That evening, at the urging of Candace, Mal and Lizzie, Jill approached Brittany's bedroom and knocked on the door. There were rustling sounds coming from the other side, then Brittany calling out:
"I'm coming, just a minute!" She sounded a little breathless.
Jill could have sworn she heard a zipper being pulled up as she waited for her cousin. She wondered to herself if her little cousin had been masturbating, a thrill shivering through her.
Brit was definitely every bit as beautiful as the rest of her lovely family. Maybe the possibility that she'd heard them fucking this morning wasn't such a bad thing...
"Ok, come on in!" Brittany called a moment later. Jill opened the door and walked in.
"Hey, Sweetie. How are you? You've been spending a lot of time in here today." she said, sitting on the edge of the bed.
Her eyes took in the sight of her sexy little cousin. She was laying on top of the made bed, wearing just a tank top and some jean shorts, and listening to her ipod.
"Oh, it's nothing. I just don't feel very social today. Nothing to worry about!" the younger girl said. Her cheeks were a bit pink. And was she breathing a little heavier than normal?
Jill breathed in through her nose, detecting the subtle but unmistakeable scent of female arousal. It made her pussy moisten.
"Ok, well, I just wanted to make sure everything was ok. You've been acting a little distant from the rest of us."
"Really, I'm fine. Just tired, I think." Brittany assured her.
"Well, alright then. We'll be eating in an hour or so, so you just come out when you're ready." Jill said.
She reached forward, grasping her cousin's hand, and could swear she felt a slight shiver from the younger girl. She stood, about to leave, then paused at the door.
"Brittany, this morning... when you came downstairs? You didn't... notice anything odd, did you?" she asked, turning back to look at her. Brittany looked puzzled.
"Notice anything? I don't think so... like what?" she responded.
"Oh, nothing. Don't worry about. Forget I said anything!" Jill turned, leaving the room, and shut the door behind her.
Curious about her cousin's behavior, she stopped outside the door for a minute and listened. A moment later, she heard a quiet moan come from inside the room, and immediately pressed her thighs tightly together.
'Oooh... shit...' she thought to herself.
She looked around, confirming the hall was deserted, before slipping a hand down her pants and rubbing her pussy. She pressed her ear to the door again, fully absorbed in the sound of her moaning little cousin.
She could hear Brittany's heavy breathing, her stifled whimpers, and it was driving her crazy. She instantly began to masturbate furiously. Her fingers pistoned in and out of her drenched slit as she listened. She slid her free hand up her shirt, squeezing one of her tits and clawing at her hardened nipple.
Suddenly, she heard Brittany cry out in ecstasy:
"Oh, fuck! Trish!"
Jill gasped. Brittany was fantasizing about her sister! The thought sent her over the edge, and she shuddered as she came, fighting to keep as quiet as possible.
Dumbfounded and exhilarated by her discovery, Jill had just enough time to pull her hands from her body and straighten her clothes before Tiffany and Jess walked out of the other bedroom, hand in hand and giggling quietly.
"H-hey girls! Ready to eat?" she asked awkwardly.
"Oh yeah, I'm starving! I've managed to build up quite an appetite today!" Jess replied with a giggle towards her older sister.
Tiffany laughed along with her sister. Not sure she quite got the joke, Jill chuckled too, trying to act as if she hadn't just been spying on their younger cousin. The girls quickly made their way to the kitchen to join the others.

That night, Jessica lay awake in her aunt's bed. She kept glancing sideways at Brittany laying next to her.
The younger girl was still, her back turned to her, and breathing slowly. Satisfied that the girl was asleep, Jess slipped from the bed, padding quietly to the bedroom door.
"Where are you going?" came her cousin's groggy voice.
Jess swore under her breath, and turned back to the bed. Brittany was looking back at her, appearing as if she was just waking up.
"Just heading to the bathroom." Jess lied. "Go back to sleep!"
"Are you sure you're going to the bathroom?" Brittany asked. She hesitated, then continued. "Are you sure you're not going next door to fuck your sisters?"
Jess froze, staring back at Brittany.
"Are you going to tell?" she finally asked, her voice even. Brittany shook her head, biting her lip softly.
Jess stepped back from the door, eyeing her younger cousin. Even in the darkness of the room, she could tell that Brittany's face was flushed. She looked so sexy, with the covers resting just below her chest, her tank top bunched up, revealing her flat stomach, her hair tossled.
Jess stepped back to the bed, and sat down.
