How I Became My StepBrother's Slut

"That's okay, sis, I am too." Brandon replied in a soothing voice as he reached over and cupped my free breast. I couldn't help but moan as he squeezed me with his fingers. I was flustered now. I was out of control, naked, horny and totally under the control of my equally naked stepbrother who was about to fuck me. I'd been curious about sex for the longest time, but I never dreamed my first time would be like this. Still, I couldn't deny I'd wanted to try it out, but I'd just never met the right guy before and now I wasn't left with a choice.

I continued to play with myself shamelessly as he ran his hands over me, exploring everything I had. What really surprised me was just how good it all felt, especially Brandon's roaming hands. His fingers just lit sparks all across me as they danced. I was busy on my own hot spots as well, stoking the fires that were raging through me now. This went on until I felt myself really leaking from between my legs.

"I'm ready, Brandon. Nice and wet." I whimpered and spread my legs as wide as I could. The words just forced themselves from my mouth, like they were programmed into me. I suppose they were, part of whatever Brandon had done to me. My thoughts were focusing on what was about to happen though. I was about to feel a man inside me for the first time, and that was important regardless of how it happened.

Brandon didn't waste any time. He rolled over and on top of me, hovering just above me. I looked down between us and spotted his hardness waving from his crotch. With one hand still working my clit, I wrapped my other one around his shaft and quivered. He felt so big, I could hardly believe he could fit inside me, though I felt the need to try just burning into me.

"Please, Brandon," I whimpered, the last of my strength going into the plea. I wasn't even sure what I was asking for. I wanted him to stop, but I needed to feel that shaft filling the sudden emptiness between my legs.

"Shh, sis, you'll love it." Brandon whispered and lowered himself enough so the head of his member was pressing between my legs. I pulled on it, and shifted myself until I felt his knob parting my slit. I couldn't believe I actually had a guys cock between my legs and felt a new rush of lust coursed through me. I still wondered how he was going to fit, then I realized what all my juices were for and started rubbing the head of his shaft between my dripping lips.

"What are you doing, sis?" Brandon asked, seeming to be genuinely surprised by my handling of his cock. I was too a little, but everything had just overwhelmed me. I couldn't get away, so I was going to be sure to enjoy this.

"Just getting you ready," I moaned. It was actually kind of fun rubbing my slit with his cock and it felt just amazing having him touching my forbidden flesh. I worried for a moment that I wasn't getting him wet enough and had another idea. "Come in a little closer and hump my pussy lips a little, so we can get you all lubed up."

Brandon didn't need to be coaxed any more and I gasped as he slid his length across my slick lower lips. I wrapped my hand around him and helped spread my juices all over his length until he was nice and slick. I humped him back a little too, savoring the intimate touch we were sharing. I knew we were ready now and I looked up at Brandon again.

I still couldn't believe I was looking up into the eyes of my first lover as I shuddered beneath him. My earlier objections had all fallen away, I didn't forget them, or that I was in this position because of Brandon, but he'd stoked the passion within me and all I wanted was to indulge it now. Tomorrow I might regret it, but right now I was aching for him and I let him know.

"I'm ready, Brandon." I smiled as I gave his cock a nice squeeze. He smiled down at me and lifted his hips up again. I didn't miss a beat, and guided him right back to my slit as he moved into position to take me. I rubbed his head against my fold, this time seeking the entrance to my pussy for him. I shuddered at the feeling of my lower lips being parted again, but concentrated on the task until I felt him slip deeper into me. I gasped at the sudden fullness at the entrance to my passage. This was it, he was in position and I looked up.

"Are you sure you want this, sis?" Brandon asked. For a moment I really believed he meant it, that I could back out even after all this. It didn't matter now, I was too far gone, no matter how I'd found myself here, there wasn't anything I wanted more than to feel his cock all the way inside me.

"Take me." I insisted with every ounce of sincerity in me. Then he lowered himself onto me completely, pressed his chest to mine, and kissed me deeply. Our lips touched with their own fire and I was kissing him back as hard as I could. I wrapped my arms around him and ran my hands across his back as he rubbed my sides.

Then just as our tongues slipped through I felt him push his hips forward and moaned in shock as I felt my stepbrother's cock sinking into me. I shuddered at a sudden tearing feeling deep inside me and realized I had just become a woman. The feeling of his sack between my legs surprised me a moment later. He was all the way inside me with one wonderful thrust and I was amazed at the unreal fullness from being filled with his shaft.

Brandon started to pull back a moment later and I flinched. It hadn't hurt so much going in, but I was sore. I shot my legs up around his hips and held him in place, so he'd leave his nice big cock all the way up inside me until I was ready for more.

"Are you okay, sis?" He asked with honest worry. I'm sure he'd heard stories about a girl's first time, though it surprised me for a moment that he actually seemed concerned after all he'd done.

"Yeah, just don't move, I'm just a little sore." I smiled, not wanting to worry him for some reason.

"You feel so nice, sis. You're just perfectly warm and tight. How do I feel in there?" Brandon asked. His curiosity getting the better of him, but I was still compelled to answer his questions, not that I really minded.

"Big!" I giggled. "I feel so full down there like you're just splitting me open, but it's wonderful, Brandon. Thank you."

I lifted myself up and kissed him again. We stayed like that for a couple minutes, locked together as intimately as a boy and girl could get while I adjusted to my new womanhood. Our hands took liberties as well while our tongues danced, and I don't think there was a part of either of us that didn't get played with by roaming hands.

"Okay." I whimpered, pulling away from his lips. It felt wonderful having him inside me, but I wanted more. Even though I still felt a little tender, I knew it was time for what came next.

Brandon just smiled again and pulled himself slowly out of me. I squirmed under him as I felt his cock moving inside me. Nothing had ever prepared me for such a wonderfully strange feeling. Then just as he almost pulled out of me I pulled him in with my legs and thrust up my hips, squealing with delight as I felt his shaft spread me open again.

"Oh, Brandon, do that again." I moaned as I ground my hips against him. He didn't need to be asked and quickly started a slow pumping rhythm into me. I just whimpered and squirmed under him totally enveloped in the sensations he was stroking in me.

"You like this, sis?" Brandon asked as he plunged into me again. I shuddered as I felt the knob of his shaft parting my folds again all the way to my very center. It was more amazing than I could ever have dreamed.

"Yes, it's wonderful, Brandon. Can you do it harder?" I asked, somehow knowing that the pleasures he was striking inside me were only the beginning.

"Like this?" He asked then proceeded to pound into me with harder strokes. I felt my breasts quiver each time he bottomed out inside me and heard the slap of his flesh on mine. I knew instantly that this was what fucking was meant to be.

"Oh, yes, just like that!" I grunted with him as he kept pumping into me. I was humping back against him as hard as I could as well, and squeezing down on his cock with all my strength. He groaned in approval and it wasn't long before we were simply thrusting into each other in a beautiful primal rhythm.

His every thrust seemed to just edge me higher as well, and I was awash in the sensations of making love. Our bodies were writhing together, and my breasts jiggled against his chest as he pounded into me, my hard little nipples tracing patterns on him with every bounce. We kissed passionately as well, only stopping to catch our breath.

It seemed a wonderful eternity was spent like that, merged together so perfectly. Then I felt Brandon stirring even more inside me, our thrusts were sharper, harder, more urgent. The fire inside me was a blazing inferno centered on his wonderful thrusts and then I felt it. My eyes flew open, looking inside as something inside me tore open and consumed me in a wonderful torrent. I tensed around Brandon, and shook with pleasure echoing through my entire being, and I let out a soulful cry of joy.

"Get ready for it," Brandon grunted as he kept his wonderful thrusts going. I was too engulfed in my own pleasure to wonder what he meant until he gave me one hard thrust and held himself deep inside me. Then I felt his member pulsing inside me and a strange warmth fill my depths as he let out a deep moan of satisfaction. I realized he was coming inside me and giggle again as I concentrated between my legs and tried to milk him with my pussy.

"Oh, sis, that's nice." He closed his eyes and moaned as I coaxed the last drops from him. He bent down and kissed me again, and we frenched for another couple of minutes.

"I'm sorry." Brandon finally said as we both came down from our orgasmic highs. He looked genuinely upset as he looked right into my eyes. It took me a moment to realize what he was talking about and I could help but giggle.

"I'm on the pill silly." I laughed. This was one time I was glad my mother was over protective. I hadn't been very willing when she'd suggested the idea when I'd hit puberty, but she'd insisted. Girls might not want to plan for sex, she'd said, but she didn't want to be a grandmother because I wanted to play innocent. Of course, even with that, she was plenty careful to steer me away from sex when she could, if she only knew what was going on upstairs right now, I smiled.

Brandon just laughed at that and rolled gently off me. I cuddled up to him and we just lay there like that and basked the afterglow for a bit. I could hardly believe I'd just been fucked, or how wonderful it had been. I understood a lot more about the world right then, but just let myself enjoy snuggling up against my stepbrother. I was so comfortable I hardly felt myself drift off to sleep as my fatigue caught up with me and I closed my eyes in Brandon's arms.

***

Waking up naked in my stepbrother's arms was about the weirdest thing I had ever experienced. I was lying with my back against his chest and his arm draped over my waist. I squirmed for a moment, not knowing what to do and remembering just how I'd ended up in that position. Brandon must have felt me squirm because he reached up, grabbed onto one of my breasts, and squeezed it firmly.

"Good morning, sis." Brandon sounded just like he was greeting me at breakfast, as if it was perfectly normal being in bed with me.

"Get off." I whimpered. "You may have had your way with me last night, but this has got to stop, Brandon."

"Come on, sis, I know you loved it last night and it's not like you have a choice." Brandon replied, not even pausing with his hand. I could feel my nipples getting nice and hard from his touch, and even my pussy was beginning to stir again. I had to admit, he really did know how to play with a girl.

"Please, Brandon, just let me up." I whined, hoping that I could convince him to let me go before he got other ideas.

"Great idea, sis. I'd love to have you ride me, just let me toss off these covers and you can hop on." Brandon laughed and quickly prepared himself. I felt a sudden surge of need inside me, getting myself ready for him. I wasn't going to give into him this time though. No way was I just going to be at his beck and call no matter how good it might have felt.

Of course that lasted about as long as it took Brandon to pull the sheets off of us and roll onto his back. One look between his legs and I just had to feel him inside me again. I quickly sat up and straddled him, putting my pussy right over his crotch and reaching between us for his already hard shaft. It wasn't until I pushed down and guided his knob to my entrance that I even realized what I was doing.

"Brandon, you've got to stop this." I moaned as I started to lower myself onto him and felt his member slowly spear me. "I'm not just some toy for you to play with."

I closed my eyes as I seated myself on top of him, not being able to fight back my moans of pleasure. I was still coherent, though, and I didn't want to be doing this no matter how wonderful it felt.

"Come on, Sis. You can't tell me you don't like this." Brandon smiled as he reached up and squeezed both of my breasts. I couldn't help but squeal with delight at his touch. I couldn't understand it, but even this light fondling was just amazing and I couldn't help but thrust my chest into his hands so he could play with me better.

"Brandon, please, you made me love it!" I objected with as much strength as I could given I was moaning from all the intimate sensations suddenly coursing through me. It was wonderful, every bit of it, except for the fact that I wanted to be getting ready for my Saturday and not playing sex slave for my step brother.

"And is that so bad?" Brandon asked while he gave each of my nipples a wonderful pinch. I gasped with delight, then scowled at him.

"I don't want to be some toy for you, you pervert!" I yelled back. Of course I was also rippling my pussy over his wonderfully filling shaft as I said this. This wasn't going well, everything was just deliriously wonderful, and I think Brandon was starting to get off on my objections even as I started to fuck him.

"Just think, Sis, do you really want to stop?" Brandon asked. Just like last night, I could almost feel that the question was genuine, like he was really giving me a choice. As I looked down at him and started to respond, he grabbed me by my hips and held me still.

"Think about it, Sis. Give it a minute." Brandon said. I wanted to shoot back at him that I didn't need a minute, but I couldn't. His blasted suggestions were just like orders to me, so all I could do was sit for a minute and think about.

He was kind enough to give me the time too. So I just sat there, straddling my stepbrother's cock, completely naked, contemplating whether I wanted to go on like this. I didn't want to be Brandon's little sex slave, but I couldn't deny that I'd enjoyed everything he'd done so far, aside from not asking permission. The weird thing was that I didn't want to really think about giving this up completely, it had been fun, I just didn't want to be controlled.

"So, sis, what'll it be? Do you want to be able to enjoy this every day or not?" Brandon asked, taking his hands away from my hips with a long caress down my thighs. That scared me, I just felt that he was threatening me somehow. I didn't know quite what he had in mind, but I felt like it was big. Strangely, the idea of doing this every day had its own appeal as well. Finally, I came to my decision.

"We can discuss terms later, let's just enjoy this now, okay?" I whimpered and started rippling my pussy again and humped him a little. I had the feeling Brandon was hoping to work me into a trap, and I just wanted to be dressed and not impaled on his cock when we discussed our relationship further.

"Okay, sis, whatever you say." Brandon smiled and I squealed as he gave me a nice couple of thrusts from below. I wiggled my rear on him and pulled his hands back up to my chest. I giggled as he squeezed me and then started humping him. It was different being the one doing the work, but it still felt good having his cock sliding into me and I angled myself so I could tickle my little nub while I humped him.

Just as I was beginning to get up a good rhythm we heard a knock at the door and I slammed myself down on Brandon in shock.

"Brandon, is Terri in there with you? You two should be getting down for breakfast you know." I heard mom asking from the other side of the door. I was scared stupid, afraid that mom would actually come in and see me fucking my stepbrother. It took me a moment to realize that Brandon didn't seem the least bit concerned. In fact, he was still happily fondling my breasts and had taken to humping into me as best he could.

"Yeah, Mom, Terri's in here. We'll be down soon." Brandon replied. He smiled up wickedly at me and whispered. "Come on, sis, you can hump and talk with Mom at the same time."

I didn't miss his meaning, and started fucking him again, with a slightly slower and quieter motion though. I didn't really want to, but I just had to be humping him before I could talk to mom. Then I gave my reply. "We'll be done really soon, Mom."

"Okay, kids, don't be too long." Mom replied, and I heard her walk away from the door. As my fear lifted I could feel the adrenaline still rushing through me. I realized I was really hot now and I just couldn't get enough action humping Brandon.

"Brandon, can you get on top now?" I asked, though I didn't slow myself down yet.

"Sure, sis, why?" Brandon asked. I knew instantly that he wasn't just going to roll over, he wanted me to tell him. Of course, I knew I couldn't keep myself from telling him as soon as he asked.

"I just really need it nice and hard and I can't do it like this." I replied humping him as hard as I could to prove my point. Brandon grunted his approval at my actions and smiled.

Then he just reached up and grabbed me, pulling me down to his chest. He locked his lips on mine and I couldn't help but slip him my tongue. As our mouths did that little dance, Brandon gave us a swift roll and I found myself beneath him, my legs perfectly spread and my pussy deliciously full. Brandon pulled away from our kiss and repositioned himself a little.

"Oh, god, Brandon, fuck me hard, just like last night!" I cried out, squirming my deeply impaled passage against him eagerly. I really needed it just like that right now, I was so hot and I knew only a good hard fucking could help.

"Wow, sis, almost getting caught has really got you going. I'm going to have to remember this." Brandon chuckled as he started thrusting into me. I really didn't care what he said, all I wanted was to work off this tension with his amazing shaft pounding me.

He didn't make me wait, in fact, I think he was just as turned on by the whole thing as I had been and he was giving me perfect hard thrusts almost as soon as he started. I did my best to meet him half way and we made wonderful music together like that. For another short eternity, we were one, locked in pure passion and all my concerns for how I got here fell away. I was a woman, he was a man, and that was all that mattered.

Of course, we didn't last very long, all that tension had already thrown me to the edge and our pace had done its work on Brandon. It wasn't very long before we both quaked with the pinnacle of our joining and we threw ourselves together with unrestrained power. Then I felt the damn burst and I fell back in blissful oblivion as a flood of pleasure coursed through me. Distantly, I could feel myself pull Brandon hard against me and felt his shaft plow deeply into me and begin to fill me with his seed once more.

I coasted back from that wonderful orgasm with Brandon's shaft still twitching inside me. He'd gotten me again I mused. Not quite finding the strength to be properly upset with him. He had been a good fuck I thought. A moment later I giggled at the reality that he'd been my only fuck so far, but I couldn't deny that I'd loved it. I wondered about that for a moment, was this really how I felt or just another of Brandon's little controls? Everything I'd done since last night had all seemed like what I wanted, or needed when I did it. Sometimes I realized it wasn't what I really wanted to do, but I couldn't stop myself and looking back now, I wondered even more which things had been my choices and which his.
