Clean up is going to be particularly difficult, especially if you're sharing a bathroom. If your rooms are shared I would go so far as to say it's not worth the risk of possibly getting caught with (I'm assuming you don't really want him or anyone else to know you have an onahole as you're worried about sound). If your rooms are separate however, the sound will probably be less than that of you actually using your hand. While this depends on the amount of lube you're using, I've never heard much even when using a generous amount.
Hope that helps. Pic unrelated as well.
