For a week, Mona tried to stay out of her brother's way. That night in the kitchen had greatly disturbed her and she didn't want to invite more irresponsible daydreams or night dreams into her life. She consoled herself by thinking of the short, intense episode as somehow natural. It was natural for brothers and sisters to have passing thoughts about sex with each other. The trouble with her thoughts, though, was that they didn't want to pass.
Robby only left the house for his classes and spent the rest of his time either in his room studying or watching the late movie before going up to bed. Mona went to a show with Merle but the evening had ended with an argument. She felt edgy and antagonistic when she was with him. When he dropped her in front of the house and she was safe inside, she felt relief more than anything. But there was a sadness too. Merle had been very nice to her. And now she was falling out of love with him.
It was Thursday evening. That meant school the next day for Sheri. But instead of finding her daughter working on her studies or getting ready for bed, she discovered her lolling on the bed in Robby's room. Robby was typing something, flying to work around the endless chatter coming from Sheri.
"What are you doing back so early." She cracked. "You and Merle have a fight?" It was that straw that pushed mom's anger over the edge.
"You go to your room. Robby has work to do and he can't get it done with you blathering in his ear half the night." Mona met Sheri's uppity stare. "I mean it, Sheri!"
"Oh shit, I'm not even allowed to speak to my uncle when I feel like it!" Sheri stomped around the room. Robby bent over his typewriter like he wasn't hearing anything.
"Sheri, I don't want to hear this. Do as I say!"
"I'm going to go to Annie Faber's," Sheri snapped finally. "I'll be back later…"
"It's too late to go out… it's a school night."
Mona grabbed at her daughter but Sheri pulled away and trotted down the hall. Mona felt embarrassed rage. She looked at Robby as he turned.
"What can I do with her? She's gotten to that age… you know."
Mona sat on Robby's bed. "You talk like you're ancient. Or have you forgotten you're only twenty yourself."
Robby grinned. "Guess I forgot." He turned to peck another sentence or two, then stopped to correct a mistake. Mona watched his shoulders move under his t-shirt. She felt the old affection for him. The other, naughtier passions she kept locked away.
"Why don't I go fix you a snack and bring it up?" she said. "I bet you're hungry."
"That'd be great, Mona. I could dig it."
It didn't take her but a second to change into her nightgown. Then Mona hurried downstairs and put together a ham sandwich with plenty of mustard – just the way Robby liked it. She opened a beer too and got everything on a tray and carded it up to his room.
He took a couple of bites of the sandwich and washed it down with beer. She felt comfortable again watching him. She could almost remember the times when they'd been kids. Running and hiding in the big hour the parents had. She let the thoughts play through her mind until one she didn't like threatened to invade. Where did they come from? The nakedness… she hadn't thought they'd played together naked so much. Her and Robby. She shook the images away and stood up.
"Well. I hope you enjoy your sandwich. I guess I'd better get to bed."
"Mona, wait…" Robby caught her as she put her hand on the knob. His fingers brushed her waist. There was so little between them she could feel his warm hand on her flesh. She turned. She felt faint. Robby was looking at her so strangely.
"Mona. There's something on my mind…"
"What is it, darling?" Mona remembered how she'd called him darling as a child. But only at certain time. More images flicked through her head. Robby's cock. In her hand. When had that happened? Or was she just dreaming everything?
"Mona. I… I…" Robby stopped and took her hand. "I've been remembering things. How we used to… play."
"I'm sleepy, Robby. I'd better get in bed." She started to open the door but Robby forced her gently away. Forced her back against the wall. He was getting very close. She tried to keep her jutting nipples from touching his chest. They were so big her breasts. She'd always been embarrassed as a young girl because of their size. Robby's hand touched her belly. Mona closed her eyes. She had to get hold of herself. She was thirty-six years old with a daughter. Robby was twenty. Robby was her brother. Her flesh and blood. What was he doing with his hand?
"You're so lovely," he breathed, trembling. "I've thought of you like it used to be…"
Mona's mind raced. How had it been?
"Robby, don't you think I'd better leave?"
"No." Robby pressed his body up against her. The nightgown seemed almost nonexistent now. Why in hell had she put it on? What had she had in mind? Was she leading her own brother on? God no! She wanted out of here! She wanted…
"Mona. Ohhh God, Mona!" His mouth dipped close and their lips brushed. Mona wanted to turn away but she was petrified with shame, fear, confusion. It felt so good! His lips! When he tilted her head slightly, she let him. Her mouth opened. His tongue flicked between her teeth. Darling Robby. Lovely, lovely Robby.
"No!" She put her hands on his shoulders and tried to force him back. "Robby, get away! What are you…"
"You're everything I've always wanted in a woman," he gasped. His hands traced the outlines of her body. Her slim waist, her full, soft hips. Then be kissed her gently on the full, white tops of her breasts. Mona's knees wobbled. She let out a breath and leaned heavily against her brother. "Ohhh Robby, this is awful…"
"It's wonderful." He licked her plump orbs carefully, like a cat might do. She felt a burning tickle between her legs. Robby was inching a hand under her nightgown. She put a weak hand down to stop him, but he forced past her resistance. Now his fingers brushed the skimpy crotch of her panties. They were damp already and his touch seemed to open her springs completely. Mona sighed as she felt her sex butter flood out to drench the sheer nylon. Robby kissed her neck, ground his body against her as he dug gingerly against her silken-covered pubes.
"I remember when you first started growing hair," he said. "I was just two or three, but I remember."
"Robby… stop this… stop!" Mona's body shuddered. Robby was working his finger under the edge of her panty crotch now. She clutched frantically at him but he ignored her. She felt one plump lip being pushed to the side. Then her back arched and she banged her head back against the wall.
"Nhhhoooo!"
"Oh Mona… Mona…!"
"Robby… don't do this… Ohhh, I'm begging you!" But suddenly she felt his finger penetrate. Her insides curled around his knuckles. Her hole tightened down on him, convulsing in the instinctive movements of fucking. She heard the smacking, sucking sounds as he moved his finger around inside her. Her hand fell away weakly. Then she clutched his shoulders and let him kiss her again, moaning through her nose.
It was when Robby tried to edge her over to his bed that she broke away. She tripped at the door but managed to stagger out into the hallway. Robby came close behind. He caught her waist halfway to her room, spun her around.
"Robby, do you have any idea what you're doing?" She felt she had a little control back. She was angry at her brother, much as she loved him. "This is awful!"
"Mona… I've got to have you! Like we almost did when I was younger."
"Stop talking about the past. I don't remember half of what went on."
"Half was enough…"
She broke away from him again. This time she made it to her bedroom and had the door half shut when her brother jammed his foot in.
"Go to bed," she gasped, near tears. Robby forced the door open with his shoulder and slammed it behind him. It was dark in the bedroom. The only light came from the partly open bathroom door. Mona watched him strip off his t-shirt and fling it on the floor. She swallowed hard and stepped backwards until the backs of her knees struck the bed. Robby was stepping out of his jeans now. When he peeled down his shorts, Mona tried to look any. But she couldn't keep her eyes on his cock. It was long and slender. More slender than Merle's fat prick. And Robby's organ had a youthful beautify to it. It looked clean and graceful and so stiff!
"Robby. I want you to turn around and get the hell out of my bedroom. Now!" But her voice broke at the last. She hadn't sounded as tough as she'd hoped. Robby caught her around the waist and dumped her onto the bed. She struggled like a hellcat.
"Mona… damn you… you want it as bad as I do!"
"No… Nooooooo!"
They wrestled, Robby struggling to get his legs between hers. Mona lifted a knee once and almost connected, but Robby caught the blow with his hand and held her down while he ripped the top of her gown open. Both of her large breasts bounced free and Robby buried his mouth between them. Then he kissed his way to a nipple and began to suck voraciously. Mona tried not to feel what was happening to her. But that was impossible. The rub of her brother's strong, wiry body against her soft female flesh was unbelievably exciting. Still, she had vowed in her mind that this wouldn't happen. This… perversion.
"Don't… don't… Ohhhhhhh uhhuuuhh!"
Her gown was pushed up to join the tattered shoulder straps. Now there was just a tangle of silk sound her waist and her panties. Robby grabbed the crotch band and tore her panties away with a laugh.
"Oh God in heaven!" Mona bawled, fighting hard again. Robby wedged his hips between her thighs and worked his rigid cock closer to her cunt. She could feel the slick juice drenching her dark, thick curls. Robby pinned her wrists against the mattress and managed to ease his cocktip between her plump outer lips.
Mona bucked like a mule. But Robby had the advantage of strength. And he had another power too. He was the male, the penetrator. She saw all this in a flash. He wanted to mate with her. The fact that she was his flesh and blood, his sister, didn't matter at all. His cock was hard. It was an inch away from paradise. Her paradise. She tried to bite him, failed. He mouthed her breast until the hot fires licked up and down her body. She couldn't sustain the struggle much longer. Her muscles gave, her body went a little limper.
"Mona… Yesssss!" Robby bound her mouth. She tried to muster her waning strength enough to sink her teeth into his lip. But at that instant, Robby lunged forward and his back humped up as he drove his cock into her pussy.
"Uhhhhnnnnnn!" Mona felt it go. She felt every inch. She felt the flared, swollen head, so hot and smooth. She felt her insides spasm around the invading meat. She could hardly breathe. Then Robby moved again and rubbed against her mound. She went limp completely, her head flopping on the pillow as Robby began to fuck her slowly and deeply.
"This is the one thing we never did," he whispered, letting her wrists go now, circling his arm around her waist. Mona couldn't speak. That long hard shape inside her was so fantastic! It delved deep, deeper. She clenched the big muscles in her thighs and tried to squeeze it. Robby grunted as her velvety lining caromed and sucked against his barbed head. He gave her a sloppy kiss on the neck.
"Oh Robby… what are you doing to me?"
"Fucking you. I'm gonna fuck you all night!"
"Ohhhh God… we can't go on! We can't let this happen!"
In answer, Robby slid his palms down under the cheeks of her ass. Holding her up like that, he jabbed his cock so deep that the opening to her womb tingled deep, deep inside her. Mona tried to say something else but the words turned to babbling. She found herself clutching her brother's back, digging her nails into him. Her legs kicked involuntarily as the tensions broke inside her. She felt her flesh melting against the strong embrace of her young brother. She started being herself in the consuming pleasure that he brought with every moment of his cock in her pussy. She had his neck and chest and caught his head so that she could devour his chin and lips. Robby kissed her back with feverish urgency. His cock felt like it was growing inside her.
She spread her thighs wider and bent her knees sharply, pawing her feet in the air. She felt a thousand rivers of excitement rushing through her. They met at an ocean and she screamed as the torrents of ecstasy made her body buck and jerk. The cum lasted five pounding seconds but Mona could feel another one close behind.
"I can't believe this," she cried, biting her brother's shoulder. But her second convulsion exploded then and she choked and twisted in the aching throes of more pleasure than she'd ever experienced.
"Mona… Ohhh God, I love you, Mona."
Robby's forbidden words brought yet another trickle of excitement to her loins. But now the cum was gentler, easy to ride. She kissed his mouth sloppily, riding the trembly glow that his sliding cock gave to her again and again and again.
She felt Robby's back stiffen, felt his breathing constrict. She petted the back of his neck and cooed to him, barely able to make words. He fucked her furiously now. She knew he was about to cum. He hurried, panting with the fire that hung just out of reach.
"Robby… darling… cum! Ohhhh, cum inside me!" And she found herself wanting it. Wanting her brother's sap to fountain against her womb.
"Mona… God… Ohhhh fuck… fuck!"
"Yeah… do it… Ohhhh, do it now!"
Robby's back arched and for a second he was paralyzed as the first explosion ripped through his young body. Mona clung to him wildly, pumping he full hips up and down as she felt the hot jizz froth front the tip of his cock.
They searched for each other's mouth and kissed, moaned, fucked. Mona felt a gentle tickle, almost came again. Then they were limp. Motionless except for their tortured breathing. Mona didn't know how long it was until Robby rolled off and nuzzled against her side. She lay there exhausted. The slick cream leaked from her hole but she didn't care. She let it dribble, let Robby's hot cock rest against the side of her leg. Then she felt the guilt building. The shameful truth of what had just taken place. It grew in her like a sick, soft thing.
"Robby. Would you please get your clothes and get out of here?" She fought to hold back her sobs. Robby tried to put an arm around her again but she pushed him away roughly. "No."
In the half light he dressed and went to the door.
"Mona…?"
"Get out, Robby. Get out."
When the door closed behind him, Mona buried her face in her pillow and bawled like a baby.
