"Aww, Roll, please...." Rodrigo whined, taking off the butt armor to expose his bum bum.

(Is Rodrigo in armor already?)

"Alright, since we don't have anything to sit on, my knee will have to do." said Roll as she sat down on one knee, the other going up. Then she carefully guided Rodrigo to bend over it, one of her arms grabbing him by the back to keep him steady and locked.

(I'd say so. After all, Megaman X was already in armor, though the base armor of the game in the game's story.

Probably it was for X to survive the 30 years on the capsule, this theory could help here. After all, Rodrigo was fully upgraded and was operational, while Roll needed to have a new body built for her.)

Rodrigo looked pleadingly at Roll!

(Alright, I was just imagining he also had a casual mode where he looked more like a normal boy)

"That trick won't work on me." said Roll as she raised her hand and let it fall across Rodrigo's bottom with a loud SMACK!

(If he has, maybe Roll would help him know that. She does have more memories of that time, so if Dr Light mentioned it to her, maybe she'll know a button or something to activate the casual mode.)

"OWWWWWW! Big siiiiiiis!" Rodrigo whined!

But Roll ignored his pleadings as she proceeded to deliver several more smacks to his bum bum.

"Oww, owwie, oww, Roll, please!" whined the poor boy.

"Not until I'm sure you won't ever do something like that!" she scolded, spanking the butt more and more.

"Owwie, oww, ouch, but, but...." Rodrigo whined, sniffling.

"Yes, your butt will be quite sore by the end of this!" Roll scolded as she focused more of her smacks on the cheecks.
