One of the rare moments you get to see Pierce blushing like crazy. xD

He really doesn't know what's going on. She's in an aroused moment and he isn't, so he doesn't get why she's fondling his wing. XD

Rose rather loves his wings, so of course she'll act sexual with them as well. :'3

Pierce will learn to like it in time. ahaha... and use it to his advantage. XD
