"Wait for me outside." Amy ordered. "I'm going to get changed." Jeff watched Amy's naked ass wiggle as she walked away. He threw on his shorts only, and went out the sliding back door.
Jeff's cock twitched and his jaw dropped when Amy emerged from the house a few moments later. She was wearing the tiniest, skimpiest pink bikini he had ever seen! The top was just a couple of straps, with barely enough material to hide her nipples! From the front, the bottom looked like it was barely containing her pussy! She had a big smile on her face, but he didn't really notice her face at first.
She stepped out onto the deck and turned around, showing off the back. She may as well have been naked! His baby sister's skinny ass was clear of all cover, the string of the bikini was hidden somewhere between her white cheeks. His cock was suddenly straining hard against his shorts, and his breathing had deepened dramatically. He was speechless. Amy turned back around.
"So did you fuck Bonnie outside at all?" she asked, erotically. Her dark eyes were looking at him challengingly, as if she expected the answer to be 'no'. His eyes could not help but wander down to her fantastic tits, and her clearly revealed cleavage.
"Yes." He said, finding his voice. Amy looked, surprised, angry, and disappointed. She brought her hands up to her bikini top and pulled it down and on the outside of her breasts. Her pink areolas were revealed, and her nipples were very erect. Jeff looked around, nervously.
"Don't worry." She said, "They aren't home." She pointed behind him. "And they..." she pointed behind her, "can't really see over here. And the people behind us are too far away." His eyes were locked on his sister's tits. She smiled, and sat down on a lawn chair. She placed her feet up on the edge of the chair, curling her toes over the edge and opening her long legs. Now his eyes were locked on her crotch. She slowly brought her hand down between her thighs, and he watched as her fingers slowly pulled the side of her bikini bottom over. Gradually, the curls of her bush came into view. Followed soon after by her pink, swollen pussy lips.
"Brother?" she asked, pouting, "Will you eat my pussy?"
Jeff felt weak in the knees, almost falling over. His cock almost ripped through his shorts! Amy's puckered cunt lips were pressed tightly together, glistening with moisture. He stepped closer to her, falling to his knees before her.
As he bent his head between her thighs, he could smell the strong scent of her pussy. He kissed her quivering lips. "Ohhh..." she sighed, tingles shooting up her body. Still holding her bikini bottoms to one side with one hand, her other hand brushed his hair back, sliding behind his head and holding his face in her pussy.
He sucked her sensitive lips into his mouth, causing her to gasp again as he released her skin. He slid his hands under her near naked ass, his tongue darting out and slowly licking from the bottom of her slit up to the top. Her taste, his sister's taste, was incredibly strong on his tongue. His hands squeezed her skinny ass tightly as his tongue teased over her clitoris. She caught her breath again as tingles shot up her body. He slid his tongue into her tunnel. Now he could really taste her! He twirled his tongue around the inside of Amy's vagina, gathering her delicious juices as she squirmed above him. He sucked hard on her pussy, sucking her flowing liquids into his mouth and drinking her.
"Ohhh..." she moaned, leaning back and closing her eyes. Her fingers stroked his hair as his tongue danced on her slit. Jeff sucked her clit into his mouth and held it there, teasing over it with his tongue. Amy began to writhe her crotch up into her brother's face as he mercilessly lapped at her clitoris. She was moaning softly.
Suddenly, Jeff began to lick her clit as fast as he possible could. His tongue was lashing lightening quick at her tiny button, and she hurtled towards orgasm.
"Ohhhhhh! Ohhhhh fuck!" she breathed. Her entire body grew hot, and she writhed her crotch up into his face as she came violently. Her hand was pushing his face hard into her convulsing pussy as he continued licking at it. Her heart was pounding, she thought it would explode!
Jeff continued to eat her cunt as she rode out her orgasm. Finally, it subsided and Amy pushed his face away. Her face was all flushed and her chest was heaving as she gasped for breath. Her pink pussy lips were parted slightly, quivering invitingly.
"Fuck me, Jeff." She whispered, still recovering. She may be recovering but she still wanted that cock!
Completely forgetting that he was outside in broad daylight, with only a small fence surrounding the deck with the hot tub, Jeff undid the button and zipper on his shorts and they fell to his knees. He had to stand up and crouch, as he wasn't quite tall enough to fuck her on his knees.
Amy eagerly grabbed his rock hard cock in her small hand and aimed it down at her needy treasure. When the head of his penis touched the entrance to her pussy, he could feel the tremendous heat emanating from it. He pushed forward, and the petals of his sister's vagina opened up and allowed him to squeeze inside.
"Ohhhh yesss..." Amy moaned, closing her eyes and arching her head back. She could feel her brother slowly ease his thick penis inside her hungry twat, inch by inch. He continued forcing his dick into her, not stopping until he suddenly found himself completely inside her! He slowly slid out of her, his eyes watching his penis as it pulled her pink lips outward. He saw that her bikini bottoms were rubbing against his shaft a little, they had gradually slipped back over her bush somewhat. He pulled his dick right out of her with an audible 'slurp', and he watched the erotic sight of his little sister's pussy lips closing back together. He grabbed the tiny string of her bikini bottoms and pulled, Amy raised her ass off the chair a little. He slid the tiny things down her long legs and she pulled her feet out of them one by one. He dropped them on the deck, and her feet returned to the edge of the chair.
Jeff stared hungrily at his baby sister's beautiful pussy, and as he crouched over her, he allowed the young girl to grab his pole and aim the mushroom head back at her entrance. She looked down between her legs were his thick, mushroom head pressed against her swollen lips. He pushed forward, sliding into her once again. He entered her warmth in one stroke, and she moaned, closing her eyes. Her hot cunt was tight around him!
