No, but I have been playing with the scripting. 0 is off. 100 is fastest stroking. 10 is slow strokes. But these are not single stroke commands.
So, to make it a little more real, I put in 0 to start with. Then using joyfunscripter I put another 0 at the begining of motion, then a single move using side carrot key, then 100 then another single move and another 100 then a single move and a zero. This makes the Alex stroke only once. You could use 50 or 10 etc for the on value. But if you use a lower value than 40 you will need to include 2 moves before then next on value. Example, 0_20__20_0 for one slow stroke. A fast stroke would be 0_100_100_0. Now how to make this work, since strokes are typically faster than the action it represents. The best experience would be to put a quick stroke, 0_100_100_0 as she starts a down stroke, then at the dead bottom put another 0_100_100_0. Even though this give 2 strokes per one action, it seams real enough. Especially when she hits bottom and that 2nd stroke seems more like her hitting the bottom of your shaft, than a second stroke. I was surprised, very nice effect. Just repeat for every one of her actions. One quick at the top of her ride, and one quick as she hits your pubic bone as she rides. If she is going slow, then use the slow stroke values. Although using fast for even the slow riding, works just fine. You can play with it and see what you like.
