Percy x Thalia:
Percy was on his way to the Zeus cabin, not to see his buddy Jason who was currently out with Piper, but to see his cousin Thalia. The hunt arrived just hours ago and Artemis had told him that Thalia was in her old cabin. He wanted to see her, it had been months since they saw each other the last time. He was lost in his thoughts as he arrived at the Zeus cabin and opened the door without knocking, finding his cousin in a quite revealing state.
Thalia laid naked on her bed, one hand kneaded her boobs the other one forced a purple vibrator in and out of her mouth. She had her legs spread, leaving her wet and obviously needy pussy in plain sight for Percy, who couldn't help but stare. The only sounds in the cabin where the slurping noise the girl made as she sucked the toy and her moaning as she played with her boobs.
"Thalia?" the black-haired boy said out loud, making the girl on the bed jump in surprise and open her eyes. "Percy!" she yelled out, shocked that he had caught her like this but didn't cover her nudity. Instead, she started to eye Percy - or to be more exact, his groin. The young son of Poseidon noticed where she was starring and looked down to see his shorts already forming a slight tent. "I'm needy! Please, come here and help me out. I know you want it." Thalia said seductive. "But what about the hunters? What about your oath?" Percy asked. The naked girl sighed and said "Artemis doesn't know, but when I joined the hunt… Well, I wasn't a virgin anymore. It doesn't change anything if we have sex now. Besides, no one needs to know. Right?".
In Percy's mind these were very convincing arguments, so he shook himself out of his stupor and started his way towards the naked girl. A big grin on his face he said "I'm in." and started to strip out of his clothes while Thalia eyed him hungrily. As he pulled down his shorts his cock sprung free, ready to fuck the demigoddess in front of him. He got on the bed and crawled towards Thalia's spread legs.
The girl knew they would do it without any foreplay or teasing, Percy was fully erected, ready and her cunt was already leaking from arousal, what would make it easy for him to penetrate her. Percy lined his dick up with her entrance and before Thalia knew what happened he already was balls deep inside of her, making her scream in surprise. The black-haired boy started to slide his dick back and forth at a steady pace, but the daughter of Zeus wanted more - "Faster… Fuck me harder!" she breathed out - and that he did.
Percy started to thrust forward, shoving his hard cock as deep into her needy pussy as possible. It didn't take the demigod long and Thalia reached her climax, but Percy wasn't ready to give her his precious cum yet. After the girl got down from her high, he pulled back and his dick slipped out of her. She whined but stopped as soon as he heard him say "Get on your hands and knees!" in a commanding voice that didn't allow contradiction. The daughter of Zeus did as she was told and as soon as she was in position, Percy took her from behind with even more force than before. She screamed out in pleasure and even a bit of pain, she never had a man dominate her like this - but she definitely loved it! The black-haired boy groaned as he slammed his dick into Thalia's warm and wet pussy. With every thrust his firm balls slapped against her bare skin, making a load smacking sound. The smacking and groaning were accompanied by loud and breathless moans from the daughter of Zeus. Soon the demigoddess couldn't hold herself together any longer and screamed loudly while having yet another orgasm. This time Percy reached his climax too and came inside of Thalia's tight cunt.
He could have done another round but noticed that the girl he'd fucked had passed out. He smiled at her posture - her arms, which had supported her body to stay upright, had lost their strength - her head was on the mattress, but her ass was still in the air due to Percy being still embedded deep into her vagina.
He pulled his cock out of the unconscious girl and watched how his cum started to leak out of her used, red and slightly swollen cunt. The boy didn't want to waste it like that and grabbed the purple vibrator Thalia had used before he arrived -he pushed the toy inside the entrance between her legs to seal her pussy and turned the toy on. He heard a quiet hum and smiled at the thought of the girl in front of him, reaching orgasm after orgasm while being unconscious. She may be fucked senseless but that doesn't mean that her body can't experience further orgasms.
Satisfied with his work he got dressed and left the cabin.
