Ask her brother for help

She regretted her decision as she entered his room as the foul stench assaulted her senses. Despite being twins, she and her brother were opposites of each other.

While Lilian's room was light, clean and organised. Her brother, Damian, kept his room dark, had his clothes littered around floor and despite her not being able to remember the last time he was sick, he still had crumpled tissues on his computer desk.

He was still in bed, not wanting to attend a regular school like her, and looked up at her with wide eyes betraying his shock at seeing her. While she rarely came to his room his shock seemed a little surprising to her but she had little time to give this more thought.

"Hey Damian, I need to cash in a favour" she said as she walked into the room.

She was still bare footed and felt herself walk on a strange rough texture. She picked up the object and after giving it a close look realised it must have been an old sock of his.

"Eww I didn't even know old sweaty sock could get like this." She exclaimed, bringing the sock to her noise and giving it a few cautionary sniffs.

"Gross" she remarked "I know you like your room how you have it but I can help you give it a clean later if you want?"

Damian stared intently at her while she held the old sock close to her face. It looked to her as if he wanted to tell her something, but she was never particularly good at knowing what people, were thinking.

"That's not..." he started, before biting his bottom lip and dropping that line of thought.

"Never mind and I don't owe you any favours right now, I'm all paid up." He said, sitting up in his bed and out of the sheets.

He was topless and Lilian supposed he must have slept naked like her. Despite the cool air in the room and his state of undress he seemed to have worked up some sweet somehow.

"No wonder his socks are like this" she thought to herself while idly feeling the crusty texture of the sock in question.

"Well let me clean up all this filth later then" She said gesturing to his clothes as she threw the sock back into the pile.

"Alright just..." Damian said, loosing track of his thoughts as he noticed Lilian's nipples poking through her shirt in the cool air of his room.

"Just tell me what you need and I'll help out" He finished, now blatantly staring at her chest.

Damian's parents tried to shelter him like his sister, but unlike her he found his way around the strict internet filters. Lilian had always been the favourite child, while his apathy and aloofness saw him fad into the background.

Damian knew it was wrong to stare directly at a girl's tits like he was, doubly so when the tits belonged to his sister. However he also knew, with his parents being the way they were, she may be the only girl he would interact with for years to come.

Lilian barely noticed he wasn't looking her in the eyes anymore, she was too busy worrying about how much time she had.

"I lost my underwear in my room some where and I need you to help me find it before my first day of school!" She exclaimed, gesturing for him to come with her as she turned and left the room.

Daiman was very thankful that she left when she did because there was no way he could have kept the guilt from showing on his face.

Looking under his bed sheets at his sisters panties, now coated in a thick layer of fresh cum, he wondered how far her naive innocence went.
