Original Sin

The next morning after breakfast, we all met down at the beach. There were lounge chairs that belonged to the hotel, and to our surprise, we found several open ones next to each other. I was in the middle of my book, when I caught a glimpse of Ashley walking back from the water. (She had gone straight to the ocean when we got to the beach.) Her bathing suit was much more conservative than the skimpy bikini I still imagined her in from time to time, but it didn't matter; the one-piece may have covered up her midriff, but the only way to hide her curvaceous figure would be to wear a potato sack. As she walked up to where we were sitting, she glanced over at me with a smirk. Busted.

After drying off, Ashley announced that she was going to go to the restroom and get something to drink. After about a half-hour, my mother asked, "Where's your sister?"

"I don't know'" I replied, "Let me see." I pulled out my phone and sent her a text.

*Where are u? Mom's asking.*

*In my room. Tell her I got tired of the sun.*

*What are u doing?* *I just took a shower. But that's not all...I think I need to be punished. Do u believe in corporal punishment?*

"She's up in her room," I answered. "She said she was tired of being in the sun. I am too," I lied, "what time do you want to meet for lunch?"

"How about 12:30," my dad said.

I nodded and made my way up to the hotel. As I rode up the elevator, my body tingled with anticipation. Did she bring the flogger with her, I wondered. If not, what would I use to punish her? I may have to spank her, I thought, chuckling in both amusement and nervous anticipation.

My heart pounded in my chest as I knocked on her door. A few beats of my heart later and the door opened. I stood still, momentarily frozen in the hallway as Ashley wore a white, terry cloth hotel robe, her long dark hair in a ponytail. I crossed the threshold, following my sister into the room as she sat on the bed.

I was still trying to figure out exactly what I was going to do when she said, "I've been so bad, Michael. I knew I would; that's why I brought this along." She reached into the top drawer of the nightstand. Sitting next to the King James Bible was the leather flogger. She took it in her hand, almost caressingly, and held it out for me. Without hesitation, I took it.

Feeling more sure of myself, I said, "Take off your robe and tell me why you should be punished."

Ashley smiled, her cheeks becoming flush with embarrassment, arousal, or perhaps both. She slipped off the robe, letting it fall at her feet. My manhood instantly began to swell at the sight of her curves. She wore matching white lace bra and panties, the purchase of which she obviously kept from our parents.

She crawled on the bed and got on her hands and knees facing the headboard. "When I was down at the beach, the mixture of the heat of the sun and the way men were staring at me made me so horny, I had to touch myself before I lost my mind."

"What did you do when you got up here?"

"I started touching myself, but I was so hot that I got a better idea. So, I got in the shower and turned the shower head to the massage mode."

At this point, I maneuvered into an advantageous position and struck her in the middle of her ass. She jumped in reaction but then settled back, anticipating the next blow.

"I moved so that the beads of water hit my clit." She closed her eyes as if reliving the moment. "God, it felt so good...the steady rhythm of the water hitting my pussy over and over and over..."

WHACK! I struck her across the small of her back.

WHACK! Again across her beautiful, round butt.

"I stuck a finger in my pussy while the water massaged my clit. It didn't take long to come once I started fingering myself."

Whack! Whack! Whack! I started flogging her ass in a steady, rhythmic tempo that had her swaying back and forth, anticipating the blows.

"I came so hard," she continued in a hoarse voice, "I thought I was going to explode in a million pieces...that's when you texted me, and I needed you to punish me."

I moved closer to her as I continued to punish her with the leather flogger. I could smell her scent, and it made my cock stiff in my shorts. Her skin was beat red with marks all along her round ass cheeks. I stopped and allowed her to catch her breath.

"You're enjoying your punishment a little too much," I said with a smirk "I'm going to have to up the ante next time."

With that, I turned and left, my raging hard-on aching in my shorts. I checked the clock; it was noon. I went straight to the bathroom, dropped my shorts to my ankles, and made myself come so hard, I saw stars. That night, when I had time to think, I wondered how far we were willing to go. I said I would "up the ante" but what was I willing to do? Utilize other instruments of control or pain? Tie her to the bed and punish her as she lay helpless? (I kind of liked that idea.). As I drifted off to sleep, I made a mental checklist of the things I would need if I was going to take this to the next level.

* * * *

The next morning, after having breakfast, we decided we were going to go mini-golfing before it got too hot. Despite me and my sister's protests, we actually had a fun time. The course was only a few blocks from the hotel, so when we were done, I said that I would meet everyone for lunch but I wanted to walk along the boardwalk. I used that time to get a few things for later; a store a few blocks from the hotel proved to be very useful.

Between the time we hung out at the beach after lunch to dinner was the opportune time to act. People were generally not in their rooms during that time of day, allowing for a little more privacy. Ashley and I were sitting next to each other on the beach when I sent her a text.

*Go up to your room and get ready.*

*For what?*

*Your daily penance.*

Ashley looked at me and smiled. "I'm going inside for a bit," she announced.

I couldn't help but turn my head to watch Ashley saunter up to the the hotel, her ass swaying with an obvious flair that made me grab my towel and toss it over my bathing suit.

About 15 minutes later, I excused myself and walked up to my room. Ashley and I had already crossed a line. How many more would we be willing to cross? I couldn't answer that question for myself, let alone for Ashley. What I did know for sure was what I was willing to do today. I stopped by my room, grabbed the bag, then knocked on her door.

Ashley opened the door, looked into my eyes, looked down at the bag in my hand, then back up at me. Having control of the situation gave me a confidence I had not had previously. I stepped into her room, placed the Do Not Disturb sign on the door, and latched the safety lock. This last action elicited a slight grin from my sister.

"What do you have in store for me?" she asked. "I actually haven't touched myself today. Do I still need to be punished?"

Knowing what I was about to say, I had a sense of anticipation and anxiety. "In order to properly punish you, I need to see you committing the act."

"Michael!" she exclaimed in a surprised tone.

"Show me how you touch yourself."

As the words came out of my mouth, part of me wanted to desperately pull them back. But, after Ashley's initial look of surprise, another look came over her beautiful face - lust.

Her eyes transfixed on me, Ashley untied the knot on her robe and let it fall to the ground. In my mind, the sound of her robe hitting the floor was deafening. She wore a light pink bra and panties set, the top of her large breasts almost busting out of her bra. As she turned to get on the bed, I caught a glimpse of her nipples, hard and erect. I placed the bag next to the nearby chair and sat down.

Ashley cupped her breasts in her hands, teasing them; then took her nipples between her fingers and sighed as she pinched them between her thumb and forefinger. After propping herself up on a pillow, she continued to play with her nipples with one hand while her other hand drifted agonizingly slow down her perfectly shaped body until her fingers hovered over her panty-covered sex. I shifted in my seat to alleviate the pressure mounting in my shorts; this elicited a smile from Ashley. She knew what she was doing to me and she loved it.

She spread her legs wide, giving me a perfect view of her body. Lying back on a pillow, Ashley traced along the length of her pussy lips, occasionally focusing on her clit. As she became more aroused, her hips began to gyrate as if they had a mind of their own. Seemingly unable to wait any longer, she slipped her hand underneath the thin fabric of her panties.

"Ohhh," she murmured, as her fingers began circling her button.

She pulled her hand away momentarily to lick her fingers before slipping them back under her panties.

"Mmmmm," she cooed, "feels soooo good."

I had a straight-shot view of my sister's crotch, her toned legs trembling with arousal, her hand working deliberately as her moans became louder with each passing minute. Not wanting her to orgasm too soon, I stood and walked to the side of the bed. At first, she didn't realize I was there as she continued to pleasure herself. She was truly incredible. Ashley's curvaceous body was beautifully toned; her left breast had been freed from her bra as she cupped in her hand; her long dark hair was splayed out on the bed, framing her face, which was frozen in a combination of pleasure and agony. I could have watched her all day.

After snapping myself out of my reverie, I reach out to my sister and place a hand on her wrist, momentarily stopping her momentum. Her eyes shot open in surprise as she drew in a quick, sharp breath.

"I think that's enough for the moment," I said, a slight quiver in my voice. "Stand up and clasp your arms behind your back."

Without a word, but with a mischievous grin, she complied. I took out the the silk rope that I had purchased earlier and, with only a little bit of effort, secured her hands behind her back, resulting in an exaggerated, upright posture that pushed her breasts out from her body. Before Ashley could say anything, I placed a sleep mask over her eyes, blindfolding her, and told her to spread her legs.

I maneuvered her away from the bed so that she stood in the middle of the room, vulnerable and open to what I had planned next. I went to her nightstand and retrieved the flogger. Since we were at the beach every day, I had to be careful not to use it too much so as to not leave any lasting marks; but that didn't mean I couldn't use it for a little while. Without warning, I struck her on her panty-covered, perfectly shaped ass. Ashley jumped and whimpered in reaction. I struck her on her left butt cheek and then her right, alternating between the two in quick succession as she struggled to maintain her balance.

"Do you want me to stop?" I asked, knowing her answer.

Ashley swallowed and replied, "No."

"Keep your legs spread," I said, moving in front of her as she turned her head trying to figure out where I was.

Ashley often wore bras that unclasped in the front; I had noticed earlier that this was true of the one she was currently wearing. I unclasped it and pushed the straps down her arms, providing me full access to her magnificent tits.

"Wha-what are you doing?"

I lightly tapped her sex with the flogger, the leather strands teasing her clit. "I thought you didn't want me to stop."

"I don't."

"Do you trust me to go only as far as I know you're willing?"

"Yes," she replied in whisper.

After giving her panties one more tap, I whipped the leather across her left breast and then her right. Ashley bit her lip, holding her breath as she took the punishment. Ensuring that I indeed wouldn't go further than she was willing, I said, "I understand that safe words are often used in situations like this. If you want me to stop what I'm doing at any time - and this is for now and in the future - say the word catapult. Okay?

"Okay," she replied, swallowing hard.

After a couple more strikes to her tits, I took a step back to admire my sister. She was the embodiment of sex - her hands tied behind her back, Ashley continued to stand with her legs spread wide. Her large D-cup breasts hung heavily but firmly, the nipples hard, a few red marks along the underside where I had focused my attention. Her breathing was shallow and erratic, making her chest move up and down in a way that was incredibly erotic. Her panties were clearly damp, and I longed to feel her wetness.

Reaching into my bag, I pulled out two clothes pins. My hand trembled ever-so-slight as I reached out and cupped her left tit in my hand. Ashley took a half a step back, taking in a sharp breath; but instead of protesting, she squared her hips and stood tall, her lips parted as I took her in my hand. She felt amazing. It was surprising how firm yet soft it was, and I couldn't help but moan aloud as I played with it. I felt my cock once again swell in my shorts, and I shifted to accommodate it's size. Ashley gasped as I ran my thumb across the nipple, making it erect. I then took it between my fingers and squeezed, gently at first, and then with more pressure.

"Ugh," she grunted in response.

Next, I took one of the clothes pins and slowly closed it around the erect nipple.

"Ow!" she exclaimed.

I watched her reactions carefully, looking for a sign that she wanted me to stop. After the initial shock, she steadied herself. Still having the green light, I repeated the process with her right breast; I then stood back and admired her once again. Reflexively, I touched myself through my shorts. I couldn't think of a time my cock had felt so hard. Turning her around, I untied her hands and had her lean over the bed, placing her hands on the mattress to brace herself. Coming up behind her, I ached to press my manhood against her, but controlled the urge to do so; instead, I spanked her across her right cheek, then her left. Ashley whimpered with each stroke of my hand.

Right.

Left.

Right.

Left.

With each strike her grunts grew louder and louder. Her skin felt incredible under my touch. Just when I thought she couldn't take another blow, I said, "Touch yourself."

Ashley immediately began rubbing her clit with her right hand while still leaning on her left. After a minute or so, I began spanking her again - not as hard as before, but more consistently.

"Oh, fuck!" she exclaimed. "Yes...Yes...Yes," she intoned after each slap. "Oh, my God; Oh, my God; Oh, my God!"

Ashley's legs were quivering when I took her by the shoulders and held her to me, her back against my chest, my right arm around her waist, and my left around her neck.

"Don't stop," I whispered in her ear, "I want to watch you come."

"Oh, God, Michael....fuck!"

She pressed her body against mine, her ass grinding against my stiff manhood. When Ashley felt the state of my arousal, she lost it - she pushed her panties down to her knees and slipped two fingers inside her pussy while continuing to rub her clit at a feverish pace. Sounds of agony and desperation escaped her lips as I held her tight, lost in the moment. I felt both in control and completely helpless at the same time. Ashley stiffened momentarily before letting out a low, guttural groan. As she did this, I released the clothes pins from her nipples, causing her to cry out as her orgasm hit her. I held her tight as the waves of pleasure pounded her body. When they had finally subsided, I let her fall to the bed, spent and glistening with perspiration.

A few moments passed that felt like an eternity before she spoke. She looked down at my crotch and I couldn't help but follow her eyes. My bathing suit was having a terrible time concealing my arousal.

"Looks like you enjoyed the show," she said without a hint of humor.

"I have some business to take care of, thanks to you," I replied. Conflicted but still having my wits about me, I walked over to her and kissed her on the forehead. "I love you, sis."

"I love you," she replied.

As I opened the door to leave, she started, "Michael - never mind; I'll see you at dinner."

As I got myself off, there was only one image in my fantasy - my sister sucking my cock. And, as I exploded with a crippling orgasm, I imagined my sister on her knees, swallowing my load.

The following day, we didn't have an opportunity to play as our father had planned a full day of tourist activities for us. The next day as I laid on the lounge chair next to my sister, I hadn't made up my mind what I was going to do to her; just that there was no doubt in my mind that at some point this afternoon, we would have an opportunity. I placed my book to the side, closed my eyes, and got lost in thought.

At around two o'clock, I excused myself and went up to my room to take a shower. I texted Ashley and told her to shower, dress, and come to my room. I was prepared for her when she knocked at my door.

Ashley wore a light blue tank top that was tasteful enough to pass our parent's inspection, but with her curves, it bordered on flirtatious. Her shorts accentuated her butt, which I caught a wonderful view of as she stepped into the room.

"Strip down to your panties," I said as evenly as I could despite my racing heart. With each step we'd taken, we'd gotten more and more bold. I wondered where the line was because I wasn't sure where to stop or if I'd want to.

Ashley hesitated momentarily, then looking straight into my eyes with a stare that instantly elevated my heart rate, she lifted the tank top over her head and tossed it to the nearby chair. Working deliberately, she unbuttoned her shorts and pushed them slowly down her shapely legs; when they hit the floor, she playfully kicked them over to the chair. Standing in just her bra and panties, she turned around and faced away from me as she reached behind her back and unfastened her bra. Just fifteen minutes earlier, I had masturbated in an attempt to take the edge off; we hadn't even started yet and I was already uncomfortably hard. While her back was still turned away from me I adjusted myself.

Ashley turned her head, "I saw that. Is that what I do to you?" she asked as she turned to face me.

My heart skipped a beat. "God, Ashley; you are so fucking beautiful."

Ashely blushed and looked away momentarily. "Panties too?" she asked, reflexively touching herself as she spoke.

I thought for a moment then replied, "Not yet." I wanted to leave something to my imagination!

"Where do you want me?" she asked.

"Over there," I said, pointing to the window. "When was the last time you touched yourself?"

"The last time we were together," she replied.

"Do you think you deserve an orgasm today?"

Ashley turned and faced me, a dark, lustful look on her face. "Yes."

After seeing how much she "enjoyed" the use of clothes pins on her nipples the other day, I got an idea in the middle of the night. I reached over to the nightstand and grabbed the bag of clothes pins. I counted out ten of them and placed them on the desk near where she was standing. Ashley looked over at the pile of clothes pins and swallowed.

"I want to you to take those clothes pins and clip them to your body - two on each breast, two on your belly, and two on each of your butt cheeks. Ashley shifted her feet as she looked at me, and then the clothes pins.

"Did you think I was just going to spank you a few times and let you touch yourself?"

She shook her head.

"This is what you've wanted all along, isn't it. You wanted someone to fulfill your fantasies of being dominated, forced to do things as penance for your sins."

She sighed then whispered, "Yes, Michael...I'm glad it's you."

She took the first pin, played with her nipple to get it hard, then gingerly placed it square on her nipple. She drew in a shallow breath as she released the pin, allowing it to fully clamp down on her nipple. She repeated the process with her other tit, then went back and placed the second close pin in place. She breathed in and out as if she were in labor.
