Hehe, having your gainer partner do the driving on a road trip, ordering them when to stop for food. You’ll lean over their protruding belly to bark off menu items they’ll be eating, can’t help but feel them shift their legs together as it keeps coming.
You’ll be sat in the passenger seat unwrapping and feeding them every little food in the over stuffed bag, the small one is for you since you can’t keep much down on a bumpy road. One hand rubbing their growing belly, shifting a little when they feel the steering wheel start digging into them while trying to drive still.
At the first rest stop you two hit, they’re stuck in the driver seat. Top of their belly is distended and shining red while the rest of their belly sags between their chubby legs. Looking up at you with a begging puppy look in their eyes, they ask that you lower the seat and help them slide out. You wrap an arm as far around their waist as you could and help them to the passenger seat where they can finally recline and digest.
Getting back onto the road, and a grumble sounds off from the passenger while they snore away. You’re pulling into a drive through again before they crack their eyes open. Waking up by the time you grab the first bag from the window and plop it on their lap and they dig in immediately, not even noticing the two others you put in the back seat.
Those three bags were enough to nearly send them back off to sleep but those damn bumps in the road are just dislodging burp after burp in them, you can see a bit of nausea in their face but you tell them to hold on as you’re just around the corner from the house
