"Have you seen your sister?" Hillary's mother asked from the bedroom door.
"She went down to the cabin to see what Michael's doing," Hillary answered. She was lying on her bed reading a book.
"They spend an awful lot of time together these days."
"I know," Hillary replied, hearing her mother's concern. "Isn't it great that Michael is finally starting to warm to the family?"
"I guess," her mother shrugged, but then changed the subject and added, "Pa and I are going to town. I was wondering if you two wanted to come with us? The preacher's brother is in town and he has some kids your age."
"Any cute boys?" Hillary asked with a raised eyebrow.
"Cut that out young lady!" her mother snapped. "This is the preacher's kin we're talking about."
Hillary fought off a smile as she thought about the last time she saw the preacher's daughter Ginny. She could still remember the softness of the girl's lips and the taste of her mouth. Ginny tried to act disgusted when Hillary kissed her, but Hillary knew the truth.
'Maybe I should go just to see how Ginny handles it?' she thought to herself, but then shook her head. 'No, I'm going to wait and see if Ginny comes to me like Michael thinks she will.'
"Sorry ma," Hillary said, not really sounding it. "I'm not really in the mood. Besides, I'm in the middle of a good book. You and pa go visit the preacher. Heidi and I will meet his kin at church Sunday."
"Are you sure?" her mother asked. "The preacher specifically asked that I let you and your sister know you're invited."
"What about Michael?" Hillary asked, wondering if the invite came from the preacher at Ginny's prompting.
"He did say something about your cousin being invited as well," her mother replied reluctantly, once more frowning. Hillary shook her head. It was time to confront her mother about Michael.
"Ma, it's time you forgave him," Hillary said with a sigh. "Michael's turned over a new leaf. He hardly ever acts sullen or mean anymore and he does his share of the chores now without complaint. His time here on the farm has helped him settle down just like you and Aunt Beth hoped."
Even Hillary's father seemed to be accepting the changes in Michael more easily than her mother. Of course, he didn't know that Michael was responsible for the pictures that upset him so much.
"But he..." her mother began.
"Ma, I know what he did," Hillary interjected. After all, she was the target of the pictures. "If I can forgive him, why can't you?"
"I'll try," her mother sighed, and then changed the subject by asking, "Are you sure you won't come?"
"It's still early," Hillary waffled. "I'll tell you what. Why don't Heidi, Michael and I come by later for dinner?"
"That sounds fair," her mother replied. "We'll see you around five."
"Okay," Hillary agreed.
"Let's hope your sister and Michael turn up before then," her mother grumbled.
"I'm sure they will," Hillary replied as her mother left the bedroom.
Hillary smiled to herself. Heidi was spending every free minute with Michael. He was leaving in a week and a half.
'The little slut can't get enough of our hunk of a cousin!' she thought, her smile turning into a grin. 'Not that he's complaining.'
She picked up her book and tried to continue reading, but she couldn't focus on the page. She kept thinking about what Heidi and Michael were probably doing.
"Oh well," she said to herself with a shrug. "I guess I should go find them and let them know about our dinner plans."
Hillary left the house and made her way toward the cabin where Michael was staying. She wasn't surprised to hear the shower on. It was one of Michael and Heidi's favorite places. Hillary was about to walk in when she grinned to herself and decided to peek in on them instead.
She quickly found the same crack where she and Heidi first starting spying on Michael. She peeked through the hole and her grin grew wider. Hillary saw Heidi on her knees in front of Michael working his rather large cock. Michael held her head with both of hands. The day was supposed to be hot, but it was still early enough for the shower to be steamy. The vapor quickly dissipated as always.
Hillary watched for a while in silence feeling her excitement grow. She bit her lower lip as she tried to decide what to do.
"Heidi, I'm getting close!" Michael cried suddenly. That decided Hillary. It wouldn't be fair to interrupt her cousin and sister just then. So instead, she unbuttoned her pants and slipped one hand past the waistband of her panties.
Her eyes roved over both her cousin's and sister's bodies as Michael grunted and let loose a stream of cum in Heidi's mouth. The sight of her sister drinking Michael's cum had Hillary so wet that she started working two finger in and out of herself almost without realizing it.
'Some summer!' she thought to herself. 'I've certainly changed!' Hillary fought back a giggle.
"My turn!" Heidi said when Michael recovered. "Let go inside and get comfortable."
"Not yet," Michael replied, reaching for Heidi. Hillary watched as Michael grabbed her sister and somehow flipped her over so that he was holding her upside-down with her hips situated so that he had full access to her pussy.
"Michael! What are you doing?" Heidi cried nervously as she grabbed his legs.
"Just what you asked me to," Michael replied, leaning forward and driving his tongue into Hillary's sister's pussy. Heidi moaned.
'Wow! Cousin Michael is pretty strong,' Hillary thought. She watched as her sister quickly forgot about the oddity of her position and started enjoying the feel of Michael's tongue. Hillary decided she wanted Michael to do the same to her, but not in the shower! It looked too dangerous with the slippery floor.
Heidi eventually grew comfortable enough to reach out, grab hold of Michael cock and use her tongue to tease the head. Michael groaned into Heidi's pussy, which made her gasp out. Hillary watched as her and her twin's orgasms grew near.
'I've gone from a relatively innocent girl of limited experience with a couple of boys to a bisexual who enjoys incest and group sex! Hell! It pretty obvious that I'm into voyeurism as well!' Hillary thought as her sister cried out and came. Michael buried his face in Heidi pussy, obviously enjoying the taste.
"Heidi, it's time," Michael said as he placed Heidi right side up on the floor. "I can't wait any longer!" Hillary saw the stiffness of her cousin's large cock and smiled. Heidi was in for one hell of a ride!
"Finally!" Heidi grinned.
"I'm ready to go inside now," Michael smiled.
"Well, I'm not," Heidi said, placing her hands around her cousin's neck and kissing him. Michael returned the kiss wholeheartedly. Heidi lifted and wrapped one leg around Michael's waist. He took the hint and grabbed hold of her thigh. Heidi lifted the other leg as soon as he had a firm grip. Hillary couldn't see when Michael's cock pushed in, but she had no problem seeing Heidi's reaction.
"Oh yes!" her sister cried as she held onto to Michael's shoulders. Michael held Heidi by her ass and thighs, once again holding her off the ground. "Michael you are so strong!"
