Black hair grazing skin during a deep lick

Late night in the dimly lit apartment, the air is thick with tension between them. One girl decides she can't wait any longer to taste her partner's heat. She pulls her friend close, eyes fluttering shut as she presses her face into those soft folds. The moment her tongue first makes contact with the sensitive skin, a sharp gasp escapes. She focuses on licking deep and slow, swirling her tongue around the entrance until the other girl starts arching her back in pure, breathless ecstasy.
