Dominique! He sprinted to his cabin to find his sister. She owed him a favor, and this could be it. He practically flew through the door and pinned Dominique to her bed.
"What the hell Percy!" she yelled.
He kissed her rubbing his tongue on hers. She groaned, knowing he was horney again.
"Percy! Stop it, go do this with Annabeth!" she yelled.
"She's -kiss- in -kiss- archery!" he said. He pulled off. "Besides you owe me a big favor."
She glared at him pondering over his words.
"Fine! But be gentle"
His hands flew to her jeans and pulled them off. He yanked his off too and he ripped off Dominique's shirt and bra.
"That was my favorite shirt!" she complained.
Percy ignored her. He licked her nipples while pumping his fingers in and out her leaking hole. She moaned and squirmed under his weight.
He pulled off her underwear and took out his dick.
"Wait, n-no!" Dominique squealed.
He pushed his dick in her, loving the feeling of her walls clamping down on him. He buried his head into her hair.
"You're so tight! So fucking tight." he groaned and he looked at her face.
His eyes widened as he gazed into her eyes. They were filled with pain and she looked close to tears.
"Oh Crap." Percy said. "I'm so sorry Dominique, I'll make it quick!" he buried his face in between her beck and shoulder so he wouldn't have to look at her.
The next time he exited her, he pushed back in at a quicker pace, forcing a muffled gasp from Dominique as she bit her lip, but her eyes screamed for him to keep going. Softly, he pumped his length into her, occasionally burying himself to the hilt just to watch her face contort with lust. Her hand released his and both of her arms hung around Percy's neck, pulling his chest back down to hers. Her grip only loosened when his free hand traced down her side and across her stomach, where it started to pinch and rub her clit. A shuddering moan echoed into the cool air, louder than the rest.
"Percy, please, stop."
Her voice was merely a whisper as he sped up, steadily fucking his sister into a mess of whimpers and cries. With nothing else to listen to in the cabin, each slap of their flesh or wet squelch was deafening. Dominique's back arched at a painful angle as she tightened drastically around him, and a choked moan caught in her throat as she went rigid, twisting herself as she came. Percy nearly groaned from how hard she was biting his neck, but the moment passed, and she slowly pushed herself up, much to his confusion.
He grazed a spot in her and her pussy clenched. He pounded harder into her, his thrusts becoming more and more uneven as he felt his orgasm build layer after layer.
"Yes, yes, oh fuck yes!" he yelled pumping into her and he shot his seed into her in climax. He flopped to his side so he wouldn't crush her pulling out. Dominique was unconscious on her bed. Percy got a rag and cleaned her and the bed up and fell asleep beside her murmuring thank you.
