Chapter IIMark awoke the next morning, as usual with his morning hard-on. He laid there in his bed, thinking about spying on his sister taking her shower last night.

He was wearing a loose pair of old gym shorts as he walked down the hall towards the bathroom. He was so glad their parents were going to be away another two weeks in Europe on vacation. As he walked, he was thinking of how he was going to seduce his sister so she would have sex with him.As he turned the corner into the bathroom, there stood Kayla at the sink, washing her face. His cock began to throb as she was wearing a thin white t-shirt that he could clearly make out the outlines of her large breasts. Her nipples were poking out as she leaned forward over the sink. She was absolutely stunning in every aspect.As his eyes dropped lower, he couldn’t believe it as she was wearing only a pair of sheer black lace panties that covered about half of her sexy butt cheeks. The panties were sheer enough that he clearly could see each perfect globe of butt flesh and the gorgeous crack up the middle. Pre-cum oozed from his swollen cock head.“Good morning Kay.” He said as he moved behind her towards the toilet trying to hide his massive hard-on.“Are you almost done? I have to pee pretty bad.” He asked her.“Morning Mark. I’ll be a few minutes yet. If you really have to go that bad, go ahead. I won’t watch.” She replied back as her pussy was tingling as she hoped he would go for it.Mark stood there for a second, holding his rock solid cock inside his shorts and was istanbul travesti trying to decide what to do. The toilet was right next to the sink so it was nearly impossible for him to go without Kayla seeing his throbbing cock in the mirror.

He was covering his hard thick cock with his hands as he slowly aimed it towards the bowl.

Seconds felt like minutes as he stood there pointing his erect cock toward the toilet.Kayla couldn’t believe her brother actually pulled his cock out right next to her as she continued washing her face. What she thought Mark didn’t realize was that she could look at his beautiful cock right there in the mirror. Her juices were soaking her panties as she examined her brother’s gorgeous cock in the mirror. She watched as his hand slowly ran up and down the full length of his blood engorged member.She couldn’t believe how huge the head of his cock was, all purple and thick looking. She wondered how, if given the chance, could any girl fit it in their mouth or if her pussy would stretch enough to allow it inside her. She studied the thick veins running down the length of his shaft. Her nipples were now fully erect and puffy as her breathing was getting heavier by the second.Kayla was so turned on and aroused, she would soon rape her older brother unless she got out of there. For some reason, she insisted he was going to be istanbul travestileri the one to make the first move. Reaching for the towel, she dried off her face and threw the towel at Mark’s face.

Her panties were completely soaked.As she was leaving the bathroom, she said, “You better take care of that thing before it explodes.”Mark knew Kayla was checking out his cock but he couldn’t help himself. He wanted to pull her panties down, bend her over the sink and slide all eight inches deep inside his sexy sister’s tight pussy. What he didn’t know was that was the same thing she was thinking. Unfortunately, neither of them was brave enough to cross that incestuous line.He knew his sister was aroused as her erect nipples were clearly visible through her thin t-shirt. After she threw her towel in his face, he quickly pulled it away just in time to see her gorgeous sweet panty clad ass exiting the bathroom. His cock was so fucking hard. He had to jerk off right then.Without closing the door, he moved to the sink and grabbed the wet bar of soap. He got some soap on his hand and in about five hard strokes, shot a huge load of his hot cum into the sink. What he didn’t realize was that Kayla was standing in the hall, her hand in her panties with three fingers deep inside her pussy as her thumb strummed her throbbing clit.They were once again only a few feet apart as both of them shuddered and trembled as their bodies swept through intense waves of pleasure as their orgasms consumed their bodies.

His cock was once again getting hard. All he had to do was think about his sexy little sister and he was immediately getting hard.
