Chapter 10

“What did you say?” I was flabbergasted, and all my sleepiness had vanished.

“I said the only men who will be using me are you and dad.”

“That’s what I thought you said, and you’d better start explaining.”

“Okay ... but it’s not a short story.”

“We have lots of time.” My intention to take a shower had completely disappeared; this revelation was the only thing I was interested in.

“I was sunning on the deck when my AirPods died, so I went inside to get my headset. When I got upstairs, I overheard mom and dad in their bedroom; he was spanking her and she was calling him Daddy, and then I heard them having sex.”

“You’re joking.”

“No, that’s what was happening. Then later, dad went golfing, I took his car into town and had an accident, so, when he got home, he saw the damage and spanked me. I don’t know why, but being spanked turned me on something fierce; it must be genetic, because I apparently had the same reaction as mom does.”

“This is unbelievable.”

“Believe it. Not only did dad spank me, he had me blow him to show him my... appreciation for the spanking.”

“You gave our father a blow job?”

“Yes, and it may not surprise you to learn that it turned me on even more.”

“Based on what you’ve done, and we’ve done, both before and during this trip, I guess I’m not surprised by anything you’ve done, little sister.”

“Well, it gets even more interesting. Dad talked on the phone with mom and it was obvious that she’d known in advance what he was going to try to do; it seems the accident was just the excuse he needed to get things started. After that phone conversation, he and I had sex.”

“Weren’t you worried about getting pregnant? Not just with him, but when you’d had sex before?”

“No, because one day, when I had just turned sixteen, I was moaning the name of my then-boyfriend while I was jilling off and mom overheard me. That led to a talk and a visit to the doctor to get me on the pill. She told the doc it was to regulate my periods, but that wasn’t the real reason; based on our talk, mom figured I was going to start having sex pretty soon and wanted me protected from pregnancy.”

“Was she right?”

“Yes, after a year of fooling around I gave up my virginity when I turned seventeen.”

“Okay, so what happened when Mom came home?”

“Things got even more interesting. It’s obvious that you inherited some of dad’s dominance and that I’m submissive, like mom is with him and I’m now with you. What surprised me was how dominant mom was with me; she made me admit everything I’d done with dad and then she dominated me in some girl-girl action.”

“So mom submits to dad, but she was different with you?”

“Yeah, she definitely was.” Pam gave me a sly smile. “You may not have noticed, but mom’s got a pretty hot body herself.”

“I don’t think of our mother that way.” That was a lie. A lot of boys fantasize about their mothers, and I was no exception. She looked like an older, more mature version of my sister, and I’d thought about her ever since I started jerking off.

“Well, maybe now you should. Maybe that man-of-the-house stuff she’s been spouting has more than one meaning.”

“I have to think about that. What happened next with you?”

“The next evening, mom helped me prepare myself and then participated when dad took my ass.”

“Our mother helped you get ready for anal sex with our father?” This was getting more and more bizarre.

“Yep, she did, and then, after dad fucked my ass and made me come a ton, per one of dad’s rules she ate me out to swallow all of his cum.”

“So now you’re dad’s little slut as well as mine?”

“Yes, Alex, that’s how it is. I have no idea how mom will be with me in the future; when she was helping me get ready for dad it was like she was following his orders, not dominating me at all.”

“This is all so unbelievable.”

“I know, but it’s how things are. The real question is how you’re going to be with our parents when we get home. Dad’s off on a two-week business trip, so it’ll be just you, me, and mom, tonight and for the next few days.”

“Like I said, I’m going to have to think about that. Let’s get some sleep.”

We got up the next morning, brushed our teeth, and then showered together. Despite everything that we’d said and done the previous day, I wanted to confirm the changed nature of my relationship with my sister. So, after we started washing ourselves, I tilted her face up and kissed her. She responded enthusiastically, parting her lips to accept my tongue into her mouth, so I began touching her body, running my hands over her back and then squeezing both of her breasts. She moaned and kissed me harder, her nipples becoming erect under my palms, and she pushed her pubes against my growing erection.

I moved my hands to her shoulders and pressed down firmly, and there was absolutely no resistance. “Yes, Sir,” she whispered, and then she sank gracefully to her knees. The warm water streamed down my body as she took my semi-hard cock into her mouth and made it much harder. She began bobbing up and down, and before long I was on the edge. I pushed my fingers into her long wet hair and held her head still; I gave her no other signal, I just shot bursts of cum onto her tongue and watched her throat move as she swallowed my seed.

When I finished coming, I withdrew my cock, then reached down and slid my middle finger through her lower lips. She was slippery wet, and it wasn’t water. “You’re all ready,” I said.

“Yes, Alex,” she replied. “After last night, I knew I was yours, and you controlling me, using me like that, making me serve your pleasure, was a huge turn-on.” She hesitated, then continued. “Daddy told me I was his slut and I was to always be ready for him, and now I’m your slut as well.”

I was intensely pleased that I had confirmed the way things were going to be between us. I stroked her clit and her whole body shuddered. “Come for me,” I commanded, and then, just that quickly, she exploded in orgasm, and I had to wrap my other arm around her waist to keep her from falling as her knees gave way. I held her body against mine until she was able to stand; she tilted her face up and kissed me, her lips pressed tight against mine and her mouth wide open to accept the invasion of my tongue. We stood there for a minute, and then I put my hands on her hips and gently pushed her away.

“Thank you, Sir.”

I shut off the water and we got out of the shower and dried off. Then weheaded back to the bedroom to dress for the long drive home. I decided to push forward in another way. “Shorts and a tank top, no bra,” I directed, “and those high heels you wore last night.”

“That’s a really slutty look,” she said.

“You’re my slut, so I think you should look the part.”

She smiled. “Whatever you say, Big Brother.”

She dressed as I’d specified, and she really did look hot. The tank top highlighted the shape of her breasts and her nipples wer poking into the fabric. Her amazing ass filled the shorts to perfection, and the high heels gave her calves great definition and changed her walk into a hip-swaying delight.

“You look fantastic,” I told her.

She pirouetted on her toes, then grinned at me and wiggled her body sexily. “You like this slutty look, Big Bro?”

“You look crazy hot, and those heels make your legs look fabulous. You’re gonna drive the truckers nuts when we make pit stops.”

“I’m glad you like them, because dad likes to see mom and me in high heels too.”

“He does, does he?”

“Yes, that’s another of his rules.”

That’s interesting; maybe I inherited more of my father’s interests than I knew about. I wonder what else he likes to do with mom besides spanking and fucking her. But I had to shelve that thought; it was time to head south. “I’ll think about that, but for now let’s get going.”

We grabbed our bags and headed downstairs to check out of the hotel. After that, we loaded the car and started on our way.

The long drive was quiet and peaceful. As the miles rolled by, each of us was lost in our own thoughts, and we didn’t have to say anything to feel comfortable in each other’s presence. When we stopped for gas mid-afternoon in North jersey, I texted our mother to let her know our ETA, and she replied that dinner would be waiting when we arrived.

I was a bit anxious about how she might react to how Pam was dressed, but I wasn’t about to change my newly awakened dominant attitude towards my sister. Then I got some welcome reassurance; as I was buckling my seat belt, I glanced at Pam. “Last leg,” I said, and she gave me a big grin.

“There are five things I think you should keep in mind when we get home,” she told me.

“What things?”

“Dad called mom a slut, mom said you were the man of the house while dad’s away, and dad told me mom likes it rough.”

“What else?”

“When the three of us were together, dad called mom Mandy; that may be some kind of signal to her.

“You said five things.”

“Dad has a riding crop somewhere in their bedroom.”

Those were five very significant things, and I resolved to let the chips fall however they would.

I parked in the driveway of our house, and Pam and I unloaded our stuff from the trunk and went in the front door. Mom was waiting for us in the foyer; she must have been watching for our arrival. Her eyes widened as she took in Pam’s appearance, and then she smiled at her. “Apparently your relationship with your father isn’t the only relationship you’ve been working on.”

Pam smiled back. “No, I guess it isn’t. Alex and I have reached a new... understanding about how we’ll... interact with each other.”
