Is all playing done in private or is there an opportunity to watch others or be watched if you choose?

Both is available...provided there are others out in public. Last time I was there, I had the pleasure of watching 2 guys work this sweet blonde over. Amazing in every way!

i had sex with this cute german blonde in the cinema room. im sure others were watching

- it is often where sessions start - with BJ on the couches - before moving to a room.  However, some will stay in the Kino for the whole session.  Although I have only been to Oase in early spring I understand that in summer the action moves outside to the chaise lounges around the pool and to some tents.  Also I have observed some amount of intimacy in the whirlpools and saunas and on the couches in the main rooms.  Also when really crowded during the big trade shows rooms get scarce and any alcove is put to use.  Just thinking about it makes me wish for a German trip.

I'd report back after Tuesday, but I won't get to Oase until about 10-11 pm.
