The date's on! But will you screw it up? Let's see shall we?

Gadzooks man, look! You've only gone and charmed Michelle's top off. Get in...

Whoa! What now? Do you A) Explain you invited her over to break the news you're her long lost brother? or B) Maybe mention it later?

Oh no, has your adventure ended? Michelle doesn't need another mouth to feed. Back to your adoptive parents.

Or is it a raging success! You are having sex with Michelle and she's loving it! Although things might get a bit complicated if she gets pregnant.
