TWOE-002 Comic Market Cosplayer 2: Seriously Trying to Pick Up Yumi (pseudonym)

I secretly took some photos of a cosplayer at Comic Market!! Yumi-chan naively followed me when I asked if I could do a private photoshoot after Comic Market. She looked tired from Comic Market, so I gave her a massage!! It started as a serious massage and gradually turned into a naughty massage... Despite her appearance, she seemed timid, and just kept giving me pleading looks at the camera, letting me go all the way to the end...
