I was checking out naked pictures of the Carlson twins one day, and then decided to share it with Housemate #1 so that she could check them out too.

A few weeks later, Housemate #2 is on Housemate #1's computer and sees the naked picture...

Housemate #2 asks in a curious tone: "What's THAT huh?" (They have known each other since they were like 5 years old.) 

Housemate #1 quickly brushes it off by saying: "It's NOTHING, that's just something that someone sent to me..."

Housemate #2: "SURE that's just something someone sent to you huh..."

When Housemate #1 told me about this, we both agreed that Housemate #2 probably thought that she was a horny slut that needed to download material to masturbate to, and then would get all embarassed when she was caught.
