You realize that you've been thinking about this wrong the whole time! Why bother trying to sleep with women when it's clearly hopeless? Instead you should just build an Invisibility-Ray and spy on girls in the shower. (perv) If it works in anime, then it can work for you to! (I don't think that kinda thing works out too well for anime characters most times...) Shut up.
You get busy in The Lab, which is actually just your garage but you call it The Lab, and are rewarded with the creation of an Invisibility-Ray! It's a ray that makes you invisible. (duh) You test the Invisibility-Ray out on some of your furniture.
"Great, it works!" You say, then you take a step forward and stub your toe on an invisible sofa. That might have been a bit of a mistake, but no time to fix it now, you have girls to perv on! You stub your toe on several more invisible pieces of furniture as you leave your house.
You drive out to the local high school, Barely Legal High School, which is in fact the only high school in the country where all of the students are over 21 years of age but all look like they're 16-18. You put on a large felt costume of a hooker, the mascot of BLHS is the Inner City Hooker, crowds love her during school football games. The poor boy who has to wear the thing claims to loves her slightly less, though most of the male students who are made to wear it for disciplinary reasons are secretly into that sort of thing.
You use the Hooker mascot costume to sneak into the locker room/showers right before cheer practice ends. You question why you hadn't just turned invisible before sneaking onto the school. On closer inspection of the costume you found several suspicious stains.
