Glasses still on, she hikes her skirt and slides panties aside on the desk. “big buff” captures the surprise in her eyes when pleasure hits fast—fingers circling clit frantically. Books tumble as her hips buck in “big buff”, muffled moans growing until she comes hard, biting her lip to stay quiet while “big buff” records the flood of release soaking the wooden surface.
