I did have clients (from sugar baby arrangements rather than escorts) offering me "opportunities" to work for them (as in non-sexual work) so this can definitely happen, I wouldn't say any of them were life changing, I have just seen them as results of non conventional working, but they told me about them while we were meeting as usual, I wouldn't go for anyone who tries to bend the rules of the previously agreed arrangement we have in place.. If he was genuine about it he would've told you during one of your bookings I think.
