Reason for the Possession tag?

Base +5, jklebonas +6, MikoPE +16

Possession or body swap; seems like someone swapped bodies with his sister and then swapped bodies with the brother. So his sister could be out there in some creep's body.

There's something exciting about the rough artwork.

Base +2, openminded20 +6

Wakamiya Santa's story is as incomprehensible as always. The art is good. But the story feels like some cheap excuse to have a situation.

It really is unclear I spent most of it trying to figure out if it was some kind of super pervert version of him or something but I think he and his sister swapped bodies and the sister is taking advantage of being able to force "her" body to do what she wants. That last line to me feels like its Mizuho saying to her embarassed brother she's going to live out all her wildest fantasy's. Could be his thoughts still though it does make a certain sister if the perverted sister swapped into his body at the same time he swapped into hers.

It's very unclear, but it feels like more toward another person took control of his sister body to masturbate, then later switch into his body to rape her.

@ Senkoau
No, the last line said "as Mizuho", in other words it was the thoughts of the brother inside of the sister. Rather it might be that his old body is just controlled by his own desires... which means that his little sister pretty much had her soul erased.
