hows about you have a shower and you "fall down the stairs" (ie stomp down them and lay at bottom) in your towel will they come help you will they see anything , who will come see!
or you could wait till your sister is watching a movie and go ask her to come look at something on your computer then go get a shower and u might be changing wen she walks in to see this thing on your comp and see you naked or you might be dressed.
you could "borrow" something from her wen she at school that you know she will need then be changing wen she comes home and u may be naked wen she comes in to your room looking for it.
for your mum you could walk downstairs in just your boxers with huge hard on and go make breakfast and u might see her you might not she might see your hard on she might not!
naked with just dressing goun on but left open would also work!
what bout answering the door in just your white socks one day no matter who it is! but lock the door so ur mum or sis would have to nock or it could just be the mail man
