If it kept up this way, he'd end up fucking the whole family. Except Emma's mother, of course. But why of course? Jack remembered that Emma's mother was a damned good-looking woman. Why not fuck her, too, he fantasized, and make it a clean sweep?
First things first. Right now he had a sexy, naked young woman playing with his rigid cock. Why not let her beat him off?
"You ever see the sperm come out the end?" he hissed.
Sue shook her head, her eyes big.
"Just keep working on the fucking thing like that… It'll go off like a time bomb!"
"But then you won't be able to fuck me!" Sue blurted out in alarm, jerking her hands away from Jack's swollen rod.
"The hell I won't!" Jack shot back. "I'll just reload the damned thing. That's all!"
Sue's eyes got even bigger. What a thrill it would be to keep jerking on Jack's big beautiful cock until it spouted hot sperm for her! The very thought gave her a feeling of intense sexual power. Her hands returned to the big man's prick. She started pumping again, watching the loose outer skin slide up and down the hardness inside.
The tip of Jack's cock was slowly turning purple. She watched the blood pound into the slowly swelling knob. She began searching for refinements in her technique. She found when she stroked her thumb up the sensitive underside of Jack's knob, the big man moaned with pleasure. Her other hand cradled his balls, wondering at the soft feel of the hairy, wrinkled sac.
"Ooohhhhhh, Christ… yeah… just keep on stroking the mother-fucker that way," Jack panted. "She's gonna blow soon…"
Sue suddenly saw a gleam at the tip of Jack's cock. A single shining drop of pre-cum had worked its way to the surface. It welled up in the slotted tip, a glittering liquid jewel, clear as glass. Sue watched it, fascinated. Her thumb rose to smear it over the head of Jack's cock. It was incredibly slippery, helping her fingers glide over the swollen knob.
"Uuuunnngghhhh!" Jack moaned.
The slipperiness made Sue's hands feel even better against his throbbing prick. His hips shoved upward, as if he were trying to drive his aching cock into an invisible pussy. He was close to cumming.
Although she had never seen a man cum, Sue guessed what was happening. Her face flushed with excitement as she speeded up her handwork. Jack's cock began to swell larger and larger.
Then the eager girl saw Jack's balls suck up towards his body. His big cock began to spasm and jerk in her hands.
"Oh, Jeez!" Jack blurted out. "It's here! I'm gonna… gonna CUM!"
Jack's hands balled into fists. His back arched powerfully, his legs jerking and twitching. Sue felt the big tube on the underside of his cock shudder and swell. There was a rushing feeling. A shining gob of sperm shot out the tip of his cock, arced through the air and landed on her left tit. It was hot.
Another jet, then another. Jack's cock was spouting like a new oil well, spewing its hot load of sperm into the air, most of it spattering stickily onto Sue's naked body. The cum on her left tit slowly ran down onto the nipple, hung there for a moment, then dripped stickily down onto her belly, a long whitening thread.
Sue didn't mind the cum spraying over her at all. She was too fascinated by the hot feel of Jack's cock jerking and spouting as she eagerly jacked him off. At the sight of his hot jizz gushing out. There was so much!
Then, the most amazing thing of all. Jack's huge cock began to shrink, turning rubbery inside her clutching fingers. In a couple of minutes it had shrunk incredibly, a harmless little sausage dripping sticky strings of cum. Sue laughed delightedly. It was all so incredible!
Jack lay panting, sexually wrung out for the moment. But the sight of the happy, excited naked teen-ager kneeling next to him on the bed revived his flagging interest. But not his cock. It flopped limply onto his thigh when Sue finally let go.
"Come on down here," Jack ordered gruffly, pulling the girl down next to him on the bed. Her skin felt incredibly smooth and alive against his own. Her big solid tits pushed firmly against him, inviting attention.
Jack rolled over and started licking Sue's tits. "Oh!" she gasped, surprised at how good it felt. Jack's tongue was hot against her nipples, making them throb with pleasure. Her cunt began to ache, demanding attention of its own.
It wasn't long in coming. Jack's hand groped down over Sue's flat little belly, heading for her crotch. Her flossy pussy hair was like silk. His fingers slid downward, seeking out the girl's virgin cunt.
Sue's pussy-slit opened up easily. The girl was so turned-on, his finger had to wade through puddles of hot girl-juice. Sue's hips jerked upward as soon as she felt Jack's fingers inside her pussy-slit. It felt so exciting, even better than when Emma had fingered her pussy the first time!
Jack slowly explored the girl's untried cunt. So fucking smooth! Everything so tight and new! She sure had a well-developed clit, though. Jack's fingertip began teasing Sue's hard little love-bud. He had no way of knowing about the long hours of frantic masturbation that made her clit a force to be reckoned with.
"Ooooooohhhhh!" Sue whimpered.
A warm burst of gratitude gushed from her heart. What a wonderful thing her big sister had done for her – lent her own boy friend to give her young sister her very first fuck. To make sure it was a good one!
But when was he going to do it? Sue's pussy-hole fluttered with excitement, eager to be filled.
"Please… please… fuck me!" Sue moaned.
"Jesus… you do have hot pants!" Jack panted. "Didn't you ever hear about foreplay? You're gonna get the whole works!"
Besides, his cock was still a limp ruin. About as much chance of stuffing it up Sue's tight twat as there was of stuffing a wet noodle up a wildcat's ass.
Jack's forefinger tested Sue's cunt-mouth. "Mmmmnnnnn," she moaned happily as an inch or two slid smoothly up into the tight opening. But as his finger thickened, it ran into the stout defenses of the girl's still-intact hymen. Jesus! It was a tough one!
Jack started worming his finger around up inside Sue's cunt, trying to open her up, trying to stretch her maidenhead a little. It worked, to a degree. But when he shoved a second finger in beside the first, he felt the girl flinch. Sue felt her first warning of pain.
"Oh, watch out," she faltered.
Jack could tell he had a lot of work ahead of him. But what pleasant work! He moved down so that he was staring straight up Sue's naked crotch. He watched his two fingers chug slowly in and out of her pussy-hole.
What a sweet little gash! Jack ran his eyes eagerly up and down the full length of the girl's slit. So fucking clean and pink! Just right for a tonguing!
"Hang on, baby," he grunted. "You're in for a ride!"
Sue was having her first doubts. Jack's joined fingers felt impossibly big up inside her untried cunt. Together, they stretched her hymen enough so that it hurt – sharp little twinges of warning. She remembered how much bigger his fully erect cock was. Incredible that it could ever fit up inside her snug little twat!
Then Sue forgot everything else as Jack's mouth ground down against her cunt. His strong hot tongue lanced up into her pussy-slit, aiming straight at her clit.
"Aaaaahhhh!" the girl choked out.
The most incredible ecstasy she'd experienced since first experimenting with sex ripped wildly through her hotly mouthed cunt. Had she wasted her time masturbating? she foggily asked herself as Jack's tongue danced up and down the full length of her steaming pussy-slit.
Jack soon found he had a tiger by the tail. Sue started bucking wildly. She proved to be a lot stronger than her tender little body intimated. He thought his neck was going to break as Sue's hips jerked repeatedly upwards. Her legs clamped desperately around his neck, making his ears hurt. He thought he was going to smother in hot wet cunt-flesh before he finally freed his nose, gratefully drawing gulps of air in through his nostrils.
