Joh If I translate your last sentence it means something else as you wanted to say or was is on purpose? Do you meant she is the last who needs be in a belt? If yes, I agree.
I assume she needs a belt less than pretty much all of the other girls that will be there. That is what I said. "She needs it least", not "she needs it at least".
I mean, she has negotiated to mostly control her belt-wearing schedule herself and still manages to voluntarily abstain from even the most harmless orgasms for months. If that is not a girl in control of her sex drive, I do not know what would be.
That said, I think it might still be a good idea to give her both the belt and a key for the trip if she wants to take part in the drinking. I am sure sober her is quite capable of avoiding temptation, I am more concerned about drunk her. Both in terms of impaired judgment, and because those holiday events are pretty much giant targets. An event full of drunk teen girls is the perfect opportunity for people who enjoy taking advantage of drunk teen girls. Not necessarily violently, but also simply stuff like being pushy and offering to pay for drinks in exchange for certain favors and all that.
So, if she already has a belt, she could just lock it on before hitting the bars at night, and leave the keys at her sleeping place or with one of her friends. Then she would be protected while being hit on and can still unlock the next day for all the chaste fun that such a holiday offers.
