Erotical Night - Great JRPG style game with an interesting sex combat system, first to orgasm loses (using items is very important).
Peach's Untold Tale Flash game that's been in development for a long time and has come so far. A Mario style game where instead of losing lives for hitting enemies, you have to get them off, increasing Peach's sluttiness, and hindering her movement when she gets too cumfilled.
