By the time I was Nineteen I was already quite muscular from sports and the changes of puberty. During the Xmas break in College, 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 have 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.
