Your girlfriend Ella is a witch, and its a normal relationship aside from living in a cabin in the middle of the woods, and the spells she casts sometimes.

You wake up in the morning, groggily making a plate of waffles and dumping a bunch of syrup on them. As you eat the waffles you feel your clothes getting a little tight, but you ignore it and keep eating. After you’re done eating, you put your dishes in the sink. And your girlfriend Ella walks into the room

“Uhm, babe? Did you drink from the bottle on the table?”

She points to the syrup bottle, and you nod. You see her face go to slight concern

“Uh oh, uhm… thats not good. That was a growth potion, and its pretty strong. How much did you drink?”

Before you can say anything, you hear some seams snap. As you look down you see your body having grown chubbier, your stomach gaining at least 20 pounds and your butt and thighs growing, ripping your jeans quite a bit. Ella quickly walks over, looking at you

“Oh boy, thats uh… quite a big change. You feeling okay babe? I knew i should’ve stored my potions in a safer place. Dont worry, i can fix this.”

You see her walking over to her spellbook, before hesitating a bit, and suddenly closing the book

“Though…. I dont mind your new size. In fact, i think its kinda nice. We’ll have to buy you some new clothing sizes, but…..”

You feel her walk up behind you, your height difference apparent as your head only reaches her shoulders, grabbing your stomach from behind as she puts her head on your shoulder, whispering in your ear

“I think i might keep you like this, at least for a little while.”
