John Kellerman: Sisters in heat

Robin grabbed the tennis racket she'd borrowed from a friend and bounced down the hall in her new tennis shoes. She didn't even know how to hold the damned thing, but her folks didn't have to know that.

Her mother was puttering in the kitchen so Robin climbed the stairs quickly and sneaked into Marcia's bedroom. She found the bottle of perfume on the dresser, dabbed it behind both ears and on her wrists. She was about to put the top back on when she remembered another important place. She got two big droplets on the tip of her finger and spreading her thighs, pulling down her panties, she wet her dainty pubes. It felt sexy to have that scent down there and she knew that if her cunt got really hot it would really smell nice.

Sure, she was going after Stevie. She wanted him so bad. She wasn't even afraid to admit it to herself. She took a last look, this time in her older sister's full-length mirror. She looked pretty damned good!

"Robin, are you in your sister's room?"

"Uhh… looking for something, Mom." Robin hurried downstairs with her racket.

Her mother was drying her hands as she started out the door.

"And what is that smell?"

"See you later, Mom."

Stevie's jeep was parked in back when she came up the alley. It always made her heart skip when she saw that he was there, when she knew her trip had not been wasted. Of course she hadn't so much as spoken to him on the phone since that last strange time.

She was breathless with excitement as she started up the weedy, overgrown back yard. But she sensed something was wrong, even before she reached the back step. A voice, two voices through the small window at the corner. A girl's voice in her brother's room.

Robin bit her lip, frozen there with the racket clenched under her arm.

There were too many emotions running through her for Robin to know exactly how she felt. Over it all was a vague sickness in her stomach. She went over to the two big bushes that partially had the window from view. She looked guiltily from side to side. A peeping torn was what people called them. At least no one would see her in the bushes.

She pushed the branches apart and moved into the leafy, green shade. The window was all the way open, the curtains sucked out through the screenless space. Robin listened.

"I just don't like the taste of cum," said the whiny, female voice. There was the faint sound of two wet things brushing together… lips maybe or…

"Please, Linda… you don't have to swallow it." Steve's voice. It was strained with passion.

Robin stood on tip-toes, peered over the edge of the windowsill.

Her brother was on his back on the bed, a dark-haired beauty kneeling between his spread thighs. She was about Robin's size but probably older. She had Steve's cock in both hands and was bending over it with open mouth.

Robin had to choke back a cry of lust as the girl named Linda brought the tip of her tongue slowly up her brother's cockshaft and then tickled the head with fluttery movements. He thrust his hips up, trying to push his prick into her mouth. But the girl giggled and jerked her head away.

"I know how a guy gets so crazy… you'd grab me and keep it in there until I'd have to swallow it." Linda opened her mouth, took Steve's cock inside for a few teasing seconds and yanked it away again.

Steve moaned, pumping his hips helplessly.

"Come on…" he begged.

"Let's just fuck."

"We already fucked." Steve grabbed at her hair, tried to push her lips down.

Linda pulled away and got off the bed. She was inside a pair of jeans and pulling on a T-shirt before Steve could get to her.

"I've got to take my little brother somewhere. I'll be back after that."

"You sure you're not mad?" Steve kissed her.

The girl smiled. "No. I'll be back if you want me to."

Steve's look told her that. Robin felt like screaming or crying or both. She ducked behind the bushes as the girl went out and down the walk. When all was quiet again, she hurried to the door and banged.

"Robin!" Steve's face was a mixture of pain and pleasure. He'd pulled on a pair of cut-off jeans but that was all. Robin could tell by the way his cock lumped down one leg that he wasn't wearing skivvies.

"I'm supposed to be playing tennis." She smiled, shrugged. She was trying so hard to be cool. But looking at her brother's chest, his long, sinewy arms, his freckled face. She could hardly contain the hunger she felt.

"Come on in." He held the screen open. "But just for a second. I've got somebody coming over pretty soon."

She stepped past him, threw the racket on a chair. "Anybody I know?"

Robin knew he had been looking at her ass when she turned. His eyes flicked away like he was ashamed. She gave him her ass again, hoping he'd take another long glance. She knew that she looked sexy in that pleated tennis skirt. She swished her ass a little, letting Steve see the lace bikinis underneath.

"Listen, Robin… I'm sorry about what happened last time you came over…"

"It wasn't just your fault," she said, "I helped."

"But it was wrong… and that's why I think we'd better cool it for a while." He went to the window as if he might be expecting that girl back any time.

Robin was suddenly angry. "What do you mean, cool it?"

"I mean not see each other, you know." He still had his back to her. He couldn't look her in the eyes.

"After knowing each other this long, after loving each other… you're telling me we can't see each other any more!"

Steve turned but didn't look directly at her. "Oh, later we could… just be friends like before. But…"

Robin went over and stood close to him. She was breathing hard. She knew that the perfume was warming on her skin, that Steve must smell it by now. Marcia always used it so it had to be sexy.

"Steve?"

"What?"

"Hold me a second. Just hold me…"

Steve looked at the ceiling, frowned. "Damn it, Robin."

"Just for a second. I've been crazy worrying about you and how you must have felt after the time we spent there in your bed."

"Don't even remind me." He started to turn away, but Robin caught his arms.

"Steve!" She put her cheek against his chest. Then ever so gently she let her thighs come forward. Yes, the cock-lump was still there. His prick was half erect excited.

"Hold me. Just hold me for a second and then I'll leave."

"Promise?"

"Yes, promise."

His hands curved over the top of her shoulders and she sighed with hot emotion and wiggled her tits against him. Her tits were mashed against his chest and she was lifting her thigh again into the heat of his groin.

Somehow she got her hand down and the first button of his cut-off jeans unbuttoned before he grabbed her shoulders and tried to thrust her back. Too late. Her hand curved around the heavy, hot meat of his cock. She squeezed it hard and began kissing his arms and chest.

"Robin… damn you!" Steve staggered back, fell trembling into a chair.

Robin was on her knees between his legs in a flash. She knew she had only this one chance to have his cock again. And despite the guilt he felt and was making her feel, that hunger had to be sated. Or she knew she'd die!

Now her own juices were working. The silken crotch of her bikini panties was absolutely soppy. And the scent of the musky perfume permeated the room. Stevie's face looked slack, dazed.

She had his shorts open at the fly now and his cock stood stiff and straight and beautiful in her hands, his loose-hanging balls below. And Robin knew she had to do the one thing which would win him. That thing the other girl wouldn't attempt. She swallowed her fear and looked at the swollen, dark glans of her brother's prick.

"Stevie… I… I want to s-s-suck your cock!" Even the words had brought chills of fear into the pit of her stomach. Cocksucking was so foreign to her… she had only heard whispered stories in the past. But after hearing her brother begging that strange girl she knew it must happen. She loved Stevie enough to have a try.
