She learns something new about herself

Cold water struck Lilian's skin as she entered the shower. The freezing water doing nothing to cool the primal heat she felt within her.

She still needed to condition her hair and scrub herself down but her mind was enveloped with thoughts about what had just happened.

Things had certainly gone to far between them. Her own brother treating her like an object he owned and could use how he pleased. What was worse was how tingly it had made her feel, how good she felt every time he talked down to her. Not to mention the kiss!

She'd stared right into his eyes as he took her first kiss while his hands carelessly groped her most sensitive areas. Sure they were just role-playing a history lesson, but that didn't make what happened any less real. She knew it was wrong to kiss her brother like that, wrong to let him treat her that way.

So why did she want him to do it again?

She couldn't really be the kind of person that wanted to be treated like this, could she?

Her mind knew she needed to tell him to stop but her heart pulled in the other direction. No, not her heart. A deeper, lower part of her base self was what was crying out for more. Like a starved animal given its first scrap of food, it overpowered her logical mind with a hunger for more.

She turned off the water and called out for her brother, the words slipping out of her mouth before she could change her mind.

"Master. I've finished showering for you. Do you have something I could dry myself with?"

"Just a sec." Came his distant reply.

She wait, still dripping, for her brother to give her something. As the anticipation of his return built, she made an impulsive decision.

"You can dry yourself with-" He stopped mid sentence after opening the bathroom door, taking in the sight of Lilian waiting for him on her knees.

"Welcome back Master, thank you so much for bringing me something!"

"You're a natural little **** girl aren't you." He said, his breathing getting deeper. "I brought you some of these to dry off with."

He threw two small prices of cloth at her and watched with anticipation as she realised just what they were.

"Are... are these a pair of dads boxers and mom's panties?"

"Both used."

She felt her breath tightening in her throat as he said those words. Did he really expect she would do something as demeaning as dry herself off using their parents used undergarments?

She wouldn't.....Couldn't.....It was beyond a step to far....

But somehow, for some strange reason, knowing that only made her need to do it even more.

Her whole body shook as she began rubbing herself down with them. Slowly and carefully rubbing them across her wet skin as her brother looked down on her.

Despite being used the underwear wasn't particularly dirty, but the slow act of rubbing herself with them made her feel filthier than she'd ever felt before.

She turned around and bent herself down to dry off her ass. Carefully rubbing each cheek down as She swayed back and forth.

"Don't forget to dry off that sweet pussy of yours." Damian told her. "I know it's the wettest part of you right now."

He was right, she was wetter there now than she had been in the shower. She rubbed both pairs across her aching mound, pushing slow and hard as indecent sensations shivered across her body.

"You like masturbating with you parents dirty underwear you little **** slut?"

"Is this masturbating master?"

He moved closer to her, resting his hands on her ass cheeks as she continued rubbing herself.

"You've really never even touched yourself? Well it feels good doesn't it?"

"It feels really good." She moaned the words out, her eyes closed as she bit her lips from the pleasure. "But doing it like this also feels wrong."

"It's natural to touch yourself or 'masturbate', no reason to be ashamed of something that makes you feel good."

"But..." She started, hesitating before choosing to finish her thought. "But what if I like that it feels wrong?"

Damian went still, stunned and at a loss for words at her admission. Lilian stopped too, worried she'd pushed things to far until she looked back and saw his eyes. A dark fire raged behind them and she knew there'd be no holding back now.

"Well." Damian said. "Well I guess that would make you a filthy degenerate whore that gets off with her mothers filthy panties."

The words hit her as hard as a slap to the face would have. Each degradation making her ache harder for more. She started to rub herself again, harder and faster, but Damian grabbed her hand and pulled her to her feet. Her ripped their mother's fullback panties out of her hands and stuffed them into Lilian's mouth. The wet taste of her own nectar mixed with her mothers scent dripping down her throat.

"Come with me slut. Let's get you an outfit worthy of perverted piece of trash you are."
