Tracy & Dad – Part Three

Tracy woke up early on the first full day at the cabin. She rolled over and unplugged her phone that was charging on the nightstand. She spent the next twenty minutes answering texts that had come in while she slept and going through her social accounts. Finally hunger got her out of bed. She threw on one of her dad’s old t-shirts that looked like a short dress on her small frame. She didn’t think anyone else was up so she would have to make herself breakfast. As she left her room she thought it wouldn’t hurt to see if the twins were up and if so she would offer to make them breakfast. It would be a nice gesture and it would make her dad happy.

She was not too far down the hall when she heard giggling. So the twins were up. As she was about to knock on the partially open door she looked through the opening and saw the old dresser across the room and her hand stopped. The dresser had a large mirror attached to it and in the reflection Tracy could see the twins. Cassie was laying on her bed only wearing a small pink t-shirt and between her legs was Chris’s head. He was laying on his stomach in just his underwear. Tracy lowered her hand and just watched.

Cassie had both her hands on her brother’s head and a big smile on her face. Chris’s head was moving up and down as he licked her vagina. Tracy could tell he didn’t really know what he was doing but Cassie seemed to be enjoying it. After about a minute Chris raised his head and asked, “So? How does it feel?”

“Feels weird, but also good,” was Cassie’s reply.

“Well Mom really liked it when John was doing it to her last night,” Chris said.

Tracy was startled to hear that. Had the twins seen her with her dad and Nicole last night? They must have.

“Those sneaky little shits,” she thought to herself but smiled. She had spied on her Dad and Nicole a few times so she couldn’t really fault them for it. Plus she was spying on them now so it they were even.

“You want some more?” Chris asked Cassie.

“No. Lets just do it like we usually do.”

Tracy watched from the doorway as Chris got up from the bed and pulled off his underwear exposing his hard penis. He got back on the bed and raised his sisters legs putting her ankles on his shoulders and then used his hand to guide his penis to her moist little slit. The head of his penis pressed against her until it finally slowly sank into her. He gently pushed until he was buried fully in her.

“Ok. Wait for a sec,” she told him.

“I know,” he said and just waited there with her legs on his shoulders and his hands holding her thighs.

As they waited Tracy’s hand reached down and she rubbed her pussy through her t-shirt.

Finally Cassie said, “Ok. You can go now.”

And with that Chris started to fuck her. Not fast at first but the pace started to increase as he continued. Tracy noticed that he never stopped looking at his penis going in and out of his sister. Even when she said to him, “That feels good.”

He replied, “I know,” and just kept watching himself slide into her.

Tracy was surprised to see Cassie start playing with her clit as her brother fucked her.
