Good Boys Don't SNOOP! (RogueDevi & DuxT)

Eliza yawned as she stuck her key into the front door. It was nice that she and her brother could come to the summer house for once without their parents, and she relished every opportunity to wear her new swimsuit out on the beach. Or wear it like it was now, slightly damp and clinging to her body tightly, the scant fabric hardly concealing her nipples or the other curves of her body. She was slightly disappointed though. It wasn't like her brother to refuse to go to the beach with her, stomach ache or no. She had tucked him in his bed like any big sister should (despite the fact they were both far older than that behavior would indicate), and went by herself.

She had yet to fully...explain herself to him. Not that she was concerned about that really. It was clear since they first reached puberty that they had more than, well, familial ties to each other. More than once she had teased him about it. Edged him on a little, and he--the quiet and more submissive one of the pair--seemed to be absolutely fine with it. But she had begged her parents to let them have the summerhouse to themselves for a reason, and she was more than agitated that despite the duffle bag under her bed, she hadn't got to that reason yet.

She shook her head and then started heading up the stairs to her brothers room. It wasn't like it mattered anyway. She would find a reason soon enough to confront him with her feelings. Maybe she should---
She blinked, standing on top of the stairs looking down the hallway where the bedrooms were. She was sure she had shut her door when she left, yet there it was slightly ajar and she could hear movement. Her ears shifted up on high alert and she crept quietly to her door a strong wave of anger rising in her. The little sneak! She HATED it when people went into her room, what was he doing anyway? She sincerely hoped that he wasn't offended or angry about what was in the bag under her bed...

Finally reaching the door she pushed it fully open to see her brother ruffling through her underwear drawer, his left hand already clutching one of her black lace thongs.

"I take it you have recovered from your stomach ache, eh?" Her voice coldly piercing the silence as she looked at her brother.

"Looking for buried treasure?" She mused in a serious voice as she walked in and closed the door. As she turned around a wicked smile was on her face. She finally found her excuse.

Alex had loved and hated this time at the summer house. On the one hand he loved spending time with his sister, at the beach too was a huge bonus. On the other, this time with his sister had been torture and the beach didn't help! Since he'd hit puberty Alex couldn't help but have dirty thoughts about his older sister. He knew it was wrong, but he just couldn't help it sometimes, especially with how she seemed to tease him at times. This trip was no different, every time he went out with her he could barely tear his eyes away of how she looked in that swim suit.

So that's why he'd faked being sick today, he needed relief, desperate, desperate relief. After she was gone he'd began with his usual method, regular masturbation. This along with some porn usually did the trick, but with the summer house not having internet set up, he didn't have the porn. Try though he might, he just couldn't get himself off.

It was a good half hour later and the boy just lay there over the covers, briefs dangling from one ankle. His six inch cock stood painfully erect as he lie naked and frustrated. He had to get this sorted, he couldn't go another day of teasing and seeing his sister without some sort of relief. That is when inspiration struck him, his breathing slowed as he thought about it. His sister wasn't home still, what if he used something of hers to help. It wouldn't be that wrong would it?

Before he'd really even questioned the idea further, Alex stood in Eliza's bedroom, still as naked as just a moment ago. He opened up her underwear draw, his eyes going wide as he looked over it all. His breathing quickened again, he couldn't believe he was really doing this. Quickly he got to work, his hand soon pulling out a black lace thong, his mind racing as he thought about Eliza wearing this. Without really thinking about it he pressed it to his nose and sniffed.

That is when he heard his sisters voice and the knot that was forming in his stomach dropped. The boy froze, his tail bolt straight behind him as he tensed. He slowly turned to face Eliza, gulping audibly. "Sis... I...I can explain!" His tone clearly panicked as he tried to think of an excuse. Granted there really was no good excuse to being naked in your sisters room, penis fully erect, holding her panties.

"Can you," she said in a sugary false kindness, "I would love to hear it." She walked over to him, and gently took the panties out of his hand and closed her dresser drawer. She looked at him with hungry eyes, lingering on his rock hard cock, and his round ass. She ever-so-slowly went to the tie of her swimsuit top and released it with a slow pull. Her glistening breasts with perfect pink nipples at attention came in view as the scarlet scraps of fabric went to the floor. "Were you looking for something to wear yourself?" She joked playfully, sliding a fingertip down his spine and lingering right at the top of his crack as she leaned in to breath in his ear. "Cause I bought those for you to see me in. Not the other way around." she whispered delicately into his ear her exposed chest touching the side of his arm slightly.

She walked to her bed, bending over to get her bag from underneath. She took her time, wanting to give her little brother ample time to enjoy the sight of her curves before setting the duffle on her bed. She then pulled on the strings to her bikini bottom letting it drop to the floor before leaning on her bed facing him. Her tail swished softly, an undeniable sign of her excitement of what she was doing. "Why don't you come sit up here?" She said patting the space next to her. "I have some explaining of my own I think."

His jaw dropped as she undid her top, his eyes going wider as he stared at her breasts. His mind had gone far away from what she was saying as she made her joke, the part that was still looking for an excuse though latched on. "Yes that's it!" He realised his mistake a moment later, his cheeks going pink. "Wait, no...no.. that wasn't it." The boy stammered, the nervousness clear his voice. He gave a shudder as his sister pressed against him, giving a small gasp as her finger traces down his spine, around his tail base and to his crack.

As she pulled away again he watched, still too shocked to know what to make of all this. This had to be a dream, this couldn't actually be happening. However as he watched her bikini bottoms fall he couldn't deny any more that he really wanted this to happen. At her invitation his tail twitched, seeming his body was considering bolting from the room and hiding. However he swallowed his fear for now and moved to her, sitting where she gestured, apprehensive about what was going to happen.
