I think we know what it's like to be skint and have no option but to go to work.
When one of my close friends was pregnant we did a 2 girl (she didn't declare to clients) she was mainly BJ and I was sex. I kept an eye and when she was tired I jumped in, when they tried to touch her bursting boobs I dived on them, if they even looked at her I rugby tackled them
could you not do something like this?
If not I second the camming/phone chat ect.
Hope you and baby are going great
