Seung Mina is a gal who will draw attention to herself by the amount of skin her outfit exposes, but her skills with her naginata make it not easy to take her by force. On the plus side, she's friendly enough to become willing to be tied after a spending a bit of time with her. Use rope or something to hike up her outfit to expose as much leg as possible, not to feel them but to have as much access to skin for Foam as possible. As nice as her chest is to look at, she doesn't like it touched, so focus on her other squeezable areas to get her squirming and bouncing. Adjust the gag based on if her hair is braided or down, though something like a ballgag or microfoam tape works well in both cases.
