Keith

I hadn't met up with my friends since the night I'd cum down my brother's throat. Part of me was terrified that they somehow knew, that I would be exposed as a freak. I mean, it was pretty twisted, right? My brother dressed up as a cute girl and I found it sexy as fuck, so much that I wanted to stick my cock in him. I thought about the huge load I'd busted yesterday, jacking off to the memory of Zoey -- Zach -- blowing me and swallowing my jizz. I almost clogged the shower drain with my ejaculate.

Speaking of which, I hadn't taken my supplements today. I went through my bottles, throwing back pills one after another. Zinc, fenugreek, maca. I snacked on walnuts and dark chocolate, and my diet included a lot of beef, spinach, and garlic, some oysters whenever I could. I exercised often, made sure I got enough sleep, and tried to keep my drinking moderate. People thought I was a bit of a health nut, when the truth was... I just wanted to cum like a fire hose. I chuckled to myself. If they only knew how big a dork I was.

I was just having a night in, having turned down an invite from the boys because, as mentioned earlier, I couldn't be drinking every night. Besides, my internship was starting soon, and I wanted to get into the proper lifestyle sooner rather than later. Yet as I lay in bed, just messing around on my phone, my thoughts drifted back to my little brother. After what happened, he'd been awkward both yesterday and today. Which was understandable. Relatable, even. How were we supposed to act around each other now? Did we just ignore it? I definitely couldn't let my friends find out I'd done some gay shit like that. Was it weird I was more hung up on the gay part than the incest part? He was my brother, after all. Then again, there were quite a few places in the world that felt the same, some of them only a couple states over.

There was a soft knock at my door, and I frowned. Mom and dad went to bed hours ago, which meant... Taking a deep breath, I stood to open my door. Standing outside in the dark hallway, wearing a tiny black dress, a sexy pink wig, and nude makeup, was Zoey. Zach, I corrected myself. How did I keep forgetting that. He was my fucking brother, and his name was

Zach.

"I need your help," Zoey whispered.

Quickly, I grabbed her arm and yanked her into my room before closing the door and locking it. "Are you crazy? What if mom or dad saw you?!" I hissed.

"They're asleep. I checked." She shifted from one foot to another nervously, nibbling her lip a bit.

"You..." I didn't even know what to say to her. The little black dress was incredible on her. If she wanted something more flattering of her less-endowed figure, she would have chosen a halter top. Yet almost as if drawing attention to her flat chest and pert nipples, her spaghetti strap choice hugged her body like it was painted on, revealing that her hips were in fact slightly hourglass. Seeing her like this was bringing back vivid memories of her gagging on me and gulping down my seed, making me swell with lust. It was impossible to disguise as the pant leg of my shorts lifted clear away from my thigh, and she gasped. "What is it?" I managed, trying to draw attention from my erection.

Her gaze lingered on my tenting manhood a moment before shyly meeting mine. Holding out a hand, she presented a small silver key. "This is yours."

"I'm sorry, what is it for?" I asked, taking it. I didn't remember ever owning something that this key was used on. I found out why when she lifted the hem of her dress. Between her legs was a pink plastic chastity cage, the key for which was now in my hand. The cage was minuscule, and Zoey's hips twitched backward every so often under my scrutiny. And her deep blush... "Mine, you say?" I growled.

She nodded, looking desperate for me to unlock her. I grunted and pocketed the key, and her forlorn expression tented my pants a bit more. She didn't protest though, simply squirming more and averting her gaze.

"You said you needed help?"

She looked at her feet in shame, the blush spreading down her tender neck while she turned around and lifted the hem around the back of the dress. Looking back at me was her plush ass, looking juicy and squeezable and begging to be eaten out. Unable to help myself, I reached down and cupped both cheeks, earning another gasp from her. Spreading her apart, I caught sight of the curved black T-grip of a sex toy, either a plug or a string of beads.

"I can't take it out myself," she whimpered, her voice high and girly. I adjusted my shorts and grunted again, pushing her by the ass toward my bed. Forcing her down to her knees and bending her over the mattress, I studied the grip for a moment before pinching it and attempting to extract it.

"Who did this to you?" I questioned. For a brief nasty moment, I wondered if it was Cody. Cody had dominated her and made her his, and my blood boiled. I knew I'd have to murder Cody one day, and it seemed today was that day. But if that were the case, Zoey wouldn't have the key to her own cage.

"Ellie," she replied, her voice still hushed. That made much more sense. What still didn't make sense was why she hadn't unlocked the cage herself. Unless... she was submitting to me. I throbbed even harder, if that was possible, and I cleared my throat.

"I think she used the wrong lube for something like this. The toy is dried out." I went to retrieve a towel and a bottle of lube, spreading out on the floor next to my bed. "I'm guessing she used a water-based lube, which is good for short sessions and cleanup. But if you're going for hours, you need silicone-based, because right here your body absorbed the lube and left nothing behind for when you pull the toy out.

"It's a good thing you didn't try to yank it out yourself," I continued. "You could rip your insides if you don't do this carefully, and that could lead to some serious issues. Is this a plug or beads?"

"Beads," she whispered. "Studded."

"That probably could've shredded you if you took it out dry," I grunted. I applied lube to a fingertip and rubbed it around her asshole and the stem of the toy. Then, very slowly, I started working the toy in and out, perhaps by only a millimeter. Thus began the slow process of gradually applying lube to a toy that was stuck inside my sister -- brother.

She was groaning apprehensively as I worked out the first and largest bead. By now, her sphincter was properly lubed, but the toy was still dry and needed lubrication at every turn. My breathing was deep and heavy as I watched the large studded bead make her ass pucker while I coaxed it to relinquish the toy. It finally surrendered the bead with a squelch, and Zoey moaned erotically.

"Hardest part is over," I told her. Speaking of hard, my cock had found its way out of my shorts and was pushing my pant leg up to my crotch so that it could stand proud at the sight of this erotic display. "You okay?"

All she could manage was some unintelligible sound of arousal and a single nod, letting her head drop onto my mattress while I raised her hips. I kept working at it, easing the toy out carefully, until the sixth bead finally slipped out of her glistening hole. I sighed in relief, placing the beads on the towel as her sphincter puckered after the arduous undertaking. Staring at her anus as it winked at me, I licked my lips and raised my hand. I couldn't help myself.

"Keith!" she whimpered as I pushed a slippery finger into her ass, twisting it this way and that as I delved into her most forbidden places.

"Tell me to stop," I ordered, but she just kept mewling with restrained pleasure. I twisted and pressed my finger into her prostate, and she moaned while her chastity cage shifted. What the hell was I doing? I was about to pleasure my brother, that's what. I pushed against the prostate a few more times, and she gripped the sheets and arched her back, teeth grit as she moaned. "Are you going to be my girl?" I murmured.

"I'm... not a girl..." she panted.

"We'll see about that." I went back to my sex drawer and retrieved what I needed, laying out the set of buttplugs out on the towel. The first one was thin, but just as long as the rest, and I held it out in front of her for her to see. "This is going inside of you. Tell me to stop."

She stared at the toy for a few seconds, then gulped and lowered her forehead onto the mattress. I lubed the toy up and began spreading her open with it, and after the beads, she already seemed nice and prepped for more practice. I had no idea what Ellie had been thinking, but I could only conclude that she was presenting her best friend to me. The detail that it was my brother seemed to be getting less and less significant the hornier I got.

We worked our way through my set of four plugs, each one thicker than the last. Zoey was being a good girl, taking everything I gave her without complaint. Every now and then I had to stop and let her adjust when it seemed like she was in pain. She never said anything, so it was up to me to know when to stop. It felt like a special kind of submission, steeped in trust, and I admit that I loved every second of it.

Finally, she was ready.

Ready for what?

I wondered to myself. It was a waste of time to lie to myself, pretend I didn't know the answer, but my dignity made me go through the motions anyway. I applied more lube to her ass, and she looked back at me and watched as I undressed and rolled a condom onto my strained cock. Her eyes were heavy with lust, her lips parted erotically, as if she too was waiting for this moment.

I knelt behind her, my sex pointed at her slippery hole as I applied a coat of lube onto myself. "You have to tell me to stop right now," I rumbled, threatening to burst out of the condom at any second. Her only response was to back into me, pressing my tip against her entrance. I took a firm hold of her hips and slowly pulled her onto me, and I could hear her straining against her cage as I filled her insides with cock.

She was shivering in delight, making undignified slutty noises when our hips finally touched. Eight-and-a-half inches of meat in her ass, and all she could do was moan as I took her virginity. I started off slow, savoring the tightness of her body as I ran my full length through her clenching ring over and over again. She held onto my crown with a death grip, which suited me just fine.

An invasive thought snuck up on me. I'd wanted to fuck his ass ever since the bar. Was I gay? No. No, fuck that. I'd had plenty of anal with tons of girls before. It was why I knew so much about it, why I could take care of him -- her -- him so well during his first time. Her. God damn it, my brain couldn't handle all this.

I slammed into her and she cried out. Clamping a hand over her mouth, I began savagely pounding into her. She could do nothing but hold onto the bed for dear life. She was screaming now, tears streaming out of her eyes, but she was still slamming her ass back onto me. Suddenly she began spasming, her hips bucking erratically. I looked down to see that she had shot a pathetic spurt of cum out the hole of her chastity cage, and I stopped thrusting to give her a moment to recover.

"You okay, baby?" I panted, moving my hand so she could speak.

She looked dazed, eyes unfocused and head lolling around as she lay collapsed on the bed. Finally, she breathed, "Keep fucking me."

She was petite enough for me to pick up and move us onto the bed proper, still impaling her on my shaft. I slipped the straps of her dress off her shoulders, pulling down the neckline until I had access to her pearly pink nipples. Pinching one in a massage, I started pumping up into her again as I held her against me in sinner position. She groaned, her eyes crossing as she took my entire length once more.

I'd tasted dozens of girls in school, spanning the full range of true-blue virgins to certified sluts. I'd corrupted pure-hearted bookworms and become the exclusive master of sex-crazed fiends. Yet they all paled in comparison to Zoey. She made me feel like I was about to cum like I'd never cum before. I sucked on a spot on her neck right under her ear, intent on marking her as mine. She cooed sensually, and I was done.

Torrents of cum filled the condom inside her, making it balloon out of control as I gave her my last few thrusts. Spasms racked her body again, but this time nothing leaked out of her cage as she came on my cock for the second time. She was clenching me so hard, it felt like she would squeeze my manhood off, and it just made me cum more.

As we lay there recovering, I was struck with panic. I'd just fucked a guy. The blowjob had been borderline, but this was undeniably gay. As I moved to shove him off of me, Zach leaned his head back to look at me.

"Keith... I love you..." whispered Zoey.

The L Bomb, huh? I didn't know what to do. My emotions were still in utter turmoil. Out of all the girls who'd said it to me, I'd never said it back. And I was supposed to reply in kind at a moment like this? I couldn't do it.

What I did do was lean down and kiss her, and she let out a sigh of content before drifting off to sleep on my chest. I was still lodged inside her, and I reasoned... that cleanup could wait until morning, along with all my turbulent thoughts.
