Having some toys in your arse, or in your partner's ass is a good thing. Or you could just get your anal whore girlfriend to wear a butt plug whole day long. You could get one with a remote vibration feature you know, when you can adjust the buzzing and intensity of an application on your phone, remotely pleasuring your girl. Possibly the best time to do that is when she is asking for a raise at HR or something, to get her in an uncomfortable position when they ask wtf is that buzzing. So yeah, a butt plug is cool, get one, it has a variety of uses!
