Percy, Annabeth, and Grover were headed towards the lunch hall. As they passed the Zeus cabin, Percy turned around. Annabeth and Grover stopped. "Where are you going?"

Percy pointed to the Zeus cabin. "The lights are still on in there. I'm going go see if Thalia knows it's dinnertime. Go ahead without me."

"Okay." Grover and Annabeth both continued to the lunch hall.

Percy headed over to the cabin. As he got closer, he could see that the door was ajar. She had likely kept it open to allow the cabin to air-out a bit. It was late in spring and summer was just around the corner, so Percy couldn't blame her for that. Most people were forced to wear as little clothes as possible thanks to the heat. Boys went around shirtless and girls were practically wearing bikinis. Earlier today, he himself had to change his shirt because it had gotten so sweaty. When Percy got to the cabin he made sure to take careful steps. This was part of a game he was playing. He would try to see how close he could get to people without them noticing. He was getting pretty good at it. He got to the door of the cabin without making a single sound. He peaked in through the crack. He looked around the room. It was mostly empty. Percy could relate. Having one of the Big Three as your parent meant that you didn't have many siblings. Percy eventually found Thalia's bed. On it he saw a black bathrobe laying there. He thought this was odd, but figured she had probably just got out of the shower.

He looked around and finally saw Thalia standing in the corner of the cabin. When he saw Thalia, his heart skipped a beat. He had caught Thalia as she was in the middle of changing her clothes. They were on the floor and Percy could see Thalia standing there in her underwear. Her very sexy underwear. She was wearing a lacy leopard print pair of bra and panties. The bra seemed to be a push-up, as her cleavage was clearly inflated. Percy got a good look of that cleavage as Thalia bent over to pick something off the floor. She turned around and Percy realized that she was wearing a thong. Percy's heart was racing. He was completely mesmerized by the sight of Thalia's scantily clad body. He was so distracted that he almost forgot why he was here. He realized that Thalia might spot him any second now and get suspicious. He wondered if he could just walk away, but then Annabeth and Grover might get curious if he didn't come back with Thalia. He thought about it for a while and then came up with an idea. He lightly knocked on the door. Thalia jumped. "Who's there?"

Percy was practically snickering. "It's me Percy. I just wanted to tell you it's dinnertime."

"Right." Thalia rushed to get her robe on. "Thanks."

"No problem," said Percy. "It was my pleasure."

It was the middle of the night. Percy was tossing and turning in his bed. He had been trying to go to sleep for what seemed like hours. His eyes were heavy and his brain was groggy, but he still couldn't bring himself to go to sleep. Desperate, Percy decide to turn to a tried and true method that always put him to sleep. He was going to masturbate. He took his member in his hand and began squeezing it until he was erect. When it was good and hard, he started rubbing up and down his shaft. His mind began going through a series of fantasies that helped him get off. He decided to go for a new one. One he had been thinking about since dinner.

Percy imagined Thalia sitting at the foot of his bed, wearing her leopard print underwear. She had a wicked smile on her face. She playfully crawled up the bed. "I always wanted to know what it was like to fuck the son of Poseidon."

Percy smiled. "Well here's your chance to find out."

"Oh goodie." Thalia unhooked her bra, allowing Percy to have a good look at her naked breasts. She grabbed them playing with her nipples. "Like what you see?"

"Oh most definitely," said Percy.

"I can see." Thalia pulled back the blankets, exposing his erection. She lowered her head and put her lips around the shaft. She sucked on it, sending Percy's heart right through his chest. Thalia then began bobbing up and down the shaft. Percy moaned, putting his hand in Thalia's hair. He pushed her head down further. He could feel her tongue licking him, massaging his balls. This drove him wild. She gently ran her tongue up and down the shaft. She then lifted her head up.

"What's wrong?" said Percy. "Why'd you stop?"

"I wanted try something new." Thalia then proceeded to put Percy's erection between her cleavage. She squeezed her breasts together. Percy loved the soft, natural feeling of her massive breasts. She rubbed her breasts together and Percy didn't know if he could hold it in anymore. Sure enough, he felt a strange feeling and soon his fingers were wet. He wiped them off against his sheets and put his head on his pillow. He was asleep in no time.
