Too MuchTeasing

By the time I was fourteen I was already quite muscular from sports and the changes of puberty. During the Xmas break in high school, I was finally catching up on my sleep. I also began to awaken every day with an immense hard-on. I had heard about jerking off from the older boys on my sports teams. I experimented and learned the pleasures of touching myself. 

My older sister noticed that I was becoming quite grown up too. How could she not; I was already four inches taller than her even though she was two years older than me. Her reaction was to tease me. Whenever our parents weren't around, Marie would stroll through the house with almost nothing on. Not only was I being tantalized by her near nudity, but she was also making suggestive remarks. 
"Stevy, what's a four letter work for intercourse?" she would ask and watch my face flush and listen to me stutter. She was pretending to work some kind of puzzle. After enjoying my confusion for a minute or two, Marie would suddenly blurt out, "Oh, yeah... TALK," and then pretend to write the word on the puzzle sheet. 

After a couple of days, my cock would spring up at the sight of my sister, usually clad in flimsy panties and her smallest, least opaque bra, nonchalantly strolling by me again and again. I could not even take shelter in my own room. Marie would find some reason to burst in on me and get me stirred up. 
"Stevy, do you ave a big, hard pencil I could borrow?" 
"Stevy, does this bathing suit look ok?" 
"Stevy, do these panties go with this bra?" 
Marie would soon leave, and I would head for the bathroom to jerk off with the hand cream from the closet. Even there I could not be at peace. Unable to unlock the door, she would tap and scratch, like a cat in heat. "Stevy, I need to get in there. Will you be long?" 

She must, I thought, want to have sex with me. How could we do that? Marie was my sister. I knew that it was wrong; it was incest. What could I do? I was shy and had never been on a real date. Marie was giving me aching hard-ons and a vision of herself that I would hold in my mind when I was pounding my meat. 

I went to take a shower one morning and was distracted; I forgot to lock the bathroom door. I hung up my robe and got under the warm spray. In a few minutes a heard a slight noise. Suddenly, the shower curtain was pulled partly aside and my sister was right there, clad in only her panties. 
"Do you mind if I use the sink while you shower?" she asked as if it was the most normal thing in the world for us to be naked together in the bathroom. 
"MARIE!" I cried out, trying to cover my cock with my hands. 
"Thanks, Stevy," she answered and let the curtain fall back. 
I was as hard as a steel pipe. I peeked out and saw her washing her little titties with her wet hands. She knew that I was looking and turned toward me with a big grin. 

It was too much. I pulled the curtain aside and dragged Marie into the shower with me. I was surprised that she resisted so much. 
"You're getting my hair all wet, asshole," she cried. 
"Who cares, you slut," I replied. I pulled her close to me under the spray and ripped her panties off. They were so flimsy that they almost melted away under the spray. I ran my hands all over her wet, silky skin, feeling her boobs, grasping the soft roundness of her hips, and gripping her firm butt. 
"I'm going to tell!" she threatened. 
"Who cares," I answered again. "You've been teasing me all along; now you are going to get it." 
"No, Stevy, please; I was just joking... only playing." Her pretty face screwed up, and she began to cry. 
"I'm not playing any more of your little games, Marie. You know what you have been doing to me. Look! Go ahead; look at my cock." I grabbed her head and made her look down at my crotch. 
"Oh god," Marie moaned. "It's... it's... " 
"It's my penis, Marie, and you made it so hard that it aches. What are you going to do about that?" 

"I... I.... d-don't... know," she blubbered. "Please don't hurt me." 
"You can begin by..." Did I dare, I thought, "yes... by giving me a hand job. You can relieve my hard dick." I had heard the older guys say that they got hand jobs from their girl friends. 
"What's that?" Marie asked, calming down and becoming curious. I could see her eyes roaming over my naked body almost as much as I was appreciating her nudity. 
I took her hands and put them around my prick. "Pump up and down and you'll get a nice surprise," I said. She began to stroke me, and it felt amazingly good. She mostly looked at her hands working on my cock, but now and then she would look up at my face. Marie was jerking me off slowly and steadily. It was almost torture, but I loved it. I began to moan, and, when I opened my eyes, my sister was staring at my face with a look of surprise. 
"Does this feel good?" she asked. 
"Oh, yes, it's so good," I mumbled. "Don't stop!" 

Her mouth opened with a little smile, as if she was realizing the power her little hands had over me. I groaned loudly, and the first gobs of my cum gushed out of my throbbing cock and splattered on Marie's bare skin. 
"Oh! Wow!" she screamed and pumped faster. More of my milky semen flowed out, dribbling onto her hands. My sister continued to milk my cock until the last drops fell away. She let go of me and embraced me, pressing her wet, naked skin against mine. Recovering from my sexy, incestuous ejaculation, I began to stroke her body. 

"Was that good?" my sister whispered into my chest. 
"It felt really good. Do you want me to feel you up a little?" Now, I really had no idea what feeling up a girl involved. I sensed Marie nod her head yes, so I knew that I would have to figure it out. I slid a hand between her legs, but I was uncomfortable bending over. I got down on my knees. I pressed my face into her soft stomach and kissed the wet flesh. 
My sister slid her feet farther apart, allowing my hand better access to her pussy. Looking down, I could see the dark fur that began under her belly. 
"Put a finger inside me," Marie begged. I pushed my middle finger deep into her vagina and began to stroke the soft membranes. I wanted to see her pussy; I sat on the shower floor and pulled her hips to me. Her cunt looked so nice that I began to kiss it while I fingered her. I could feel her rocking her hips against my face. 

Marie reached down and grabbed my head with both hands and pressed my face more firmly against her twat. Now, instead of just kissing her pussy, I began to lick her and slide my tongue up and down the crevice between her outer lips. 
"Just like that... don't stop... please don't stop," she moaned. I felt a spot inside her pussy and rubbed it with my finger. Marie suddenly screamed and a flood of tangy juice spurted from her cunt. She had come, just like me, and had splattered me with her juices. I swallowed some of her emissions and realized that my cock was again swollen with lust. 
As I sat there pressing her pussy against my face, I noticed that my sister had become very rigid. Soon she relaxed and I continued my illicit embrace. 

"That... that was SO good!" Marie exclaimed after a few minutes. "I have never felt anything like that before. No wonder you moaned when I milked your semen out." 
I slowly got up and turned off the shower. Marie looked down and saw that my cock was hard again. "Spread you legs apart again," I said. "I want to try something." Marie did as I asked, and I bent my legs as I closed in on her. The head of my hard prick was just under her delightful crevice. I held my cock in my hand and rubbed the end up and down her slit. 
"That feels good, Stevy." 
I started to press my cock more deeply between her labia. Marie put her hands on my shoulders to brace herself. I pushed deeper to the place where I had pushed my finger up inside her. The entire crown of my prick was between her outer lips. Marie sighed. I pushed upwards and another inch of my cock was inside my sister. 
"Owww," she moaned. "That hurts. Stop for a minute." 

While I waited, I kissed her nipples and then sucked on them. At last I could not help myself; I pushed up again, and another inch of my cock disappeared into Marie. 
"Ouch... Oooo... maybe we shouldn't do this any more. It doesn't feel good." She now looked worried. "I don't want to get pregnant. mom and dad will KILL us." 
"Just a little more," I murmured. "Then we'll stop. I'm not ready to come again yet, so I think it's all right." 
"Ok," Marie said after thinking for a moment. "Maybe we can try again some other time if it keeps hurting." 
I nodded in agreement and bucked my hips again. My cock slid almost all the way into my sister's tight cunt. She didn't say anything, and her face showed no further sign of pain. I pushed again, and I was all the way inside my sister, buried in her fertile womb. 
"I feel stuffed," she whispered. "You feel good in me." 
"Yeah," I murmured and began to move hy cock in an out. We were really doing it... fucking, but we could never tell anyone. My sister hugged me to her and sighed with contentment. I felt myself beginning to roil up deep in my groin. Remembering Marie's words, I knew I had to pull out of her soon, or we would be in trouble. 

I pulled myself out; I had to force myself to do it. I wanted to go on and on until I spilled my sperm deep in her pussy. "You need to help me again," I told her. "Use your mouth this time." I had heard about blow jobs from the older guys too. They all claimed that their girl friends sucked them off as a special treat. 
Marie knelt in front of me and tentatively put the head of my cock between her lips while she stroked the shaft with one hand. She looked up at me. 
"Deeper," I said, "and suck me too." I watched as my sister slid inches of my cock into her mouth. I could feel her tongue swabbing the sensitive head. I could feel the suction of her lips. When I looked down at her pretty face, my cock was in her mouth, and her soft cheeks were indented by the suction. 

It did not take long. I began to fuck her face in the urgency of my need, and Marie began to move her head in time with my thrusts. I groaned with pleasure and jetted my semen into her mouth. Marie let it drool from her lips and drip off her chin. She gamely sucked me until the last drop of semen was out of me. 
"I guess we need another shower now," Marie said with a smile. 

We learned a lot about sex that vacation. We found some books that our parents had hidden away, so we learned how to play it safe. I never came inside Marie those first years; she always used her hand or mouth to finish me off. Marie, on the other hand, did have climaxes with my dick buried in her tight cunt. When we were older we used condums and then Marie was able to get birth control pills. We are still lovers, so perfectly attuned to each other's needs, that, even ten years later, we want no one else.
