Seducing My Vampire Master ～ Cold Vampire Lord x Maid、Lustful Night Driven by Instinct～

Count Stirling is determined to live his eternal life in solitude... But his new maid, Raven, is equally determined—: she is desperate to be turned into a vampire.
When Stirling attempts to scare his persistent maid away, the power dynamic shifts from dismissal to a smoldering, forbidden attraction. No one thought this would result in a night of intense, unbridled passion where master and maid push each other to the breaking point, proving that sometimes, the most dangerous cravings are the ones we can't resist.
