I broke both of my thumbs in a car accident, on my 19th birthday no less, The investigating cop said if I'd had my hands at 10 & 2 like they taught in Driver's Ed, the airbag would have pushed them up and away from the steering wheel. Since I like to drive with them at 5 & 7, the exploding airbag stopped the momentum of everything except my hands. So here I was with plaster up both arms to mid-level and thumbs locked outward.

At least I had the use of my fingers as the casts stopped at knuckle level, but it is almost impossible to pick stuff up this way. And wiping my butt was barely possible if I held the tissue between 2 fingers. Usually I just hopped in the shower and rinsed my buns off in the stream. Anyway, the worst of all my issues was that I was finding it literally impossible to masturbate with just use of finger tips I tried putting the Vaseline jar between my mattress and box springs but then cum dribbled all over the carpet. I got no relief humping my pillows. So, after a whole week I was going insane.

My 14 year-old sister, Lynn, was helping me make a bowl of cereal one morning and noticed my huge erection pushing out the front of my pajama bottoms, which by then was a pretty constant event. She has long blond hair down almost to her waist and a great looking butt right below it. She's skinny but not emaciated and carries a nice set of 34 C tits that seemed to have grown a bit this year.

She made a joke about my 'problem' which opened the topic to discussion.

I blushed but then honestly told her that I hadn't been able to jack off for a week and that I had never previously gone more than a day without an orgasm. I explained how I was finding it difficult to think about anything else. I was cumming in my sleep and messing the sheets at least once every night. Mom was wondering why I took a sudden interest in doing chores around the hous, especially doing the laundry.

Then I got bold and asked her for help. Please, just a quick hand job in the bathroom and I'd do anything for her once I was able. At first she refused, but later that day she noticed the tent pole sticking straight out again and shyly asked if I really wanted some help with it.

"Really?" I asked. "You'd be willing to help me?"

"I was thinking about doing it for you. In fact, it's crazy but thinking about it made me wet. I like to rub myself off at night to get to sleep. If I couldn't feel that little wave of pleasure I'd probably go crazy too," she said. "Here's a little secret since we're being so truthful with each other. I discovered my little slit and nubby when I was 6 but since I hit puberty and grew my muff hair, the climaxes are so much more intense."

"So, yeah, I'll help you out with your dilemma," she said. "You just have to show me the right way. I've never done it before," she admitted, somewhat shyly.

"Plus I have almost no experience. I've only seen a few photos of guys shooting out a load. Patty, my bff's father had a movie that she found in his sock drawer and showed at one of our sleep overs. It had a bunch of guys jerking themselves off on the beach. One friend called it a 'circle jerk'. When they climaxed, there was not much to see since the camera was a ways off. But their legs started to shake and they got happy expressions on their faces. We giggled at the sight anyway.

"I enjoy teen slumber parties way more now that I did when I was younger. Once the lights go out, we all get busy in our jammies and soon most of us are moaning. Once at Gloria's, we even left the lights on. You should sneak over sometime to watch a bunch of girls masturbate; it's really fun in a group when we know no one is going to blab later at school.

"I shave a little bit on the sides for my bikini but several of the girls in our group have bald twats. I don't see the benefit. I like to rub in my curly hair with one hand as I circle my little clit with the other."

"So I know how to do me," she continued, "But on you I don't know where to rub or stroke, how hard to pull or what tempo to use."

"Oh sis, that won't be a problem at all," I said as we went into the bathroom and I pulled down the front of my pants and released my erect cock and balls. Just thinking about my sis giving me that sweet relief made my pole quiver and jump with anticipation.

"Wow, you have a huge one," she giggled. "Look at it jump. Ok, so what do I do first?"

"Well, squirt some lotion in your hand and then rub it on my penis." I told her, nervously. I was so eager to cum that I used the medical term since I didn't want to chance scaring her off by calling it something crude. I sat down on the toilet while she applied a dollop of lotion to her right palm.

"Ok, hold my penis at the base with your left hand and rub the lotion on the shaft like you're applying it to your wrist or something."

She approached me and gently put her left hand around the base and started applying the lotion to the shaft. "Ok, now move your hand slowly up over the head," I told her.

Her touch was almost imperceptibly light as she carefully and slowly moved her hand up the shaft and then over the tip. "Squeeze the base a little harder and just spread the lotion around," I instructed. She gripped it more confidently and twisted her hand around to get my cock covered completely in lubricating lotion. "OK, now just stroke it up and down over the part right there where the shaft and head come together."

She began to stroke, clumsily at first, but I guided her with some well timed ass thrusts and talked her through it.

Once she caught her stride, I could feel my orgasm approaching. The tingle was much more intense than when I jerked myself off and her clumsy inconsistency seemed to repeatedly bring me to the edge and then just as suddenly take me back down. I watched her staring at my cock intently as the head would disappear into her clenched fist with each upward stroke, then burst back through on the downward stroke. She had this dreamy look on her face and a slight smile. I realized she was enjoying the sight of my throbbing cock and the squishy sound of the lotion as she jerked up and down over and over. Then her tongue came out a bit between smiling lips.

That was all it took and in just a few seconds I could feel the jizz gathering and I groaned, "Here it comes! I'm cumming!"

She continued to stroke as what felt like the strongest orgasm I'd ever had ripped through my balls and a geyser of semen shot into the air, coming straight back down to coat both my cock and her hand.

"Whoa!" she chirped and jerked, pointing my prick toward my front and away from herself. Another gush of cum shot out, this time landing on my chest and stomach, followed by a much longer third eruption that just rolled down my shaft to puddle in my pubic hair. I moaned again and slumped back onto the toilet.

"Oh, blessed relief," I cried!

"Stroke it really lightly a few times until the sperm stops coming out," I finally panted. Very daintily she squeezed and pulled a few more times as a bit more semen dribbled from the tip.

"Are you all done cumming?" she asked me, still gripping my cock.

"Yeah, I'm just kind of recovering," I told her with my body trembling. "That was the best orgasm I've ever had."

She looked surprised and then smiled proudly at her accomplishment. "I didn't know so much stuff would come out!" she exclaimed.

She grabbed a wad of tissue to clean me off, taking special care to clean up my pubic hair which necessitated her continued handling of my still gently spasiiming cock. She glanced up at me as she ran her finger on the top of the head to grab the final drop of cum and then licked her finger! Wow, was I surprised.

"Tastes a little funky and weird but not bad, not bad at all," she smiled as she smacked her lips.

Now that the dam had broken, I knew all I wanted was more of her sweet stroking hand. As if my dick had a mind of its own, it began to stiffen. She looked at it grow in her hand and began to squeeze gently and stroke slightly.

"Again?" she asked, licking her lips.

Soon I was at full mast and throbbing, planning on a second load to ease my tension. But just then we heard the garage door go up and I had to scramble back down stairs to plop in front of the TV as mom came in the garage door. Lynn dashed into her bathroom to wash her cummy and gooey hands.

"Hey, kids," mom called, "Come help me with the groceries." She looked at me sitting uncomfortably with my legs clamped tightly together to keep my boner from sticking out. "What is up with you?" she asked. "You look like you are in pain. Are your thumbs bothering you right now?"

"Not much mom," I replied. "I'll be right out to help you." Thankfully, she turned to go back into the garage so I could adjust my throbbing dick in my pants and finally stand up without her noticing my raging hard on.

After dinner was over and we'd cleaned up, mom and dad settled in the front room to watch TV, I got Lynn alone in the kitchen and whispered, "Would you want to help me with that thing again?"

Her face lit up and she nodded her head with a smile. Then she reached down and pressed gently on her crotch through her short shorts. I couldn't believe my own sister was a horny little cunt, getting excited at the mere thought of jerking me off again.

"Go to your bedroom and wait for me," I instructed.

She disappeared and I messed around in the kitchen for a few minutes, then followed her, past the TV room and up the stairs.

"I guess I'll get to some homework in my room", I mentioned as I passed by them. No worry, they were glued to the show on TV. I banged the door to my room closed to make sure they heard it and then quietly went into hers, gently closing the door behind me. She was sitting on her bed with a bottle of lotion and a box of tissue all ready.

"Lie down on my bed," she instructed.

I lay down and she unzipped my pants and pulled them down to my thighs. As if an expert now, she applied the lotion to her hand and then positioned her other hand at the base, covering my balls. Next she took my erect cock into her lotion covered hand and started to stroke, requiring no instruction this time.

I suddenly noticed that she had changed into a tight shirt with no bra, and a very short skirt. She had let her hair down and was wearing some light makeup. She certainly didn't look like this at dinner. I could see the form of her perky breasts through her shirt with her nipples plainly visible. As she began the slow stroke up and down I could see her nipples clearly stiffen and poke through the shirt material. Was she enjoying this more than I had thought she would? I was almost in heaven, knowing my little sis was getting excited as she jerked my dick.

As I lay there with her hand pumping up and down, I day-dreamed about her sweet pussy lurking just under the bottom of her short skirt, snug in some tight cotton underwear, and clearly getting wet. Maybe her cunt was also clenching with anticipation. Whoa! That was all it took as suddenly ropey jets shot into the air with each wave of my orgasm. "Oh, I am cumming," I moaned too late. I looked up at her to see a satisfied and confident grin on her face.
