Gave this a try, but I twisted it around a bit, instead of going pure sexual escalating from the get go, I made them sexual qualify themselves first, and then escalating into sex topics, made it looked like it was their idea and I'm just playing along.
Landed a HB8 wing woman for now (she said she doesn't have sex with stranger while emailing me paragraphs long describing her sexual experience lol), and a HB7.5 (who agreed to meet me at the mall and try public sex

) so far, 3 others got hooked still in process of getting to meet up.
Vic was right, this is indeed a quick way to pick up girls strictly for sex, save a lot of time.
There are some stuffs I noticed that will help:
- Girls with normal profile > girls with slutty pictures
- If you qualify them a bit before escalate, you get more success with higher quality girls (>7)
- Don't lower your standard and go for 4,5. They tend to be too insecure to express their sexuality and less likely to get hooked for NSA. You will have to waste a lot more time with them than 7 or 8.
- I opened with a vague sexual qualifier "what is the most adventurous thing you have done for a guy?". If they say something romantically, I tease them, and they will qualify again -> most of the time they will switch to sexual experiences to impress you. If they go straight for sexual answer, I just sexual escalate right away.
