Firt time with girl (virgin girl)? It's so, thats normal.. the "ahegao climax" started at second times (also is possible with first time, just play a little more with movements).
Open the cheat menu (ctrl+x) and see if some parameters at bottom-right is some number as 4/4, 14/14 (don't remember), those parameters means the "ahegao climax" on girl.
EDIT: 05/01/25
Here a screenshot as sample, look at the right bottom corner for the parameters.
