And now perhaps she could be like a lover to him, too. As soon as he'd walked in the door with a big grin and his suitcases in his hands, Donna had felt a strong sexual attraction.
He'd grown taller and leaner since she'd last seen him, and a new growth of athletic, musculature had given him an appealing physique. Donna found herself considering forbidden desires during the first several days of his visit.
He had turned into a very handsome young man, with soft, curly brown hair and the male version of her family's good looks. Most importantly, the bulge in the crotch of his pants was quite large and promising. Several times Donna caught herself hungrily studying the outline of her young brother's dick.
Roy noticed her looking at Bobby too.
"You keep your God damn hands off of him," he warned her the first night of Bobby's stay. "I mean it, Donna. I don't care how weird this family gets, you're not giving your pussy to any blood relative."
"Oh, for God's sake," Donna had protested. "Fucking my own brother! What kind of a girl do you think I am?"
"I know what kind," Roy had replied gruffly. "Don't play innocent with me. If I catch your mitts on that prick of his I'm going to tan your ass so bad you'll wish you'd been born an orphan."
Donna had muttered an obscenity or two and refused to continue the conversation. But she'd known that there was truth in Roy's accusations, and she decided to suppress her desires. Incest with her brother would be sinful. She had no intention of stooping to such depths to gratify her needs.
But that was before she caught her brother jerking off.
It happened only five days after his arrival, on a sunny, windy weekday afternoon. Donna was vacuuming the living room when she decided impulsively that the rest of her chores could wait for the next day. She was getting tired of housework, and it had been awhile since Bobby and she had enjoyed a good brother and sister talk.
He was upstairs in the guest bedroom reading, she thought. Donna put away the vacuum cleaner and, walked to his room without changing her clothes. All she had on were a pair of slippers and a skimpy house robe that barely covered her pussy. She knew Bobby would be able to see her big, braless tits jiggling under the robe, and more of her naked thighs than some might consider proper, but that didn't matter. Why be shy around her brother?
Bobby's bedroom door was ajar. Donna walked to it happily, smiling as she prepared to ask him if he wouldn't mind socializing with her for the rest of the afternoon. Then she looked through the door and saw what he was doing, and the smile faded from her lips.
Bobby was on his back on the bed, stark naked. Donna had known he had a good figure, but she'd never guessed his muscles would be so tan and hard, or that he would have such a hairy chest.
His dick was standing straight out of his short, curly hairs, as hard as a rock. Donna whimpered almost inaudibly as the heat of lust stabbed suddenly deep inside her cunt. Her little brother had a gigantic hard-on, longer and thicker than Ted's or even Carry's. It was the biggest cock she'd ever seen.
"Ungghhh," Bobby groaned. His cheeks were red, and his expression was contorted obscenely with desire. As Donna watched, his hand raced smoothly up and down his enormous, blood-clogged dick. Rhythmically he massaged its burning stiffness, jacking himself off.
Pre-cum oozed from his swollen, purplish cockhead. His lean thighs quivered, and the bed shook beneath him as he humped his hand. Donna pressed close to the crack in the door and kept watching. She knew it was wrong to be there, that it was sinful to take pleasure in the sight of her brother's cock.
But she'd lost all control over herself. Her nipples tingled with their stiffness, rising to protrude through the sheer fabric of her robe. Donna's hairy pussy grew wetter and hotter every time Bobby stroked his massive cock.
"Unnggghh!" Bobby moaned loudly as he beat off, obviously unmindful of the fact that his sister was with him in the house. "Oh fuck it… so good… umm."
His stroking movements quickened. He arched his back as his over-endowed cock grew even larger in his hand. Abruptly Donna realized that he was about to come, that his creamy load would be wasted as it gushed on his chest and belly.
She couldn't let that happen. The next thing she knew she'd pushed open the door and was standing before her brother's bed, literally panting with lust as she aired hungrily at his twitching, throbbing cock.
"Donna!" Bobby whipped his hand from his pulsing dick and stared at her in shock. "What the fuck are you doing in here?"
Donna moved closer, never taking her eyes from his upthrust prick. It was at least ten inches long and as thick around as a ripe cucumber. What a hunk of meat, she thought, whimpering as her pussy throbbed painfully between her thighs. Never before had she felt so unbearably, irresistibly horny.
"So you were jacking off, were you?" she whispered. "Couldn't hold it back, could you? That's what it's like being a hung teenage stud. Your dick stays stiff all the time!"
Bobby's mouth gaped open in astonishment at her language. Donna sat next to him on the bed, licking her lips as he studied his drooling, pulsing cock. Uncontrollably she slid her hand up his thigh and wrapped her fist around the center of his hard dick.
It felt stiff and thick and warm, better than any cock she'd ever touched. Donna brought her other hand up to his prick. His rod was so long that the knob and several inches rose out of the twin grip of her fists.
"Donna, you better stop that," Bobby moaned fearfully. "We're gonna get in trouble."
"So you like getting your cock stroked," Donna moaned hoarsely. She began to move her hands up and down on his enormous dick, sighing as more jism oozed from his gaping cum slit. "Oh yes, I'll bet that feels so good to you. Your sister's soft hands, keeping your cock so long and hard."
Impulsively, Donna dropped her head to the shiny-skinned crown of his organ. She extended her tongue and licked quick circles around the tip of his cock, groaning with satisfaction as she felt the meaty shaft throb eagerly on her palms.
"Unggghhh!" Bobby's eyes lidded drowsily as he gave in to the new pleasure growing in his prick. "Oh fuck, Donna. That feels so… nice… mmmmm."
"Would you like me to suck it for you, Bobby?" Donna purred. Her cunt ached as she licked the underside of his spongy knob, darting her tongue onto his cum slit. "That's one thing you can't do for yourself, isn't it? Unless you've been giving yourself blow jobs."
Bobby winced and nodded his head hornily. Shamelessly Donna rubbed his throbbing cock all over her face, letting the seeping cream lubricate her chin and cheeks. Then she opened her mouth, as wide as she could and took the knob of his cock deep into her mouth.
His prick was even thicker than she'd expected, so enormous that she could barely stretch her lips wide enough to accommodate the shaft. Donna knew how obscene she had to look with her mouth stuffed with her brother's cock, but she hardly cared. All she wanted to do was taste and suck the burning hardness of his prick, to greedily gulp his jism when he came.
Forcing her lips wider apart, she took nearly a third of his swollen meat down her throat. Then she started sucking him off, compressing and puckering her cheeks as she rolled her tongue in circles around the crown of his prick.
"Ungghh! Oh fuck it, sis!" Bobby started to hump his ass, thrusting his gigantic tool down her throat. "That does feel good! Oh fuck, suck my cock harder!"
Donna sucked feverishly, slurping and gulping noisily as she lapped up the sweet pre-cum continually oozing from the tip of his cock.
Her lips started to hurt from being spread so far apart, and her cheeks reddened painfully with the intensity of the blow job. But Donna noticed nothing except her own lust.
Her hands moved all over his body, squeezing his thighs and chest and arms. Finally she wrapped her right hand around the center of his turgid prick and started to jack him off again, rhythmically tugging the loose flesh of his cock up and down.
