When she climax, her body and head are completely swapped/transformed.
After the Onee-san cums then she's used as a sex doll for a few days, but was soon squashed and left in a trash can in the back alley after being heavily sexually abused and used as a sandbag by the high school boys...
Of course, she was conscious, and she kept calling for help even after being thrown into a trash can.
The last pic is from the perspective of the soon to be sex doll Onee-san.

This is a "clean" re-upload; removed the original Japanese text and improved grandmar. I hate doing this, and I shouldn't have rushed posting shit until I make sure that it's actually worth posting.

Head Swapping should really, really have its own tag, yes.
