Dressed in a hurry

*All characters in this are over 18*

You're Joe, tall, blonde, blue eyed and reasonably good looking with a pretty athletic body. You're good looking and you have everything going for you except... The size of your penis.

You wake up and through bleary eyes you see the time on your alarm clock: 7:30, it's the first day of your final school year and you're late.

Jumping out of bed you find everything except clean underwear, in a panic you run down stairs to the laundry room only to find nothing of your own, but there is a pair of your twin sister's pink satin panties, with black frilled edges and a large black bow.

Surely just going commando would be the sensible option?
