edit The "real surprise" method
This method is very close to the regular, real life surprise. You will approach your target and proceed have sex with them, and this person will be very surprised, almost not noticing your act upon them.
Find a nice person of your likings. Try to avoid them noticing you - a good tip here is to change underwear (ask your mum how to do this) and take a shower.
