Wake him up in the night for sex

A woman can always seduce a man subtly if she puts her mind to it. So see what happens if you press your buttocks up against him in the night, or if you press your hot vulva against his cock as he slumbers. Move your hips around a little as you do this, and he'll soon be raring to go. This might be best reserved for the nights you don't have an early start next day.
