Rich was excited when his parents told him that they were all going on a Caribbean Cruise, but was disappointed to find out that the only other people that would be on the cruise were his Uncle Jack, Aunt Jane, and his cousin Jessica Lyn.
He didn't expect it to be much fun, and wasn't too happy waking up at six in the morning the day of the trip to get to the ship. Shortly after arriving they boarded the ship and each got situated in their own rooms. Rich unpacked ready for his two week trip to Hell.
He came on deck as the ship set sail and noticed Jessica Lyn lying out in her bikini. He had never realized how nice of a body she had until now; they had never gotten along all that well, so they hadn't seen in each other in almost two years...
The day went by without much event and Rich was soon left in his room to fall to sleep. It was then that the image of Jess returned to his mind. He couldn't believe the thoughts he was thinking about her, she was after all his cousin. He tried to keep the thoughts from his mind, but he couldn't help picturing her small but well sized breasts, and perfectly rounded ass in her bikini.
He knew it was wrong, but he also knew if he didn't take care of it he would not be getting much sleep. He pulled a sock out his suitcase and wrapped it around his dick with thoughts of Jess filling his mind. He stroked himself slowing picking up speed as his orgasm built, faster and faster...
He was frozen by a knock at his door. He couldn't think, speak, or move before the door opened and his sister Brook entered the room. She didn't notice what was going on at first, but soon she realized and she just stared at Rich in shock.
Rich didn't know what to say as Brook just stood there staring at him. Finally he managed to say, "Close the door."
Brook closed the door, but never took her eyes off of the sock that covered him, she had never seen a penis before, not even covered by a sock. She knew her brother masturbated, she had heard him occasionally but never had she walked in on him.
"Stop staring at me," Rich said.
"I can't," was Brook's response, "Can I...can I, see it?"
Rich was now shocked, "No, just get out of my room, and don't mention this to anyone."
Brook felt embarrassed for even asking and quickly turned away, opened the door and left the room. Rich was now set, no longer horny, and slightly embarrassed, he quickly dozed off to sleep.
Brook returned to him with thought of what she had just seen running through her mind. It had been a long time since she had felt this type of sensation between her legs. In her eighteen years she had only felt the need to masturbate twice. She didn't want to use her fingers, so she leaned up against the side of her bed and started to hump and grind against it.
It felt good, she had been long over due for an orgasm, the thought of Rich stroking himself made her hot, and she was rushing towards her climax. She leaned back off of the bed and thrust her fingers into her shorts, madly fingering her clit. She starting moaning, loud enough that she must have been heard, but at this point she didn't care. Finally she felt her orgasm rush through her and she came hard against her fingers. Savoring every second of the amazing feeling.
Three Days Later...
Nothing exciting had happened, Rich had spent most of his time in his room. He only ventured out for the chance of seeing Jess in her bikini again, but so far he had been out of luck.
Today was the day they would go in three separate small boats and travel off on their own. Jack and Jane wanted to go alone together and Rich's parents went with Brook, leaving Jess and Rich to venture off together. This was the best news of the trip so far for rich.
When they set off the sky was clear and it was forecasted to be a beautiful day. Jess wore a tank top of her bikini top, and nothing of the bottoms. Rich wore a t-shirt and his swimming trunks. Jess just lay out in the small boat for the start of the trip enjoying the sun, but soon felt her legs start to burn.
"Rich can you put some lotion on my legs?" Jess asked.
"Yeah sure," Rich replied without hesitation.
"Thanks, can you do my back too?" Jess asked as she removed her tank top.
