Ayame and Koga were in Koga's hoouse and he poked her in the wrong spot therefore she giggled. Then he thought to himself "Maby i could have fun with her". So he tells her to follow him, but when she does she gets smoked by sleep gas and falls asleep. When she wakes up she notices she has no socks or shoes on, her feet are in stocks, she's stripped down to her bra and panties, and her hands are tied to the legs of the chair. Then she know whats happening. "Koga is going to tickle me".
