Do whatever the girls suggest.

“We’ll start by, umm, kissing then,” Annabeth suggests, sitting at the foot of his bed. “Come here, Percy.”

Both Percy and Thalia look at each other. “Perhaps I should start with Thalia to get her in the mood?”

Thalia looks away, but she doesn’t protest.

Annabeth nods. “Then sit in the middle. We can take turns kissing you and see where it leads. We might not like it much.”

Percy didn’t believe Annabeth’s words, and neither did she. Thalia stood there feeling awkward, but she sat beside Percy once he got into his spot next to his girlfriend.

The half-bloods studied each other, Percy and Thalia. Under the sea glow of his cabin, their features were highlighted. The faint scars from Percy, the now pronounced freckles on Thalia’s face. His green eyes were dull when compared to vivid blue ones now. Her breath is warm and minty, hands tender and careful. She closed her eyes when he leaned in to kiss her for the first time… her first intimate kiss ever.

The soft clicking of their tongues began to bleed into the room. Percy had to do most of the guiding. His tongue lathered against Thalia’s as she stiffened her back and held her breath. “You can breathe,” he commented. Thalia opened her eyes but saw his were still closed.

“I know,” she said, breathing. “Just shut up.”

Percy’s hand rode up her torso. He felt the tension in her body melt slightly, but she also started to tremble. Before Percy could become too handy with Zeus’s daughter, Athena's child begins rubbing his side to announce her entry silently. She was only slightly suggestive at first but was soon trailing down to his pants, where she applied generous pressure around his groin area, making his cock rock hard beneath the cotton jail cell, which was his underwear.

Thalia started to relax, letting Percy’s tongue poke and prod hers as he willed. She thought he tasted a little sweet, perhaps with a slight bitterness of something he had eaten before this interaction. Eventually, however, she becomes more confident and pokes his tongue back. Percy breaks the kiss and laughs slightly before he grunts — Annabeth had made herself known in his pants. A bulge, the size of Mount Tamalpais, was growing by the minute.

A curse in ancient Greek parted Percy’s lips when he saw Annabeth’s hands on his lap. They were practically jerking him through the denim of his jeans. “I’m still here,” Thalia said, annoyed that Annabeth had taken the spotlight.

He glanced over and saw her deep blue eyes under a veil of sexual frustration. “So am I,” Annabeth says on the other end, not yet wanting to be ignored.

“Thalia,” Percy said, “take over for Annabeth.”

Thalia stammered something in protest but stopped herself when she heard the soft intimate clicking of tongues and horny moans come from both of the half-bloods.

Percy felt Thalia's fingers ride along with his imprinted cock with careful intent. Even though he and Annabeth had just started their intimacy record as a couple, he could tell Annabeth was far more comfortable with his body than Thalia was.

He breaks the kiss with Annabeth and looks at her. “Sorry. I have to get it out.”

Thalia retracts her hand. Annabeth looks at her and nods. “You should do it.”

“Me? Why me?”

“Because it’s your first time,” Annabeth was so matter of the fact that there was no argument. “It’s not going to hurt you.”

Thalia gulped. She didn’t look like she believed Annabeth but proceeded to fumble with Percy’s belt buckle and zipper anyway. She was not going to let Annabeth beat her in something, even if she wasn’t supposed to do it.

Percy’s cock sprung out and slapped Thalia’s face. Her warm freckled cheek had a faint streak of precum across it now. She gripped his spear and began to tug on it lightly, careful at first, but quickly realized she needed to be less frightful of his penis, no matter how big it had been to her.

“You have to do more than just that,” Annabeth said. “Spit on him, Thalia.”

“S-spit?”

“Or lick it. Or put your lips around it. Something to get his dick wet.” Annabeth said.

Gingerly, Thalia stuck her fingers into the small patch of precum Percy had produced so far and used it as lube. Annabeth, with her boyfriend, watched Thalia improvise instead of doing what was instructed. It’s kind of lewd but incredibly enticing. “Damn,” Percy said.

Annabeth focused on Percy again, kissing him with tongue and emotion. Driven by lust and a little bit of jealousy, she pressed her lips into his and moaned, hoping to keep more of his attention on her rather than the girl on her knees. Annabeth’s tan face obscured his vision, but it didn’t matter now; he was counting on his sense of feeling.

Percy’s mind span while his tongue tangled with Annabeth's. Thalia was winning his attention, but only because she jerked him off at a steady rate and kept teasing his tip, rubbing his precum along his shaft while she motioned her first up and down its length. Eventually, another hand joins Thalia’s handjob; it feels different, so he figures two girls are pleasuring his demigod cock.

“You’re rock solid,” Thalia announced with amusement. “It’s like I’m holding my spear again.”

Annabeth broke the kiss, gazed down at his “spear,” and smiled tightly. “Well, what do you want to do next?”

Percy was about to answer, but he realized she was regarding Thalia again. He wasn’t going to complain— they do whatever they want now.
