(A/N: This has some kinda gross and super violent stuff involving mutilation, so I guess I figured I should just warn everyone. Don't like don't read and all that!)
Tyra considered what to do with them- should she drain them dry? Make them regular meals? Turn them to thralls or to other vampires maybe? But then she recalled how they'd treated her as a boy, and smiled evilly. Abusers like them didn't deserve to live, even to feed her.
She wished they would not awake no matter how painful they found her draining or how loud she was draining the others, and sneaked into her foster parents' room. She pulled the covers down until they sat around both June and Mark's shoulders, and climbed between them. Their heartbeats were thumping loudly, and she could practically sense the blood coursing round them, passing endlessly through the veins of their necks.
Baring her fangs and licking her lips, she bit into Mark's neck first and felt the warm blood flow out into her mouth, swallowing it as eagerly and greedily as someone drinking from an oasis in the desert. She drank in his scent as she ended his life- his pheromones were manly and thick, akin to the scent he had had before she turned herself into a girl. That gave her an idea that was somehow more disturbing, yet satisfying to her vampiric mind, than even the act of murdering Mark- she pulled the bedsheets all the way off and removed his underwear. The man's penis emerged, and she saw it was erect. For a second she wondered whether to go ahead with this idea, but the temptation was too great. She lowered her mouth onto his shaft and bit down harshly, allowing the phallus to fall from her mouth and sucking up the blood that flowed from its root. Her lower lips accidentally cut into his scrotum, and she tasted a mix of blood and semen that leaked from it which she found surprisingly agreeable. She smiled as she looked over Mark's destroyed manhood, a fun act of humiliation to go with her revenge.
Now Tyra moved to June, and brushed aside her hair before her fangs sank through the tender flesh of the woman's neck and reached the vein easily. She felt June's blood gush from her and flow into her mouth, lapping it up with her tongue and hearing the rapid heartbeat of the woman she was sucking on fade rapidly as she gave up all her blood to Tyra's fangs. Her scent was distinctly different to Mark's, and she noticed it seemed to compliment the scent from the man's crotch very well. Recalling that disgusting but deeply satisfying act, she pulled the covers down and used her sharp claws to tear through June's nightie. It fell aside as if her body had been unwrapped, and Tyra saw that her nipples were hard and erect. Did these two perverts get off on me killing them? she wondered. She certainly got off on seeing two aroused breasts, and so she decided to put her lips to one and suckled on the teat. Musing angrily on the fact June had never once let him do this as a baby and yet she had obviously allowed Dustin to, she decided to humiliate her foster mother as she had her foster father in death. Her claws hemmed around the flesh of June's breast and she tugged it off the woman's chest forcibly, lapping up the blood that flowed from where it had been and feeling an odd sort of catharsis. She then cut the other mound from her and sucked on its pooling blood, and as it started to dry up she pulled away. Before leaving June and Mark's bedroom, she smiled as she looked over her abusers' lifeless bodies, drained of blood and with their sexual organs cut from them.
Tyra made her way to Dustin's room, still slumbering and exuding more youthful pheromones and blood that she drank in eagerly, and again pulled the covers down to reveal his neck. But she hesitated for a moment. Not about doing this to Dustin, but about what to do to him exactly. Should she drain him dry like she did his parents, or would it be more fun to turn him? Or even turn him and change his sex as well as his species? After all, she knew how good that had felt.
After the moment passed, she decided to...
