I knew a blonde with the most intagram worthy ass I have ever seen at the gymnazium. Its definitely mostly hormones, which they get from the pill. Anticonception. There are multiple kinds of anticonception pills if you ever talk to a girl about it, and this girl was on the strongest one since very, very young. Probably the reason why she had such a giant, perfectly shaped, firm ass. damn. She was also a complete psycho whore with giant body count and someone probably molested her when she was young
