Being My Stepbrother's Slut Ch. 01

How I Became My Stepbrother's Slut: The New Adventures

Author's note:

The following is a work of fiction and a sequel to a previous story on Literotica called How I Became My Stepbrother's Slut written by the author, Farleven. He has given me his express permission to create a derivation of his works, and they are excellent contributions to our beloved website. We're lucky to have them, and I would encourage you to read them.

This is an authorized non-canon extension of How I Became my Stepbrother's Slut. If he wishes, Farleven may add to his original story and take it in a different direction, in which case, the two universes will become separate.

All characters participating in sexual activities are 18 years old or older. If you are not 18, or are averse to reading erotica, stop reading now.

This story contains scenes of stepbrother and stepsister sex, threesomes, and even foursomes! It's a pretty quick stroke-story, but I do hope it entertains and satisfies. Enjoy!

It had been three weeks since my stepbrother, Brandon, used his new uncanny-and sometimes even horrifying-abilities on me and my best friend, Susan. Those incredible abilities could affect a person's mind and even alter their bodies on a whim. It was as if he were gaining the powers of "The Q" from Star Trek, and I must admit, if it grew to that, the prospect excited and terrified me at the same time.

For now, he was content with altering people's minds and bodies, including himself. In one night, he had gone from an awkward teenager to a hunk with abs! Before, he was a little shorter, slightly chubby, with messy, short, black hair and glasses. Now he was about my height, the chubbiness had been replaced with a runner's physique, and he got rid of the glasses. I suppose he corrected his eyesight, but he kept the messy short hair.

As for myself, I was an 18-year-old high school senior like Brandon. I was about five-ten with sandy-brown hair. I wore it with a part that went down to my shoulder-blades, and sometimes kept it in a braid or ponytail. I had a slim figure I gained from my days on the swim team, and while my bust size used to be a modest b-cup, that changed one fine day.

Brandon had altered my mind to find him attractive, though that wasn't much of a stretch given his new body. My new bust came to me one morning when he was gloriously pistoning his cock in and out of my pussy from behind while my hands were on the table and my skirt was hiked up to my hips. As I felt his delicious cock going in and out of my cunt, I felt two things. One was that his cock was growing larger and wider while nestled in my love tunnel, and my tits grew to a double d!

Every woman wonders what they would look like with a bigger chest, but I got to have new boobs without surgery. I loved how they jiggled back and forth as my stepbrother fucked me from behind. What surprised me was when my mother walked in on our tryst, the scene didn't faze her in the slightest! In fact, she encouraged me to be Brandon's little slut and even gave my nipples a tweak with her fingertips! Obviously, Brandon altered my mom and stepdad's minds to think that what we were doing was perfectly normal.

The following day, Brandon had me invite my best friend to our house to get the same treatment. Susan was the same age as me, of Asian lineage, and while many Asians dyed their hair brown or even blonde, Susan kept her hair jet-black and pretty much had the same style as mine, but with bangs. Before she came to our house that day, her tits were even smaller than mine, but in the middle of our three-way, Brandon magically made them grow to my size! After her initiation, my stepbrother was kind enough to let us nap and then we played together before he came back from a shower. The three of us started it all over again with the promise of more to come for a long time.

Brandon kept our three-way relationship, and his new power, on the down-low at school for a few weeks after our threesome, but then one day that all changed. Brandon allowed us to wear whatever we wanted to school, but we both always wanted to please him, and we knew what he liked. On that day, I chose a white, cotton tank top with a beige-colored pencil skirt. Susan wore a gray tank top with a white pleated skirt. I kept my sandy hair down, while Susan wore her inky-black hair in a ponytail but kept her bangs. Just for today, we were allowed to wear our bras and panties...for the time-being.

The three of us went to school together, but we split up once we got into the building. As the hours and classes trudged on, lunchtime approached, and Brandon wanted the three of us to be together. As I looked around, I found Brandon in a darkened corner hidden from view making out with one of my friends, Stephanie Wexler who was wearing her cheerleading uniform and had her blonde hair in a ponytail held up with a black scrunchie. Normally I wouldn't think to look in that area, but something twinged inside my head, telling me to look that way. Watching the two of them, I saw that he was fondling one of her clothed breasts and I couldn't help but press my thighs together in anticipation. As the two locked lips, I could feel my pussy start to moisten, and I couldn't help but suck in a breath of air through my teeth while spying on them, which alerted the two. He subsequently shooed her away with a slap on her ass. Obviously, he was flexing his new-found power, and he was in a very target-rich environment.

"Hey, sis, how's the day going so far?" He cheerfully asked with a smile on his face.

"Mmm, going well. It's kinda hard to concentrate because I keep imagining you stuffing my horny pussy with that big cock of yours," I said in a cheery voice, "how's yours?"

I couldn't fathom speaking like that to anyone before, but Brandon liked that kind of talk, and what he liked, I liked. So now, that's how I spoke.

Brandon smiled a shit-eating grin. "Pretty darn good, if I do say so myself. Stephanie is in my science class. I can't imagine why, but today, Mr. Bargle changed the seating arrangement so that we were sitting together," Brandon said sarcastically with a chuckle. He then made a "come hither" motion with his fingers and I went right in.

As the two of us were kissing, Brandon pawed my boobs and my nipples hardened underneath my top. We spotted Susan walking toward us, and she looked absolutely delectable in her pleated skirt and tank.

"Hi Brandon, Hi Terri! Think you could share some of that with me?" She pouted.

"Of course," We both said at the same time.

Indeed, the two of us both closed in on Susan. First, she shared her lips with me for a brief make-out, followed by Brandon. I softly rubbed her back and caressed one of her tits, and Brandon groped the other, while rubbing her bubble butt.

"Mmm!" I moaned, "If you two keep this up, we're going to need a quiet place to work off all this sexiness!"

"I thought you'd never ask," Brandon said with a naughty voice.

Susan protested, "What? Brandon, we can't have sex while we're in school! We'll get caught and probably expelled! Mmm," I had a hunch that Susan was probably feeling that tingling sensation in her mind just then which sometimes happens, at least at the start, when my stepbrother is doing his mind-altering thing. He then went in and started kissing Susan's neck while I went in to attack her lips once more.

"Susan," I said, "Do you really think anything's going to happen without Brandon's say-so?"

"Exactly. Don't worry, nothing's going to happen to us. Well, at least nothing that we won't enjoy. C'mon, let's go," Brandon softly urged.

He took us both by the hand and led us through the hallways to the swimming pool locker rooms. Both of us giggled with excitement, wondering what he had in store for us. Once we got to the lady's pool locker room, we saw it was deserted. He put his hands on our skirted asses and led us over to one of the benches.

"I know the swimming pool isn't being used at this hour, so we have just enough time for a quickie!" he said with a grin as he took a seat on the bench. "Now why don't you both show me just how much you missed me?"

Taking our cue, I stared back at him with a grin while Susan licked her luscious lips. At the same time, we lifted our tank tops to show Brandon our double d, bra-clad breasts while our man lifted both his hands to rest on our pantied cunts. He rubbed both our mounds while we took the time to unsnap our bras, revealing our neglected tits. We knew time was a factor, so Brandon took hold of both our panties and simultaneously pulled them down to the floor while we hiked up our skirts. Susan then grasped her boobs and fed them to my stepbrother's mouth. She leaned her head back and gave out a soft moan as our man greedily sucked on one nipple and then the other, swirling his tongue around the erect bud. Meanwhile, I fumbled with his belt, and once I freed his cock, I inhaled his fleshy staff like the horny, young slut that I became!

I slathered my tongue around his hardened cock, licking the underside where I knew everything felt so good. Up and down my head bobbed while Brandon reached around my ass and inserted a finger into my wet pussy. Susan then switched to kissing Brandon while he also fondled her cunt. It was pretty impressive how my stepbrother was able to multitask. As I watched him work us over, my skin tingled so much I thought it was positively vibrating. My pussy gushed even more, coating his fingers with my nectar, and I moaned on his cock.

"Oooh, so good!" I said, taking a momentary break and then dove back on his marvelous cock.

Once he felt that his cock was good and moist, Brandon stopped me from ravishing his steel and pulled away from Susan's lips. He had me stand up and put his hands on my hips, turning me so my back was to him.

"Susan, would you be so kind as to feed my cock into Terri's pussy please?" Brandon politely asked.

"Oooh, with pleasure!" Susan cooed. She got down on her knees, putting Brandon's cock and my quim right in front of her face. She took hold of his manhood with her dainty hand and lined it up with my womanhood. Her tongue came to bear, and she gave the underside of his cock one long lick and continued upward to give my sex the same long lick. Finally, she slowly inserted that perfect, fleshy specimen.

"Uhhhh, yeahhh!" I cried out in ecstasy.

With Brandon's hands on my hips, he started bouncing me up and down on his fully-erect cock. The three of us could hear the "pat," "pat," "pat," of our hips echo throughout the locker room. Though it wasn't quite easy, Susan extended her tongue and did her best to lather my clit as I went up and down. Sometimes her tongue got the cock pounding in and out of me. Sometimes she got my engorged clit. Neither of us complained. As she did this, Susan reached down underneath her skirt and started frigging her twat while pleasuring us both with her mouth and tongue.

"Uhn! Uhn! Uhn!" I cried out. At one point, one of Brandon's hands clamped down hard on my hip, solidly fastening my cunt to the root of his cock, while his other hand rose up and clasped one of my breasts. Instead of the up-and-down motion, he pushed back and forth causing me to undulate on his cock like a belly dancer. The less erratic movement allowed Susan to firmly plant her lips on my clit and she vigorously sucked on it. I leaned back, putting my head on his shoulder, and I craned my head searching for his lips as Brandon continued to wonderfully fuck me. Our tongues fought, and loved, and fought again. It was turning out to be a good day!

"JUST WHAT THE HELL IS GOING ON HERE!?"

The three of us froze...with Susan's mouth still on my clit, I might add.

Hearing that voice, it could only be Miss Ceppita, our hall monitor. Miss Ceppita's personality pretty-much had only two modes; kindly, elderly, woman in her late fifties, and grizzled troll. Guess which one she was right now.

Susan blinked as she took her mouth away from my clit and stood up, facing Miss Ceppita looking down at the floor. Brandon used his hands to slowly extricate me from his dick, feeling the sensation in the nerve endings of my cunt centimeter by centimeter and I must admit.

"Mm!" a slight moan squeaked out of my lips despite my attempt at self-control. Miss Ceppita curled her lips and grunted in disgust. I stood next to Susan, looking at Brandon who didn't seem to worry in the slightest.

"All of you, get dressed right now!" the angry hall monitor barked at us.

I picked up my panties from the floor and looked at my stepbrother. He seemed like he didn't have a care in the world. Like us, he did what he was told, which surprised me.

"Umm, are you gonna like, do something about this?" I nervously asked him, hoping he would use his mind powers to get us out of this situation. Susan was too mortified to say or do anything except continue to get dressed. Neither of us bothered to put on our bras and we just left them on the floor.

"Not to worry," Brandon reassured, "It's all part of the plan."

Miss Ceppita grimaced, "What are you talking about? What plan? Just, come with me," she ordered once we finished putting on our clothes.

She led us through the hallways walking at a brisk pace. My stepbrother followed her with the two of us behind him. I exchanged looks with my best friend and we both felt our lives would be over soon. I wondered what would happen to us. Was Brandon not going to use his power? What would happen to our reputations? We'd all be the laughingstock of the school, not that we'd be going there anymore. Shit, we might even make the news!

My nerves were shaking the closer we got to the main office. I trusted Brandon to get us out of this, but I just couldn't stop shaking. Then Susan came up with an idea to try and talk us out of this situation.

"W-wait a second, please, Miss Ceppita. Think about this," Susan said. The old hall monitor stopped, and all four of us did the same, "If...if we get sent to the principal's office, this might get out to the public and even the news. It, um, it might cast the school staff in a negative light for letting this happen," Susan negotiated. She was scared like I was, but I had to hand it to her to muster up the courage to try something. I didn't say anything because I still trusted my stepbrother to do something, and I had known him longer than Susan. Brandon, of course, was the only one among us who was as calm as the Dalai Lama.

"Honey, I couldn't care less if the entire world heard about this! If they think we're bad staff, then we're bad staff. You know damn well you shouldn't be doing what you were doing in the locker room. You broke the rules," she pointed her finger at Susan, "not us, and now you'll have to face the consequences!" As angry as Miss Ceppita was, she didn't curse, and she didn't say out that we had a threesome in the lockeroom. Maybe she wanted to save us from humiliation in case others could overhear us before we faced the music.

"It's going to be okay," Brandon said looking behind his shoulder. I could feel a little tingling sensation in my mind and I did start to calm down. I took a deep breath, and I wordlessly thanked my stepbrother for staving off the panic which he probably also did for Susan.

"Quiet!" Miss Ceppita commanded.

Finally, we made it to the main office and then we stood just outside the door to our principal's office which belonged to Dr. Jaimie Gleason.

"Wait here," the angry hall monitor told us.

She knocked on the thick, wooden, door and placed her ear to it so she could hear whether or not our principal ordered her to come in. She did, and she went inside while the three of us waited.

Once the door opened again, we heard Dr. Gleason yell at us.

"Get in here, all of you!" she bellowed.

Miss Ceppita exited the principal's office, not even looking at us, but as she left the main office, she froze in her tracks for a few seconds, and then continued to leave.

We quickly walked in. I closed the door and Brandon and Susan sat in the two chairs in front of Dr. Gleason's large desk while I stood next to my stepbrother.

Dr. Gleason was probably the most unhappy, beautiful, 39-year-old woman in the world. She stood in front of her desk, leaning her shapely derriere upon the edge with her arms folded across her chest. She was tall, nearly six feet, with a mound of blonde hair wrapped in a tight bun behind her head. She wore a pair of silver, oval-lensed glasses perched on her thin nose through which she stared down at us. Her breasts were even larger than mine and Susan's, definitely an e-cup, and probably not even an ounce of sag when seen without a bra. She had long, shapely legs that seemed to run on forever and they were clad in beige stockings (or pantyhose, I wasn't sure at that point). A dark-brown pencil skirt that went to her knees wrapped around her shapely buttocks. She had a cream-colored blouse that buttoned up all the way to her neck. A matching dark-brown blazer with the same-colored pumps completed her outfit.

Brandon still had that knowing grin on his face. I looked at him, and then I looked at our principal, and I figured out his plan. I couldn't help but smile as the realization came over me.

"So, I understand that the three of you had sex in the women's swimming locker room a little while ago, is that right?" Her calm tone of voice dared us to deny it. Susan and I stayed quiet, and we just let Brandon speak for us.

"Yeah, pretty much," he answered. Dr. Gleason wore a surprised look on her face when Brandon nonchalantly admitted to the accusation. She sighed and put her fingers to her temple after hearing this. After a few seconds, she spoke to us again.

"Do you think this place is your own personal brothel? It isn't. Just what do you think you were doing in there? If this gets out, you three will be in a lot of trouble!" she threatened, but it seemed to me that there was slightly less venom in her voice.

Susan saw it too, and she finally relaxed and even smiled.

Brandon shrugged his shoulders. "Well, it was lunchtime, none of us were hungry, and we had some time to kill. I knew that the pool wasn't being used, so I had us go over there for a quickie. As for what we were doing there, I could tell you, but wouldn't it be better if we showed you?" Brandon said with an excited smile.

"What? Show me? What are you talking about? I don't want you to show me! What-" at that moment, Dr. Gleason put her fingers to her temple and let out a relaxed sigh. "What, what happened?" She said as she unbuttoned the top button of her blouse. I didn't know if she was asking what happened in the locker room, or if she was asking what the tingling sensation was in her mind.

"Susan, why don't you take my cock out of my pants and wrap your lips around it? Terri, lift up that shirt and feed me your tits. In fact, both of you lift up your tops. I'm sure it's dawning on Dr. Gleason that she would love to see both of your tits right about now," Brandon calmly ordered.

"What!? I, well, yes, their tits are very nice. I mean boobs! I mean, damnit!" Dr. Gleason was probably trying to say something less vulgar, but I knew it was a losing battle. I lifted my tank top over my head and dropped it on the floor while Susan did the same. The two of us then lifted our skirts and slid our panties off as we would no longer need them.

I gave a mischievous look towards the principal, cupping my breasts and bringing one up to my lips. I gave my nipple a lick before subserviently feeding the hardened bud to my stepbrother.

"Sssss, hmmm!" I hissed and groaned once I felt my stepbrother's lips on my nipples once more.

Dr. Gleason just stared dumbfounded at the three of us and licked her lips just a little.
