Yeah not my thing. I want my intimate time to be mine and no interruptions. Being caught would just annoy me because it'd delay the ending.
We got away with it while at Excellence with no issues at all. We never saw any security on the beach. I'm sure it may be dif at TTR though with the overall higher level of adult shenanigans that we hear about!
For us it's both! Sex is always a good thing and the excitement of people watching or catching us can be fun!
