Trapped - Diabolik Lovers X Male Reader
Sora's life couldn't get any worst. he is currently trapped in a mansion, in a laboratory room that is always locked tightly. Sora being an "experiment rat" for Karlheinz, a vampire that needs Sora's blood. you see... Sora is quite special, his blood is bitter sweet, and the taste of it is amazing, it's a strawberry flavored one. and because of that Karl is afraid of letting his sons find out about Sora's existence, cos they would drain him from drinking too much blood, so he keeps it a secret. but what happens when they "accidentally" find out about it?
