Nate got his arm around both their waists and cuddled in the middle of the big bear rug. Rebecca felt a little strange in the skimpy sex outfit he'd chosen for her. But Tammy seemed to feel at home in what she was wearing. Nate fooled with the top of her bodice, finally pulling the string that was tied in a bow at the middle. The top of the bodice opened back, and just as Rebecca had suspected, Tammy's plush tits bounced free. The nipples were already engorged with blood, dark little fingers of excited flesh. Rebecca felt her own nipples throb in sympathy as Nate bent down to nuzzle against Tammy's nubs. The redhead whimpered and arched her back, pushing her shoulders as fax back as she could. Her tits rose to Nate's mouth and he sucked at them wetly as the girl trembled and curled her fingers into the nape of his neck.
A gamut of emotions went through Rebecca. She strained against Nate's embrace but he felt her puffing away and suddenly his mouth was gliding wetly along the lace edge of the clinging satin cups that hid her tangerine-sized breasts. He mouthed her nipple through the sheer material. She groaned and let out a breath. Slowly, gently she felt herself being urged down onto the floor. She saw with surprise that Tammy was there with her. Between them, Nate hovered, his hands petting their young tummies.
"Ohhhh," Tammy moaned, pumping her hips.
Under the tight, white satin of her bodice, her red-haired cunt glistened. Nate had them on their hands and knees as he began to rub their bottoms. Rebecca felt terribly sinful. It was bad enough letting a male do that anyhow but to allow him to do it to another girl simultaneously seemed terribly perverse. She couldn't decide which of the warring emotions inside her would win. One moment she was shivering with the thrills from Nate's bold fingers. The next moment she felt whorish and evil and certain that when this was all over she would be punished by her aunt in some weird manner.
"Such hot, tight little quims," Nate breathed, letting his fingers slip into Rebecca's crevice. A slurpy sound nearby told her he was doing the same thing to Tammy. And Tammy's head hung down between her braced arms. She was panting, tongue lolling from between her teeth.
"Uhhhh," Rebecca groaned, closing her eyes. Nate's finger teased her clit to firmness and then slid down along the dripping folds to her throbbing hole. With a quick little thrust he was inside her. Rebecca humped and arched her back. Her hips made twitching, excited circles as he began to fingerfuck her deeply, pulling his finger out so slowly that she drooled down her chin.
"Ohhh, Nate, ohhhh I can't think straight."
"Who needs to think when you're playing?"
Tammy glanced dazedly at Rebecca. Her red hair half covered her face but Rebecca could see that the girl was lost in the enjoyment of Nate's finger sliding in and out of her cunt.
"Rebecca," Nate said, "I want you to listen to me. I'm going to get nice and hard and then I'm going to fuck you."
"Ohhh God," she gasped.
"Do what I tell you now." He positioned himself behind Tammy. The redhead sensed that she was about to be mounted and began to thrash her curvy ass around like she could hardly wait. "Take my cock, Rebecca," Nate ordered.
Rebecca put her fingers out to his groin and curled them wound the hot, stiff shape. His foreskin had slipped up over his glans and as she tightened her hold, she watched the clinging flesh slide back to expose his magnificent tip. It was dark blue now and glistened with his body's natural lubrication. A few inches away Tammy's ass danced eagerly. Below the cleavage of her cheeks, Rebecca could see the swollen membranes of her cunt. Her outer lips were plump with blood, the tight red curls clinging damply together.
"You put it in, Rebecca." Nate said. He hugged Tammy's belly as he eased his cock forward. Rebecca was trembling. She felt like the most wicked person in the world. How could she let herself go on behaving like this? It was some kind of crazy orgy he wanted. And she wasn't that kind of girl. But to watch his streamlined glans pressing against Tammy's slippery folds was too excruciatingly sexy to think of stopping.
Nate thrust forward gently and there was a wet sound as his cock went between Tammy's inner labia. Tammy couldn't keep still with that smoldering knob touching her. She bucked her ass up and down and made a whinnying sound. Kneeling lower, his knees between her legs, Nate thrust again and Rebecca's fingers felt his cock throbbing with excitement as his glans pushed into the heated depths of her crevice.
"Push it up another inch," Nate ordered. Rebecca squeezed him hard behind the glans and tried to guide his cock, against where she thought Tammy's hole must be. There was another gasping sound from the trembling redhead and Rebecca knew she'd found it.
"Yeah… now here we go!" Nate bit the redhead's shoulder and this time his ass muscles bulged as he forced his glans into Tammy's body. The girl let out a pent-up breath and pawed the rug. The sucking wet sound as her cunt was half filled with cock made Rebecca jerk her hand back. She stared, hardly believing that this was how it looked when a girl got fucked. That prick looked so big! So thick! Yet as Nate continued to jab at her with hard, quick movements of his hips, Tammy's young body opened for him. A rivulet of juice spilled down the girl's thigh. Some dripped down Nate's shaft and into the hair round his balls. He pumped harder and the slurpy sound came again as his shaft buried itself another inch into the feverish, slick heat.
"Uhh, uhhhhh!" Tammy moaned, her head flopping wildly. "Ohhhhh get it in me! Ohhhh fuck me forever! Ohhhhhh, Nate!"
"Yeah, you red-headed bitch! You lovely, tight-cunted bitch!"
Rebecca was affected strangely by Nate's language. She was surprised to find herself almost wishing he'd called her that. The skimpy little panty-bra outfit slid against her skin as she sat on her haunches and watched Tammy take Nate inch by throbbing inch.
"It's getting deep now, baby," he groaned. His fingers held her shivering ass as he plumbed her pussy. It looked like Tammy was about to flip out. Rebecca started to crawl away. She was scared. Scared to have that huge erection shoved into her own immature body.
But then Nate's balls swung forward against the underside of the redhead's buttocks and at the same time he reached out to grab Rebecca's wrist.
"Don't be going anywhere. I'm ready for you now."
"Nooo!"
"It's nice and slick. Nice and hard."
"Ohh God, it's gonna split me apart."
Tammy began to whimper. "Don't pull it out, Nate! Ohhh please don't! Keep fucking me so I can come."
Rebecca watched the redhead's big tits jiggle as she humped her back, making her pussy tighten around Nate's rigid prick. It was obvious that he didn't want to pull it out. But Rebecca saw too that he wanted to feel what her cunt was like even more. With a wet, squishy sound his cock came free of Tammy and he turned, the bobbing hot shaft all shiny with the girl's juices.
"I'll take care of you later," he told Tammy. "Just grab her wrists and pin them back on the rug."
"Nooo!" Rebecca squealed. But Tammy seemed half hypnotized by Nate's urgent passion. She pinned Rebecca's wrists as Nate had ordered. Rebecca flopped around on her back, her legs kicking. Nate pushed them apart and lowered his body between her thighs.
"Uhhhhhh, uhhhh, it's gonna hurt!"
Nate's lips brushed her mouth. "Easy now, baby, just take it easy." He kissed her hard and hot, his tongue giving her a preview of what he had in store for her young pussy. Rebecca tried not to respond but soon she was nursing on his tongue, lost in the surging pleasure that his hands brought to her breasts as he peeled the red satin cups down. He licked her nipples until both of them were standing straight up from their areolas.
