Dilemma to

I think it's working, walking around with very few clothes on and very tight clothes, walked past the room the other day and I heard him saying*** yes*** yes, I know I should know make the move on him, but when would be the best situation to do it, we always have a movie night on Saturdays maybe that's the time to do it, I have some nice sexy underwear and a short nighty, it's not unusual for me to go down and watch the film in my nighty, but not one as short as the one I think I'll wait, anyone that reads this has any idea what I should do? I'm open to all suggestions
