Have To Behave

You're going on a night out with your housemate who you've recently fooled around with, but your girlfriend is also coming out. Essie is worried she might figure something is going on between you two, and she doesn't want you breaking up with your girlfriend cause it was just some stupid fun. So you need to behave tonight! But you can't be trusted and Essie thinks it's a good idea to get a wank out of your system now while she teases you with her sheer panties!
