Dunno about the rest of you but the "taboo" part of games like this is only about 50% of the turn on. For me carrying this story forward to when they return home and then playing through all the sneaking around trying to not get caught would be what really clinches the attraction.
Palmer I think that's why I enjoyed your first game so much, as that was a very present part of the story. Parents down stairs fighting while the kids are getting closer, mom outside the bathroom door while they shower together, and the hints that the parents suspect what's going on and then try to separate them. That whole story element is what drives me nuts (in a good way) and i'd like to see it more in your games again. or any game really.
Example idea's you or anyone else are more than welcome to use/modify.
- Picnic with the family and the cousins are "wrestling" when she finally pins him and he realizes she's got no panties under her dress...
- family road trip where they're in the back of the van watching a movie together and playfully petting, each day going a little farther.
- camping trip where one sneaks to the others tent, and/or both sneak away to skinny dip but then the parents (or another set of cousins/siblings in love) wake up with the same idea....
- weekend trip the family goes tubing/kayaking and the lovers get separated down a different river branch and catch a few moments alone but the rest of the family is trying to find them...
- "baby sitting" the cousins and getting playful in the blanket fort while mom's making dinner
- Playing hide and seek and getting intimate while other cousins/sibs are looking... getting away with it makes you bolder so you try more each time... maybe you get found out but can you convince them to stay quiet?
- eventually maybe it's found out and the family separates you, how do you over come that? do you have a sibling/cousin/friend that is enabling you? helping you but with ulterior motives?
- eventually going to college and people know you're related, getting intimate in classrooms/chapels/library/artroom (mmmm painting and sex)/photo studio dark room (not just the cliche studio)/bio lab etc.
anyway that's where i'm at with all this stuff. Thoughts? is this just a me thing or is the trying not to get caught part a turn on for others.
