Gifts for mom and dad?

I bought lingerie online to wear for my boyfriend and dad saw the package come... opps! He doesn't know what it was but now him and my mom think I was ordering something for them, so needless to say I need ideas on what could be the "gift" I was getting them. Any ideas are appreciated, thanks! p.s. I'm 19 so i'm old enough to have bought it butttt I don't need them to know about it.
