Sally stumbled in the door to the kitchen. Stacy, her sister was waiting for her, sitting on the counter. "Your late little sister. Where have you been? You don't look like you want to run into mom or dad right now."
"I was out with Kevin. Please don't tell them! I'll do what you want. They can't find out we messed around."
"What will you do for me? This is serious. You've been drinking and out with a boy."
"I'll do whatever you ask for a month, whatever it is. I don't care, just don't say anything."
"Your on, little sister. First let's get you cleaned up."
Stacy took Sally by the arm and led her to the bathroom. She pushed the door open and led her sister in first, what a tight little ass she had and a great set of hooters, they got to be d-cups easily. Stacy turned the water on in the tub, and started to fill it up. She turned her attention back to her sister. She pulled her red hair back from her face. Her green eyes showed a bit of sadness with thankfulness. Stacy couldn't stop herself; she leaned down and kissed her sisters lips. Sally gently kissed her back and tried to put her tongue in Stacy's mouth. Stacy regained control and removed her sister's shirt; she threw it to the ground. She unhooked her bra and tossed it. Stacy looked down at her sister's chest, which wasn't weird. He sister was five-six and she was five-ten. Wow, amazing she thought. I wish my boobs were big like hers. I got smaller c-cups. She had to bend down as she unfastened her sister's pants. She slid them down and helped her step out of them. She went to pull the panties down, but to her surprise only a clean shaven pussy was in front of her with a little arrow pointing down. She helped her sister into the tub. She threw caution to the wind and took her clothes off. She double checked the door to see if it was locked and slid into the tub behind Sally. "We haven't been in the tub together in years. It's nice having a big sister that will take care of you no matter what."
Stacy took the washcloth and started to wash Sally's back and shoulders. She reached around the front of her sister with both hands and put soap on her breast. She rubbed it in good, perhaps a bit too good. Sally laid her head back on her sister and whispered, "Your hands feel good on my boobs."
Stacy moved her hands off. She didn't want to give Sally the wrong idea. She cleaned Sally's back, stomach and legs. Sally took her sister's hands and guided them between her legs. Stacy cleaned the outside of Sally's lips. Sally then pushed one her sister's finger inside of her. Stacy started to pump her hand in and out. Sally started to moan a bit. Stacy then realized who this was she was fingering. She pulled her fingers out and stood up. "Where are you going? We were starting to have some fun like we used to."
"You're my sister and drunk. I can't, not right now."
Stacy helped her sister out of the tub and dried her off, careful to avoid her breast and slit. She dried herself off and pulled on her robe. She put Sally in her bed after giving her a set of pajamas from her drawer. She walked down the hall to her room, far away from her sisters and her parent's room. Right of being the oldest, she was twenty-four and her sister was only twenty-one. She slipped into her favorite pair of pink panties, with little cherries on the front, right above her clit. She slid a pink night shirt on over the top. She walked over to her bed and fell in, pulling the covers on. She couldn't stop thinking what Sally made her do. That's right Sally did it, not her. Still it was getting her hot. She couldn't fall asleep. Her hand found its way up her shirt and she started to massage her small breast. Her nipples were getting hard and her groin was getting wet. Her other hand ran down her stomach and found its way to her mound. Her panties were more soaked then whenever she masturbated in the past. She rubbed her clit for a few minutes, and then slid her hand inside of her panties. Her hand worked her bud, and then she slipped in two figures and pumped herself, slowly at first and then faster and faster. All she could think of was her same hand doing it to Sally. She moaned quietly. Then as she came, out of nowhere she shouted, "SALLY!!"
She didn't care if anyone heard. She would say she was having a bad dream. She drifted off to sleep.
The next day, a Saturday, the parents told the two girls that they were going out of town for a few days. They had business to take care of. The girls would be home alone. After the parents left, Sally walked up to Stacy and said, "What do you want to do?"
"I don't know. Do you remember last night?"
"What part? I got wasted and don't remember much. You did take care of me though."
"That's all, nothing weird or unusual?"
"Nope." Sally lied.
"We should watch a movie, then maybe play dress up like we used to when we were little, go through moms clothes. Remember?"
"Sure."
They put in a boring movie that Stacy didn't pay attention to. She thought about her sister. She must remember, if she didn't she was acting like she did. Sally was always a keen girl. Was she playing with her head because of the servant thing? She had to know. "Sally, you remember that you'd do anything I said? That I promised you I wouldn't tell mom or dad?"
"Yeah. What is it?"
"I want you to go and get me something to eat."
"Sure."
Sally did as she was told. She brought back some food, which Stacy ignored. "Now rub my feet."
Sally sat at the end of the couch and rubbed her sister's feet. Stacy admitted her sister was good at it. "Now my back. First I'll take my top off."
She had on a wife beater and a pair of boy shorts. She pulled the wife beater over her head and threw it at her sister, who swallowed hard as she seen Stacy's breasts. Stacy laid out a blanket and got down on the floor face down. Sally straddled her sister's butt and massaged her sister's back, moving her hips lightly back and forth. Then Stacy rolled over, so it looked like Sally was ridding Stacy. "My front is a bit tight. Work out the kinks."
Sally started with the shoulders. Worked her way around Stacy's small breasts and started on her stomach, same back and forth motion, gently brushed their groins together. Stacy waited a bit then moved her sister's hands up and on her breasts. Sally was getting confused. She was calling her on her bluff. She did remember last night. She wanted to do this for a while; Stacy was really going for this. One thing left to do before she knew for sure. She started to work her way down her sister's body and rubbed her hips. She slid her fingers into her sister's shorts and started to remove them. She half expected Stacy to protest but she raised her butt and let the shorts be removed. Stacy's pussy was glistening in the light. Stacy opened her legs, inviting Sally in. "It's not going to lick itself. Last night showed me that I really want you."
Sally bent over and kissed the inside of her sister's legs. She moved up her thighs and kissed her mound. Her pussy lips were so wet, and she was tight. Sally licked up her sister's cooch and flicked her tongue on her clit. "You've done this before, haven't you little sister?"
