Meh...
Pretty fun game. I suggest for the third game that you make it so that you have to "go down" on a girl. Perhaps for the final stage, the player has to "please" Lady Kar (aka you?). Neways, still found the game to be a bit too hard. You do test out the game yourself, right? Remember, if the creator can't beat it, it's probably too hard!
Neways... some tips... I guess... (I've only used Sora -_-;. Tenderness and force, but only cause that's what I'd like from a girl...)
1) Meh... first guy... standard stuff. Should be easy to beat. Just don't stop. Get some air only when your constitution's low. Don't wait until your constitution bar's full! Get back in there almost right away! If you don't get $2000, I suggest you choose a secondary stat after this client. I went with force.
2) See the lump in the middle? Stay in that area.
3) Second lump from the tip. As in, just past the middle.
4) Go for that area just past the U shape (aka, past the ring). Aftewards, try for a third stat.
5 & 6) The middle part...
7) Uh... good luck!!! I'd try just past the gap near the tip, but...
