Your best holiday part 2

Tera set the assignment down and stepped out. Angel watched the door click shut. Nelly sat cross-legged in her pleated skirt, already restless. She leaned across the desk and ran two fingers along Angel's bare thigh. Angel tilted her chair back, legs parting. Nelly slid onto the floor between them, the cotton of her white panties brushing the tiles. She pressed her tongue flat against Angel's thin panties, wetting them through the lace. Angel sighed, opened wider. Nelly hooked the panties aside and licked straight up the slick seam. Angel's hips jerked once. Her breath caught, sharp. Fingers gripped Nelly's hair. Nelly sucked gently on the swollen clit, two fingers curling inside, knuckle-deep. The desk creaked. Paper fluttered to the floor, ignored. Angel came fast, quiet and hot, thighs clamping around Nelly's ears. Nelly pulled back, lips glossy, then climbed into Angel's lap. Their mouths met; Angel tasted herself on Nelly's tongue. Hands under skirts, panties stretched aside, they rocked together until Nelly trembled and bit Angel's shoulder, muffling a second moan. Tera's footsteps sounded in the hallway. Both girls froze, breathing hard, then laughed low and guilty. They straightened skirts, wiped mouths, and bent over their notebooks as the teacher returned.
