If I could fly, I'd like a convenient pair of black wings like Dark in DNAngel that I can hide and show at will. I'd choose a scenic afternoon, then I'd take my girlfriend behind the clouds and fuck her wild while enjoying a scenic sunset.
I thought but decided that it would suck if my wings burnt everything (I like my clothes) and having wings made of fire would be too noticeable for me so i'd go with without aid.
I'd fly without aid. Then I'd go on the freeway and knock on car doors and then fly away before they notice me and have me on the news and then get chased by the government and then get used to do spying and then make money and then fly to japan and then buy doujins at comiket.
