Hm, I did two break-in stories and they are both here. Sexy Tales #01 has a break-in into a school dormitory and Sexy Tales #08 has one where the rapist breaks into a manor owned by the victim.
Also, I'm writing another break-in story.
They are fun because it's cool to surprise the victim, like grabbing her from behind or having her wake up from sedation close to be raped.
Break-ins are always fun to write, specially if you know the layout of the place you're working with. I develop my own layouts in regards to houses and places, although some I take from residence planning sites and house rental sites.
