Building on a thread I read on a different theme, using reverse psychology to close with a mark is a lot easier if they are drunk. I would class this as a late night bar play, best used on an isolated target.

Open using S P A (Style, Personality, Attitude)

"me: [SPA move], but I get your awefull in bed.
her: What!??.. rubbish..
me: [refer to SPA move]... so... i imagine you just lay there..
her: not at all.. im brilliant in bed..
me: Id take you home, but I know you will just lie on my bed looking like a manikin (makes funny corpse pose).
her: (laughs).. dont think so.."

The play needs to evolve into letting her think she is in control of you, you ask very closed questions so that the answers tend to stay sexual. Use this to your advantage and build up an aurora of mystery about how you are in bed so she wants to find out.

remember, you're already talking about sex openly at this point, no worries.

example:
" me: so whats your favourite position?
her: doggy style.
me: why is that? (getting details about what she likes, making her think about sex)
her: feels good when being done from behind "

this is just one, but there are many potential questions, be creative! BUT remember, don't get pushy and ask too much, you'll end up with a walk, if the mark is drunk they'll be more chatty about sex remember to keep it light, loose and fun, don't get creepy.

if anyone else can think of good follow up questions add them on!
