She's bound up & at her captor's mercy... & did you notice that rope biting into her clam? Ow! That smarts! Of course, if rope were just little looser ... & if she moved back & forth just little ... she might get rope to play along her clit & stimulate it, & give her some kind of thrills. very tight rope wouldn not have enough play in it, however little slack in tying & she could have herself fine time with rope rubbing her little clitty just right. Sweet, wouldn not that be?
