My sister cums while holding a mantis in pleasure from her first cunnilingus! ! I have a super shy and shy older sister, but I recently got a boyfriend and it's been strange... 1

My super shy and shy sister recently got a boyfriend, and just as she got a shocking request from her sister, "I want you to lick her pussy!" ? He was so embarrassed that he refused to give his boyfriend cunnilingus, but it seems he's about time to refuse... so it seems he'd like to try cunnilingus first and get used to it. When I gave in to my sister's desperate request and licked her pussy...it felt so bad that she cumd so much that she held her head down with a mantis between her legs! In the end, she couldn't hold it in and turned into such a lewd woman that she wanted to put on a dick!
