Chapter Text
It'd been too easy getting Osomatsu to eat the slice of cake you'd brought him. You batted your eyes and told him just how hard you'd worked on the tiny dessert (a lie), and in seconds it'd been crammed into his mouth. You smirked and wiped away a bit of frosting on his cheek, making him grin like an idiot.
"So, how was it?" you asked sweetly.
He opened his mouth to respond, but all that came out was a choked gasp. It was hard not to smile, watching him shrink down. You were excited that your secret ingredient worked so well.
You leaned down to pick up the tiny stumbling boy, placing him in your palm and prodding at him. His dazed swatting at your fingers did nothing but make you giggle.
It took only a few more seconds before his vision stopped swimming and he was glaring at you.
"What was that for anyway!? I haven't even done any-" you cut him off by licking up the front of his body. When you pulled back, his face was bright red and he was shivering.
You weren’t all that surprised by the unpleasant flavor.
"You taste terrible, you know that?" you said as you headed towards their kitchen. Your eyes brightened when you saw a mostly empty pastry filling bag sitting on the counter. "This should help, don't you think?"
Before he could respond you squeezed a bit of the cream into his face, making him sputter.
You tasted him again, letting your tongue linger just a bit longer as smooth vanilla coated the inside of your mouth.
"Much better. Alright then, thanks for the snack, Oso!"
He yelled as you buried him in the sugary filling, head popping out only to immediately be greeted by your gaping mouth. You tossed him inside without a second thought and curled your tongue around his tiny body. The cream had done its job and masked the sweaty flavor you'd tasted earlier, making it easy to tilt your head back and let him slide towards the back of your mouth.
His surprised shout was cut off by you swallowing, and a second gulp had him slipping completely into your throat. You felt the squirming warmth all the way to your stomach, and sighed in pleasure.
Now he was just a comfortable, angry weight in your gut. His shouting was barely audible and quickly became background noise. You looked over to the five color-coded confectionary boxes you'd brought with you and kicked the sixth empty one aside.
Shouldn't be too long now before the others get home.
