Ted watched the two kids through the crack in the doorway, happy that he could help them discover such a natural, wonderful source of fun and pleasure. He pictured himself with his own sister twenty years earlier as they, too, discovered the many wonderful ways there were to give pleasure to each other.
The man wondered if they'd fucked yet, and worried that Kristy would become pregnant if they had. He knew it was the next natural step for them to take, and Eric was probably plenty potent. Leaving the door open just a crack, Ted quietly went to his own room, opened his suitcase, and found the box of condoms he always kept with him whenever he traveled.
Some of the girls who came to his sex parties, especially the really young ones, weren't on the pill, and Ted insisted that boys wear a condom whenever they fucked one of them. He always kept a supply around, making it seem a normal and natural thing to do.
He took one of the foil packets out of the box and returned to the kids' bedroom. Pushing open the door, the man silently moved into the room walked closer and watched the two youngsters squirm on the bed as he listened to the wet, squishy sounds of great oral sex.
It was a minute before Kristy noticed the man standing beside the bed dressed in his bathrobe. With a small 'pop', her brother's cock slipped out of her sucking mouth as she raised her head up and grinned at her uncle.
The man smiled back.
"So, you've discovered what I was talking about yesterday, huh?"
"Mmm..yeah, it's fun. Why didn't you teach me this?"
"I can't show you everything in one day, can I?" he teased. "Here, I thought you and your brother might want to use this." He handed her the foil packet.
Immediately, Kristy realized what it was that her uncle had given her.
The girl smiled a wanton little smile and quickly tore it open. She seemed to instinctively know what to do with the rubbery circle, and placed it over her brother's cock as it lay, still shiny and wet with the juices from her mouth, across his flat lower belly.
After rolling the flesh-colored covering down the thirteen-year-old boy's shaft, Kristy rose up, lifted her pussy off Eric's mouth, turned, and rotated her body around the other way as she straddled his narrow, boyish hips.
Eric had heard his sister and uncle talking, but, with her crotch in his face, he couldn't see much except her fur-covered pussy. He did feel the elastic covering being rolled down his cock, but was surprised when his sister suddenly shifted completely around the other way, leaving her musky sex cream drying on his cheeks, mouth, and chin.
The horny teenage girl was hot for a cock and wasted no time. With her knees on the bed on either side of the boy's hips, she reached down between her parted thighs, lifted her little brother's cock upright, and guide the tip between her moist, furry pussy lips as she sat back and down onto him.
Kristy felt the little boy's cock head push between her large, outer folds and begin to penetrate her tight cunt hole. Leaving his shaft held firmly in place, she let go of his prick, leaned over, and put her arms on the bed on either side of his body. Lowering her body, the teenage girl sank her cunt blissfully down onto her little brother's condom-covered cock.
Ted stood beside the bed and a little behind Kristy. The older man had a perfect view of his nephew's hard little shaft as it disappeared inside his niece's pink sex slit. God, it was a sexy sight. He loved watching young kids fuck almost as much as he liked fucking young girls. And watching a brother and sister do it was particularly exciting, especially when it was their first time together.
Kristy wantonly ground her loins down fully onto her brother's small, stiff cock, twisting joyfully back and forth on the boy's rod as it filled her pussy. It felt soooo… good, though different than her uncle's. Although her little brother's sex shaft wasn't nearly as long and thick as Ted's, it still felt incredibly really nice inside her.
Maybe getting her cunt licked for the first time had made her especially horny.
The horny fifteen-year-old girl set up an immediate rhythm, her hips raising and lowering her body onto the sweet, lovely cock that plunged over and over again up into her slick sex slit. As her naked ass slapped down onto the flesh of her brother's thighs, her T-shirt fell down around her hips, making the girl look as though she was partially clothed.
Ted thought dressing in a sexy way was an important and erotic part of good sex, and the sight of his panty-less teenage niece, dressed only in a T-shirt and bouncing up and down on the little boy's cock, was making his already stiff cock drool with moisture. The front of his terry cloth bath robe was tented-out by his erect member, and the man slipped his right hand in between the flaps of his robe and grasped his thick, throbbing cock.
God, she looks sexy…he thought to himself as his hand slowly skimmed up and down over the smooth, warm surface of his erection. The belt around the robe was getting in the way so, with his left hand, Ted pulled the knot apart and the front of his long, heavy bath robe fell open.
Kristy was totally involved in the wanton act of fucking her little brother. With each delightful collision of their bodies together another shiver of lusty pleasure shot through her body. The base of the boy's cock was making perfect contact with her sensitive, swollen clit, and the indescribable heavy warmth of sexual orgasm was already beginning to build in her loins as she pounded down onto his hard little cock. She loved sex; she loved fucking; she loved doing all kinds of sex things with men…and boys…
The girl noticed her uncle standing closer to her, his robe open and his thick member sticking out. She saw the man's hand working slowly up and down the fleshy rod.
"Mmmmm…can I do that?" she asked in a quiet, little-girl voice.
The man moved closer, and his teenage niece reached out and wrapped her fingers around his thick, swollen sex rod. The fifteen-year-old girl pumped her hand up and down the smooth, velvety shaft several times, but found that her fingers weren't sliding very easily.
She realized what she had to do — what she wanted to do, and bent down.
She didn't have to bend over very far before she took the red, sculpted tip of the man's cock into her sweet mouth.
It wasn't easy for her to maintain her rhythmic fucking on her brother's prick and suck on her uncle's cock at the same time, but she was sure going to try. Up and down her body moved, the tempo of sex never wavering as she held the top of the man's sex shaft in her mouth. She grasped the pulsing member near the hairy base with her left hand to steady it as her hips and ass continued to slap fast and hard down onto Eric's loins, his shaft poking up into her. Her mouth coated the man's cock with her spit as she made the sexual connection over and over again.
The young boy had closed his eyes, his mind a complete fog of sexual splendor. He lay completely still and let his fifteen-year-old sister move up and down on his cock, letting her be in control, letting her control the tempo of their fucking. All he wanted to do was lay back and enjoy this incredible thing that was happening to him for the first time in his life. Masturbating had always felt good, and having Kristy do him with her mouth last night had felt, well, great, but this…this was indescribable.
It wasn't long before the boy felt the familiar stirrings in his balls as his orgasm built. With his eyes still closed and his mind floating, he relaxed and let the sensations suddenly build to a huge sense of tension followed by an immediate feeling of release as his cock finally exploded inside his sister. As he felt himself cum, the young boy grunted, arched his back, and raised his hips up against his sister's loins. He reached his up hands and grabbed the young girl around the waist, stopping her motion over him and holding her down tightly onto his spewing shaft.
