He squeezed her breasts together hard, his cock stabbing into her womb. "Take it little sister! All of it." The tip blasted cum into her, coating her insides with thick, hot seed.
"Is there anything else my little sister wants?" He said, grinding his hips into her. He pulled out and wiped his member across her thighs, getting it hard again.
He rolled over beside her, wedging his cock between her legs as he pulled the covers over them. "Get some rest, you'll be needing it for the morning." He said, putting an arm around her, his hand holding her chest.
She nuzzled her back against him and closed her eyes quickly going to sleep. She made cute little squeaks as she slept and her chest rose and fell in a rythmatic pattern:
When they woke up, he was under her. She was laying across his chest, her legs tangled with his. He ran his hands up her sides, feeling his sister's slender frame.
He flexed his member as she started rubbing it. "I bet you do. But right after I get a piece of that ass." He ran a hand down her side and gripped her thigh.
He got on his knees behind her, putting his hands on her rear. He spread her butt, looking down at her puckered hole. He obliged her wishes, pressing his head against her ring until it went in.
She yipped but then moaned and looked at him, "Oh brother it's so big!" she said and moaned out loud. Her hand slid under herself and began to finger her wet hole as she moaned out his name.
He held her narrow waist as he plowed his length into her ass. He felt her hole contorting around his cock, grabbing and pushing against it as he fucked her.
He rammed his length up her ass, pressing her into the bed. His lips gently kissed and nipped at the back of her neck as he ground his hips against her rear.
He grabbed her by the neck, pulling her into a deep kiss as he started hammering her ass again. He lasted another minuet, holding the kiss the whole time. He finally broke it as he put his arms around her waist, pulling her into him as he made one more hard thrust and came inside her.
She went wide eyed and moaned out, "Fuck oh yes brother fill my ass!" she said and fell on him panting, "May we shower I feel so dirty," she said then winked, "Plus I want the Rick clean so I can suck it all!"
He pulled out, shooting his last couple ropes onto her ass. "Yes. Come on. " He said, rubbing her used butt. He turned on the water and got into the shower, standing under the warm stream.
She followed him down the hall, cum oozing out of her ass and grinned getting in as well. She dropped to her knees as she rinsed off and threw her hair out of her face and wrapped a hand around his cock and began to rub it, "Oh brother is so big!"
He put a hand on her cheek, petting her face as she started rubbing his cock. "And think, you just had the whole thing buried in your little butt." He said, rubbing his length against her face.
