Checking in at the fertility clinic

The highway soon gave way to a main street, complete with shops, traffic, and pedestrians. The Millers got their first real taste of "free use culture" as they watched nude and scantily-dressed people going about their business... Most of which was fucking. Nearly all of the women were sporting at least some semen on their clothes and bodies, and every single street corner was the site of a brutal, almost frenzied gangbang.

"Look at them all," Francis murmured as he turned down a side street, heading for the waterfront. "Is the whole city like this?"

In the back seat, Jimmy gulped as he watched a woman with tits the size of her head walk down the street with her husband. Her chest was jiggling obscenely, and Jimmy wasn't the only one to take notice: a passing tourist soon grabbed her by the shoulder, pushed her down to her knees, then thrust his cock into her open mouth. After a few deep pumps he reached down and tore open her blouse, laughing all the while. The woman calmly accepted the **** until the tourist busted an impossibly-huge load all over her, while her husband just crossed his arms impatiently.

"...Uuum..." Jimmy let out a low moan. "...Guys, I think I'm getting hard again--"

All at once, every other member of the Miller family shouted some variation of "WAIT UNTIL WE GET THERE!"

"Okay, just..." Jimmy involuntarily ran his hand down one pant leg, which was beginning to bulge outward. "Hurry? Please?"

"Mhm, we're almost there," Francis sighed. "I don't have the hotel address yet, because we're supposed to check in at the 'Louise Piper Center.' I guess it's like a resource for tourists, and they'll send us to the hotel?"

His wife shrugged, glancing nervously at Jimmy's crotch. "That's fine, Dear, just do as he says and drive fast."

Half an hour later, Jimmy was sitting in a small, sterile-looking room inside the Louise Piper Center for Fertility & Breeding. The rest of the Miller family was just outside, getting the ins-and-outs of Salt Bay explained to them by a chipper young secretary. While their unusual circumstances slowly dawned on them, Jimmy was finally getting some relief.

It came in the form of a busty, plump-lipped nurse, who was slapping Jimmy's cock against her fake tits in a valiant effort to get him hard again. Lined up beside her were three plastic tubs, all nearly overflowing with her patient's semen.

"Ooh fuuuck, I feel them pulsing again," Jimmy groaned. Normally he would be ecstatic just after receiving his first handjob, blowjob, and titfuck, but at that moment he was still too concerned. "How can my balls STILL be full? Weren't your pills supposed to, I dunno, cancel out the ones my parents gave me?"

"Not really," the nurse replied with a shrug. "The pills I gave you should help relieve the pressure, but all that gooey, sticky, fertile spooge has to go somewhere!"

"Wait, why did you say 'fertile like thaaaaAAH! Shit!" Jimmy bit his lip as he unloaded yet again, shooting a few thick ropes of cum onto the nurse's tits and neck.

"Sssh... Just relax and let me milk you," she said soothingly, doing her best to scoop his latest load into a new container while still jacking him off.

"I... I just don't understand," Jimmy said wearily. "What is this place?

"It's a sperm bank, Cutie. Best in the OZ."

"Huh? That's..." Jimmy took a deep breath. "...Well, uh, I need to go. My family's waiting."

She gave a huff of disappointment before letting go of his cock. "You're the boss." With that, she collected the tubs of sperm and began to leave.

"Hey, wait. That stuff you said about 'OZs,' and Orphantowns... You weren't just fucking with me, right? Trying to get me off harder, or whatever?"

"Nope, it's all true," she chuckled. "You've entered a brave new world, and my friend is telling your parents all about it in the lobby. You're in for one hell of a good time."

"B-but, like, what should I do? Should I be giving my family orders, or running off on my own, or--"

"Up to you, Cutie," the nurse interrupted, squeezing her tits back into her uniform. "But come back if you ever feel like helping a poor, lonely woman conceive a child."

"Uh, is that what you're collecting all that sperm for?"

"Mhm... That too," she replied with a wink, before turning and walking out the door. The moment it shut behind her, Jimmy felt the tell-tale pulsing in his balls: he needed to unload, and fast.
