Pour your “sour cream” into the girl, don't wipe it off, leave her naked, and end the night in that state.
I've come back!!!
I can't get the ninth ending for some reason??
It shows the tenth ending (the one you said but with the vibrator, I didn't even touched the vibrator?!)
How can I fix this?
You get the 9th ending when you buy the last upgrade and if you wake up the girl after a small insertion there will be the 9th ending
By the latest improvement, I mean "???"
