When Does the "Pay-Off" Begin for You?

By "pay-off," I mean the point in the chapter when the reader becomes
seriously aroused and starts thinking about fapping. For some readers,
it probably begins early when the girl's tits come out, and the guy starts
playing with her nipples. For others, it begins when she starts sucking
his cock. And for still others, it begins only when full penetration occurs.

Obviously, it depends entirely upon the reader's personal proclivities.
In my case, it tends to vary, but a hot set-up really turns me on, even
if it doesn't involve any physical contact between the characters at all.

For instance, one of my favorite chapters is Satsuki Imonet's mOTHER.
The first time I read it, the pay-off began early, on page five, when a hot
MILF catches a young guy with his cock in his hand. That turned me on
so fast that my own cock was in my hand by page six, even though the
MCs hadn't even touched each other yet. What a rush.

When does the pay-off begin for you?
What trips your trigger as you read?

It can be a simple gesture for me. Usually when the women is put in a position showing off her best features. Be it an upturn titty shot or a arch to the back showing off the leg/ass. Till than Im usually just reading around.

In my case I get really turned on by blowjobs. But I think I always start fapping when the girl starts getting into it, actually doing stuff on her own. This can go from her sucking the mc's dick voluntarily to riding him or simply stroking him, or just vocally expressing she likes it.
It can also happen, in chapters with bold girls that are actually trying to get the guy aroused so that they'll have sex, just as soon as her intentions are clear. So that would be the fastest I'd start fapping, I think.

That really turns me on when the girl squats
down and shlicks herself while sucking cock.

I totally get it, I don't even need the context. A good blowjob really turns me on.
Like:


I masturbated to this two without needing to read the chapter or any dialogue at all hahahahaha.

I recommend Let's Be Casual, by Kirihara Yuu. A great blowjob
scene begins on page 6, and page 9, panel 1, is unbelievably hot.
You'll start fapping immediately.

Tanks, will check!

I always read a story all the way thru before I decide if "That was hot. I'll reread it for enjoyment this time". Very few things are more frustrating and annoying to me than getting turned on by the action then the story goes south with my tastes and leaves me limp as a noodle. Also, good build-up and foreplay before the main event is a must for me. I don't like when the story has the participants going buckwild right from the start without some sort of background to what's going on.
