Bro,
Sorry to ask. Are u that despo that night? And only that night only?
Ya, this is a very common trick. Say be GF, then cannot touch. But u kind heart. Otherwise, pls dun be taken in further.
Next thing u know, u will be ask to take her out on Transit so that she can re-enter here longer and "scam" on others.
Move on to other conquest. U will find ur money well-spent elsewhere.
