Despite sluts are possibly diseased, it doesn't stop me from fucking them. All I have to do is put on a rubber. If they're ugly, no brown paper bag or rubber. The hot sluts are always a SILFs.

"SILF" is an acronym for "Sister I'd Love to Fuck", which means someone's sister who'd you like to have sex with.
Boy #1: Gosh- Lily's sister is such a silf!
Boy #2: They are both silfs dude!
Girl #1: You guys are both right! They are silfs.
Boy #2: They are both silfs dude!
Girl #1: You guys are both right! They are silfs.
