Nothing to really complain about.
Except for the length in time in which an orgasm occurs for both of the sex's. =\
I can understand sense it's a flash game no one is really gonna care but upping the time by at least 100% would be allot less silly. =D
Also to add on to your girlfriends idea for lactation add a pair of hands
to that and a couple different animations.
This game already has allot put into it so simply adding those things wouldn't be hard at all.
I think making tifas love juice a little more noticeable such as going down the leg or something wouldn't hurt either.
Simply adding those would give the game allot more life.
You would probably get a daily 1st instead of a 5th. lol
