Don't tell me Kashima waited for Sado to "finish" but it seems Sado end up sleeping on top of him instead.

this, in isolation, would look very wholesome
knowing that there is a loli under the cover that beat Kashima to it and that even grandma has her fill makes it far less

I am almost sure Sado just wanted to sleep, really.
So Kashima was soundly defeated by the innocent situation.

Sado didn't have sex with the admiral, Honshou did, but Sado wanted to sleep sleep with him, so Kashima sorta just accepted she wasn't getting any.
