I admit that Caroline has curious reactions but this girl is really ticklish. Girls are not robots, they're all differents and sometimes we find girls with very particular laugh. Tickling is a particular fetish who generate sometimes particular reactions. DLKR has really understood the situation when he says that her reaction is way to helpless and desperate to be staged.
It is impossible to fake continuously like this. All of us have seen faking girls in tickling videos but is there anybody who have ever seen anything like this before ?
