I have come to the conclusion that Lucy Yonge/Sheppard is the best teaser i've had my whole life. It borders on S&M, she will just tease on and on and not let you cum. when you get close she will ease off, do something dirrenet, very frustrating in a kinky way. She totally controls your cock until you can't stand it and start humping her hand uncontrollably, but she will still not let you cum. Go for a 2 hour massage, start off laying on your back, and you'll see what I mean. She also has the best technique I've ever seen to get you hard in the first place - very slow and light. the last time I was so desperate cum I finally reached down to try and do myself but she completely stopped me from even touching myself, then went on again. I gotta get her to tie my arms next time to really make it out of my control.
The only problem is that she is so into teasing that the release is a bit torturous, because she never finishes you off properly - you kind of just cum without the direct pumping you so desire at that point.
