After a few more orgasms for both of them, Paul decided to pursue another one of his experiments. After all,
it was Friday night, and what better way to spend it than doing *ahem* science with his girl?
"So," he began cautiously, "so far tonight Big Paul's been here," he slipped a finger between her legs, "and
here," he kissed her with tongue, "but I was thinking maybe he could go... here," he removed his finger from
her cunt and slid it down to rest on her asshole.
"You're insatiable!"
"Just the way you like me."
"That's true." She gave his proposition a bit of thought. "Okay, but be careful. I don't know if I can take
something that big down there." Well, Paul thought, we might not find that out.
Sure enough, he watched as his cock began to shrink. It settled in at somewhere between 5 and 6 inches long,
and a bit thinner than average. In fact, it looked like almost exactly Paul's natural size. He was bemused
to discover that all along he'd been Liz's ideal size for anal.
The anal sex was good too. Liz took him without much trouble, and was plenty tight. He came after 5 minutes
or so. She didn't.
Paul was a bit disappointed by the rather dull results of his last experiment. An average-sized cock was
practically the null hypothesis. So he moved onto his next experiment.
"Thanks. Let me make it up to you. Here," he scooted over to sit up on the side of the bed, "come sit in my
lap." She grinned, and Paul felt his cock swelling larger again (it was easy to feel once he knew what to
feel for). Oops, she had the wrong idea. "Facing the same way as me."
"Oh, okay," she said, a bit confused. She sat down him, his cock between her lower back and his belly. Her
confusion cleared as Paul slipped both his arms around her, using one to tweak her nipples and the other to
rub her snatch.
Paul liked this position for giving hand jobs. He had good access to her whole front, there was lots of skin-
to-skin contact between his front and her back, and he even got a bit of a thrill out of pretending that he
was feeling his own ladyparts up.
Paul wasn't as good with his hands as he was with his mouth, or maybe Liz just didn't react as well to that
kind of stimulation, but Paul's arms were getting quite tired by the time twenty minutes later when Liz arched
her back against him, squeezed her vag around his fingers, and shuddered through her fifth or sixth orgasm
that night.
She turned her head and reached it back to kiss him as the last few contractions went through her. "Thanks.
But for future reference, your lap isn't terribly comfortable. It has this big pokey thing coming out of it."
She wiggled her butt against the base of his hard shaft. "But I think I know how I can fix that."
Paul carefully watched her next move, eager to see if his plan was coming off right. She got up off him,
turned around, straddled him, knelt on his legs, and brought her hands to his big cock. Good old reliable Liz
had done just as expected. Paul had known that if he gave her a hand job, she'd be sure to return the favor.
So now he'd get to see what size she liked for hand jobs.
He watched, rapt, as his cock grew in her hands. It had started out even with his bellybutton, and was
quickly ascending past the rest of his abs. As it grew in length, it swelled in girth. Liz had to shift her
grip several times. It stopped as thick around as a Nalgene and with its orange-sized head nestling up
against his sternum.
Paul nearly creamed at the size of his gigantic cock. Eight inches had seemed huge, and he now looked to be
about twice that. He moaned at the realization that he almost certainly had the biggest cock on the planet.
Liz managed to encircle it with her two hands, but not easily; with her thumbs touching her pinkies didn't.
There was plenty of room for Paul's own hands, so he reached down to help out.
The addition of Paul's hands shifted his mighty tower a bit away from his body and towards Liz's, and its head
brushed up against the underside of her breasts. Almost immediately, Paul felt his cock swelling in his
hands. He watched in shock as it stretched up even longer, pushing its way between Liz's ample breasts. Paul
thought to himself that while Liz was somewhat modest when it came to most of her fantasies, when his cock
wasn't going to be inside her she was quite the size queen.
Liz pressed her upper arms against her tits, pushed them tight around Paul's cock. In addition to the four
hands working his shaft, he was now also getting a tit fuck. Wait, three hands on his shaft. Paul looked
down from his cockhead and Liz's bouncing boobs just in time to see Liz begin to fondle his balls. She had to
go one at a time, because they were now the size of softballs.
Liz followed his gaze downwards, and saw the giant purple head of Paul's cock sticking out of her cleavage.
She stuck her tongue out towards it, and barely managed to lick some of the precum flowing out of its gaping
slit. But it seemed that subconsciously she wasn't satisfied with barely reaching, as Paul's cock again
renewed its ascent.
She began licking it more and more easily as it rose towards her lips. There was no way it would fit in her
mouth; it was the size of a grapefruit or small melon. But she licked with reckless abandon. The tiny part
of Paul's mind that wasn't entirely focused on the pleasure he was receiving appreciated the skill Liz was
demonstrating in simultaneously licking his head, stroking his shaft, and fondling his balls all while
squeezing her tits around him.
By now the tip of Paul's cock was just past Liz's lips, giving her an excellent position to suck his frenulum.
His shaft was by now coated in the precum whose flow continually increased, and as big around a coffee can.
At its base rested two melon-sized balls, forced up onto Paul's thighs since there wasn't nearly room between
his legs for them. Paul licked his lips at the sight.
Then he realized that in addition to being at just the right height for Liz's mouth, it was also hovering in
front of his (the boost she got from sitting on his thighs made their upper bodies about the same length). He
leaned forward to smear his own mouth and tongue over his monstrous cock.
That was the last straw. There was no way he could stand having two mouths, four hands, and two tits all
pleasuring him for long. He cried out a warning, felt his balls contract and his cock swell, and then gushed
like a firehose. The first shot rained back down on them. The second through fifth hit the ceiling. Paul
lost count as his orgasm seemed to stretch on forever. Liz tried to take one shot in her mouth, but it
overwhelmed her and cum drooled out between her lips. She grabbed Paul's mouth and stuck it over his slit so
he could try himself, but he fared no better. He noticed that his cum tasted delicious, sweet and tangy.
Another thing to thank Liz for.
After Paul had coated Liz, himself, and the immediate area in a liter or two of spunk, his orgasm finally
began to subside. The three of them -- Paul's cock deserved counting now -- collapsed down onto the bed to
recover. Gradually Paul's cock softened and shrank, but it remained superhuman. Later he would measure it at
eighteen inches long and eleven around, flaccid.
"So," Liz asked, "did I finally manage to satisfy Paulzilla?"
