'Feel good, honey?'
'Mona… babydoll… ohhh fuck…' The hot sap was really flooding out now. Mona worked him gently, steadily, watching the way his cock jerked with a power all its own. Merle's balls hung loose and heavy in their sac. She thought of the billions of babies they would make. The danger of one of those tiny sperm getting loose in her pussy, swimming up into her womb made more juice soak the nylon crotch of her panties. But then she thought of Robby inside the house wondering where she was, what she was doing. She wiped her hand on the tail of Merle's shirt and reached for the door handle.
'I really have to go, darling,' she said, patting his knee. He looked really messed up. His big cock was still hard. It leaned to one side a little, one last dribble of cum making a line down the shaft. His cockhair sparkled with shiny droplets.
'Mona…' But she was out of the car, hurrying up the walk. She got her key in finally and closed the door behind her. After a few moments she heard Merle start up and pull away. Then she flicked off the porch light and walked quietly to the front room. The room was empty. She felt let down, almost disappointed. Then the pecking of a typewriter came to her.
Robby would be in his room working on his studies, of course. She'd been silly to think he had time to hang around waiting for her to come home. Mona went upstairs to her daughter's room. Sheri had fallen asleep with the bed light on. Half her covers were kicked off the bed, the other half were tangled around one willowy leg. They grew up fast enough as it was, she thought, watching her daughter's face change as she dreamed. The dream made Sheri moan under her breath. She was on her belly, legs spread. When Mona saw Sheri pump her pert bottom up and down she didn't think anything about it. But the young girl didn't stop doing it. Her ass began to move rhythmically, began to grind down harder as she pressed her pajama-covered mound against the mattress.
Mona turned and quickly left the room. It was natural, after all. Everybody had dreams. Even sex dreams. The change happened, that was all there was to it. Yet she felt uneasy after having watched something so instinctive, so basic as her daughter's hunger of the night.
She hurried to her own room and stripped her clothes and got into the shower. She felt slightly soiled after having given Merle that hand job. When she'd showered and dried and slipped into a silky nightgown, she still felt too tense to go to bed. She found herself padding down the hall again, heading for her brother's room. The typewriter was still now but a light still came from under the door. She paused there, thinking of how nice it was that Robby had come to stay for a while. He'd been going to school upstate, studying geology. Then a favorite teacher had moved down to Harrisburg to teach and Robby had transferred, too. The geology department was much better here, Mona remembered him saying. It was she who had suggested that he take the empty room. He was fixing up the place in his spare time to pay Mona back for her hospitality. Though she hadn't asked for any recompense, she was glad Robby was so handy with tools. Without a man around, the place had gotten a little shabby at the edges.
Mona put her hand on the doorknob, then took it back again. Sometimes it was hard to forget that they'd been brother and sister in another life, another house. Now it wouldn't be proper to burst right in without knocking first. She knocked.
'Want some coffee?' she called.
'Mona? That you? Come on in.'
Mona breezed into the room. She couldn't understand the lightness she felt, the tingle as her gown moved across her breasts. Robby was leaning back in his chair. He put down his book and pushed fingers through his thick, curly hair. His hair was brown, lighter in shade than hers. But he had her straight, graceful nose and full lips. Kissin' lips is what Robby had called hers. A flashing image of his lips on hers flicked through her thoughts. After an instant of shock, Mona regained her composure. Where had that little piece of erotica come from anyhow?
'Something wrong, sis?'
'Oh no… nothing. I just thought if you wanted coffee I…'
'Actually I'd rather have a beer. Coffee keeps me awake.' He put the cover on his typewriter and stood up.
They went down the stain together, Robby slightly behind. Mona had the strangest feeling that he was trying to see through her gown. On the last step, he brushed against her. His arm pushed against the large softness of her breast. Mona pretended to ignore it, but her thoughts were troubling. It had been an accident, hadn't it? She felt odd. Maybe because she hadn't seen Robby during those first years of college. And he had changed so much since the days when she was eighteen and babysitting him. He'd been five then. Mona had been his regular sitter right up until his tenth birthday.
'Hey Mona, you okay?'
'Of course I'm okay. Let's have that beer.'
Mona poured for both of them and thrown the empty bottles into the trash. She rarely drank anything alcoholic before going to bed but the occasion seemed to warrant it. She enjoyed her brother's company. They'd been friends while growing up. Not just because they shared the same parents either. They'd liked each other, gone to bat for each other in a pinch.
They drank the beer.
'You got any girlfriends?' Mona asked, feeling silly the minute the words were out of her mouth.
'Not at the moment,' Robby smiled back.
'Seems like I don't have the time or the money.' He smiled at her. Mona thought he looked suddenly younger. Like a kid again. Robby drank some beer. The kitchen seemed to be charged with some kind of excitement. Mona kept telling herself to relax. It was only her brother sitting there. And she was thirty-six… too old to let just one beer make her giddy.
'I don't think I really wanted this,' she said, putting own her bottle. 'Guess I'll go up to bed.'
Mona was halfway through the darkened living room when Robby caught her from behind. His hands went around her waist, but it was a brotherly hug, nothing more.
'I just wanted to thank you for letting me move in for while,' he said, kissing her cheek. 'My studies can a lot to me right now. What I mean is… I'm gonna pay you back some.'
'Rob you know I don't want anything! It's nice to have you here.' Mona could hardly get her breath. She let her hands touch her brother's waist. He was slender, so strong. Her skin burned with an unexplained thrill. She hugged him close to her, felt her large breasts giving softly as their bodies pressed together. The lips of her pussy were feverish, damp. What was happening? What was going on.
'Ohhhh…' She separated from him. 'I've got to go to bed… I'm bushed.' For a moment their eyes met but it was too dark for her to see Robby's expression. Mona hurried through the house and up the stairs. She closed her bedroom door behind her and leaned against it, panting.
'My brother. My very own brother…!' She let a hand fall to her side and lifted up her gown. As she dragged a finger across the puffy, warm lips between her thighs the tingle burst through her like a field of ripe flowers. She closed her eyes and moaned softly. And before she realized, she was crying quietly as her finger searched her slippery crevice.
'What's happening to me? What in God's name is happening?' But she couldn't get Robby's face out of her thoughts. She tried to think of Merle. She tried to imagine his cock sliding in and out of her body. But her brother's body seemed to take over her mind. His hairless chest, tan from summer play, his flat tummy. Soft but firm. His fingers knew how nice it was to touch.
'Noooo! It's wrong!' She fell on her back on her bed. Both hands clawed her cunt lips open. The velvety petals inside smacked as she dug at them. Then her clit was throbbing hungrily against her touch as she bucked her back and dug her heels into the bed and grunted like a wild mare.
As she came, the full fury of her imaginings spilled through her. Robby was on his knees between her legs. His young and slender cock was glossy with her juices as he penetrated her soft insides again and again and again.
'It's just a screwy daydream,' she gasped, flinging her head as if she might dislodge the intruding reverie. But the thought was too ravenously wonderful to get rid of now that she was convulsing with pleasure. She grabbed a pillow and hugged it against her belly as she plunged her ass in vicious circles.
'Robby…! Ohhhh Robby, ohhhh do it to me hard!'
And then she imagined Robby's cock jetting white cream into her belly. It didn't make a bit of sense. She
