Protector: A Billionaire Step-Brother Romance

“It’s fine,” she lied, her shining eyes meeting mine, “it’s just…well, now that I really know what Todd is like, I—” she stopped herself, biting her lip uncertainly, “No, I really shouldn’t be thinking like this on Mom’s special day.”

“Hey, you’re entitled to whatever you feel.” I sat down beside her and put an arm around her reassuringly, suspecting what was on her mind. The gesture couldn’t be seen as anything but brotherly, I figured, even if the paparazzi could get a shot at us from so far away.

“When I went in there to help her get ready a few minutes ago, she seemed anxious, but…well, not in the same way you’d expect someone to be on her wedding day, you know? Cole, I think she’s having some serious regrets. I think she’s starting to see the side of Todd that you and I know about. What if we’re the ones bringing that out in him, though?”

“No, Mackenzie,” I assured, her words having confirmed my suspicions, “That’s just what Dad is like, even if it takes some stress for him to show his true colors. If you think Julie is seeing this in him now, just be glad that it isn’t hitting her later, when they’ve got stronger ties that might make it harder for her to break away, like—” I trailed off.

“…like kids?” Mackenzie finished, looking up at me and noticing the downcast expression that had come over my face. I was quiet for a few long moments, watching a blossom gently bounce against the side of the fountain.

“It’s going to be another hour or so before the ceremony—come with me a sec, I want to show you something,” I finally said, taking her slender hand in my larger palm and bringing her up with me before heading off towards the manor.

The walk to the house felt longer than it was. The pageantry of the whole estate made everything feel even more massive than it really was, and even though the serving staff was quick to step aside for us as we made our way in, the hustle and bustle was thick in the air. Champagne and hors d’oeuvres were offered to us on actual silver platters, and we waved off beckoning calls from groups of unfamiliar relatives who were probably hoping to cozy up to us, the soon-to-be heirs to the Van der Hausen fortune. All that was assuming Dad didn’t find a way to weasel my inheritance away from me, but I wasn’t about to let that happen without a fight. If anyone deserved a pay-out, it was us.

I led Mackenzie inside the house and down the long marble hallway, and as she realized where we were going, she looked confused.

“Cole, why are we going to my room?”

I led her inside, a mix of emotions roiling in my chest. The first time I’d been in here since Chelsea passed was the first time I’d met Mackenzie, the spitting image of what Chelsea might have been at this age. The second time, it was to plant a camera in her room, looking over my shoulder to make sure I wasn’t being watched. This was the first time I was coming into this room somewhat at ease in a very long time. Though she was still confused, I kept hold of Mackenzie’s hand as I led her to her own bed and sat her down while I took a moment to really look around the room and take in the way it looked before shutting the door behind us and taking a seat beside her.

“There are a few things you should know,” I started slowly, meeting her uncertain yet loving gaze with my own steady, affectionate one. “This room, it used to belong to my sister, Chelsea.”

I watched her hand reach up to her mouth and her eyes widen as I proceeded to spill out the entire history of my family’s falling apart under Dad’s roof, and Mackenzie seemed to hold on to every last word. I told her about the late-night shouting matches between my parents while Chelsea and I hid in here, and she drew her legs up, scooting closer to me to listen. As I worked through the story of Chelsea’s illness and everything my dad didn’t do to save her, I watched tears well up in her eyes and slowly stream down her face that could have been made of porcelain. Her fists gripped the sheets of the bed as I told her everything about the affairs Dad had that I knew of, and how they unraveled the marriage and drove Mom away for good. Even though I was sure she’d picked up on the tense arrangement, I explained why I was bleeding Dad of all the money I could get from him in my apartment in the city.

By the time I finished laying out everything to her, every reason that I’d done everything I did and everything I wanted to do to keep her family from falling into the same state as mine did at Todd’s hands, Mackenzie was curled up into my arms and leaning her head against my chest. A small tear stain was on my shirt where her eye was, and she seemed to be listening to the slow, steady rhythm of my heart.

“I’m so sorry, Cole,” she whispered afterwards, turning those shining blue eyes up to me. “I had no idea that you’ve had to go through so much, and then to see it all happening over again with Mom and I in place of your mom and sister, I can’t imagine…”

I gave her a squeeze against my body, and her hand slipped around my waist, burying herself closer into me.

“Now you see why I’ve had to do what I’ve done,” I stated with finality, taking her chin in my hand and bringing my face to hers, kissing her gently on that delicate mouth of hers. “I’ve done everything I can to protect you, Kenzie, and this wedding today isn’t going to change any of that. We’re going to be step-siblings officially after today, so we’ve got to stick together if we want to help your mom through what she’s stumbled into.”

“Step-siblings,” Mackenzie echoed, the anxiety in her voice obvious as she started to move her hand away from the parts of my body it had been wandering towards. I put one of my hands over hers and brought it back. Her doe-like eyes flitted up to me, full of need.

“I never expected us to happen, Mackenzie,” I started slowly as I began to lean towards her, gently holding her frame in my hands as I leaned her back against the bed until I loomed over her, “but I love you, and I’ve never been happier to be able to keep someone so close to me safe.”

“Oh, Cole,” she breathed, “you’re the best brother I could ever want…” She paused, struggling with the words before meekly whispering out, “And I want you inside me, big brother.”

As her hand groped my crotch, I was rock-hard. My cock was stiff as I leaned over my soon-to-be sister, practically grinding up against my sibling’s pussy in her room at our own parents’ wedding.

As we sloppily worked each other’s clothes off in our effort to get naked without ripping anything, I felt more eager for her than I ever had before. I’d just spilled my heart out to her, felt so emotionally close to her, and now we wanted to feel as physically c

lose as our parents’ marriage was about to make us legally siblings. The shame of it burned fresh in my heart, and I could feel it in her, too, but that only spurred us to keep pushing…and it felt so liberating to think of her that way.

I could hear servants still going about their business outside the room. Not only servants, I realized, but relatives, too. Even as I used my mouth to pull down my sister’s panties, inhaling the scent of her needful pussy, I could just imagine the doorknob rattling, some nosy cousin or aunt sticking their head in to see Mackenzie kicking off her shoes and wrapping her naked legs around my back as I worked my stiff shaft against the outside of her cunt. How long did we spend talking? The ceremony must be coming up in a few minutes, people are going to be looking for us, and soon. I forced all of the thoughts to the back of my head, where they only fanned the passion we tore at each other with. My hand was squeezing her ass as I held her head with the other one, exploring her mouth with my tongue. She pushed her hips up into me, groaning quietly, protesting that I wasn’t in her yet and begging for her brother to stuff her. I sucked on her neck, and I wondered if I would leave a mark that everyone would know she didn’t have before. As we pressed close together, Mackenzie’s moans grew more desirous and louder, as if she was subconsciously threatening to expose us if I didn’t fill her up. I knew she wouldn’t dare, knew that I could quiet her at the slightest “shush,” but part of me almost wanted someone to see us, to know that we weren’t going to be cowed by being under Todd’s roof.

Above all, I just wanted Mackenzie.

Her hands groped my thick, muscled arms as I turned her over, fingering her clit as I got my cock ready to plunge into her desperate cunt. As I did, I wondered if the wedding ceremony was already going on outside. The vows could have already been exchanged, and I could be about to plunge myself into the folds of my own gorgeous sister. I felt my crown throb, and I knew that I wanted to feel my new sister’s pussy tight around my shaft.

I let a careless moan of pleasure escape me as my cock slid into her soaking-wet pussy, her ass cheeks pressing up against my groin as I shoved my full length into her. I started to move my hips slowly, letting both of us savor the feeling of my shaft rubbing the inside of her, making each thrust last a moment as I gently pushed into her. The eagerness she pushed back up against me with as I heard her own gasps told me she needed more, though, and soon. I couldn’t deny her—I was her brother, after all.

“Ohhhh fuck, give it to me, big brother,” she begged, knees digging into her mattress while I pounded her from behind. What if someone heard that? The thought made my cock harden all the more, and I could feel Mackenzie shudder in pleasure under me. My thrusting in and out was making the bed creak. If there was anyone outside, they were sure to be hearing something coming from the bedroom.

I pulled myself out and flipped Mackenzie over, stuffing my cock back into her pussy and resuming the momentum as before, taking long thrusts in and out, almost pulling all the way out with each stroke while my mouth sucked at her nipples.

“I want to make you feel like you deserve, little sis,” I whispered between mouthfuls of my sister’s breasts. She was sprawling herself out, stretching her neck as if beckoning me to bite it. Her cunt tightened at the mention of her relation to me, and she gasped.

“Don’t stop!”
