That's just the thing. There is no "jerk it together". I only get to pay or not pay to watch. I've never seen an offer for cunni.
The cunni menu check is:
Relations["SluttyMaid"].allure.Value >= RelLevelsClass.AllureLevelHJ - 5 and SluttyMaid.MasturbatedTogether > 0
and
SluttyMaid.Fucked == 0 and SluttyMaid.Cunni > 0 and SluttyMaid.BlowJobs > 0 and Relations["SluttyMaid"].IsGirlfriend()
So allure of at least 50, have watched, have jerked it together (not the solo option), no fucking, go down once, have one blow job and have her as the girlfriend.
If you don't have a high enough relationship, it won't even get that far.
To be allowed to jerk it together, the check is
Relations["SluttyMaid"].opinion.GetPartExtrem() > 0.3 and Relations["SluttyMaid"].allure.Value >= RelLevelsClass.AllureLevelWatch and SluttyMaid.MasturbatedForYou > 0
So opinion of at least 30 and allure of at least 30 and you have to watch her solo act at least 1 time.
If you're not seeing Jerk It "if Relations["SluttyMaid"].opinion.GetPartExtrem() > 0.3 and Relations["SluttyMaid"].allure.Value >= RelLevelsClass.AllureLevelWatch and SluttyMaid.MasturbatedForYou > 0:" is failing, probably at allure barring any bugs.
if you don't have PDebug on, you'll have text telling your allure vs an actual number. You'll be "sexually "something. The breakdown is:
indifferent = below 10
appealing below 20
catching below 30
inviting below 40
interested below 50
attracted below 60
charmed below 70
fascinated below 80
desired below 90
longing 90 and above
If you've done all that and it's still flaking out, open the console (shift+o) and enter each line, pressing enter before entering the next:
SluttyMaid.MasturbatedTogether = 2
SluttyMaid.Cunni = 2
SluttyMaid.BlowJobs = 2
SluttyMaid.MasturbatedForYou = 2
Hit esc, and wait for the next time you catch her.
