Hi guys, can anyone recall one of these 2 stories:

1) She comes on some tropical island to check on some agricultural research and realize that almost everyone is going naked around. With time she also starts to adept to new situation. It is more parts story. Can recall that at some point female colleague of hers from company also visits and is surprised how uninhibited she became

2) Guy sells the audio equipment to a couple, and once he gets invited to install it at their place, he ends up having sex with her while husband is watching (maybe its even 3way, can't recall anymore)
