Playing Light Tag with Sis

This story is pure fiction and the product of my own imagination. All the characters are over eighteen. I look forward to any constructive critiques and would appreciate it if you would please vote. Cheers!

Donnie and Pia were eighteen year old twins. Pia was the oldest, by fifteen minutes, and the two were practically inseparable. They were so close their friends would sometimes joke, behind their backs, that the two were probably holding hands when they were still in the womb. The two teens, though popular, were relatively inexperienced when it came to sex.

"Did you know that when I'm sitting on my bed I can look right into your room?"

"Gee, lucky you! How exciting!"

"Well, actually sometimes it is. Why don't you ever shut your door?"

"If you must know, I don't shut it because the dog likes to come up and sleep in my room at night. If I shut my door he whines and scratches at the door. Besides, what's it to you anyway...why do you even care?"

"Oh, I don't care at all. It's just that you probably ought to know that every night, and I mean EVERY night, I watch you jerking off in bed. Just thought you might like to know, that's all."

To say I was shocked would be an understatement! I was mortified, but I tried to keep a straight face. "So why don't you close your door if it bothers you so much?"

"Why should I? I'm not the one doing it."

"Why should I believe you? It's dark in my room. How can you see anything?" I countered.

Pia handed me her phone. Sure enough, there was a video of me stroking away. Apparently there was sufficient light filtering in from the outside street lamp to provide just enough light in my room.

"HOLY CRAP!!!" I yelled. "Have you showed this to anybody?!?"

"No, I wouldn't do that to you. These videos are just for me."

"VIDEOS!!! WHAT DO YOU MEAN VIDEOS?!? How many of "these videos" do you have?" I implored.

Pia looked me straight in the eye. "Lots. I don't know how many. I can't believe you've never seen me watching and recording you."

"So what've you been doing with these videos?"

"Nothing, just watching them on my own. That's all."

"I can't believe you haven't shared them with your friends!"

"I told you, these are just for me. No one else."

"So why are you telling me all of this? What do you want?"

"Well, truth be told, I really get off watching you. It makes me horny. Sooo, I'd like you to please turn on this little night light when you're playing with yourself." She explained as she handed me a small plug-in night light.

"Why should I do that!?!" I implored.

"I told you. I like watching and this way I'll be able to see better, that's all. Look, I've got one of these things for my room too. I'll let you watch me too. You can record me too if you want...call it insurance, I don't care. Come on, it will be fun!" Pia said.

"I don't know. I don't understand. If you want to watch, if you want to get a better look, why don't you just come into my room, or invite me into yours?" I asked.

"Yeah, I thought about that, and yeah, we should do that too. I'd really like that, but if Mom or Dad ever caught us...I don't even want to think about it..." Pia said.

"Are you expecting me to turn this on every time I jack-off?"

"That would be great! But no, just use it when you want, that's all. I mean I can see in your room anyway, it's just if the light is on, I'll know you're in the mood to play. Look, I'll turn on my light tonight, just so you can see what I'm talking about."

"I'll think about it." I said.

"Okay, that's fine. Look, I know I'm being weird. My getting off watching you get off is freaky, kinky and sicko, I get it. If you're not into any of this that's cool. Just rearrange your bed in your room and that will be the end of it." Pia explained.

"Look, I don't care if you want to watch me. I'd kinda like to watch you too. It's just that those videos kind of freaked me out, but if you tell me they're strictly private, then I believe you. I guess I'm just not getting my head around the idea of my sister being my jack-off buddy."

"Jack-off buddy? Would you want me to jerk you off?"

"Well, I wasn't actually thinking that, I thought we'd just be watching each other, that's all. But yeah, I guess. If you want to, sure, why not? Maybe sometime I could get you off too." I said.

"Mmmm, yeah that might be fun...real fun." Pia mused.

Later that night when I went to bed I just tossed and turned. I kept all my lights off and tried to sleep, but it was impossible. Every time I opened my eyes I found myself peaking at Pia's room. Nothing. I was beginning to wonder if she was pulling some bizarre practical joke.

POP! Light On! In the dark house, that little night light really illuminated Pia's room. She was sitting up in bed unbuttoning her pajama top. As it slipped off her shoulders she revealed her breasts. "WOW!" I thought."She is HOT!"

I'd seen my sister in bathing suits and skimpy clothes before, but she was my sister. I just seemed to discount her and didn't really pay that much attention.

I was sure paying attention now! Pia was drop dead gorgeous. Her breasts weren't particularly huge. I didn't know that much cup size, but they looked to me to be somewhere between a B and C-cup. They looked perky and firm. Her pinkish-brown nipples were puffy and swollen. The sight of her long light brown hair cascading down over her flawless alabaster skin was breathtaking. She laid back and lifted her hips while she pulled down her pajama bottoms. After kicking them off she spread her legs and began slowly fingering herself. As I watched her slide her fingers up and down, back and forth over that glistening slit I got harder and harder.

I didn't bother with the night light, I got out of bed and flipped on my bedroom light. I stood silhouetted in my doorway busily pumping my cock while I watched Pia finger herself. She stared back at me with a serious, determined look on her face. We were both consumed in our shared lust.

Suddenly, I heard Pia give out a sharp little yelp as she drew up her knees. At the same moment I shot my cum straight out into the hallway. Globs of it landed all over the hardwood floor. I pulled off my tee shirt, dropped it on the floor and moved it around with my foot, wiping up my mess. When I glanced up, Pia gave me a little wave and then turned off her light.

The next morning Pia asked, "Sleep okay last night?"

"It took me a while to fall asleep, but yeah, it was incredible! Can't wait to sleep like that again!" I answered.

"Me too." Pia said. "I really liked watching you cum, it made me so hot. Just thinking about it made me frig myself again after we turned out the lights."

"Are you kidding? I had no idea! So, are we on for tonight?"

"Of course!" Pia eagerly replied.

We continued with our little routine for a couple of weeks. I'd started my own little collection of videos I had taken of my sister and jacked off to them often. Then one night Pia turned on her night light, but instead of doing her seductive striptease routine, she waved me over into her room.

As soon as I got in there, she whispered, "Can I jack you off?"

I nodded and slipped off my boxers. I was already hard. In hushed tones I said, "Take off your top! Let me play with your tits while you jerk me off."

Pia pulled off her top and readjusted herself so she was leaning with her back against the wall. I was lying on my back with my head in Pia's lap. I was lost in my own world as I massaged, kissed and sucked on her perky tits. Pia was pumping and rubbing my cock like a true master. I didn't need any lubricant because all the precum I was leaking out was keeping me well oiled. It didn't take long before I started bucking and cumming, Pia covered my mouth with her other hand to try and stifle all my groaning. She bend her head down so that we were literally nose-to-nose and in a very low, yet determined voice said, "DONNIE, SHUT THE FUCK UP! BE QUIET!"

As soon as I came she kicked me out of her room.

"What about this mess I've made?" I whispered while motioning to her cum sprayed bedding.

"I'll take care of it! Just go back to your room and BE QUIET!" She insisted.

The next day when we were alone Pia really let into me. "You stupid jerk! You almost got us caught! Why did you have to be so loud?"

"What are you talking about? I was quiet!"

"Bullshit! I wouldn't be surprised if Mom and Dad think I had a boy in my room!"

"Well, you did!" I said.

If looks could kill, I would be dead. "Look, you and I have a good thing going. Don't ruin this by being stupid." Pia lectured.

"Okay, you're right." I said. "Look, maybe we should cool it for a while. I'll tell you what, next time I promise I'll make it up to you." I said.

"Okay, good idea."

The following Saturday Mom and Dad were out playing golf. This was pretty much a weekly routine with them. They would play golf all day and then go out to dinner afterwards. They usually did not return home until later in the evening. Knowing we had the house to ourselves, we decided to make the best of it.

"Well, we have all day, what do you suggest we do?" Pia asked.

"We could wash the windows and vacuum the carpets. I know Mom would really appreciate that." I mused.

"Yeah, we could...but other than just vacuuming, maybe there's something else we could do on the carpet." Pia countered.

"Hmm, there's a thought, but it's such a gorgeous day, why not go outside. The lawn in the backyard looks inviting."

"Oh, I REALLY like the way you're thinking!" Pia gushed. "I've fantasized about getting off in the middle of the living room floor, with the curtains to that big bay window wide open, but outside seems pretty hot too."

"Why can't we do both? I can get you off here in the living room and then you can do me in the garden...next time we can switch it around!" I said.

"I love you little brother, I really do!" Pia said as she gave me a big hug.

We both stripped out of whatever we had on, and Pia went over and open the curtains to the big bay window. We were both fully visible to anyone who cared to look in.

I was embarrassed. "I've never actually done this before. How do you want me to do this?" I asked.

"I don't know, just play with my pussy, but don't be too rough...be gentle. Just finger me, you'll figure it out by my reactions. I'll let you know."

I pretty much forgot about the open window and any passerby's and focused on Pia's pussy. She had a nicely trimmed patch of brown pubic hair. Nestled below it was her slick, wet slit. I gingerly slid my fingers into it, gradually spreading open her moist lips. I tried to mimic how I'd seen her do it. The heady scent of her sex filled the room. My cock began to grow and grow. Precum was already beginning to leak out and drip onto the rug.

I inadvertently slid my finger over Pia's clit. She instantly drew her knees together, threw her head back and uttered a little cry. I felt as though I literally had the control of my sister in the palm of my hand. I alternated between fingering her vagina and that hard little button. It seemed each offered it's own special response. I sped things up and slowed things down. I inserted my finger up inside her and caressed the lips of her labia. I tried everything I could think of to mix it up, just to gauge her reactions, but I kept coming back to her clitoris. Without fail I got her strongest response from that little hard, pink, nub.

Finally, I concentrated on that one little spot. Pia went into orgasmic convulsions. As she writhed and bucked her moans evolved into screams, "hmmmmm, mmmmm, yeah, hmmmm, mmmmmm, yes, yes, yes, AGHHH, AHHHHH, YES! YES! YES! YEEESSSSS!!! OH GOD YES!!!!"

I couldn't hold back either. I jumped up onto my knees and uncontrollably came all over my sis. I shot rope after long gooey rope of cum all over her hair, face, chest and tummy. Pia instantly started smearing my sticky cum all over her body. She was physically spent but had the most satisfied smile on he face.

"Well, so much for the garden." I murmured.

"We just need to recharge our batteries. We'll get out there later. Believe me, we will. Besides, I owe you...a big one!"

"You owe me?"

"Yeah! What do you think? I just had THE MOST incredible orgasm, and you gave it to me. I want to...no, I need to, return the favor."

Pia and I laid there on the carpet holding each other. When we got up our skin was stuck together. We laughed as we peeled ourselves apart.

"Do you want to take a shower with me?" I asked.

"Yes, I'd love that, but not now. I want to walk around naked, smeared in your cum."

"Hmm, kinky...I like that!" I said.

Later that day Pia took me by the hand and led me out into the backyard. She invited me to lay down on the lawn. I was laying on my back in the bright sunshine. Pia knelt beside me lightly stroking my dick. Suddenly, without any idea it was coming, Pia leaned over and kissed the head of my cock. Then, slowly and deliberately, she swallowed it down, engulfing my entire length. Never, in my life, had I ever felt anything so incredible. I laid there taking it all in. I watched Pia's breasts swaying back and forth as her head bobbed up and down. I was pumping my pelvis, driving my cock to meet my sister's mouth. The constant slurping sound, combined with the all too often choking and gagging filled the backyard with the sounds of sex. She thought she was prepared, but when I finally came, it was much more than she ever expected. Pia later said it felt like someone had let loose with a firehose. My ejaculate first flew straight into the back of her throat, causing her to uncontrollably choke and gag. Pia immediately pulled off me, but as she did, the next rope of cum went up her nose and directly in her eyes.

She knelt there on her hands and knees gasping for air as I continued to ejaculate all over the both of us. She was flushed, with tears running down her cheeks. She definitely looked spent, and I assumed we were done, but as soon as she composed herself, she bent forward and sucked my cock back into her mouth. She sucked on my near limp dick and then licked up the residual cum off my groin.

For the second time that day we had to recover from a torrid sexual encounter.

"I love being out here naked, it feels so good!" Pia observed,

"Yeah, this is great. I wish we could be like this all the time. But tell me, what was it like sucking my dick? How did you like it?" I asked.

"It was all right. Actually, it was great! And sort of fun! I liked how turned on you got. But I wasn't prepared for all that cum! Jesus Donnie! I thought I was drowning there for a second! Next time you'll have to give a girl some warning!"

"You mean there'll be a next time? You were choking so much I wasn't sure you'd ever want to do it again." I asked.

"You know what they say..."practice makes perfect" and I need a lot more practice."

"So I guess now it's my turn to do you."

Pia just looked at me and smiled.

Afterwards we showered, dressed and ate dinner. We were watching television when Mom and Dad came home.

Later that week while we were playing light tag, Pia scurried over into my room.

"Donnie, I've been driving myself crazy thinking about you going down on me. I can't wait until Mom and Dad's golf day. Will you do me now,/ tonight, PLEASE?" She implored.

"Sure!" I said as I got up and closed my bedroom door.

Pia laid back on her elbows, her legs spread wide as they dangled down to the floor. I knelt between her legs and lowered my face as I stuck out my tongue. I tentatively explored every wrinkle and fold of Pia's labia. Pia lifted her feet up and rested them on my shoulders. She pressed her feet hard into my muscles as she leveraged her pelvis up into the air. Just as I'd experienced before, that rich overpowering aroma of her sex just spurned me on. Then I stuck my tongue as far in her as I could and I tried as hard as I could to fuck my sister with my mouth. Then I licked and sucked on her hard, pink, little nub of a clit.

"Mmmmmm aaaaaah mmmmmm yes yes yes yes yes aaaaaah" she softly murmured over and over again like a mantra. Then, abruptly, she sucked in a deep breath of air while clamping her thighs tightly around my head. She twisted and bucked like an untamed bronco. I briefly worried about whether she was going to either suffocate me or snap my neck! Finally she dropped her legs and went totally limp.

Pia leaned forward, held my face in her hands and gave me a deep, wet, tongue swallowing kiss.

"Donnie, you never cease to amaze me! That was incredible!" She whispered as she stood up and headed back to her own room.

Over time we gradually became a bit bolder and began pushing the limits of our sex play...even when our parents were around.

The thrill of being caught effected us like a drug. While watching television we liked to sit together on the couch with a blanket spread over our laps. Our fingers would gradually inch over to the each other's lap. Pia, in particular, really got a thrill out of jerking me off with our parents in the room. She would get this funny grin on her face when she knew I was about to cum, but trying like hell not to alert the world.

One evening while Pia and I were just hanging out she said to me, "Can you keep a secret?"

"I think I've done pretty well keeping our secrets so far, what's going on?"

"I'm on the pill."

"WHAT!?!" I asked in disbelief.

"Yeah, I am. The other day when I had my annual physical I asked my doctor about it, and she went ahead a prescribed it for me."

"So does this mean...?"

"Yep." She replied with a nod and a smile, "...it sure does. The next time Mom and Dad have one of their golf days, we can have our own special day."

Sure enough, the next Saturday our parents took off to play golf. Pia and I were eager to begin this new phase of our relationship, but I could tell that Pia was a little apprehensive.

"You know, we really don't have to do this if you're not ready. If you want to wait until you're more comfortable with all of this, or until you meet the right guy, I totally understand." I said.

"Donnie, YOU are the right guy. There could never be anyone, anywhere, who I'd rather do this with. We've had ALL our first times together. There's no one I'd rather be with. I'm just not sure how much it might hurt or how I'll feel afterwards." Pia explained.

"Well, I say again, we can wait. I'm totally cool with that."

"Thanks, I really appreciate that, but I want to do this today...now."

Since we lucked out with another gorgeous day, we decided to do this in our favorite spot in the backyard. We both applied lots of lubricant. Pia thought she would feel more comfortable being on top thinking she would have better control.

We got into position, and without any ceremony, Pia tentatively lowered herself onto my hard cock. She asked me to be still as she gradually settled in. The feel of her warm, wet vagina swallowing me up was truly one of the most memorable moments in both our lives.

"Are you okay?" I whispered.

Looking concerned Pia responded with a husky voice, "Yeah."

She eventually settled in. My entire cock was buried deep inside my big sister. Slowly and warily Pia began rocking her hips. As she became more comfortable she increase the pace. Pia closed her eyes and undulated her hips back and forth and from side to side. I could see on her face she was in heaven.

Pia looked up, immediately crossed her arms over her chest and froze. I turned my head to see what she was staring at, and there, looking at us through the sliding glass door were Mom and Dad.

Dad opened the door and Mom motioned us in. As soon as we got inside, Mom and Dad hugged us both. Pia and I were shocked to see that our parents were naked too.

"We are so happy and proud of you both!" They both proclaimed.
