Sanae is a good girl, so she'll let herself be tied up by anyone she's friends with, so it's better to do that than try to take her by surprise. Her outfit allows for a good view of her hair, but also hides her nice legs and hips, though her chest is the nicest of all. Tie her in a position to allow for a full view of her front but also with her arms above her head to expose her nice and ticklish armpits. Use a thick gag to emphasize her eyes by covering her face and touch all of her nice spots to get her to squirm and moan cutely. Time is never wasted by kidnapping Sanae.
