"Just try and stop me." he responded with a smirk. Watching his sister go down on him, he was already fully erect. The whole 9 inches. Apparently, her asshole was just brimming with cum, ready to lube her up for round two.
Sadly, their fun would be cut short. Because as he sat up, and she got on her hands and knees, they both saw something down the alleyway. A Ghostdog. Better known as a giant possum. They were the size of a Labrador, and for the most part behaved like one, but were actually mutated possums. And vicious things they were. If they were hungry enough, they'd try and eat you. Horny enough, they'd try and fuck you. Of course, most of them were killed on the spot, for food. Looks like this one was lucky, maybe someone's pet. Which meant it was more likely that Jesse and Hanna would get killed or fucked by the owner than the ghostdog. Either way, not the ideal situation.
The two siblings scrambled for their clothes, and once they were dressed, carefully shimmied along the wall as the ghostdog passed them and headed down the alley to find a snack. As they meshed into the crowd of other settlers, they became painfully aware of how much they smelled of garbage. It would have been extremely embarrassing, if anybody actually gave a shit about something like that.
The settlement they called home, named Turnpike, was the largest in the area. It was located somewhere in North America. To distinguish it any further would be pointless, everything's just desert nowadays. All settlements pretty much looked the same, just of varying size and status. This one was somewhere in the middle of the spectrum, on both counts.
Jesse and Hanna were in the town square, with the dusty walls of buildings (either leading down into cellars, up to apartments, or somewhere in between), enclosing them in a market area. This was the busiest part of the town, and it was a miracle that no one had found them but some rat-dog. They held hands so they couldn't lose each other.
"Jesse...?" Hanna looked at her brother, and he could tell exactly what she was thinking. He'd been thinking it too.
"I know sis, this is weird. But...good weird."
She smiled, and turned to look ahead. She bumped into someone (rather deliberately), and then pulled Jesse ahead and rushed out of the crowd. They stood near the wall of a hotel building, next to the stairs. Hanna held up a bag of cash.
"Why don't we find someplace quieter, to finish what we started?"
"Wow, you snatched that in one go? Nice." Jesse replied, truly impressed.
Hobos like themselves weren't usually allowed in markets, for this exact reason. Which is why they never had any money. But having had the luck of entering at night without ever being spotted, payment would now be easy to come by. Payment for absolutely anything they wanted.
