Would probably not work. I never seen or experienced an instance where a little rapport wasn't required. They have to "feel" it with you first... even if it's brief, and you're just being playful, sarcastic, etc. Don't care how good looking you are. I knew people who were (and I myself was) very good looking - gorgeous, even - and pushing too hard for physical never worked... even when they came up to YOU.
Some guys were all about banging girls - many of them - but it didn't work like this. One way or another, you HAD to talk and get a little acquainted. Even if it's just casual / fly-by ****, or when you hang out prior to getting sexual, or if you're even texting, or bumping into them again.
If you're very attractive, they'll show strong signs of interest once you get the ball rolling - in addition to approaching you, talking about sex, etc.. So, it's still very easy, but not like this. Most of the time, they'll invite you into their space, and get close to you... not you going in.
But hypothetically speaking - making out with a stranger isn't the same as having sex with an acquaintance. So, this technique is **** regardless. Better to get acquainted, having them show interest, checking you out while in their presence, talking sexual, maybe playing the game a little, building up some anticipation, then bang like no tomorrow.
