Secret masturbation

Steph

So I have a vibrator and I use it during sex with my husband. Well we work a lot and are on different sleep schedule so a lot of times when I want it he is sleeping....he knows I use my vibrator when he isn’t here but I’ve never masturbated using my vibrator with him home. He is sleeping now and I’m so horny but I’m scared he will wake up and catch me lol what do I do? Is it bad that he knows but I don’t want him to catch me doing it?
