Akira Hashimoto's older sister was quite the bully to him when they were kids. Although the bullying came down as they grew older, they still had a mutually acrimonious relationship.

There were two things that they mutually enjoyed though and that was wonderful walks around the countryside and trips to the beach. They were things that they would commonly do together as a family about once or twice a month.

One time, on the beach, his eyes fell on her bikini bottoms and the way the material had started to pull around her body as she laid on the beach mat. To his great embarrassment, she had noticed him looking.

"What are you looking at, perv?" she had snapped and turned over onto her front.

Feeling shameful for ogling at his sister of all people and actually getting caught staring, he distanced himself from her and hung around a faraway spot for the rest of the day.

When the time came for them to pack up and return home, he was not looking forward to meeting the rest of his family. His parents were going to kill his ass.

However, to his surprise, his parents spoke to him normally and his sister gave him the usual cold treatment. He guessed that she simply forgot about it, which explained why she did not tell their parents about him. At least he hoped that was the reason. Akira himself forgot about this incident until a week later.

Akira had gone over to a friend and had intended on staying all day but his friend's parents returned and got into a huge argument with his friend so he beat a quick getaway. The weather was great so he decided to walk the mile or so back to his home. His parents were gone for the weekend leaving only Fumie at home. She was in their shared bedroom doing her homework earlier on. However, as he left, he had caught a glimpse of her watching him from the room window.

As he turned into his home, he wondered if the reason for that peculiar behaviour was because she planned on doing something secretive while he was gone. He walked round behind the house toward the living room. He caught a peek of something white behind the partially drawn curtains. "Hmm, what's going on here?" He wondered curiously, sneaking up to see into the side of the room.

His sister was seared on the couch facing the TV set and was wearing her favourite oversized T-shirt that exposed her legs. This made him recollect about the beach incident the previous week except this time the view he was receiving of her was even better. The T-shirt had rode up and he could see almost all her legs. Looking at his older sister's body without her knowing it was for some reason exciting but in a wicked way. She had brown straight hair that reached her shoulders and a firm rounded ass which he, even as her brother, had to admit looked pretty nice.

He could see the T shirt had ascended to expose a brilliant white pair of panties that contrasted with the rest of her skin. She extended out her arms and took off the T shirt.

"Wow, what a gorgeous pair of breasts," Akira could not believe he was getting to see them. She slumped back onto the couch. When he took a look at what she was watching on the television, he realised that she had sneaked into the secret compartment of his drawer in their room and took one of his adult films and brought it down to watch, thinking he would be away all day.

Akira's eyes travelled to her torso and followed the beautiful firm even abdomen he had admired so much in her bikini the previous week.

Being a voyeur had transformed his cylinder into an iron rod: it had never felt as hard as this.

She clearly was about to pleasure herself and it would only be a matter of time before she would be touching herself. "It's her turn to be shameful," He thought, and marched around the corner and into the living room. "What are you up to, onee-chan?" Akira asked.

The way Fumie jumped into the air and tried in a failed attempt to cover herself up was super comical. "A-Akira…!" she yelled, mortified.

Akira smiled smugly at the sight of his older sister's fully reddened face. After years of his sister continuously humiliating him, payback time had finally arrived.
