“Hot smoker, just like yer daddy,” Biff said, and pushed some smoke in Nathan’s direction. It…smelled different, coming from him. Hotter, somehow, and he blew some of it back, his hand slipping back down to his crotch, thinking about how horny he always got, trading smoke with his daddy like a couple of perverts. Biff noticed, but didn’t say anything, just kept pushing smoke in his direction, watching Nathan slowly lose focus, groping himself more and more, his hand slipping into his still damp khakis to stroke himself properly. He finished his second cigarette, and came back to himself for a bit, pulling his hand away, but he only lasted half an hour before asking daddy for another.
“Sorry boy. Ya want another cigarette from me, you’re gonna have to shoot a load. That, or ya gotta give me some good road head.”
The idea of getting anywhere near Biff’s cock horrified him, and he wasn’t about to jack off again…but he needed a cigarette. Biff kept pushing smoke in his direction, and it was maddening, and hot and sexy, and his hand slipped back down. What harm was there in…one little cum shot? It wasn’t so bad, right? Biff kept sending him smoke, and watched him give in, stroking faster now, until after a couple of minutes he shot again, and just like before, Nathan went slack, eyes glazed over and mouth hanging open.
“Emptied yerself out again, Nate?”
“Yes daddy…” he muttered.
Biff took the next exit off the highway into a small town, “Good, I was gettin’ hungry. Let’s get us both filled back up, eh?”
There was a fast food joint right by the off ramp, and he pulled into the drive through, and the guy taking the order thought it was a joke at first, Biff ordered so much food. It took a little while to get everything, but before too long, they were parked, with bags and bags of burgers and fries–with plenty of soda to wash it down. Biff pulled out a burger and put it to Nate’s mouth. “Go on Nate–feed that big ol’ gut a yers.” Nate mindlessly took a bite, chewing slowly and swallowing. Biff grabbed one of his slack hands and put it on the burger to hold it. “Faster boy. Ya eat like a fuckin’ pig. Don’t care how messy ya get, ya just need it in ya.”
Nate started eating faster now, and Biff kept encouraging him, reminding him to take plenty of drinks of soda–after all, he loved soft drinks, and anything sweet. He was hungry, always hungry, even hungrier than his dad, usually. Hell, he was fatter than his dad was even–he could remember how proud he was the day his gut sagged down even lower than his dad’s did, couldn’t he? Nate kept trying to agree, but his mouth was too busy shoveling in food for any of it to be intelligible. He ate and ate, his gut expanding at a rapid pace as he did, the buttons on his shirt popping off one by one, the undershirt riding up as his gut dropped between his thighs, his pants stretched to the limit as he grew larger and larger. He became more animated, slowly, Nathan coming back to the fore as he filled himself back up, but he didn’t stop eating–he couldn’t stop eating, sucking down his soda, and sucking down on his cigarette, of course. He was such a good son, cumming for his daddy, and now he got his reward–another smoke, and a massive fast food meal to boot! It wasn’t until he finished most of the food off–his dad having eaten a sizable portion as well, that he leaned back, let off a belch, and realized just how much bigger he’d become–and realized that they’d stopped moving.
Nathan fumbled with the door handle, and nearly fell out of the van. As he did, he felt a massive shudder in his fat as his khakis, and underwear, finally burst from the pressure, and he was left standing in the parking lot, in full view of the people in the restaurant, naked from the waist down, a massive, hairy apron hanging free…and he didn’t know what to do. He needed to get help, but not like this. He couldn’t possibly let anyone see him like this!
“Son, git yer fat ass back in the damn van!” Biff shouted at him, and Nathan struggled to resist.
“You…you aren’t my dad! This…this can’t be real, I’m just imagining this. I can’t…actually be this big,” he muttered, hefting his gut and letting it fall, feeling it thwack against his thick thighs. “I mean…I eat lots, but…but not like this.”
“Boy, git back in the van.”
“No. No, I’m not…going anywhere else with you.”
Biff sighed, “Boy, git back in the van, and we’ll go ‘round again ‘n git ya some shakes. Ya are still hungry, ain’t ya? One a every flavor–enough tah git ya home.”
HIs gut rumbled like an earthquake, and his mouth watered, thinking about it. Fuck, he was…hungry. So hungry, even though he’d just eaten so much food, he could barely believe it was still inside him. “But…but I…”
“Son, what ya think’s gonna happen when those folk call the cops on ya? Think Master’s gonna be happy when he’s gotta bail yer fat ass outta jail? Probably just leave ya in there with ‘em, ‘n make ya some jailbitch. Now git in the car, ‘n let’s git dessert.”
He was right–there was nothing he could do looking like this–without even any clothes to wear. That…and dessert sounded really damn good. He got back in, surprised by how hard it was maneuvering his huge bulk, and Biff drove him back through, ordering a shake in every flavor as promised–twelve in total–and then headed back for the highway while Nathan sucked down shake after shake, and cigarette after cigarette to go with them. He managed well enough for the rest of the ride at least–though Biff kept ripping off the worst farts Nathan had ever smelled in his life, laughing after every one he made, and refusing to roll the windows down. Thankfully the food made him sleepy, and not too long after finishing the last shake, he passed out for a while, snoring and belching away, Biff reaching over to grope his boy’s massive fat belly occasionally, and then drove into the city, arriving at the small apartment complex where he lived not too long after that, in the evening.
