Kelly and I walked back to the house, pits in our stomachs, both on the verge of throwing up. What was waiting for us in that house? Who was watching us from Kelly's room window? Was it really someone watching? Or was it just the A/C unit blowing the curtain? I'd never seen our A/C do that to my curtains before, but maybe there was a vent right under Kelly's window that I never saw before? And even if it was just the A/C, how quickly would the Michaelsons send a text to mom and dad letting them know what was on their security camera? I wanted to trick myself into thinking the camera quality was poor enough that I could lie to my parents and say that it was me and Jessica, but it was the same system I had helped dad install this past summer...and I had seen the video quality of those cameras before. They would be able to make out, very clearly, the two faces of the siblings who live next door - fucking each other in their jacuzzi.

I looked at Kelly as we snuck back into the house. She was shaking and crying. I grabbed her hand.

"It's going to be ok Kelly" I lied. "I promise. Everything will be fine."

We quietly walked back up the stairs and I followed Kelly into her room. I had to see if there was a vent or something that could have moved that curtain. I had to know, before I got back into bed with Jessica, if she had been watching us. The pit in my stomach sunk even further down when, of course, no vent was anywhere near the window. The heater was on and the vents in her room were blowing hot air out of them, and the curtains were standing perfectly still. Someone had seen us.

I grabbed Kelly, and brought her in for a hug. I stroked the back of her head and kissed her on the cheek.

"Everything is going to be ok sis."

I pulled back and gave her a loving kiss on her lips, not knowing if that would be the last time we could do that. Our little incestuous affair was potentially about to blow up this family, and I wanted one last moment of peace and love with Kelly. She kissed me back, hard and firm, not wanting to part. She knew what I knew - that when this kiss was over, we would have to face reality.

I snuck out of her room and back into mine, my hand shaking at the door knob. The room was dark and quiet. Jessica laid in bed, appearing to be asleep, so I quietly got in next to her and laid there, eyes wide open, for hours.

- - - - - - - - -

The sun came up, and I had been able to get maybe an hour of sleep. I looked over at Jessica, who to my surprise was no longer laying in bed with me. I sat up quickly, wondering if she had grabbed her bags and left in the middle of the night. They were still there in the corner of the room. I got up and checked the bathroom, but no Jessica. I went to the other side of the Jack and Jill bathroom and opened the door to peek into Kelly's room. Kelly was sitting on the edge of her bed and looked over at me when I opened the door.

"Do you know where Jessica is?" I whispered.

"No...?" She replied. "Did she say anything last night?"

"No..."

We both made our way downstairs and found mom making breakfast in the kitchen.

"Mom, have you seen Jessica?" I asked.

"Yes, she went for a run, I believe."

Kelly and I took a breath. Maybe that was a good sign? Going for a run sounded perfectly normal...something I know Jessica did often. Maybe she actually didn't see us...I hoped.

"How about dad?"

"He's in the shower. Breakfast will be ready soon!"

I walked past Kelly and uttered under my breath, "I'm going to go check his phone."

I ran down the hall to the master bedroom and quietly snuck into mom and dad's room. I could hear dad in the shower in their bathroom. I walked up to the dresser and grabbed his phone. No notifications. I knew his passcode, so I helped myself into it. No messages from Mr. Michaelson. Ok, I thought, still in the clear there. My heart was racing. What would be the first domino to fall?

As I walked back down the hallway, I just missed Jessica returning from her run and heading upstairs. I had to bite the bullet. I had to go talk to her. I walked past Kelly and we gave each other a look, as if she was saying 'good luck' to me. I thought I was about to throw up. I hadn't felt like this since I got sent to the principal's office in grade school for getting in a fight, knowing the school had called my mom.

I walked upstairs and into my room. Jessica was just pulling off her panties and was butt naked, covered in sweat, all red from her exercise. She was about to jump into the shower. She made eye contact with me and pulled her earbuds out. There was no smile...no smirk...no real emotion whatsoever. Something was different.

She walked up to me and stopped, tears forming in her eyes.

"Babe...?"

Before I could continue, she slapped me across the face. Hard. She turned and went into the bathroom and closed the door behind her. As I heard the shower turn on, I knew the storm had hit.

I slowly made my way into the bathroom, head down and full of shame.

"Baby, let me explain, please."

"Get out!" She barked. "I don't even know what to say to you!"

"I get that..."

"You get that?" She yelled. "Which part do you get? The part where my boyfriend fucks his little sister?! Or the part where my boyfriend, who I thought was my whole world, cheated on me."

I opened the shower door and grabbed her to look at me.

"You have every right to be mad...and I'm assuming...freaked out. This all just happened. I don't know how to explain it. It just...was a freak thing that just happened a couple days ago and...it's crazy! I know! And I'm sorry."

"Sorry!?" She pushed me away and closed the shower door, turning back to the stream. "Fuck you! I should leave. I should leave YOU! You know what? I should tell your fucking mom."

I saw red. It was all ending. Not just me and Jessica...but my life as I knew it. I couldn't reason with her...how could anybody reason with finding their partner fucking their sibling. This was insane! I only had one card to play, and I decided to play it. The thing Jessica couldn't resist...being dominated. I stripped down naked and got into the shower.

"Get the fuck ou...." I shoved my hand over her mouth.

"Listen to me right fucking now." I took control of her and the situation and held her firmly against the tile wall. "I'm sorry. The last 48 hours...dammit...I can't fucking explain it. Everything about my relationship with Kelly exploded into this insanity, and it drove us both wild, and I'm sorry. I know it's fucked up. And I know it's probably the thing that destroys this relationship. But..."

I stood there, still holding her against the wall, her breathing elevated and her eyes looking at me, almost scared.

"Dammit, Jessica. I don't know what to tell you...I can stop. We can stop. I'll never touch her again and I can still be yours. Or..."

Her breathing seemed to pause as she looked down. I hadn't realized it, but I was fully erect, driving my cock into her belly. She looked back up at me. I let go of her, defeated - not sure what I could, or even wanted to say.

"Or what?" She asked.

I looked deeply into her eyes. She could see the pain in mine.

"Or...you could give me a chance to explain this to you, and maybe..."

"Maybe what?" She asked, curious where I was going with this.

"...maybe share it with you."

"What do you mean?" She asked, clearly intrigued enough to hear me out.

"You know...maybe...like Lillian."

Lillian was a girl Jessica and I met at a bar some time ago. She was a senior in high school and newly 18. She had snuck into the bar with her boyfriend, who broke up with her and left her there alone. Jessica and I took her under our wing, bought her a couple more rounds to cheer her up, and eventually took her home with us. That night, we made Lillian our play thing. Something primal came out in Jessica - and myself - that was completely unspoken and never premeditated. We just both understood, in that moment, that this little innocent girl was ours to do with what we wanted. Ever since then, we referred to Lillian as our pet "unicorn"...almost as if we owned her in that moment. Jessica would tell her to perform certain acts on me. I would tell her to perform certain acts on Jessica. She was wildly obedient. That night, the three of us fucked for hours and Jessica and I used her in any and every way we wanted. It felt like we were royalty in the olden days, playing with some peasant girl we found on the side of the road...like the rules didn't apply to us. It was one of the more wild nights Jessica and I ever had together, and we often looked back on it fondly. Tragically, we never saw Lillian again after that night. She was a taste of the forbidden apple that we never found again. Jessica and I would often daydream together about finding another unicorn, someone subservient to our relationship that we could both use for our sexual desires - either together or separately. When I wanted to fuck Jessica on nights when she was distracted or not in the mood, she'd say things like 'THIS is why we need a Lillian!' In this moment with Jessica in the shower...hat in hand and tail between my legs...it was the fantasy of a 'Lillian' that was all I had to fall back on to hope this would work out.

There was a long canyon of silence before she responded.

"You want to make your sister our unicorn?"

"What if we did? Could you see past the sibling aspect? Maybe we can redefine our sibling relationship completely...make her our play thing?"

There was another large silence before Jessica reached up her hand and grabbed my hard cock, still poking into her belly. Her attitude had shifted from furious betrayal to curious arrousal.

"Show me" she said.

She stepped up on the edge of the tub and climbed up around my body. She grabbed my head by my chin, hard.

"Show me how you can make Kelly into aLillian." She looked at me with a level of severity and sternness I hadn't seen in her eyes before. "Show me how this works for BOTH of us...how this remains a secret FOREVER...and show me why I should even CONSIDER something so fucking insane!"

She reached down and pulled my cock up into her pussy and slid down on it.

"Explain it to me" she said as she fucked herself with my cock.

"What?" I asked, confused as to what the fuck was happening.

"Explain to me how this cock ended up in your sister Danny."

Was she getting off to this? Did it work? Did me offering my little sister as a pet for Jessica work? Clearly, she was mad...she didn't hide that emotion. But was she also turned on?

"I..." I paused and watched her close her eyes and get ready to get off to this story. "I saw her masturbating the other night. I went through her phone and...and I found out she's into incest...at least, it turns her on. She admitted she wanted to fuck her brother...and it turned me on to think about...and so I...snuck into her room the other night and...took her virginity."

Jessica moaned as she listened to my confession, humping and grinding on my cock. I held her up with my hands and began to give it back to her, pounding my cock in her wet pussy.

"How did it make you feel...fucking your little sister?" Her breathing picked up. "How did it feel to fuck the girl you grew up with?"

I leaned down and licked her neck and earlobe and whispered, "Fucking...alive."

"Did you cum in her?" She looked into my eyes.

I nodded, terrified, admitting what I had done.

"Did you taste her?"

I nodded again.

"What did she taste like?"

"Why don't you find out for yourself?" I replied, hoping to further plant the seed in her mind that Kelly could become her play thing too.

"Were you scared?"

"Scared?"

"To fuck your sister...? Did it make you nervous? Did it make you shake? Did you get scared?"

She kept fucking me, and I kept sliding deep inside her, feeling myself build up to an orgasm.

"It was...terrifying...at first. Then it felt...powerful."

"Do you want to fuck her in front of me?"

"Yes...I do. I really do" I said, getting closer and closer.

"Are you going to watch me fuck her? Are you going to watch me cum all over your little sister?"

"Fuck yes baby."

She let out a final moan and came all over my cock, holding in her screams so as to not alert the whole house of what was happening in the upstairs bathroom.

"Fuck Danny!" She let out. "Fuck!"

It was my turn, I grabbed her hips and adjusted her slightly to pick up my speed. I started to feel it coming and got weak in my knees.

"Oh baby! I fucking love you! Fuck. Fuck!" I started to yell, about there.

She shoved me off of her and slapped me in the face again, hard. My hard cock pumping full of blood, waiting to be brought to a climax.

"Then you fucking show me Danny" she said sternly, catching her breath. "Show me how you're going to make this happen...how you're going to make this right."

She got around me and out of the shower and grabbed a towel.

"And don't you EVER fuck another woman behind my back! You got that?!"

With that, she walked out of the bathroom and left me on the precipice of an orgasm that had been completely ruined.

"Fuck!" I shouted, frustratingly.

I grabbed my cock and pumped it vigorously until I came all over the shower floor. It was pathetic, but necessary. If this was the extent of my punishment, I was happy to accept. I just hoped there wasn't more.

----------

When I got out of the shower, dressed and downstairs, Mom, Kelly, Dad and Jessica were eating at the breakfast table. Kelly barely touched her food, likely still sick to her stomach in fear and worry. But Jessica acted totally normal, as if nothing had happened. I walked in and Kelly met my gaze immediately.

"Hey babe! Grab a plate" Jessica said with a smile. She was quite the actress.

As we ate, mom asked me to take Jessica with me to the store to pick up a few things she needed for dinner.

"You know what? Why doesn't Danny take Kelly with him, and you can show me all those old scrapbooks you were telling me about!"

Mom's eyes lit up.

"Oh that's a wonderful idea!"

Jessica knew that, based on our conversation in the shower, I had some explaining to do to Kelly, and clearly she wanted to give her and I some space to have that conversation. Dishes were cleared and coffees were finished and I grabbed my keys and Kelly and I made our way to the car. Once we were clear and out of earshot, she finally exploded in questions.

"What the fuck Danny? What happened?"

"Stay calm" I said, pulling out of our driveway. "It's all going to be ok with Jessica."

"OK?! So she didn't see us?"

"No...she saw us."

"What the fuck!" She yelled, pulling her hair and stressing out.

"But..."

"But? But what!? How are we leaving her alone with mom right now!? Isn't she going to tell her?"

"She's not going to say a thing. There's just...one small caveat."

"I'm waiting..." she said impatiently. "What? Is she blackmailing us?"

"Not exactly. Look. Do you want to keep up what you and I are doing?"

"Danny, are you serious? I think we need to focus on our lives not falling apart...and not your fucking dick. Don't you?"

"No...Kelly...listen to me. If you could, would you want to keep this up...to continue to explore this feeling?"

She stared out the windshield of the car not knowing what the hell I was talking about.

"...yes? I don't know!"

"Yes? Or you don't know?"

"Yes...of course I would. But..." I cut her off.

"Have you ever heard of a 'unicorn'?"

"A what?"

"A unicorn...being a unicorn."

"...no...?"

"It's a person...like a 3rd person...in a relationship. Sort of a submissive...sometimes submissive, I suppose...who is essentially a play thing for the couple. Like...they're a part of the couple...the relationship." I was fumbling all over my words.

"Danny, what are you trying to say?!"

"You would be Jessica and my unicorn. You would be the 3rd in our relationship."

"What?!" She yelled.

"Yeah. That's how this can continue. That's how Jessica doesn't leave me and tell mom and dad...and all my friends...and ruin our lives."

There was silence in the car. She was putting this together, quickly. It intrigued her and confused her at the same time.

"So..." she started. "She wants to watch us fuck or something?"

"Among other things."

"What kinds of other things?"

"She'd want to fuck you too. You would be her play thing as much as you'd be mine."

"Is she bi?" She asked.

"Who isn't bi?" I responded.

After some silent reflection, she added, "But what's in this for me? I'm not a fucking pet Danny."

"Kelly, you will be whatever the fuck Jessica wants you to be, or you and I will be cut off and ostracized from society...is that sinking in? You and I get to continue to explore whatever this is with each other...which I fucking want...obviously...and you also get to fuck Jessica who's hot as shit. What is the problem here?"

She looked out of the car, offended.

"Jessica wants this? Really?"

"Demands it, more like."

----------

We finished the errand and pulled back into the house. Mom and dad were sitting in the living room with Jessica, laughing and looking through photo albums and drinking cocktails very early in the day.

"Hey everyone" I said, nervously, still unsure how volatile Jessica was with this new information.

"Hi baby!" Mom shouted. "Oh honey, thank you for doing that. Can you actually put all the meat in the freezer? We're going to use it tomorrow instead."

"Oh? What are we doing tonight?" I asked.

"Well...." Mom said with a grin. "Jessica gave your dad and I a very lovely - and way too generous - Christmas gift. Your father and I are going downtown tonight to the Intercontinental for a little staycation getaway and spa treatment! So you three are on your own for dinner!"

"Is that so?" I asked, pretending to surprised by Jessica's obviously last-minute devious little plan. What did she have in mind for tonight?

"Thank you again darling" mom said to Jessica, hugging her and kissing her cheek.

"Fun..." I said, locking eyes with Jessica who gave me a very stern look.

----------

3:30 rolled around and mom and dad came out of their room with a suitcase and two big smiles.

"Ok kids, we're off! We'll be back in the morning...probably late morning. You know how your dad loves a hotel breakfast buffet!"

"Ok, have fun!" I said.

"Enjoy yourselves! Don't forget to relax and enjoy your massages!" Jessica added as she closed the door behind them.

The door closed and the house stood perfectly still. Kelly and I stood in the living room, quietly looking towards Jessica for permission to move a muscle. She pressed the door shut and slowly turned towards us with a small grin. She bolted the door locked and slowly walked past us and onto the couch. She sat down, crossed legs and made herself comfortable before letting out her first words.

"Show me" she uttered, calmly.

Kelly looked at me, confused. I just looked at her with an apologetic face and did as I was told. I turned to Kelly, grabbed her face in my hands and pulled her in for a kiss. Her eyes widened, shocked that I was doing this in front of Jessica who sat on the couch grinning, watching her boyfriend begin the process of anointing his little sister as their new unicorn. As I kissed her, I started pulling off her top. She pushed my hands away in protest, but I quickly overpowered her and before she knew it, her top was off. I then unclasped her bra and threw it to the ground. She covered her supple, young breasts quickly, ashamed of exposing herself in front of guests. As I continued kissing her, I unbuttoned her jeans and then pulled them down around her ankles. I squatted down and made her step out of them. I held her waist in my hands, her lacy thong under my fingertips, and pulled her into my face, shoving my nose in her mound and breathing in my sister's intoxicating scent. I kissed her body a few times and then slid her panties down and off. She covered her pussy with one hand while trying to cover as much of both of her breasts as she could with the other. I stood back up and looked over at Jessica, almost asking for her next wishes.
