Identify Looking for old-ish pixel art game where the girl progressively undresses as you play minigames

[zerracas]

I'm looking for this hentai game, or series of games, where you play some varied mini-games with a girl and then you choose some of her body parts to grope, or undress. The girl is not from planet Earth, I think. I distinctly remember this one minigame where you had her sit on top of a balloon and there's a banana under it... or something like that. Can anyone shine some light on this?
