It's awesome. It's a complete nerve sensation overload. You can almost feel your mind going off like little fireworks. And all over your body. And when you cum.... well... thats like saving the best and biggest firework of all!
As also a Ler (I'm both Ler and lee.) I guess besides the obvious (IT"S HOT.) Um.... there's something about "forcing" someone to cum to tickling that... it's like... you're making someone acutely aware of so many nerves in the body.... making them "spazz out" and causing them to not be able to think... just to laugh (insanely...) it just makes sense to connect it all to a mind blowing orgasm. It's like puting two live wires together. =)
