Gemma

Growing up wasn't easy with an older sister. GEMMA was 2 years older then I am and loved to torment me. Pretty typical I guess. I was the nerdy little brother. Where Gemma was blessed with the superior looks in the family, I was blessed with the intellect. Not that she was stupid, things came harder for her and she didn't have the self-discipline to study harder.

Gemma was also the popular one. Typical cheerleader type at our school, which also meant she could be a bitch at times. She was outgoing and liked to be the center of attention. I was quieter and more socially awkward. Gemma especially delighted in that at times I could be easily embarrassed.

At school, we had little interaction. It was at home where she tended to set me up for her own personal amusement. She loved to make me blush. Every once in a while though, I would catch a glimpse of her that told me she wasn't quite the bad girl she liked to portray, by things she would do or say.

She had gotten herself into trouble with our parents on more than one occasion, usually in connection with her friends. Truth be told, Gemma was a follower, not a leader.

By the time I was 13 a favorite game Gemma loved to play was to get me aroused and flustered. She would prance around me in a T-shirt and panties, or a skimpy nightie, or a towel, and do things to get me sexually excited, then lower the hammer on me by making a fuss about it. She'd tell me what a pervert I was and threaten to bust me out to our parents.

She'd get a good laugh out of it when I'd blush furiously, and stammer about, trying to deny any improper thoughts. Problem was, often my thoughts were on the improper side. This made the feeling of guilt in me all the more stronger. More than once she conned me into doing her chores by telling me that it would keep her from spilling the beans. Of course, if I hadn't felt guilty about what I was feeling, her tactic wouldn't have been nearly as effective.

More than once I was lured into the bathroom or Gemma bedroom only to fall prey to one of her traps. I learned to become very wary around her. I'd be lying though if I said I never masturbated to images of my sister. She'd call me in for one reason or another and when I'd enter I'd catch the briefest glimpse of her half dressed which would illicit a shriek from her. More than once she came into my room while I was working at my computer, wearing something skimpy and sexy. She'd stand behind me and press her breasts against me, brush her hand against my skin. I'd feel her warm breath against my neck and just like that, the trap was sprung.

Still, there were a couple of occasions when I actually got a view of a breast, or ass cheek. Never a very long or very good look. I got the feeling when that happened that she was taking pity on me. What I didn't know and wouldn't find out until later was that aside from tormenting me, Gemma got a bit of a thrill from being naughty in front of me and from the effect it had on me.

The damn fact was that Gemma was very sexy. She had such a tight, hard body, nice sized boobs, and an ass that was criminal. She was toned, athletic, and tanned. She had long brown hair that went below her waist, almost to her ass and was silky and soft. One of my punishments sometimes was to brush it out for her. In actuality, I liked brushing it for her and I had the feeling she enjoyed it too. She also had these big, brown doe eyes that made guys melt.

Me, I was tall enough, I had hit 6'1" after my growth spurt but I was on the skinny side and I wasn't overly coordinated. I had the same color hair and eyes as Gemma but on me they seemed more plain. Thankfully, the other thing we had in common was that neither of us suffered much from acne. I wasn't as tanned as Gemma, mainly because I didn't use tanning beds during the winter like she did, but I did swim during the summer and both of us were a little dark skinned naturally, so I did have some tan.

Another thing that I had inherited from our dad besides my height was that by the time I was 16 I developed a bit of a hairy chest. It was at this age when the tables turned and I found Gemma at my mercy. It was her last year of high school and she would be graduating soon, when providence fell into my lap. Something called senior prank day.

For Gemma, senior prank day became horribly out of control. Other groups of seniors pulled off pranks that while funny, were pretty harmless. Her group took it up a notch. A few notches thanks to alcohol and that a couple of the guys in her group who were assholes.

What started off as some graffiti painting on the school, bad enough, turned into vandalism. Windows were broken and property was damaged. They were smart enough, or lucky enough to stay off surveillance cameras. I'm going for lucky. Police were involved, kids were interviewed, but nothing concrete came out. Too be sure, the school had l list of people they suspected, but it looked like the perpetrators were going to stay in the clear. Until I was cleaning stuff in the garage that is.

That's when I came across some things in a bag tucked behind some boxes. In this bag were a few empty spray paint cans, a shirt with paint on it, and lo and behold, a memory card. I downloaded the card onto my computer and what did I see, my sister and friends committing the fore mentioned crimes! knew I had her right where I wanted her. My sister wasn't the kind to come up with this herself, most likely it was another case of going along with the group in order to save face with her friends. I had been suspicious anyway, knowing her crowd and also by the way she had been acting.

Now I had to decide on what payment I would extract for my continued silence. I knew if this got out she would be in a level of trouble like she had never been in before. Truth be told, I most likely wouldn't have ratted her out. Her friends in a heart beat, but that would have meant her also. She didn't know that though. I knew I was going to have to play this good.

That night it came to me. My plan was more devious than I had ever been. As I thought about all the times she tormented and teased me, it came to me. The cost for keeping quiet was going to be for her to pose for me and my digital camera. She thought I was perverted before, she hadn't seen anything yet.

The next evening after dinner it was my turn to call her into my room and spring the trap. Gemma came into my room, much less cocky than was her norm. It almost took the wind out of my sails.

"What do you want," Gemma asked.

"I wanted to show you something," I answered.

"What," Gemma asked with a sigh.

It was then I pulled up the pictures on my computer. The expression on her face was priceless.

"Where did you get those," She stammered?

"You didn't hide things very well," I told her.

"Who else has seen these"?

"No one yet".

"You're not going to tell anyone are you"?

"That's up to you dear sister," I replied smugly.

"Do you know how much trouble I'd get into,"? She pleaded.

"Yeah, I do".

"You can't tell anyone. It wasn't my idea, I didn't know all that was going to happen. Please, don't tell anyone user," Gemma practically begged.

"Like I said, that's going to be up to you. Do what I want and your secret stays safe".

took a deep breath and told my sister what it was going to cost her, everything I wanted from her. At first she just sat there and just stared at me.

"You want me to pose for your pictures," She asked disbelieving.

"Yes. Friday night when mom and dad go to their dinner party you're going to pick out a couple three sexy outfits and model for me. Then you'll strip for me, naked, completely naked, and when I have the pics I want, you're in the clear," I stated firmly.

"You've got to be kidding user. I'm not doing that and I don't think you'll really show those to anyone," Gemma said, calling my bluff.

"Up to you, I can print these off right now. A copy for the folks, some for the school, maybe even sell them to the news, who knows," I said, shoring up my courage.

"Jesus, you really are a pervert. I can't believe you want to take naked pictures of your own sister".

I shrugged my shoulders, "Think of it as Karma, for all those times you teased me. No teasing this time".

"There has to be something else. Do your chores, be at your beck and call, something," She pleaded.

"That's the deal, it's non negotiable," I said, holding my ground.

Gemma sat there silent for a few minutes. I knew she was weighing her options and gauging just how much trouble she would get into if this got out. I could see her hands were trembling a bit.

"If I agree and I'm not saying I will, what are you going to do with the pics,"? Gemma asked.

"These go away, the ones I take stay hidden," I answered.

"No web sites or You Tube or anything"?

"Nope".

"Why do you want them then," Gemma asked suspiciously?

"Like I said, Karma, simply pay back," I told her.

"You're probably going to beat off every night to them, pervert," Gemma said angrily.

"You can tell me tomorrow, deal or no deal," I said, refusing to be baited.

"You're serious," She asked.

"Very. Good night sis," I said, turning back to my computer. Gemma got up and left my room. I let out a heavy breath after my door shut. My hands were shaking and I felt almost dizzy. This was the first time I had taken control of a situation with my sister. I felt almost liberated. I also didn't realize just how momentous this was to become for us both.

The next morning at breakfast Gemma quickly walked behind me as she was heading out the door for school.

"Deal," She whispered as she passed behind me.

Nothing more was said. The next couple of days Gemma avoided me at all costs. She didn't talk to me at all. When Friday came I was a bundle of nerves. I was still half convinced that Gemma would bail out on the deal. I couldn't wait for school to get out.

At home, I quickly went to my room and waited, killing time on my computer. Around 5 o'clock my dad poked his head in my room to tell me that he and my mom were leaving and that there was food in the refrigerator if I got hungry. I heard him repeat the speech to my sister next door. My stomach was in knots. A few minutes later I heard my parents leave. About 15 minutes later Gemma poked her head into my room.

"Well, let's get this over with," She said to me.
