Amy's Step sister

Note : This story is completely fictional!

 Amy knelt in her 'secret place'. It was dark. The only light came in through a crack in the wall. When she and her father had moved into this house a year ago when her dad remarried, she had found this small cubbyhole behind a secret panel in her closet. She had covered the entrance with some clothes and hadn't told anyone about it. Whenever she wanted to be alone, she could come here and nobody could find her. Tonight she knelt, naked, here so she could 'pet' herself. She didn't know why it felt so good when she petted herself, but she knew she didn't want her parents to know. She was sure her stepmother would tell her it 'wasn't right'. She had overheard her stepsister getting lectured about it a few years ago, and now she knew why her stepsister did it.

Amy's stepsister Kaitlyn was 20 and Amy was just 18. Through the crack in the wall she could see into Kaitlyn’s room. She knew that Kaitlyn still petted herself, even after she was told not to. Now Amy watched through the crack to see if her sister would do it again tonight. Kaitlyn lay in bed, still, but not asleep. Amy was about to give up on her when Kaitlyn sat up in bed suddenly, then went to the window. Amy couldn't see the window clearly, but when Kaitlyn came back into sight, she had a boy with her. It was Andrew Thompson. Amy thought Kaitlyn had stopped going out with him because their mother didn't like him. "I guess not,” she thought.

Kaitlyn started kissing the boy and removing his shirt. She kissed his chest and licked his nipples. Amy thought how good that must feel as she flicked her own nipples with her fingers. Kaitlyn was now removing his pants. Andrew closed his eyes and licked his lips a little. Amy wondered what her sister was going to do. She watched intently as Kaitlyn retrieved Andrew’s penis from his boxers. Amy almost giggled. She could barely make out Andrew saying something like "Suck my cock."

Kaitlyn took Andrew's cock into her mouth. Amy wondered if she were going to eat it. She was almost relieved when she saw it emerge again from her stepsister's mouth, intact. Kaitlyn was licking it like a lollipop. She licked for a minute or so and then some white stuff squirted out of the end of it into Kaitlyn's mouth. After Kaitlyn had wiped the stuff up with some Kleenex, she lifted her nightshirt and sat down on her bed. Amy couldn't see as well, but could tell Andrew's hand was doing something. After a minute or two, Kaitlyn began so jerk around on the bed. Amy decided Andrew must have been petting her and decided it must feel really good. Kaitlyn finally lay still again. Andrew leaned over her and kissed her again. Then he put his clothes back on and must have left through the window.

All this time Amy had been petting herself very slowly. She wanted to make sure she didn't 'go over’, as she called it, too fast. Amy had decided the show was over for the night, but then Kaitlyn got up and went out of view. When she came back, she had pulled off her nightshirt altogether. Kaitlyn was blonde with fairly large breasts and a round butt to match. Amy licked her middle finger and moved it to her own butt-hole. Amy wasn't sure why she liked sticking her finger in her butt so much, but she knew that she'd like to stick them in Barbie's butt too. She slowly relaxed her ass-hole until she could slide about half of her middle finger into it. She continued petting herself with her other hand and she wiggled her finger in her bottom. This felt really great.

Amy looked up and noticed Kaitlyn on the edge of her bed with her legs spread, and she had a white cylinder of some kind in her hand. She seemed to push it into herself somehow. Amy had tried putting her finger in her privates, but it hurt too much if she pushed very hard. She found she could push her finger into her ass much further if she licked it enough. She was still watching her sister intently. Kaitlyn began to wiggle on the bed again, this time even more than with Andrew. Amy licked her middle finger again; getting it real wet with spit and stuck it all the way in her bottom. The sensation was too much for her and she almost whimpered as she went 'over'. When Amy looked back up again, she got a better look at the white thing Kaitlyn had had in her privates. It was about 7 inches long and about 1-1/2 inches thick. She wondered how it would feel in her ass and she decided that she was going to find out.

A few days later, Kaitlyn was out in the backyard in the pool. Amy knew her parents wouldn't be home for another 2 hours at least. She slipped into her sister's bedroom. Since Amy and Kaitlyn were the only kids, they had always had room to have separate bedrooms. Amy knew that Kaitlyn kept a lot of things hidden in her dresser somewhere, but from the view she had in her secret place, she could never quite tell where. She opened the bottom drawer and looked through the clothes in it. She didn't find anything. She went to the next drawer, then the next. The top drawer was hard to open. She pulled it open a little too far and the drawer slipped out and dropped to the floor with a loud thud. She hoped Kaitlyn couldn't hear that out in the pool. She quickly tried to figure out how to put the drawer back in, when she noticed something inside the dresser, behind where the top drawer went. It was some kind of box. She reached in a pulled the box out. Just then Kaitlyn rushed into the room. "Amy, are you alright?" she asked before she noticed the drawer. "Kaitlyn! I thought you were in the pool." "Well I was in the kitchen getting a drink when I heard..." She stopped realizing where they were and what her stepsister had found. "What are you doing in here?"

"Looking for this." Amy held up the long white thing she had seen her sister use on herself. "You're too young for that. What do you know about that?" Kaitlyn asked. Amy replied, "I know you put it in you the other night. And I know Alan was here."
"How did you know that?” Kaitlyn glared at her stepsister. "I can't tell. But I will tell mom and dad about Andrew unless you show me what to do with this."

"You little extortionist." Kaitlyn said almost admiring her sister's cunning. "Alright, what do you want to know?" Kaitlyn was still in her damp one-piece bathing suit. Amy's red hair was pulled back through a baseball cap. She had on a pair of shorts and a tube top to keep cool since it was so hot this summer. "Get undressed and show me how this thing works." Kaitlyn slipped out of her one-piece bathing suit and sat on the bed. "Hand me my box." Kaitlyn motioned to the box Amy had found in the dresser. Amy brought it to her. Kaitlyn pulled out a tube and the white cylinder. She held up the white thing and said, "This is a vibrator." She indicated the tube in her other hand. "This is KY jelly. It makes things slippery."

"Where did you get them?" Amy asked. "Aunt Mary gave me the vibrator and told me how to give a blow job, like I did to Andrew. She said it would help me keep the boys happy, and the vibrator would keep me happy, and I wouldn't end up pregnant. I got the KY at the hospital. It's been pretty easy to sneak some out since I'm volunteering at the hospital on Tuesday and Thursday mornings this summer." Kaitlyn flipped the cap open on the KY and squirted some of the clear lube onto the vibrator. She put down the KY on the bed beside her. "You wanted an education, sis? Well this is my pussy." She pulled back the lips around her pussy. "And this is my clitty." She flicked it lightly with her finger and bit her lip a bit with pleasure. "Do you ever play with your clitty, Amy?"

Amy was watching mesmerized by Kaitlyn’s forwardness. She nodded silently. "Take off your clothes, Amy. I want to see you play with yourself. Pet your clitty for me." Kaitlyn said. Amy pulled off her shorts and underwear at the same time, and then removed her tube top. She had been in control before, but now she was so rapt in this scene from her dreams before her, that she could not help but obey. She knelt down like she had so many times in her secret place, and began to play with herself. She started to lick her middle finger, but decided she should not play with her ass until the time was right.
"I'm about to fuck myself with this vibrator." Kaitlyn said as she smeared the jelly around the entire length of the white shaft.

She lay back and slid the vibrator ever so slowly into her pussy. This time Amy had a superb view of what was happening. She flicked her clitty as she had seen Kaitlyn do before. Amy jumped; startled at the intense pleasure it sent through her. She did it again, and again. In just a few minutes she was going over. She let herself gasp out loud. "That's right Amy. Cum for me. Cum for me Amy." Kaitlyn coaxed. When Amy had partly recovered, she could see Kaitlyn pounding the vibrator into herself furiously. Seconds later, she was cumming too. After a few minutes both had recovered. "We'd better clean up quick. mom and Dad will be home soon." Amy agreed and the girls got dressed and cleaned up everything.
