispered to me as he slid his boxers off, taking my hand and wrapping it around his huge cock...big cocks must run in the family I thought, his cock was a good 8" or 81/2 inches, very close to my oldest brother, Donald. I began to stroke brother's cock lovingly as he moaned... slowly he leaned back a little. "Spread your legs for brother, baby," he said as he looked lovingly down at me... I spread my legs for him letting him get a good look at my tiny little virgin pussy... "Please be gentle brother, I...I'm still a virgin" I said so nervously, my voice cracking slightly. Nathan leaned over and kissed me softly, reassuring me that everything would be ok..."I'll be gentle baby, I won't hurt my angel" Nathan said softly as I felt the head of his enormous cock enter my tiny little lips. "Ummmmmm" I moaned feeling the soft head just inside my little pussy...that was the end of the pleasure for the moment. Nathan's cock was so huge, and my tiny pussy so small, I thought I'd never take him in all the way. "It hurts big brother... it hurts really bad" I whimpered, looking up at him with tears welling up in my eyes. "It's ok baby, it's gonna hurt for just a second more, then it'll start feeling good I promise... Here baby, wrap your arms around big brother tight and kiss me, I'm getting ready to make you into a woman"... and with that his lips met mine and POP! There went my maidenhood, my big brother had taken my virginity. Nathan kissed me deeply as his cock entered me fully... I have no idea how my tiny little pussy stretched to take it all the way in, but somehow it did. I took him all the way inside of me and after a few moments the pain began to die and pleasure took over... I felt my pussy starting to become more lubricated enabling him to slide in and out of me with such ease... "Ohhhhhhhh yes brother, ohhhhhhhhhh your cock feels sooooooo good big brother" I moaned out with pleasure, running my fingers teasingly up and down his back as his thrusts became harder...nearly making me cum all over myself again. "Ohhhhhhhh damn baby, you're pussy's so tight, ohhhhhhhh it's soooooooo good baby, sooooooooo good" Nathan moaned as he leaned down to kiss me, feeling his tounge in my mouth as his body hit my clit sent waves of pleasure throughout my entire body... "Ohhhhhhhh Nathan, I'm cumming, I'm cumming big brother, ohhhhhhhhhhh yes...Ohhhhhhhhh" I moaned as my hips rose to meet his every thrust as my sweet juices covered his cock..."Mandy, baby, ohhhhhhhhhh baby sis, ohhhhhhhhhhhhhh I...I... I can't hold back Mandy"... Nathan moaned as he pounded his cock into my pussy, harder and harder, as deep as I could take him, I grabbed onto his shoulders tightly and held him as he started to cum..."Mandy, ohhhhhhhhhhhhhh baby, I'm cumming, I'm cumming for you baby sister, ohhhhhhhhhh" Nathan moaned as his giant cum fill balls emptied into my virgin pussy, filling me completely... "I love you big brother" I moan softly as he colapses onto my chest, still deep inside of me. "I love you too my precious baby sister...no one will ever love you like your brother does" Nathan whispered softly as he tenderly kissed my lips, turning over and opening his arms to hold me. I lay my head against his chest as he wraps his big strong arms around me, kissing my forehead. "I'll always love you Mandy" he says pulling me in close. "I'll always love you too big brother, more than anyone... I don't want another man...only you..." I say looking up at him, smiling so sweetly. "I have a confession to make brother". "What's that baby?" Nathan asks inquisitively. "Tonight when I saw Sissy and Donald making love, I... I was going to ask her what I should do... about you... I... I have been in love with you for sometime now, only didn't know what to do... and I thought for sure Sissy could help me... and even though I didn't get to talk to her, she did help me..." I say kissing your lips softly. "So seeing Donald making love to her made you see that if we made love it would be ok too?" Nathan replied as he stroked my face gently. "Uh-huh" nodding my head yes. "Baby, promise me, you'll let me be your only love, I'll be good to you and take care of you...no one will ever love you like your brother" Nathan says lovingly as he caresses my arm. "I promise big brother, as long as you promise to love and take care of me forever, I am yours to love and to make love to whenever you do so desire". And with that Nathan and I became lovers... there is much more to our story, this is only the first chapter...Please write to me and let me know what you like of this story and if you would like to see more... Sweet Baby Sister Amanda Ch. 2 *I want to say a big thank you to EVERYONE who has posted feedback for me... I appreciate it so much and would LOVE to be able to respond to each and every one of you, unfortunately I get so much, it is impossible- remember, Mandy Loves you ALL!* A short time has passed since my first night of passion with Nathan. I'm beginning to feel sick every morning. I've been throwing up a lot. I went to the drug store yesterday to get a pregnancy test. I feel so scared. I don't know how Nathan will react to a baby. I know he loves me- I know we're going to get married- but a baby- now? "Am I ready for this?" I think to myself as I look in the mirror. Standing in the middle of my room totally nude- my perky breasts standing at full attention, my long blonde hair flowing down my back- and my stomach that was once flat, now has a slight bulge in it. "There's no need to take that test," I think to myself. "You're already pregnant Mandy, just deal with it," I say softly on my way to the bathroom. My hands shake nervously as I open the package. "I've never taken one of these things before," I say to myself as I rip open the "stick. " "Hold in urine for 1 full minute," I read aloud. Taking a deep breath, I begin my test. Placing the lid back on the tip, I wait nervously for a result. "One line not pregnant, two lines pregnant," I say to myself as I watch the lines starting to appear. Small tears well in my eyes as the second line appears. "There's no denying it now Mandy- you're pregnant," I say to myself, rubbing my belly as I look in the mirror. "How am I going to tell Nathan- what will Mom and Dad say?" all of these questions race through my head as I begin to cry. I walk down the stairs, sitting on the couch. "It's 5:30pm, Nathan should be home from the office soon- how are you going to tell him Mandy? How are you going to tell him?" I think to myself as tears roll down my face. I hear the car pull in, Nathan opens the front door walking into the living room. I turn my head to look at him, my eyes all puffy and swollen. "Hi Brother," I say softly. "Oh, Mandy, what's wrong baby? What's wrong?" Nathan says as he walks to the couch, sitting down to hold me. "You can tell me angel, whatever it is, you can tell me," he says softly, running his fingers up and down my back. "Nathan, I don't know how to tell you this... I... I just don't know," I say sobbing as I lay my head on his shoulder. "Just tell me angel, whatever it is, we can handle it together. I love you Mandy, whatever it is, I'm here for you," Nathan says as he takes my face in his hands, looking straight into my eyes. "Nathan, I'm pregnant," I say softly- awaiting his reaction. "Pregnant?" he replies softly, smiling at me. "You... you aren't mad?" I ask a little surprised. "Why would I be mad Mandy? I made that baby, I did that to you, how could I be mad? How could I be angry at the woman who is carrying my child?" he said calmly, kissing my lips tenderly. "Oh Nathan, I love you so much. I'm so scared. I'm so young... and what... what will mom and dad say?" I ask nervously. "Well, the worst part is over with," Nathan says as he gets up, unbuttoning his shirt and taking off his tie. "What do you mean, the worst part?" "Mom and Dad know Amanda. I told them last night. I phoned Dad in England. He was very excited about closing the deal with the company over there. I figured what better time? He was up so high, I figured nothing could bring him down- not even us. I was right. He was in shock for awhile. Mom broke down into tears on the phone-" "Oh Nathan, how could we hurt them like that," I say beginning to cry again. "Shhhhhh, it's ok Mandy. After awhile, they told me that they honestly expected this to come about. They knew that when they married years ago, that the four of us would never have a "normal" brother/sister relationship. They knew about Kimberly and Donald before we did. " "Are you kidding me? No way!" I said completely surprised. "Yes, they knew, and they knew about us too. They knew before the night I took your virginity. It just upset them because you're the baby. You're the little princess in our family. It doesn't matter that you're a grown adult now- in their eyes you're still the baby. And now that big brother has taken you- well you're no longer that sweet lil' innocent virgin you once were. " "I see," I replied softly. "You know, I never thought of it that way. " "You wouldn't Mandy, neither would I. I guess it's just a parent thing. We'll be learning about that soon enough," Heath replies pulling me to my feet, rubbing my belly. "Hello little one, Daddy's home," Nathan says sweetly as he kisses my belly. "I'm going to go show Mommy how much Daddy loves her," Nathan says with a smirk as he lifts me to my feet, carrying me to our bedroom. I moan softly as he lays me down. His big strong hands removing my tiny gown, just as he has so many nights before- but tonight, it's different. Tonight, there's a baby inside of me- and we both know it. My nipples become fully erect as the cool air of the room hits them. "Just think, pretty soon these will be full of milk for Daddy to suck from them," Nathan says teasingly as he locks his lips over one. "Ohhhhhhhhh Brother... ohhhhhhhhh that feels sooooo good," I moan, gently holding his head to my breast. I feel him caressing the other breast as he sucks my nipple. Teasing it with his tounge- making my pussy dripping wet. "Ohhhhhhh Nathan, finger me... I'm so wet for you," I moan loudly, feeling his big strong hands parting my small thighs. I feel his fingers teasing my shaven, moist slit. One, then two fingers slide deep into my pussy. "You're VERY wet for me tonight baby sister," Nathan says with a smile, kissing me deeply before his lips travel down my body. His kisses tease my breasts, moving to my belly. He kisses it tenderly as he looks up into my eyes. His lips move down further until they are locked on the sweet lips of my pussy. "Ohhhhhhhhhh Nathan... yes brother, yes... ," I moan softly, closing my eyes as he spreads my sweet lil' lips, licking softly at my clit. My head rolls from side to side with pleasure. "Ohhhhhh Nathan, yes darling, yes... lick me good- lick your angel sooooo good," I moan, screaming in ecstacy as he sucks my clit, his fingers still buried deep inside my aching pussy. "Cum for me Mandy... show brother how much you love him, show him how much you want his cock. Show me Mandy," Nathan moaned loudly as he fingered me harder, licking and sucking my clit soooooo good I nearly passed out. "Ohhhhhhhhh Nathan, yes Nathan, yes... Brother... Ohhhhhhhhh, ohhhhhhhhh," I moan, rolling my nipples between my fingers, head rolling from side to side on the pillows, my pussy clamping down on his fingers as I cum so hard on them- coating his tounge with my sweet juices. "Ohhhhhhh Nathan... Nathan... ," I moan softly, panting for air as he moves to my side, his aching cock poking into my hip. I reach over, taking it in my hands, stroking it gently. He kisses my lips deeply, I can taste my sweet juices on his lips. "Can I suck you brother? I want to show you how much I want you," I say teasingly, stroking his cock VERY gently. "Mandy, you're gonna make me cum before I even get inside of you," he replies moaning. Without hesitation, I move my lips to his cock. Taking only the head in. Slowly, I move my lips down to the base of his cock- taking him fully into my throat. "Ohhhhhhhh Mandy... ," Nathan moans, running his fingers through my hair. I reach down, caressing his balls gently as I start to pump his cock in and out of my mouth. I am only able to pleasure him a short time. "Mandy, you've gotta stop, I don't want to cum right now. I've been waiting to have your sweet pussy all day long," he says panting, moving me from his cock and laying me on my back. "Are you ready angel? Are you ready for brother's cock?" he asks as he thrusts hard and deep into my sweet pussy. "Ohhhhhhhhhh Nathan, yes... ," I moan softly, closing my eyes, gripping onto his big strong shoulders as he begins to pump my aching pussy. His strokes are long and hard, pounding deep into me. My breasts bounce around, I hold them up for Nathan to suck as he pumps me. I know it won't be long now, I can feel him starting to tighten up inside of me. "Ohhhhhhhhh Mandy, baby I can't hold on much longer," Nathan moans, screaming as he cums so hard, deep inside of my pussy. I feel him shoot, one, two, three loads deep in my tiny pussy. "Ohhhhhhhh Nathan, ohhhhhhhh brother... yes... cum for me... cum for your angel," I moan softly, holding onto his body as he colapses atop me. We lay there, as one, for what seems like an eternity before he rolls over to my side. "Come here baby, let brother hold you," Nathan says, patting his chest, wanting to hold me. "I love you so much Nathan... I love our baby... I'm so lucky to have you big brother," I say softly, kissing his chest as he holds me. "And I love you too my precious angel. I love the life we have growing inside of you. I am the one who is truly lucky," he replies, leaning down to kiss me. He holds me close as we drift off to sleep- visions of our us with our baby float through my dreams as I sleep next to the one I love...
