Jason x Thalia:
Thalia was visiting Camp Halfblood and had just spend two hours of training with her favorite cousin Percy. He was shirtless and his hard abdominal muscles glistened with sweat, making her horny. She wanted to have a little fun with him again, but he had to train the younger kids today. That left Thalia no choice but to get rid of the problem on her own.
The black-haired girl made her way towards the Zeus cabin, already feeling how her drenched panties stuck to her wet, hot pussy. As soon as she was in her cabin, she ripped off her clothes, leaned back against the closed door, spread her legs slightly, pushed two fingers inside her pussy and started to pump them in and out. She had closed her eyes the moment she stepped into the cabin, too overwhelmed by her own lust to even look around the cabin once. If she had done so, she would have seen her brother Jason on his bed, his right hand buried inside his shorts. Jason looked a bit shocked at Thalia, who still hadn't noticed that she was not alone in the cabin. He clearly saw her arousal between her legs and knew both were in need of a fuck to relieve them of their lust - but could he fuck his own sister? Looking down to his erection, which was still partly hidden by his shorts, he decided he could. Jason got up quietly, slipped out of his shorts and underwear and stood naked in the middle of the room. His cock, which was only semi-hard before was now fully erected, thanks to the sight of his naked and needy sister.
"Need some help?" he asked loudly to draw Thalia's attention to himself. The girl opened her eyes and looked at the son of Jupiter in shock. She just wanted to cover herself as she noticed his nakedness and the big hard cock between his legs. Changing her mind, she said "Yes. I'm dearly in need of a good fuck!" without hesitation. Jason grinned and overcame the distance between them with a couple of fast steps. The girl still pressed her back against the door as her brother grabbed her ass and picked her up. Thalia gasped once in surprise as she lost contact to the floor and again, just a second later, as she felt how her brother lowered her on his hard dick. Her pussy was almost dripping with arousal, making it easy for him to enter her. As soon as she was in position, Jason started to pound into her and fucked her against the wall, or rather against the door, in a standing position.
His fast and hard thrusts penetrated her deeply and caused her boobs to bounce every time he pushed up-/forwards. "Gods, your tight." Jason groaned as he pushed into her again and again. With every move he felt his dick move inside Thalia's tight cunt, creating a heavenly friction. Added to the feeling of her tight walls around him was the sensation of his sensitive balls slapping against her ass every time he shoved himself balls deep into her. Thalia already orgasmed once before and was close to reach another peak in unison with Jason. The blonde-haired boy thrusted into the female one last time before spreading his cum inside her warm pussy with a loud groan. Feeling the hot liquid inside her, Thalia reached her climax too and screamed loudly as she heavily came all over Jason's dick.
Both breathed heavily but Jason said "We are not done yet!". He pulled out of his beautiful sister, causing some of his white seed to leak out of her pussy and running down her thighs. He set Thalia on her feet again and took a step back from the door, pulling his sister with him. The son of Jupiter turned the girl around, so that her back was now facing him and bend her upper body down. Thalia placed her palms on the door to support her body and Jason took a moment to appreciate the view. The girl's cunt was red and swollen and a mix of her own pussy juice and his cum made it glisten in the sunlight which shined through one of the windows.
The blonde-haired demigod stepped closer and slapped both ass cheeks the girl willingly hold out for him, making them look red and slinky. He wanted to hear her voice again and decided to slap her pussy, which elicited her a pleasured scream. "Say my name!" he said and slapped her wet cunt again, which caused her to scream his name in joy. He placed the tip of his cock at her entrance but didn't move in, instead he said "Tell me what you want! Tell me how much you need this!" while looking down on her with a grin. Thalia whimpered at the feeling of his tip touching her cunt, teasing it and said "Jason, please fuck me! I'm so horny. Please fuck my needy cunt as fast and hard as you can!".
And that he did.
The roman demigod rammed his hard rod into the black-haired girl before him with powerful and fast thrusts. He used so much force, that Thalia's arms buckled in and she almost crashed against the door, which she used to support her body. She breathed intermittently and screamed louder with every thrust Jason did. The boy himself grunted in effort but enjoyed their fuck immensely. Jason endured for quite a long time, considering the speed he moved, but he couldn't continue forever. "I'm going to fill you with my cum!" he groaned out and heard his sister moan before saying "Oh, yes please. Fill my pussy white with your seed!". Unable to reject her, Jason forced himself as deep between Thalia's legs as possible and injected his creamy cum into her cunt, adding a new load to the one already inside of her. Thalia felt how her brother came inside her pussy and screamed loudly, as she felt another orgasm role over her. Jason pulled back and watched as his semen started to leak out of Thalia's used cunt as soon as his cock left her wet entrance. As the creamy white mixture of his sperm and her pussy juice run down her thighs, Jason wiped it away. He collected the liquid with his hand before wiping it on her clit and pussy.
He lightly slapped her pretty ass a last time - causing Thalia's legs to buckle in, leaving her exhausted on her knees. Satisfied, Jason turned around and made his way towards the bathroom to take a shower and clean himself of all liquids and the smell of damn good sex.
