Wave of wave of intense pleasure roared through his body, each one accompanied by a grunt or moan from the boy. Each spasm of his cock inside his sister's tightly gripping cunt sent another jolt of wondrous sensations exploding in his brain, and he held her body tightly connected to his. He'd never cum this hard before, and it felt like it would go on forever.
Kristy could feel her brother's cock pulsing inside her much the same way her uncle's did when he would cum inside her. It felt so wonderful to the sexually turned-on young girl, and she was pleased that she could make the boy feel so good. She almost laughed at the silly whimpering sounds he made as his balls emptied into condom inside her, but laughter was impossible with her uncle's deliciously smooth, throbbing cock filling her mouth.
Ted was really horny, now, from watching the two kids fuck and having Kristy so eagerly mouth his shaft. He felt that urgent need to get off and, while enjoyable, the girl's oral technique was still not very good.
The man put his hands on either side of his niece's face and pulled his hips back, releasing his cock from the grip of her lips.
"Scoot back a little and get on your hands and knees."
Kristy was eager to do what her uncle wanted. She sat up and felt her brother's shrinking shaft pull out of her, then moved backwards on her knees to the foot of the single bed. Ted shifted around to the end, too, and placed his hands on her hips guiding her backwards until her feet stuck out just a little over the edge.
Eric moved the other way, towards the head of the bed, where he pealed off the filled latex covering from his flaccid prick, set it on the floor, and lay back against the headboard. The thirteen-year-old boy was completely relaxed and unashamed of his nakedness as he watched his uncle step up behind his kneeling sister. The boy knew the position from watching the two of them the night before.
The man moved in between her feet, his hard, pale, fleshy cock sticking up so straight and tall from his loins, pulsing slightly with each rapid beat of his heart. The teenage girl's smooth, naked behind stuck up a little, and Ted admired the sexy view for a few seconds before tilting his cock down and pressing the tip between the folds of his niece's deliciously sweet little pussy.
Kristy groaned at the barrage of sensations that shot up through her body from between her thighs as she felt her uncle's cock separate the lips of her pussy and enter her. Eagerly, she pushed her ass firmly back against the inward penetration and felt the man's thick sex shaft slide so easily, so completely, so wonderfully up inside her.
Ted held the youngster by the hips as he began to immediately pound his cock into the young girl from behind. This wasn't the time for niceties — it was time to fuck, and fuck hard. The older man was surprised to discover that the fifteen-year-old girl was taking the full length of his cock inside her, and he felt his balls swinging and slapping against her wet, drooling slit with each deep stroke into her wonderful little cunt.
The breath hissed from Kristy each time she felt her uncle's wonderful cock punch deep into her. God, it felt so good, so fucking good, even better than yesterday. The fullness, the thickness,
the sex…the cumming…
"Oooohhhhhh…."
The teenage girl's climax was suddenly there, suddenly overwhelming her body and mind. The intensely pleasurable sensations that came from nowhere and rippled through her like flashes of heat exploding in her brain caught her by surprise. She cried out, her eyes squeezed shut as she felt her cunt muscles grip her uncle's long, hard cock that was still pummeling her so wonderfully from behind. The early morning fuck with her little brother had gotten her really hot, and now her uncle's big, thick cock thrusting again and again into her, the base slamming against her sensitive clit, got her off quickly and powerfully.
The man smiled as he heard and felt his niece cum, his own climax very near. Of all of the sexual positions, he loved fucking young girls from behind the best. The sight and feel of their tight, firm, little ass on his loins was great, and it usually made him cum pretty fast. This morning was no exception, and shortly after entering the young girl the man felt his climax well up from deep between his legs, his balls beginning to contract as they got ready to shoot. Slowing down, he took four more long, deep strokes into the young girl's delightfully tight fuck hole just as he felt his balls throb and send spurts of hot male cream deep into her cunt.
Gritting his teeth and grunting, he held the fifteen-year-old's butt tightly against his loins as he shot of into her, her smooth, round ass cheeks pressing and rubbing against his lower belly. Intense sensations of incredible sexual pleasure rippled through his body, and he moaned out loud with each delicious throbbing spurt of his shaft. God, he loved cumming inside young teenage girls. There was something especially sexy about shooting off into their fresh, hot pussies.
Through the fog of her own powerful orgasm, Kristy could feel each spasm of her uncle's cock as it pulsed and sent wades of cum coating her insides. She wiggled her ass back against him, loving the feel of his climax inside her and the thickness of his cock filling her up between her legs.
"Mmmmmm…God, that was good," the man finally said, as he slowly stepped back and his softening cock slithered out of his niece's slimy snatch. "What a way to start your morning, huh? God, do I need a shower.
I think all of us do…see ya later."
Ted tied his robe together and headed for the bathroom. He was only a little surprised when his niece joined him in the shower a minute later, and they enjoyed soaping each others' bodies as the hot water sprayed over them, the after-glow of great sex leaving them content and relaxed.
Chapter 5
Ted left later that morning, headed for another city in his sales territory. Kristy's mom returned from the hospital shortly after, exhausted from the hours of work she'd put in over the last couple of days. Fortunately, it was the weekend, and the kids and their mother could rest and recover from the physical exertions and the lack of sleep they all experienced, though from different sources.
The two teenage kids kept quiet about their activities of the past day.
Kristy knew her mother's secret, but didn't feel it was the right time to talk about it now, or let her know what she, her uncle, and her brother had been up to the past couple of days.
Monday brought a return to the school week and a return to the normal routine of the household, though not entirely as it had been. Kristy and her brother had discovered the fun, excitement, and sheer physical enjoyment of sex, and there was no stopping once the kids felt the intense pleasure it created in their bodies. The two teenagers found lots of time to enjoy themselves, and the box of condoms Uncle Ted had left didn't seem to last very long.
Several weeks later, the kids' mom, Becky, got off work earlier than usual in the afternoon and headed home. Normally, she didn't get home until supper time, but there were few patients that day and the supervisor told her she could leave. It felt nice to arrive at the apartment in the late wintry afternoon when it was still light outside, and she was looking forward to relaxing and helping cook supper with her daughter.
The woman heard the television blaring as she unlocked the apartment door. She laid her coat over the back of a kitchen chair and noticed Kristy's high school books scattered around the table. It looked as if her daughter had been in the middle of some math homework and had been interrupted by something. The woman glanced into the living room and saw there was an afternoon space cartoon on TV, though no one was watching as she walked through wondering where her two kids were.
