Here's a series of fun panels that featuring a boob swap between a popular girl and her geeky roommate.

I love the relationship dynamics in this, where the cute geek girl is so enthusiastic about the temporary swap and seems very reluctant to giving her big boobs back to her roommate. Also love her slim and stacked look. It would have been great to see a before pic of the geek girl for comparison.
It's so fun to see how much she enjoys showing off her new assets on the internet, as if they are hers.
