Chapter 1

It first happened in school — my sister and I are a year apart but run into one another from time to time. I'm 16, my name is Winston, She's 15, and her name is Gloria.

She is very pretty, and I occasionally will come up behind, give her a kiss on the neck, wrapping my arms around her waist. I only do this if there are none of her usual friends around. I may be horny for my sister, but I'm not stupid.

When I first started doing this, she pushed me away telling me, "Don't touch me, you pervert?" and shook me off her. After doing it as often as I had, she now would say, "Oh, Jason, that feels so good." She'll giggle and walk away, proud of her new retort.

I only ever did this at school — at home there was too much to lose. Yeah, that reasoning is a little fucked up, but my sister is pretty, and I like to touch her, hold her and kiss her. She is very slowly coming around.

I needed to change up what I say when I approach her; I had some ideas floating in my head all weekend.

School started up again the following Monday, and between classes, I went up to her from behind, gave her a kiss and said, "I love you sis," as quietly as I could. She took my hands and whispered back, "I love you too, pervert," giggling as she walked away. This was becoming quite the little game between the two of us. Twice more that day I did it, using the same riposte.

She was starting to giggle each time lately. I needed to say something that would surprise her, something more outlandish, possibly.

On Tuesday at school, between homeroom and next period, I went up behind and said, "You are so pretty," She put her hands over mine and said, "I know, pervert," then slapped me away.

Bu the end of the week, I had run out of smart-ass things to say, so I decided that on Monday, I would 'take it up a notch.'

After third period, I found her and quietly said, "Glory, you make me hard."

She turned and looked at me for a moment, then slapped my face and walked away — that was new. I found my new regular expression! I used it only one more time that day, and she had the same exact response.

By the end of the week, she was still responding with a slap. This weekend I would find the time to talk to her about it.

On Friday night, there was a knock on my door. I yelled, "Come in." it was Glory, and she sat on the edge of my bed.

"Win, why are you saying, 'You make me hard?' Do you even know what that means?" she said, looking down at her hands.

I moved from my chair to next to her and touched her chin, bringing her eyes to mine and said, "I know exactly what that means and it is a true statement, Glory. I know a brother shouldn't say something like that to his sister, but every word is true."

She got up, slapped me real hard and said, "You're just a pervert, that's all you are."


In response to her slap, the following week, I completely avoided my sister, barely recognizing that she existed. On Friday night real late, there was a knock on my door.

I was still up, but ignored it. About a minute later the rap on the door started again, followed by a voice saying, "Win, let me in?"

I got up off my bed, opened the door and said, "What do you want?"

"Don't you love me anymore?"

"What are you talking about, sis?" I replied.

"This last week, you never came up behind and talked to me," she expounded.

"You called me a pervert, so I figured you wanted me to stop," I said.

She started to cry as I walked her to my bed where I helped her sit down.

"I called you a pervert ... because — because I liked it," she said.

"You like ... what exactly?" I asked perplexed over her words.

"I liked it when you came up behind me and put your hands on my waist."

"You did?"

"Yeah, especially when you got right up behind me. You felt nice, your hands felt nice — everything felt nice. Especially when you had started to tell me 'that I got you hard!' I could feel your hardness up against my butt. I actually got turned on by it," Glory said.

"Now who's the perv?" I said.

"Stand up for a minute, and get behind me?" she asked.

"Sure, why not — I haven't been slapped in a week, and i am a sadomasochist at heart."

She had stood up, and I got behind her,

"Closer, silly," she said.

I got up right against her, including my hardening dick pressing against her nice firm butt.

I heard her moan a bit, so I backed off a little.

"Get back there, up tight, please?"

I did, putting my arms around her pushing real hard against her.

"Put your hands on my breasts?"

"What..."

"Please, put your hands on my breasts, Win?" she said with a stutter in her voice.

I did and they felt really nice, I never touched any girls breasts before, but she knew that, since we talked to one another all of the time about those kinds of things.

"Glory, I've never been so hard before, are you sure you want me to keep doing this?"

"Yeah, Yes —yes, please Win -- keep touching me, don't stop. Squeeze them please — oh yeah, I feel your hardness against me and your hands on my tits, oooohhhhhhhhh!"

I think she just had an orgasm, and I'm about to cream my pants as well. I pulled away, tore off my pants and put my hand on my dick and I came all over my underwear and my hand.

My sister had turned to watch, as I said, "Damn sis, you made me cum!"

"I have to take a shower," she said.

"Can I join you, Glory?"
