No ownership is allowed to me of one of my favorite anime series :/ So no Fullmetal Alchemist belongs to me.

Clarie slide off Al's back and winked.
"While you guys eat, I'm going to make myself something to eat and set up the blood packets."

Winry and Ed nodded, staring at the sleeping young man, while Al kissed her head. Winry turned to both the guys.
"Should I go first, like last time?"

Al nodded and removed his shirt as to keep blood from getting on it, while Ed winked at Winry, causing her to blush and look away.

Winry focused on Luke and spoke to the boys.
"Ready?"

The boys nodded as they let their insizers (I'm sorry but I don't seem to be able to spell that right lol) grow while Winry slid onto Luke's lap and spoke quietly.
"Luke… Wake up Luke."

Edward watched, amazed even after centuries, as Winry's ability to intrance humans were once again shown as Luke opened his eyes on her command.
"She's so strong, and she's mine…"

Luke blinked up at Winry, dazed still.
"Wha…"

But Lukes sentence was interrupted by Winry kissing him. The boys took this as the sign to bite and each boy took a wrist and bit down. Winry could feel Lukes silent shout before he lapsed into a coma like state.

Winry pulled away from his lips, her teeth growing while she turned his head and bit into his neck.

All three of them felt the endorphins kicking in. Ed couldn't help but slide his hand up Winrys thigh when she moaned. Her body tensed under his touch.

Edward slid his hand towards the inside of her thigh, earning another moan from Winry. He continued moving his hand up, playing with the hem of her shorts.

Right before Edwards hand slid up her shorts, all three of them heard a throat being cleared. One by one, they all leaned up to stare at Clarie with glowing red eyes. Clarie smiled warmly, completely at ease.
"If you guys continue, you're going to drain him dry."
