Just up XX.
She's very vulnerable to licking.
Hint: Suck her clit a little and flick with tongue and she will make some grunting sounds and can even twitch a little.
Generally good sex but not exactly spontaneous. She seems more distracted by the sound of a few guys having some conversation outside. Quite turn off to be honest.
LL nicer to foreplay, XX nicer to lick. Sex wise with them... ok la. Prefer to up LL as she is more "innocent looking" and her pussy responds more during fucking.
