Crimson and sweet, the bond of the three. Betrayed by her lover and charged with a crime she did not commit, Rosa chooses to end her life by casting herself into the river. She survives this, and wakes up in a mysterious garden where she is met by two vampire girls — Calen and Trill. They ask her to join their cause and let them drink her blood, to which the woman agrees. However, drinking blood turns out not to be such a simple task. Something is needed. That something is s*xual arousal… And so, Rosa’s days of her body being developed in the hands of the girls begin.
