Violet was fixated on Nina's hand. She was drooling slightly but didn't notice right away. Her thighs flexed together continuously, desperate for attention to her own pussy.  She twisted her hair in her fingers, biting her lip. As Nina started begging them to watch her cum, she couldn't take it anymore and began rubbing her own pussy through her boxers, although trying to be as subtle about it as possible, she figured the other girls may just think she's trying to keep her hand warm between her thighs, as delusional as that sounded to her.
