All families have secrets. Some are small. Some are big. Some are so extreme minds are blown and relationships forever altered at the mere mention of them. That is the kind of secret my family had been keeping from me for the past eighteen years.

It was my birthday. My eighteenth birthday. As all young women my age, I was excited at the prospect of becoming an adult. But it had nothing to do with being allowed to drink, smoke and do all those other horrible things people do just because they can. My enthusiasm came from a completely different place. According to the rules of the family, I would finally be told the family secret. At least that was what I had been told over and over again.

“You’ll understand when you’re eighteen,” would say my relatives whenever I questioned them about the family secret.

“I can’t tell you,” said others. “Not yet.”

“It will all make sense once you’re an adult.”

Is it really surprising that I spent my entire youth longing for the day I would finally leave my childhood behind? But now the long-awaited moment had finally arrived.

I awoke with a smile. At first I thought it was because I was now an adult. Then I remembered the secret and my birthday suddenly seemed unimportant. I was tempted to leap out of bed and rush downstairs, but that probably would have been a mistake. It’s not like my parents never saw me naked, but I seriously doubted they would be thrilled if I paraded around in my birthday suit. Then again, it was my birthday. Would it really be so bad? Then I remembered my brother and my blatant callousness immediately dissipated. I had no proof of it, but I had suspected for a while that Ryan had a crush on me. I knew he would never actually do anything about his perverse infatuation, but I didn’t want to risk giving him any ideas. So I opted against nudity being my first act as an adult.

I slipped out of bed and shivered as the cool morning air tickled my skin. I glanced at the mirror, as I did on all my birthdays. I looked exactly as I had the day before, but there was something different about my reflection today. Was it the way my dark locks glistened in the sunlight? No. Perhaps it was the perkiness of my breasts or the stiffness of my nipples. No. My eyes dropped to my tight, clean-shaven slit. Was it because, though I had lost my virginity many years ago, I still looked as innocent as I always had? No. My final thought was that it had something to do with the bounciness of my butt. When that proved untrue, I was left speechless. It wasn’t until I took my reflection in as a whole that it finally hit me.

My posture had changed. My head was held high. My shoulders were pulled back. My back was erect. I held myself up with poise and pride. I had never felt this good. Nor had I seemed this put-together. Even without my clothes, I looked like I was ready to take on the world. And I was. At least I would be as soon as I learned the family secret.

I was tempted to slip into my nightie, but I feared that would be unwise. Ryan would probably already be downstairs, enjoying breakfast in company of our parents. The last thing I wanted was to upset him and risk ruining what may very well be my one and only chance to learn the secret. What if I only had this one opportunity? What would happen if I messed it up? What if…

I could have kept going all day, but I eventually shook the uncertainty from my frame and focused on picking out an outfit. Within minutes, I was slipping into a pair of skin-tight jeans and a plain white t-shirt. I was in such a hurry that I failed to put on a bra. Hopefully Ryan wouldn’t notice.

I was tempted to rush downstairs, but I made a quick pit stop at the bathroom. I relieved my bladder, brushed my teeth and applied a thin layer of makeup. It’s not because I was now an adult that I no longer cared about my appearance. Once my morning routine was complete, I gathered myself and made my way downstairs.

As I had expected, Ryan was halfway through his breakfast. Only my parents were nowhere to be seen.

“Where’re are Mom and Dad?” I asked as I strolled into the dining room.

Ryan looked up from his bowl of cereal and smiled.

“They had to leave early for work,” he answered. “I guess it’s just you and me today.”

I sighed. It’s not like I didn’t enjoy spending time with Ryan, it’s just that I was looking forward to being clued in as to the family’s mysterious secret. I could have asked Ryan, but I feared he would make fun of me. He always did it kiddingly, but I was in no mood to be teased. I guess I would just have to wait for our parents to return.

Part of me felt resentful that our parents weren’t there to wish me a happy birthday, but I knew that wasn’t fair. Mom and Dad worked hard to keep Ryan and me fed—they insisted we focus on our studies rather than get part-time jobs to help pay for college—but I missed having them around. At least Ryan was here.

“Want some cereal?” asked my brother.

I nodded and took a seat across from him. There was a bowl waiting for me.

“Happy birthday,” said Ryan as he poured the cereal into my bowl.

“Thanks,” I replied as I grabbed the carton of milk and drowned the contents of the bowl.

There was a moment of silence as we ate. Ryan and I didn’t have much in common. He was very active. He went to the gym twice a day and competed in dozens of sporting events each and every month. He lived for physical exercise. I preferred to curl up on the couch and read a good book. I still exercised each day, but my workout routine was far less exhaustive than Ryan’s.

“I’m going to work out,” he said, moments after swallowing the final mouthful. “Want to join me?”

I hesitated. Ryan and I never worked out together, but my party was not for another nine and a half hours and a good workout sounded like a great way to pass the time.

“All right,” I agreed as I gulped down the last few mouthfuls.

“Meet you downstairs in five,” said Ryan as he retrieved my bowl and, along with his, carried it into the kitchen.

“O-Okay,” I mumbled, slightly surprised by his eagerness.

I made my way upstairs and changed into my workout clothes—a sports bra, a pair of skin-tight shorts and running shoes so light it felt like I was barefoot. I also tied my hair in a ponytail and removed my makeup. I then made my way down to the basement.

As I mentioned before, Ryan was a sports fanatic. But he wasn’t the only one. My father was also an avid believer in daily exercise. As such, we had our private gym in our basement. There were free weights to spare. Five treadmills—one for each family member. Multiple cardio machines, including elliptical and arc trainers and many more I knew very little about. There were even a few punching bags, as well as over a dozen exercise balls and exercise mats. It was a dream come true for any fitness lover.

Ryan was already warming up on the treadmill.

“What’s the plan?” I asked as I hopped onto the neighboring machine.

“Get ready for the most intense workout of your entire life,” answered Ryan.

I groaned, but said nothing. I had been wanting to increase the intensity of my workouts for some time, but I feared Ryan’s definition of “intense” was slightly different than mine. I believed in working up a good sweat. He preferred pushing himself to the very limit.

“All right,” said Ryan after a ten-minute jog. “Let’s get started.”

He hopped off the treadmill and made his way over to the free weights. I groaned, but followed him. I expected Ryan to work out alongside me, but apparently he was there only for moral support. I guess that ten-minute jog had been his idea of a hearty morning walk.

At first I was grateful for my brother’s help. I rarely worked out with weights and his tips and tricks helped me a lot. But it wasn’t all fun and games. Ryan pushed me harder than I had ever been pushed. I nearly reached my breaking point more than once, but my brother knew when to push me and when to let me rest. Nonetheless, it was the most intense workout of my entire life. Once we were done working on the arms and shoulders, we moved on to the chest. Then came the leg workouts. By the time we started working on my abdominal muscles, I was ready to give up. But Ryan refused to let me quit. He pushed and pushed until finally he told me it was over.

I crumbled into a heap of sweaty, trembling limbs. But I only had a few minutes to catch my breath before Ryan announced it was now time for the cardio workout. I had been so focused on surviving the strength exercises that I had forgotten all about cardio. I was tempted to give up, but Ryan would not allow it. He yelled and insulted me until I climbed onto the treadmill.

I was hoping for a slow jog. What I got instead was a kick in the butt and the longest, most excruciatingly exhausting run of my entire life. I lost my footing more than once, but Ryan was always there to catch me. Unfortunately, he was also there to insult me each and every time I faltered. By the time he finally allowed me to dismount the treadmill, I was so exhausted that I only made it two steps before my knees gave out. This time Ryan wasn’t there to catch me. I crumbled to the ground. And that was where I remained for the next few minutes.

No one spoke for the longest time. Ryan’s silence was due to the fact that he had nothing to say. I didn’t speak because I was physically unable to. That’s how exhausted I was.

“Do you want to know the family secret?” Ryan’s voice suddenly exploded in my ears. My heart leapt in my chest as my eyes few open. I struggled to get up, but my tired body wouldn’t allow it. All I could manage was a weak “Yes” and a slight nod.

Ryan’s lips curled into a smile. “I’ll be right back,” he promised. He vanished from sight moments later and did not return for a few minutes. When he finally reappeared, he was accompanied by the family dog.

Rex was a boxer. He wasn’t big, but he fully made up for it with sheer power. He was the dog equivalent of Ryan. Shredded. But, just like Ryan, he also had a soft side. And, unlike my brother, he was happy to show it more than once or twice a day. Actually, he was pretty much the happiest dog I had ever seen.

“What…” I began, but the rest of the words died in my throat. I was too exhausted to speak more than one word at a time. I barely even managed to lift my head to see what Rex was up to. He stood between my legs, sniffing my crotch. I wanted to shoo him away, but I was too weak.

Ryan smiled down at me.

“I know this must be confusing,” he said, “but it will all make sense soon enough.”

I said nothing.

“I know you’ve been wondering about the family secret. Believe me when I say you’re not the only one.” He paused to give me a reassuring smile. “So here it is. The family secret can be summed up in one word. Bestiality.”

I didn’t react. And this time it wasn’t because I couldn’t move. I just lay there, staring at Ryan in disbelief. Had I heard right? Had he said the family secret was bestiality? What the hell did that even mean? Unless…

I suddenly remembered the dog between my legs. He was still avidly sniffing my pussy.

Ryan’s lips curled into yet another smile. “That’s right,” he said. “You’re about to have sex with Rex.”

I couldn’t believe it. Actually, I could. What I couldn’t believe was that this was the secret I had been fantasizing about for years. I had expected something fantastic, like a secret fortune, or the revelation that we were in fact royalty. I had also imagined our family being part of some secret society. But never had I pictured anything as simple, yet perverse as bestiality.

“I don’t understand,” I somehow managed to say. It came out as a soft whisper, but Ryan hear every word.

“I know it can be confusing at first, but it’s really quite simple.” He crouched down next to me. “The secret is actually a tradition. Put simply, every member of our family is expected to have sex with an animal on the day of their eighteenth birthday. If they don’t, well, they get expulsed from the family. So, unless you want to be cast out, I suggest you get used to the idea of having sex with Rexy here.” He patted the canine’s head. Red barked joyfully. I couldn’t help wondering if he knew what was about to happen.

Ryan gave me a few seconds to process this new information. But no amount of time would allow me to come to grips with the fact that my brother—no, my entire family—expected me to have sex with an animal.

“What will it be?” asked Ryan after a minute of silence. “Bestiality or expulsion?”

I knew what I had to do, but there was something I had to say first.

“If you’re lying to me,” I groaned, “I’ll kill you.” I had threatened by brother before, but this was the first time I really meant it.

Ryan chuckled. “Fair enough. Now are you ready to get started?”

I wasn’t, but I nodded anyway.

“Let me give you a hand,” he said as he lifted my head and placed something soft underneath it. I think it was a rolled up exercise mat. I suddenly realized why my brother had worked me so hard. He knew I would be reticent to agree his perverse offer, so he had made it easy on himself by wearing me out so I would be unable to fight back. But still he had allowed me to choose. I had to respect him for that.

Ryan whistled. “Fuck,” he ordered as he pointed to my lips. At first I didn’t understand what that meant. But then Rex strode toward me and I noticed his erect member for the very first time. I had caught glimpses of it before but this was the first time I saw it in all its entirety. It was long, red and pointy. Not to mention incredibly massive. At least for a dog his size. His spear was roughly the same size as the average human’s.

I watched, powerless as the studly animal came to stand over my face. His cock now hovered over me, the tip less than an inch from my lips. All he had to do was jerk forward and the shaft would be forced into my mouth. But he didn’t make a move.

“Open up,” my brother whispered into my ear.

I hesitated for a moment. Could I really go through with this? But then I thought about what my life would be like if I was expulsed from the family. No roof over my head. No food on my plate. No money to pay for my studies. No prospects whatsoever.

I didn’t have a choice. I had to do this. I took a deep breath, closed my eyes and opened my mouth. Moments later the tip of Rex’s cock slipped past my lips.

Sucking a dog’s member was not that different from sucking a man’s. Sure, the spear was slightly harder. Not to mention way hotter. But aside from that, it was essentially the same. I probably could have tricked myself into believing the shaft that now glided in and out of my mouth belonged to a human, but for some unknown reason, I didn’t want to. I wanted to fully experience my first bestial encounter. And that was exactly what I did.

I was still weak from my recent workout, but I had regained enough strength to wrap my lips tightly around my lover’s shaft. I also managed to move my tongue about, stroking the member with increasing zeal. Before long, soft moans began toppling from my lips. I was surprised, but not ungrateful. Bestiality was kind of gross, yet all I felt for Rex was an overwhelming sense of gratitude. He was the only one capable of keeping my life from crashing down around me. And if that meant sucking his dick, then so be it.

I blocked out the rest of the world, focusing only on my lover’s cock. I sucked it like I had never sucked before. It wasn’t hard since Rex was doing most of the work. He propelled his shaft in and out of my mouth with every increasing intensity. All I had to do was keep my lips wrapped tight and hang on for the ride.

And what a ride it was. I’m not sure how long it took, but the canine’s cock eventually started twerking. Before long it was convulsing madly. Moments later, hot semen poured into my mouth. I was so focused on the blowjob that I didn’t immediately understand what was happening. It wasn’t until the hot, and surprisingly tasty, cum glided down my throat that I realized my lover was climaxing.

Human cum is kind of gross. I had expected dog semen to be just as repulsive, but I was pleasantly surprised. Not only was it incredibly hot, but it was kind of sweet. Not in an overpowering way, but just enough to make me crave more. Luckily, that was exactly what I got. Squirt after squirt of it poured into my mouth. And it continued flowing until enough had found its way into my stomach that a great warmth had spread through me. I now felt a sense of excitement bubble through my entire body. Then again, that may have been arousal. All I know is that I was actually disappointed when the final squirt oozed out of my lover’s shaft. But that didn’t mean the blowjob was over. Rex kept thrusting his member into my mouth until the blood came rushing back to it. Before long, he had another raging hard-on. Only then did he finally pull away.

I lay there for a while, panting heavily. The blowjob hat tired me out more than I had initially realized. Or maybe I was still recovering from my intense workout. Either way, I remained unable to move for another few minutes. It was not until Ryan spoke that I remembered he had watched me suck the family dog’s member. I blushed, but I was still so flushed from my recent physical exertion that it probably didn’t even show.

“Nice work,” said my brother. “Do you think you’re ready for the next part?”

“Next part?” I asked, speaking in a normal voice for the first time in what felt like forever.

Ryan chuckled. “Did you really think a blowjob was all it would take?”

I hadn’t really thought of it, but I now realized he was right. As fun as the interspecies cock sucking had been, it wasn’t technically sex. Which meant that I still had not guaranteed my place in the family. I expected to feel despair wash over me, but all I felt was excitement. As impossible as it seemed, I was actually looking forward to having sex with Rex.

I was still very weak, but I managed to sit up. And with my brother’s help, I was able to remove my clothes. They were drenched in sweat and clung to my frame, but Ryan was strong. In fact, he nearly ripped them to shreds. And for good reason.

Ryan had a crush on me. That much was clear when he began studying my exposed frame from every angle. I feared I had made a mistake in allowing him to see me naked, but it was too late to back down now. All I could do was hope the bulge in his pants remained just that.

It did. Still, I was reticent to take my eyes off him. But when he showed no indication of wanting to explore my frame with something other than his gaze, I turned my attention to Rex.

The studly canine stood nearby, staring at me expectantly. The sight of his erect member told me he was ready and willing to penetrate me. But he didn’t make his move until I made my own. I scrambled to my hands and knees, groaning from the effort. I wobbled dangerously, but Rex came rushing to my aid before I could tip over.

It was my first time being mounted by a dog. His front legs slid along my frame until they had my waist pinned between them. Using my body to keep upright, Rex hopped forward. Moments later the tip of his member was pressed to my labia. He hesitated for a moment, as it waiting for my permission.

“Do it,” I said.

That was all it took. One second I was trying to imagine what it would be like to have an animal’s shaft invade my slit. The next I no longer had to imagine. A soft moan fell from my lips as my lover’s cock slid deeper and deeper into me. In less than a second, every last inch of it has been swallowed up.

I couldn’t believe how good it felt. The shaft itself was slightly narrower than my previous lover’s, yet the knot that stood at its base was the biggest thing to ever invade my pussy. Yet there was not a single drop of pain. Only arousal. And quite a lot of pre-cum.

“Fuck me!” I begged. I hadn’t planned on saying it, but I didn’t regret the words. Nor did I regret what happened next.

“Oh god!” I moaned as Rex began thrusting. His cock darted in and out of me with such speed that it was impossible to tell when it was in and when it was out. It felt like once continuous penetration. And I loved every second of it.

I wasn’t prepared for how incredible my first real bestial experience would be. But in just a few seconds of pounding, Rex had put all my past lovers to shame. Perhaps it was the animalistic intensity of the lovemaking. Or the fact that bestiality was illegal. I know only that I never felt so happy in my entire life.

And my joy only increased with time. As did the intensity of my moans. I barely even noticed my brother stroking his shaft through the thin layer of his shorts. I no longer cared that he had a crush on me. I was enjoying the best sex of my entire life and nothing else mattered. Well, aside from the intense orgasm I only now realized was growing within me. It grew and grew until it seemed to fill my entire body. Only when it could no longer expand did it finally explode.

“FUCK!” I yelled at the top of my lungs. Squirt after squirt began pouring out of me moments after the cry had escaped. The first few belonged to me, but as time passed, Rex’s semen joined mine. We were now coming in perfect synchronicity. And I was loving every second of it.

Moans toppled from my lips. Orgasmilk filled the air. It clung to my legs. And my stomach. It flew high into the air and rained down upon me. My lover was just as cum-stained as me. Some of the hot nectar even made it all the way to Ryan. But I didn’t care what happened to my brother. Only my lover and I mattered.

It seemed to last forever. Yet at the same time it felt like it was over in mere seconds. All I know for sure is that what little strength had returned to my frame was drained away the moment the final squirt oozed out of me. I don’t recall hitting the ground, but the world went dark moments after Rex’s shaft slipped out of me for the very last time.

I must have been out for quite a while, because most of my strength had returned by the time my eyes fluttered open. I was still sore from my recent workout—both physical and sexual—but I could now move about freely. I could also speak without fear of passing out from exhaustion.

“Is it over?” I asked.

Ryan chuckled. “For now,” he said.

“What does that mean?” I asked, my heart racing. “I did everything you asked. Everything!”

Ryan nodded. “You did,” he conceded, “but this was only the beginning. You have a long way to go before you become a true member of this family.”

My heart sunk. But at the same time I felt a twinkle of excitement at the thought of another bestial encounter.

“Don’t worry,” said my brother. “You’ll enjoy what comes next. I promise.”

To be continued…
