Verbal topics are usually not covert. Chicks expect guys to slip sex into the chat, usually well before it's appropriate (where she feels that it is appropriate and for us - well before attraction and trust have been established).
That said, the easiest way to bring up blow jobs is to slide into sexual topics via dating, relationships, romance chat. That's the typical way for most beginner PUAs.
Covert? She's not aware of it? Or rather she can't readily identify it?
So in my experience, covert stuff is
Eye contact
- When you look at her i.e. timing - She says/does X - you break the normal pattern of interaction and stare at her.
- Intensity - You look at her like you're gonna devour her, while you make small talk
- Duration/repetition - Maintaining eye contact, looking at it often
- Let her see you look at her mouth.
Physical touch
- Depending on the setting, but you can set the tone with kissing cheeks at the beginning, or a hug. That's more cultural than anything.
- Dancing, obviously
- Leading her through a crowd by holding her hand
- Guiding her through the crowd by pushing on the small of her back
Facial Expressions that are reactions - my personal favorite and possibly strongest thing in my arsenal
She say something and you just look at her, she says "what", then it dawns on her.
"It was a really big one"
Then I go into a look of surprise, look her down, shake my head - and she'll put together what I think she said in her head.
Now if she goes for the bait, I usually have a two way angle.
Her - "X is not what I meant"
Me - "I didn't say anything, but I meant Y. Where is your mind?" (accusing tone) - Escalates, and my "hands" remain clean.
The way I look at game, it's almost always happening on a few levels.
- The verbal and obvious level - where most guys play their game.
- The subtext of the conversation - where she's reading between the lines, trying to interpret what I say, put her best foot forward, trying to control how I see her. This is where most girls end up playing their game.
- The frame level - Through my actions or inactions or reactions, I'm controlling the flow of the interaction - I have the frame, she answers to me, dances to my tunes.
I do this ALL THE TIME. Online and offline. It keeps the interaction spicy, and she's not really sure where I'm going to go.
But
Paradigm Shift - Why Hide It? Why pretend that you're not sexual?
Meat Market and Archetypes and Frames -If you've been lifting, know how to show off your hard work, the environment is sexually charged, AND you've accepted your inherent and natural sexual being - you can talk about sex easily.
Chicks will push back hard, if you do not look and most importantly
BEHAVE the part.
So the rock star, the patchouli stinking hippy, frat boy, college jock/gym rat, and dominant business guy type - can pull this off.
They pull it off, because they not only pass alpha tests, they flip it back on the chick.
But if you don't have a strong visual identity like that - and you're just discount clothes trying to pua ninja your way into some pussy - it's much harder.
Frame Alone
Still, a lot of seducers don't look like the archetype - but they're so solid in their frame, so open, so unshakeable, that they can do it easily.
David Bond is an example of a guy that does not look like a lady killer at all - maybe a fit IT guy - and he's running his game quite well.
His harem experiment is operating on a different level, but within that he's got a rock solid frame.
