Frogtied and straddling a padded horse, Maggie struggles to escape the ropes holding her arms. She knows it's hopeless, and that her situation is only going to get worse. With her pierced nipples exposed, they make for an easy target. It only takes a moment and her breasts are pulled forward by the twine looped around her nipples. Each struggle or squirm only rubs the coarse twine against her nipples. Not quite painful, but not pleasant either. The tickling is the worst for her, as her body involuntarily jerks and pulls hard on the twine.
