It’s been established that eating the hearts of supernaturals gives you their power, so what about blood giving you a temporary power boost? Anyways Tsukasa biting into Hanakos neck, drinking his brothers sweet blood and growing stronger so Hanako can’t push him away...

Imagine Tsukasa grabbing Hanako’s hair, yanking it to expose his milky white neck, running his tongue over his brothers pulse (assuming supernaturals have pulses) before sinking his fangs in and biting. Hard. Hanako starts squirming and thrashing at the pain but Tsukasa

holds him tight, licking the wound and relishing in the taste of his dear brothers blood. He drinks until the spurts stop coming, yanking Hanako’s head to the other side. His brother starts begging for him to stop, voice choking off into a broken wail as Tsukasa digs his teeth

into the flesh of the other side of his neck. He laps and sucks as the wound, growing stronger and stronger as he takes in more of his brother. He’s been reduced to quiet sobs and whimpers, body growing limp and sluggish from Tsukasa draining his power and blood. The flow

eventually slows and Tsukasa gathers a mouthful, finally meeting his brothers watery, glazed eyes. He digs his thumbs into his brothers mouth, meeting little resistance, opening his jaw as he leans forward, sealing their lips together and letting Amane taste his precious blood

End of thread! Inspired by @tsukasascummies beautiful post and then my mind going... ‘but what if it’s blood?’
