汁だく肉玩具姉弟 ～俺の触手で商品化～

I went to have fun, so why am I helping out at the event?
And now I'm cosplaying as a crossdresser...
"It feels like I've just wasted the whole day."

If it's like this, I should have stayed home.

I'll play some games to cheer myself up... Oh, this might be good. What's this...?
"Use tentacles to do naughty things to girls. You can also import and use your own images."

So if I import a photo of my big sister, I can see her getting teased.
