I'm not sure if splitting work into odd/even chapters was a good choice...
Sequential chapter dumps would be less confusing, even if we had to wait.
Thanks for the chapter.
This isn't just a depiction of ryona.
There's a niche fetish in japanese eromanga depicting "womb punching", where burly men make girls orgasm by repeatedly hitting them in the lower abdomen with full force.
Just FYI.
