Руководство по тому, как говорить непристойности девушке в постели, сделанное для фотографов и видеооператоров.

If you don't know what to say, try asking sexy questions. 
Ask 
'shall I pull your macro lever towards my mount?' 
or 
'do you like it when my lens hood is locked for shipping?' 
This is a great way to include your partner in the dirty talk, as asking questions will draw them into a conversation.
