He led her to a space where there were hooks on the ground in various spots and wood rafters about seven feet from the floor. She couldn’t reach them without jumping, but Snape could do so relatively easily. "Stand here. Feet apart, arms out to each side." She did exactly what he had asked, and he retrieved a long length of rope, measuring it with his hands until he found the halfway point. When he did, he looped it around the back of her neck, causing her eyes to widen with apprehension, but he simply smiled and twisted the rope several times before bringing the ends down and through her legs. He then separated the two strands, bringing them around her thighs and hooking through the rope at the front before returning to cross at her back and come back around to catch the next twist in the rope down her middle. She gasped as the rope tightened with each pass, creating an intricate symmetrical pattern over her dress that felt tight and firm. He continued the pattern until he tied the ends off at the loop below her neck, and then he looked down to admire his handiwork. He pulled the fabric of her dress upwards at the hem so that her cunt was bare, and then he shifted the fabric at her breasts to expose both. She mewled at the contact with the cool air; the ropes constricting her breasts caused them to bulge tightly between the coils of rope and she ached for him to touch her.
