Looks like we've stumbled upon Yukiko as she's being adventurous with her sexual fantasies. Judging by her secret stash under her bed, she's been having very specific kinds of fantasies, and now that the 12" Deep-Drive she mail ordered has arrived... she's gathering up courage to try it for the first time.

(Note: This takes place in an alternate timeline from the Midnight Channel pics I recently did. Her butt here is untouched.)
