Laughter echoed through the cabin as Sakuya continued to slide her fingernails up and down Hikari's immobile soles. Though she was frantic, she didn't shriek or scream - she was capable only of soft giggles or melodic laughter, which were mixing together at the moment. Her most ticklish spot exposed and restricted to mere quivers was driving her mad, and that was only made worse by the fact that she couldn't see what was going to happen next.

It was because of this that the feeling of a hair brush with the round plastic balls on the teeth threw her for a loop. She arched her back as much as she could, which was only a few centimetres in her current bondage, and let loose a gasp followed by a higher pitched laugh. Sakuya loved this particular pitch, because it was more frantic, but she still wasn't screaming. "W-what is thahahahahat?!" Hikari struggled to say, but Sakuya didn't answer. She alternated what foot she tickled with the hair brush, while she reflected lovingly on the fact that regardless of how monotonous the action was, Hikari only became increasingly ticklish as opposed to becoming accustomed to the sensation.

"You're going to love this one, Hikari-chan~" Sakuya smiled, reaching for her favorite tool combination - two long feathers, one fluffy and the other stiff. Another gasp as the feathers chose their marks. "Feathers?! Please, not on my bare feet! Anywhere but the-ahahahahahahahaha! Nonononono! Pleahehehehese!" Sakuya used the fluffy feather to dust all over her soles, while using the stiff feather to focus on one spot at a time, alternating feet with both as she went. The fluffy feather teased in between Hikari's toes, which proved to be nearly as ticklish as her arches. Sakuya slid the tip of the stiff feather up and down Hikari's arches in a slow, cruel way, adding in quick strokes every so often to throw her off more.

Sakuya watched Hikari's soles quiver gently as she mercilessly feathered the pretty bare feet, drinking in the beautiful laughter and adorable pleading. She wondered how she could further enjoy tormenting her tickle toy, as she dusted her soft soles with the fluffy feather and focused on the balls of her feet and her toes with the stiff one. "Not my feheheheet! I can't...I can't..ahahahahahaha! Please! It t-tichehehehe! It tickles so muhahahaha much! Hahahahahahahaha!" Her laughter hit Sakuya's favorite pitch again when she ditched the fluffy feather for another stiff one, and used them to simply slide up and down Hikari's creamy arches and saw in between her captive toes.
