Hand injury but mega horny...help!!

So I have a hand injury and my man is away for a week and my libido is crazy high- can't focus and function. What are some ways I can get off without hand? Considered getting a vibrator but worried parents may find the packet. (Visiting them for a week while he's away). Humping a pillow doesn't really help. Also don't have a shower head and need clitoral to get off.
