Chapter 9

I stood under the shower’s spray, washing the remnants of my cum off my body, and reflected on my changed relationship with my sister. It was clear that Pam was prepared to cross lines all over the place, but I still didn’t know why. What were her reasons or her motivations? Half of me expected her to stop at any point and yell Tricked you! The other half felt like she’d let me do whatever I wanted to her, especially if I spanked her first. The constraint but she’s my sister was pretty much gone; my mental barriers had been gradually torn down. We were both adults, and no one knew us here. We were in the privacy of our own room, with no chance that someone might disturb us. I guess I’ve come around to Pam’s way of thinking, one step at a time.

I killed the shower and dried myself, only then realizing that the only clothes I had in the bathroom were dirty. I knotted the towel around my waist and opened the door. Pam was still where I’d left her, lying naked on the bed.

“Mmm, hot look, Big Bro,” she said. I stood and gazed at her nakedness, thinking the same.

She rose smoothly, smiling, cat-like in her grace, and padded past me. I was getting used to her displays of casual nudity, but that didn’t mean I wasn’t going to look. I heard her start the shower and I fished out a clean pair of boxers, lay down on the bed, and picked up my Kindle.

She walked out of the bathroom, naked, a few minutes later. “I’m gonna go look around the convention. Do you want to come?” she said as she fished for clothes through her bag. “I’ll get you a pass.”

“Not really my thing, Sis. I’ll probably hang around here, or maybe go for a walk.”

“You sure you’ll be okay?” She’d pulled out a pastel pink outfit that seemed far too small to wear in public, but it suited the theme of the convention.

“I’ll be fine.” I’d be bored, but what else was there to do? Taking another trip into Boston would be a lot of effort.

“Well, it’s the last day,” she said as she stepped into a pair of lacy white panties. “So I want to get as much done as I can.” A matching white bra followed, with a white crop-top and then the pink outfit – skirt and jacket, both very, very short. She looked innocent, demure, and kinky all at once.

“You be careful not to get the wrong attention, dressed like that,” I told her.

She smiled at me as she sat on the chair and buckled the ankle straps on her matching pink stiletto heels. “It’s okay, Big Bro. It’s a public event, there’s security everywhere, I won’t be leaving the building, and the only person who gets to play with me is you.”

“Just ... be careful.”

“Sure. Back when it finishes? Probably about six.”

“Okay.” I glanced at the clock; it was only just after nine. Maybe I’d go find some breakfast.

“I’ll leave you the room key,” she said, then paused at the door and glanced back at me. “Gotta say, it’s tough to leave you, lying mostly naked on the bed.” She made a mock sigh. “Still, a girl’s gotta do what a girl came to do.”

She smiled again and slipped out the door, closing it behind her.

I pulled on some clothes and went down for breakfast. After eating, I went out for a walk, but I got bored and went back to our room. I sat in the chair and read for a while, then glanced at the clock. It read almost two; it would be another four hours before Pam was done. But then, while I was trying to figure out what to do, there was a knock on the door.

I’d partly undressed when I came back to the room and was wearing only boxers and a T-shirt. So I opened the door a crack, keeping myself behind it, and then opened it wider when I saw it was Pam. “Here for a break?” I asked, letting her in.

“Here for good,” she said as she entered.

I closed the door behind her. “I thought you were all in to this thing.”

“Yeah, so did I,” she said as she bent to unstrap her shoes, giving me a great view of her ass as she did. “But to be honest, Big Bro, I think I’ve outgrown it.”

I chuckled. “No shit. I could’ve told you that before we left home.”

She straightened, turning to face me. “Well, you would have been right. But I wanted to get away, and then I wanted to be alone with you, so the trip hasn’t been a complete waste, has it?” She pulled the pink jacket off and dropped it on her bag.

“No, it hasn’t,” I agreed as I walked back to the chair I’d been sitting in.

“I’m gonna take a shower,” she said, drawing my eyes to her again. She was unfastening the pink skirt and letting it fall. “I need to wash the convention off of me.”

I watched, saying nothing, as she pulled her crop-top off, leaving her in just her underwear. I knew she’d been walking around the convention looking like that and getting about a million stares, but I, her brother, was the one who got to see her take it all off. I’d watched her strip a few times, now, but, if she wanted to show me again, I wasn’t going to argue.

She reached behind her back, unclasped her bra, and let it fall. “You do have amazing breasts,” I said.

She looked at me and smiled. “Do you really think so?” she asked, pulling her shoulders back to better show them to me.

“Absolutely,” I said. “Your breasts are perfection.”

She smiled again and turned away. “What about my ass?” she asked, pushing it out slightly for my inspection.

“That too.” Only a couple of days ago, I would’ve felt awkward even looking at her ass, but now I was okay discussing it with her, like it was a piece of art or something. Well, it was a piece of art – beautiful, living art.

She looked at me over her shoulder. “Ass or breasts?”

“How do you expect me to tell when one is bare and the other is clothed?”

She chuckled, a deep, throaty chuckle. “That’s fair, but I’m going to take a shower first. Then you can examine all of me to your heart’s content.”

She walked into the bathroom, closing the door this time, and I stared blankly at my Kindle. I couldn’t help but think that our dynamic had really changed, and I found myself wondering again where this level of intimacy had come from. By the time the bathroom door opened again, I thought I had my answer. She came out wearing just a towel, wrapped around her tightly.

“I have a question,” I said before she had a chance to say anything.

“Okay. Truth or Dare, then,” she announced playfully, coming over to sit on the edge of the bed and tucking the towel around her thighs.

I cocked my head, looking at her. “Sounds dangerous.”

“Probably.”

“I was thinking, while you were at the convention, and again while you were showering, wondering when all this...” I made a gesture with my hand that covered the scantily-clad form of my little sister, “ ... started. Was it when I spanked you the first time over you trying to steal my car?”

“Borrow,” she said with a smile. “Yes, I suppose you could say that. I ... I liked it when you spanked me. It showed me a side to you I hadn’t known existed. I like your dominance, Big Brother.” She smiled again. “My turn. Truth or Dare?”

“Truth.”

“I knew you’d say that. So tell me truthfully; did you like spanking me?”

The time for denial was long past, and she already knew the answer, anyway. “Yes, I did. Why do you like being spanked?”

“Don’t I get to choose Truth or Dare?”

“Not this time.”

She looked thoughtful. “Ummm ... I like the dominance, as I said. And I like the intimacy, the sensuality, of it. It turns me on. And I like the feel of your hand on my ass.”

It made a lot of sense when she explained it like that. I realized I’d maybe been hasty when I more-or-less accused her of being fucked up for liking it. Besides, from what I’d read, a lot of people liked it – and lots of people liked kinkier things than that, too.

“You pushed me into it the second time, didn’t you?”

She nodded. “I did. I wanted to know if you’d do it again or if it was a fluke. But it’s my turn. Truth or Dare?”

“Truth.”

“Did it turn you on? Spanking me, I mean?”

I smiled. “Yes, it did.”

She shook her head. “I’m glad it turned you on.” She raised one eyebrow. “I’ll take a dare.”

“You’ve already shown me your breasts. I dare you to show me your ass.”

“Easy. How long?”

Oh, yeah. People usually put time limits on these things when they played. I’d never actually played Truth or Dare before, not like this, anyway. “Thirty seconds.”

She reached for her phone and set a timer, her lips twitching in amusement. Then she stood, still in her towel. I figured she’d dump the towel, given how quick she’d been to be nude at other times, but, now that we were playing, she seemed to want to tease. She turned away, leaning forward to support herself on the bed and sticking her ass out toward me, then reached back and slowly inched up the towel.

Bit by luscious bit, her fantastic ass came into view until the towel was so high it was up over her waist. I feasted my eyes on the delightful curve of her butt, the intriguing slit that ran between her cheeks, and the hint of her perfectly smooth pussy that I could just see below. Then her phone beeped and the towel dropped down again, covering the beauty she had briefly shared with me.

“It is a fantastic ass,” I conceded.

“So, ass or breasts?” she asked, sitting back down on the bed.

“Ass. Has to be ass. I love your breasts, too, but your ass is to die for.”

She giggled. “My brother is an ass-man. I never knew that before. Truth or Dare?”

“Dare, I suppose.” I had no idea what she’d ask of me, only that the game called for a dare.

“Take your T-shirt off.”

I raised an eyebrow at the simplicity of her request, but I leaned forward and pulled it off, bunching it up and throwing it on top of my bag. “Are you so easily pleased?”

“I like seeing you naked,” she said, running her eyes over me.

I wasn’t going to complain. “Your turn.”

“I’m okay with another Dare.”

I’d figured she would be. The obvious choice, after the T-shirt thing, was to get her to lose the towel, but I didn’t want to be so predictable. “I dare you to masturbate in front of me for one minute without coming.”

“Mmm, I like it,” she purred. She slipped a hand down between her legs, turning sideways and raising her thigh so I couldn’t see what she was doing. “Are you going to time me?”

“Yes. Are you going to let me see?”

“No. That wasn’t part of the dare.”

Damn. I’ll have to be more specific in the future.

She kept her eyes on me as her hand began to move between her legs. It was incredibly erotic, watching my sister masturbate in front of me, and especially so because I’d dared her to. It was also incredibly powerful.

She chewed her lip and her eyelids fluttered as her pleasure grew. She was beginning to squirm, her hips moving as she stroked herself. “I didn’t think it was going to be a problem, not coming within the minute,” she said around soft gasps, “but with you watching me... fuck, Alex, this is intense.”

Her face was reflecting all sorts of emotions and her lower lip was beginning to tremble. I glanced down at the stopwatch I’d started on my phone and watched as the seconds counted into the fifties. I really liked the idea of her having to edge for me. “Time,” I said softly.

She slumped on the bed with a small gasp, then gave me a small smile. “That was hot.”

“You’re hot.”

Her smile widened and she lifted her hand to her mouth, slowly sucking her fingers clean of her own arousal. “Truth or Dare?”

“I’ll take another Truth,” I said, determined to keep my boxers on for a few more minutes.

“Hmm, a Truth,” she said contemplatively, tapping her fingertips against her chin. “Are you looking forward to spanking me again?”

“You’re making this too easy. First the shirt, now this. Yes, I am. You know I am.”

“Yes,” she said, “I know you are. My turn for a Truth.”

I regarded her. “What wouldn’t you do for me?”

She lowered her eyes, but a playful smile flirted with her lips. “I thought you knew that by now, Big Bro. There’s nothing I wouldn’t do for you.”

“Especially if I spanked you first, huh?”

She smiled. “Yes, especially then. But I’ve already promised I’ll obey you.”

“Why?” I asked, and in that moment it was the only Truth that mattered.

“Because I love you, Alex. I’ve always loved you, and then you went and spanked me, and just like that my love became lust, too.” Her voice was soft, and I could hear the sincerity in her tone. “I’d always have done anything for you, but, once you’d pinned me down and showed me how you could dominate me, I wanted to do anything for you.”

“That was why you stripped off your bikini in the kitchen, why you let me into your room while you were naked, and why you showed me your body in my room,” I said, finally fully understanding what had really been happening and why. “You were... offering yourself?”

“Yes,” she said, and then she bit her lip nervously, fiddling with the bottom edge of her towel. I didn’t say anything; I thought there could be more she would say, and the seconds ticked by until she spoke again. “I wanted to give you everything I had, but you seemed to see me only as your sister. I knew you’d have to see me as a woman, first, so I ... I showed you my body. I ... I hoped you’d like it, that maybe you’d want it.”

“So you’re my little slut sister?”

“Yes,” she said, nodding her head, her eyes wide and full of hope as she looked at me.

“You’ll do whatever I tell you to?”

“Anything you want,” she breathed.

“Suck my cock?”

“Whenever you tell me to,” she said, licking her lips. Her eyes flicked down toward my boxers.

“Present your bare ass for a spanking?”

“Oh, God, Alex ... yes.” She shuddered at my words.

There was one more thing I needed to know. “Let me fuck you?” I held my breath.

“Fuck, yes. Any hole you want.”

Those four words speared straight into me. Any hole you want. I’d fantasized, more times than I could count, that some day a girl would say those words to me, and it was Pam, my sister, who’d said it. This was unreal. She was my sister, she loved me, and she said she’d do literally anything for me.

“Stand up,” I said, my voice as neutral as I could make it as I tried to hide the lust I was feeling.

“Yes, Alex,” she said, rising swiftly.

“You don’t need the towel any more.”

She pulled it free and let it drop to the bed behind her, then clasped her hands behind her back and stood naked before me. There were no games now.

“I trust you know this behavior is totally unacceptable,” I said, making my voice as stern as I could.

She quivered, her eyes dropping to the floor. “I’m sorry,” she whispered. “I just wanted–”

“Quiet,” I said, interrupting her. “You’re going to have to be punished. Turn around; it’s time for your spanking.”

Her head came up. “Yes, Alex.”

I watched her as she faced around, then rose from my chair and stepped up beside her. “Bend for me,” I said, and I put my hand in the small of her back.

She bent forward over the bed, her ass coming up, as though in offering. She rested on her forearms, keeping her legs straight and presenting herself to me. I let my fingers slide down over the top of her ass.
