Don't feel bad, she loves it! She's just being bashful~

Anyone know any other similar doujins where a mesugaki shows a backstory where they were naive but taken advantage of by a geezer?

Base +9, 64DOOD +6, GoldLance +6, Clever_username_ +6

Poor mesugaki, she was looking for empathy and instead triggered the geezer into going bolder.
