John Kellerman: Sisters in heat

She got her hands inside his jeans and held his ass hard, feeling him fuck her. There didn't seem to be anybody at all around.

"Ohhhh… Ohhhh… Nat, will you take me with you next time you take the rig out?" His cock was almost all the way in her cunt now and she wiggled her hips to skewer herself completely. Nat had gotten her blouse open and was wetting her dark, long nipples. His eyes loved her tits, adored them unashamedly.

"Yeah." He hugged her close. She moved her belly to his. She still couldn't touch the floor with her toes and the steady grinding pressure was having an exhilarating effect on her clit. She bore down on the loving movements, concentrated on that tiny bead of pleasure until her cunt was thrilling to the jolts of ecstasy.

"Oh Nat… it's soooo good! I'm coming, coming, coming! And your cock is tearing me apart and I love it! I want to die with that beautiful thing inside me!"

Her bare foot banged against the door of the pick-up. Nat held her up with his prick, fucking her hard so that her ass rubbed up and down the metal surface. This time he held his emotions in check. She only knew what had happened when she felt a hot trickle of cum slip down the inside of her leg and drip from her pointed toes.

"Nat darling… I didn't know you were coming."

"I wanted to make sure you got yours first. I was afraid I couldn't hold on." He kissed her mouth, still working his cock in the depths of her pussy. The last of his seed foamed into the mouth of her womb… Marcia shivered, pressed her big tits against his chest so that the nipples would grind into him hard. Nat smiled at her. The noise of cars came to them in waves. "Let's get in this damned truck before the vice squad finds us."

Inside the cab, Marcia wiped the mess from between her thighs with her wadded panties and then leaned over to work on Nat.

"Leave it. I like the way it smells when I take a piss." She folded the thick cock gently into his pants and buttoned them up. He was watching her, eyes soft. "You want to try Denver with me? Would you take that much of a chance?"

Marcia was trembling with excitement. "God yes! I'd go with you in a second!"

Nat caught her hand, took the soppy, cummy panties from her fingers and held them to his nose like they were ambrosia.

"Might take some doing. I gotta dump that bitch of a wife of mine." He gave her back the panties and got the truck going and into gear. He paid the parking ticket and the truck bobbed up into the sunlit street.

"You know," Nat said, "Gloria never would put her mouth on my prick like you just did. She thought I was some kind of freak because I was so big. At least that's how she got out of giving me head."

Marcia pushed her lustrous hair from her eyes and took a deep breath. "Uncle Nat?"

"Yeah, sugar?"

"If you'd pull into the first motel you see, I'd sure like to let you come in my mouth." She shut her eyes, shivering from the thrill of her own words. The truck tires squealed rubber as Nat busted a sharp left into the lot of a big Best Western.

The two of them were still giggling and tickling each other when Nat walked her up the stairs, the key rattling in his hand.

"That lady wanted to know if we had any luggage." He slapped his thigh. "I said, 'Yes m'am, this was love at first sight so we just didn't have time to pack.'"

And then they were in the darkened room and Marcia was gasping with excitement, hurrying to get her man's tight Levi's down. And then her mouth was full and she was happy.

"I think it's wonderful that your sister finally decided to do something with her life."

Robin looked up at her mother. She swished her orange juice around, nodded. She hadn't really been thinking much about Marcia. Except that her older sis had given her that bottle of musky perfume she dug so much.

"Of course your father and I will miss her terribly. I wish she could have chosen a school closer to home. Denver seems so far away."

"Yeah." Robin was impatient for her mother to leave. She always went shopping on Saturday morning and Ralph was going to be on the golf course all day.

"Everything seems to work out for the best. Like your brother moving back home and apologizing to your father and all. I think he's becoming a very mature young man. And I was worried sick about him all the time when he had that apartment and wouldn't even call."

"Yeah, Mom." Robin moved her bottom on the hard chair. She knew that her hot little pussy was seeping butter. And she wanted to rub her nipples in the worst way. Her mother was putting a list in her purse.

"Oh, did you hear about your Uncle Nat? Ralph said he filed for a divorce. Gloria will probably keep the house." She shook her head sadly. "Marriages don't seem to last long these days."

"Think I'll go upstairs and take a bath," Robin said, getting up.

"You tell your brother that his father would like him to clean out the garage when he gets up. Don't forget now!" Robin watched her mom until she was in the car and backing out on the street. Then she padded quickly upstairs, her nightie sailing back from her slender legs as she worked the buttons loose.

Steve was stretched naked on his stomach in the middle of his bed.

Robin smiled, went quickly over. "You awake?" she whispered.

"Kinda."

She slipped onto the mattress beside him and began to stroke his asscheeks. He was warm and smooth and beautiful. She admired his strong legs, the blond wisps under each arm. Robin licked her lips, pushed them close to his ear.

"Everybody is gone."

"Oh yeah?"

"Yeah." She pulled at his waist. "Roll over."

Stevie rolled over. His cock was rigid and dark at the tip. Robin smiled like she'd known it all along. Her gown was parted down the front so she just left it on as she straddled her brother's hips and let her tits tickle across his chest. She moved the skin of his cock up and down as she wiggled her body back against it. When her juices had wet the glans thoroughly, she stopped moving and kissed Steve's lips teasingly.

"Guess what you have to go buy today?"

"What…" His eyes were still closed.

"You gotta buy some rubbers." She squirmed her trim ass from side to side and felt the swollen end of his prick sliding into her pussy another inch. "After this week we can't take chances."

She watched the effect her cunt was having on his emotions. He was breathing differently for one thing and when she suddenly arched her back and drove herself onto his hard cock, he grunted and tried to roll her over.

"Nope… me on top this morning."

"Ohhh God, Robin. You're absolutely crazy. You know that?"

"You love me?"

"Sure." He played with her red hair. "I love you all right."

"You like my hair braided or unbraided?"

He thought for a second. "I think I'd like it braided at first so I could take it down."

"We'll try that tonight."

"How can we with Mom and Dad…"

"Mom said I could move into Marcia's room now that she's gone to school in Denver," Robin blurted.

"That's the room next to this one."

"With a connecting bath." She opened her mouth and held it an inch from his. When he tried to kiss her, she pulled away and drove a tongue roughly over his ear. Steve pumped his hips up from the bed. Her pussy yearned, to be fucked. It was itching so bad!

"Robin… Ohhh Robin!" Steve kissed her neck and fucked wildly.

She felt the quick, sharp tickle of her come. If she was careful, she could draw it out for a long time, but it was hard in the morning. Usually she didn't last very long after waiting all night, after dreaming about her brother. Maybe when she moved into Marcia's room they could spend nights together, take baths together.

"Uhhh… Ohhh God, I never can hold onto the first one in the morning… Ohhhh Stevie, fuck me! Fuck me!"
