I like the idea, but I feel like it would be a bit different.
I feel like what would leave her blitzed out for a week is that she was able to be naked in front of so many people and she’s just very very much about that.
but what I REALLY think is, that Tracer is a bit of a… hmm how to say that… like she doesn’t have a praise kink; she has kind of the opposite? she wants to others to be a bit mean to her. to pinch her small, pointy tits and the meager fat on her thighs. Maybe slap her and tug her around on her hair, make her not have a choice because they push her down and sit down on her face and suffocate her.
She needs that kind of attention (or the not-attention when they use her like an appliance)
so I think what Emily would gift her for her B-Day is her getting dominated by all their lady friends. Just ruthlessly used for a whole evening until she’s a teary snotty mess
