Showing my Sister Part 1

Showing my Sister

by Vanessa Evans

Part 01

There is something about the relationship between Mary and her older brother Zack that you just can’t put your finger on. Usually they are just like your average brother and sister but sometimes there’s something between them that I’m having real trouble describing. I’ve considered words like atmosphere, tone, energy, connection, karma, love, admiration, conveyance and vibe, not none of them correctly describe what is invisibly there.

The thing is, whenever Zack tells Mary to do something, she just does it. She never questions the order, she just does it. She knows that she is doing what she is told and will talk about doing it with Zack but to other people she never says,

“Zack told me to do it,” it is always, “I don’t know why I did it. I just did it.”

This all started when Zack jokingly told Mary to wash his bike. Zack fully expected Mary to refuse and tell him to get lost but she didn’t, she got out the hosepipe and a sponge and washed off all the mud that had accumulated on it when Zack and his mates had been riding through the woods.

Zack was dumbfounded, I mean what boy’s sister would do that for him, its just crazy, but Mary had done it without questions or complaints, even smiling at Zack when the job was done.

Zack quizzed Mary afterwards, asking her what she’d broken in his room, what she wanted from him, and other such things, but all she said was that she wanted nothing in return.

A few days later Zack was still trying to work out what Mary wanted from him, they were home alone for a couple of hours so Zack thought that he’d experiment to see if it was a one-off or what. He told her to go and get him a glass of juice and a biscuit, and she did, no questions and nothing in return.

Over the next days and weeks Zack kept trying to work out why Mary was acting like that, and only with him. Okay, she always did what their parents told her, but usually refused to do the silly things that her friends told her to do.

Zack eventually forgot about it and they continued like your average brother and sister. It wasn’t until Mary was 18 and at college, and their parents were out shopping one Saturday that Zack got reminded of those incidents all those years ago. Mary was in the shower and she had forgotten to lock the bathroom door when Zack walked in to go for a pee. Mary was behind the shower curtain with the water pouring down on her when she realised that someone was in the room with her. The shower curtain was white so the couldn’t see who it was so she screamed.

Zack stopped walking to the toilet and said,

“Relax Mary, it’s only me.”

Mary stuck just her head round the side of the curtain, saw Zack and said,

“Get out Zack, you shouldn’t be in here.”

“You didn’t lock the door.”

“But I’m naked.”

“Are you?”

“Of course I am, I’m having a shower, get out.”

Zack suddenly remembered Mary always doing as he told her so he thought that he’d see if he still had whatever power it was still worked on Mary so he said,

“Show me.”

A spilt second later the shower curtain opened and Zack saw his not so little sister in all her glory. She was just standing there with one hand on the shower curtain and the other by her side.

“You look good sis, turn around and let me see your butt.”

Mary let go of the curtain and turned.

“Cute little butt sis. Finish your shower, get dried then come outside to the back yard and bring a beer for me. Loose the towel and don’t put any clothes on.”

Mary turned and got on with her shower.

Zack couldn’t believe his luck and he had trouble having the pee that he went in there for. As he washed his hands he looked to his sister, she was soaping her arms and the curtain was still wide open.

“Crunch time.” Zack thought as he went back outside and sat where he had been before.

Five minutes later out walked Mary, totally naked and with a bottle of beer in her hand.

“Thank you Mary, have a seat and enjoy the sun.”

Mary did and they talked for ages and about all sorts of things with Zack getting glimpses of his little sister’s tits, bald pubes and the front of her slit. Zack was just thinking about telling her to go and get him another beer when he heard their parents car enter their drive.

“Go and put your bikini on Mary.” Zack said.

Mary stood up, turned and went into the house with Zack looking at her cute butt as she walked.

Zack stood as well and went to see if his parents needed a hand carrying anything and when they didn’t he went back to the chair and enjoyed the sun.

Five minutes later Mandy was back, and she was wearing her bikini.

“This is weird.” Zack thought, and he again tried to work out what the hell it was that was causing Mary to do whatever he told her.

Mary spread the towel that she was carrying on the grass and lay on it on her back with Zack watching her and still trying to work out what the hell was going on.

Ten minutes later their mother came out and told Mary that she should have gone to the beach saying that it’s much better sunbathing on the beach than the back garden.

“Can I borrow daddy’s car tomorrow please?” Mary asked.

“He needs it tomorrow but I’m sure that Zack will drive you there won’t you Zack? Maybe spend the day together at the beach.”

Zack thought for a second then said,

“Sure, why not, I haven’t been to the beach for ages.”

It’s only about 30 minutes to the really nice beach that is out in the middle of nowhere with a car park at one end and at the end of the dead-end road that goes there.

Zack’s mind started to go into overdrive. Although they’d been there lots of times when they were kids he’d recently heard a rumour that some people sunbathed naked there. Could he get Mary to strip naked there?

His shorts started to change shape as he thought about his sister naked on the beach. Would there be lots of people there who would see her? Could he tell her to masturbate on the beach in front of some strangers. Poor Zack had to start thinking about something else to avoid having an accident in his shorts.

He thought about it some more in bed that night and had to use some tissues to avoid leaving his mother some tell-tail signs when she changed the sheets.

At breakfast the next morning their mother asked if they were going to the beach for the day. Mary looked at Zack who looked at Mary and said,

“Yes we are, probably stay there all day unless the weather breaks.”

“Okay,” their mother said, “don’t forget to take some sunblock and a snack for lunch.”



With that their mother and father got up and left them. When they were doing the washing up Zack said,

“Put on your shortest dress Mary, and don’t bother with any underwear.”

Mary smiled and said,

“Yes Zack.”

Thirty minutes later Zack’s car was reversing out of the drive with Mary sat beside him. She was indeed wearing an old summer dress that was quite short and her pokey nipples told him that she wasn’t wearing a bra.

Zack felt his cock stir.

Thirty minutes later the car was pulling into the car park. It was still only mid morning and there wasn’t a lot of cars there but Zack suspected that that would change as the day wore on.

When they got out of the car they went to the back of the car to get their belongings. Zack opened it and Mary bent over to put the things that had fallen out of the bag back in before lifting it out. Zack had taken advantage of the unexpected situation to take a step back and look to see if Mary’s dress had ridden up. It had, and he could see her bald pussy between her cheeks.

His cock stirred again.

They walked the short distance to the beach with Zack trying to decide if he wanted them to sunbathe near the path between the car park and the beach, or in the dunes a little way along.

Zack decided near the path and he looked around for a spot and walked over to it. He reckoned that people walking from the car park would easily see what he hoped would be the naked Mary.

“Let’s stop here for a while Mary, we can maybe move to the dunes later.”

“Okay Zack.” Mary replied and they put their bags down and spread their towels.

Mary was just starting to unbutton her dress when Zack said,

“Don’t bother with the bikini Mary, you’ll only end up with tan lines.”

“Okay.” Mary said and continued taking off her dress leaving her stood there totally naked.

“You look good sis.” Zack said as they both lay down, Mary on her back and Zack on his stomach to hide the bulge in his shorts.

They were silent for a while, Zack watching the handful of people arriving and looking at Mary as they passed quite close to them.

Poor Zack, his brain just could not work out why Mary was acting the way that she was. Nude on a beach just wasn’t the Mary that he grew up with, was it really possible that he had some magical power over her?

About an hour later Mary turned over then asked Zack to put some sunblock on her back. There was no way that he was going to refuse so he got up onto his knees and started up by her shoulders. As he worked his way down her back Zack said,.

“You do want me to do your butt don’t you Mary?”

“Yes, of course, all over.”

Zack rubbed the sunblock all over her butt and into the crack.
