Paul woke, without a start, a few minutes before his alarm was due to go off. Pleased at not having to be awakened by an awful beeping, he reached over and switched off the alarm. He spent his extra few minutes before he was due to get up languoring under the covers, idly stretching and stroking all over his body. He had some vague recollection of a dream he'd had... something about a child? No, not a child... a midget? In any case, it was gone now. As his clock ticked incessantly onward, he reluctantly got out of bed and prepared for work.
That was Monday morning. He didn't see Liz again until Wednesday evening. They went out for dinner, then went back to her place to watch some TV and cuddle. After the show they started making out on the couch, as usual, and soon they decided it was time to move to the bedroom.
Paul led the way, with Liz close behind. In fact as soon as she shut the door behind them, she pressed herself against Paul from behind, her arms stroking his torso. Paul purred appreciatively. Soon enough one of her hands dipped below the waist and cupped Paul's crotch. "And how is Little Paulie doing?" she asked playfully.
"I think he wants to get out of these pants. And into yours." Paul reached back and grabbed Liz's pert bum. She let out a surprised squeak.
"Well, we can get the first part of that done at least." She began unbuttoning his fly. "I doubt you'd fit into these jeans though; they aren't that stretchy."
"Har har, my little joker." Liz had his pants around his ankles by now, and he dutifully stepped out of them, then turned to face her. "So now that you've checked in on my boy, I think it's about time we checked in on your girls." He reached up her shirt to grab her C-cup breasts over the bra.
They continued undressing each other, and moved onto the bed. Probably to frustrate him a little, Liz let Paul undress her completely while his dick still strained against his boxer-briefs. "Alright, I suppose it's time we let Little Paulie come out to play" she said from her position below him. Then she pulled down his boxer-briefs as far as she could reach, as Paul lifted his knees one at a time to get them through.
As Paul fumbled with his feet trying to kick his underwear all the way off, Liz cooed "Ooh, it looks like Big Paul is happy to see me." What? thought Paul, did she just call my junk 'Big Paul'? He looked down.
"Holy shit my cock is huge!"
"And you're a paragon of modesty," quipped Liz wryly, "what else is new?"
Suddenly it all came back to him. The shooting star, the wish, the visit from Priapus in the night. Was it all real? Rationally he knew it was still more likely that he was dreaming now, but, he figured, if it is a dream, he may as well play along and enjoy it.
"Yes, Big Paul is indeed happy to see you." And he was. Fully erect, he looked half-again as long as he'd ever been, and proportionally thicker.
"Well, let's not keep him waiting then." She grabbed his cock and guided its head to her waiting hole. That was all the invitation Paul needed. He thrust into her. "Ouch, slow down, you know you need to work it in gently." His thrust stopped short with just a few inches inside her. There was still more cock outside her than Paul had ever had before.
Paul almost came right then. Partially at the simple fact that he had to be gentle or he'd hurt people with his huge cock. Partially because his brain just began processing the way Liz's cunt was gripping him. Previously her cunt had always seemed delightfully warm and slippery, and stimulating when she squeezed him or when he was thrusting really hard but now... God. Her cunt was gripping him harder than he did to masturbate!
Liz grabbed his butt and gave a gentle pull, reminding him that he still had a lot more cock to get inside her. He gradually slid himself further and further in, and they both began quietly moaning. She'd never gotten this turned on this quickly by sex before. Neither had he.
He continued sliding in, centimeter by centimeter. It seemed to last hours, and did last a few minutes. Finally, his hips met hers at precisely the same moment Big Paul reached firmer resistance. Liz shuddered and grunted, sending a wave of contraction down her pussy. It was too much for Paul. He cried out, and came.
It was a good orgasm, needless to say. Long, too. In a small back corner of his mind Paul figured that he must have bigger balls now too that produced more come, and that come took noticeably longer to travel down his longer hose.
Paul took a few moments to gather himself after he finished, then said "Sorry, I meant to keep Big Paul waiting a little longer than that."
"Don't worry about it." She kissed him. "Just clean it up and start again."
