I think you should aim for my belly button. Make it deep. Every time it hits, my ribs expand and and my belly sucks in and out. Having my hands tied over my head makes it a very vulnerable experience and with each hit (from the invisible and painless shots), I get more and more aroused till I and cannot take any more.
