its like that girl in the background is just cheering for you to beat off.

Did you not fail to realize she’s also like six sizes bigger now. It’s well known that girls breasts are the first thing to enlarge when their stomach does. She’s just one of those curvy girls that probably had to starve herself and work her ass off to get into playboy, which cut down on the tits. Or she could have the rare problem of a chest that won’t stop growing, which usually starts during puberty and requires reductions every 5-10 years.
