"Richie," Susan said, turning to her brother, "do you know Aunt Martha's address?"
"Not offhand," the boy answered. "Why?"
"I want to send her a thank-you note for the birthday present she sent me."
"You can probably find it in Mom's address book," he answered.
"Where does she keep it?"
"I think it's in the top drawer of her bedside table."
The pretty girl hurried up to her mother's room. Opening the drawer of the nightstand, she was shocked to see a big picture of a woman's cunt on the cover of a magazine. Turning the pages with trembling fingers, she was completely stunned by the unbelievable photographs inside. There were pictures of men with huge hard cocks, and because of the girl's innocence, she hadn't dreamed that a man's cock could get anywhere near that big. She'd always assumed they were about the size of a finger. These pages were followed with photographs of beautiful women sucking on men's pricks as well as men licking, pussies. She was both shocked and fascinated by a picture of a lovely naked girl stroking a man's cock that was shooting thick white cream all over her face and tits. Another photo showed a woman catching a stream of hot cock-juice in her mouth.
As she sat on the edge of the bed leafing through the magazine, she began to get hot and wet between her legs. As filthy as the pictures were, they made her cunt tingle like crazy. Wondering why her mother would have such trash around, she decided to take the magazine downstairs and show it to her big brother.
"Look what I found in Mom's drawer," Susan said, handing the magazine to the boy as she sat down next to him on the couch.
When he started turning the pages, Richie was just as stunned as his sister had been. As he excitedly stared at the deliciously naked girls sucking on cocks, his own prick suddenly exploded into an instant hard-on.
"Can you believe this?" gasped Susan as her brother avidly studied the photographs. "Why would Mother have such a dirty book?"
"It beats me," he grinned. "But these are sure some wild pictures."
"Is a man's thing really that big?" asked Susan.
"Some are," was the boy's answer.
"Then how do you get your pants on over it?" was her innocent question.
"It's not usually that big," he tried to explain. "A prick is soft and limp until a guy gets a hard-on."
"What's a hard-on?"
"W-well," he stammered, "a man's thing swells up when he gets excited."
"Do these pictures excite you?" asked Susan, aware of the effect they were having on her tingling pussy.
"Yeah," he grinned. "They sure do."
"Do you have a hard-on? Let me feel it," she giggled, reaching over and grasping his crotch.
"What the hell are you doing?" gasped Richie, shocked that his sister would do such a thing.
"I wanta feel it," she whispered excitedly as the big hard bulge twitched and throbbed against the palm of her hand.
"Knock it off!" panted Richie. "It's not nice to mess around with your own brother."
"But I'm not messin' around," she argued. "I just wanta see what it looks like."
"God, Sis," he gasped. "Dad would kill me if he found out I let you touch my prick."
"He won't know unless you tell him," argued Susan. "Please let me see it."
"Okay," he finally agreed. "But don't mess around with it."
Seizing the tab of his zipper, Susan quickly lowered it and eagerly reached inside for his cock. Because her brother wasn't wearing shorts under his jeans, her hand instantly felt his big sausage-shaped prick, and it was deliciously hot and hard. The pretty girl's body was trembling with excitement as she eased his cock out of his open fly.
Letting her fingers caress and explore his throbbing meat, Susan couldn't get over how pleasant it was to touch the warm and silky flesh of his lust-bloated boner.
"Richie," she whispered.
"What?"
"Take off your jeans so I can see your balls, too."
"Don't be silly," he snapped. "This has already gone too far."
"Please," his sister urged him. "Just let me look at them for a minute."
"Okay," he finally agreed. "Just a quick peek and then we're gonna knack this shit off."
When he removed his jeans, Susan stared intently at his naked crotch. Just below the base of his stiff-standing cock, she could see his big lusty balls dangling between his legs. She was strangely fascinated by the crinkly skin of his hairy nut-sac. With Richie standing directly in front of her, she reached out and gently cupped his lust-swollen balls in her palm. Then, casing her hand farther back between his legs, she found the puckered ring of his asshole and began mischievously tickling it with the tip of her finger.
"Jesus, Sis!" he gasped, quickly sitting down beside her. "We better stop this shit or I'll come."
"I'd like that," she giggled, recalling the picture of a cock shooting cum all over the pretty girl.
"Would you really?" asked Richie as his sister's cool fingers closed around his hard shaft.
"Sure," she grinned. "I'd like to make your prick squirt like the one in the picture."
Richie's entire body began trembling when Susan started sliding his foreskin up and down over his sensitive cockhead.
"Promise not to tell anyone," gasped the boy, suddenly thinking how good it would feel to be jacked off by his cute sister.
"I promise."
"Then can I play with your tits while you're messin' with my prick?" he asked excitedly.
"Sure," beamed Susan, quickly unbuttoning her blouse and removing it.
"Jesus, Sis!" gasped the boy as he stared at her firm tits with the big juicy nipples sprouting out from them. "You're really growing up."
"I know," she giggled, looking excitedly down at the luscious length of cock she was holding.
Skimming her fingers up and down his throbbing prick, she was thrilled by the feel of his thick foreskin sliding over the purple flesh of his swollen cockhead. Anxious to see him shoot off like the man in the picture, she began moving her hand a little faster. With his dick throbbing violently in the erotic grasp of her fingers, she could feel it lurching and swelling even bigger with every naughty stroke.
As she continued stroking her brother's wonderful big cock, she was acutely aware of his hand sliding up over her bare tit until his fingers found her erect nipple. She could feel the sensitive bud sprouting deliciously harder as he rolled it between his finger and thumb. "Oh, God, honey," she giggled, still sucking his thick cock. "That feels so neat."
Then, holding her breath, Susan watched her handsome brother's mouth move down toward her naked boob until she felt his warm lips slip over her quivering nipple.
"Ooooooooh, darling," she whimpered, the fingers of her free hand curling into his thick hair, pressing his mouth down tighter over her naked tit. "That drives me wild."
Finally lifting his face from her tit, Richie passionately kissed his sister on the lips for the first time in his life. He could feel a shiver racing through her sensuous body as his tongue moved like liquid fire between her teeth. Susan had never been kissed like this before, but she quickly answered it with the tip of her own pink tongue. Soon they were both wantonly sucking on each other's tongues, their bodies squirming against each other in a frenzied passion.
Lowering his hand as their lips remained welded together in lust, Richie slipped it up under the hem of her skirt. Almost out of his mind from the way his sister was stroking his hard naked meat, he began slowly moving his hand up between her soft bare thighs.
Feeling his fingers moving ever closer to her pussy, the pretty girl's legs began opening and closing, involuntarily. She could, feel her asscheeks clenching as she excitedly squirmed her hot ass down into the cushion. Still lustily stroking his stiff dick as his hand crept closer and closer to her wildly aroused cunt, she could feel the hot dampness of her cunt juices oozing out into the crotch of her panties.
