Chapter Text
The first time it happened was in Purgatory.
Dean had all but collapsed against the nearest tree, blade tucked against his chest, and Benny watched as Castiel ran a quick ward around the area. The angel was full of surprises, and he wasn't as weak as he tried to make himself appear to be.
Benny was sitting against a tree, watching the angel curiously, and trying to ignore the way the angel's heart pounded in his chest, mineral-rich elixir pumping just beneath the skin. The smell of the angel had long since overwhelmed Dean's normal humanity, and Benny was aching for a taste.
Just one taste.
It had happened suddenly. Castiel had paused between them, looking fondly at where Dean lay asleep, and then he was crossing the space to Benny with determined strides, straddling him and landing heavy in his lap and Benny fought the urge to groan when the angel grabbed his jaw and tilted his head up for a desperate, hungry kiss. He could taste the blood rushing to Castiel's lips as capillaries broke beneath the skin, giving them that rosy, kiss-bruised look, and the heady rush of warm blood threatened to send him sky-high.
Arousal coiled in his stomach, but Benny wasn't alive enough for a hard-on, not yet. He hadn't had a decent meal in decades, but that didn't stop Castiel. He guided Benny's hands underneath the worn trenchcoat and beneath the well-stained scrubs.
"Please," Castiel murmured into his lips. "Touch me."
Understanding clicked in his mind and Benny surged up, pinning Castiel to the rough forest floor. He shoved the once-white top up to bunch under Castiel's arms, lavishing the lightly tanned skin revealed with all the worshipful attention it deserved.
Castiel was alone, and so very tired of it. Benny knew exactly how he felt. His hands were rough against Castiel, trying to push through the skin so the fiery creature beneath could feel it.
It was a scrape. Just a scrape from the fall onto the ground, but Benny found it and curled his tongue around it. He felt Castiel's groan through his chest though no sound came from his throat, felt the angel's insistent erection against his stomach.
Benny slid down his body, wrapping both hands around Castiel's slim hips, thumbs brushing over hipbones, and Castiel's head slammed into the ground when Benny wrapped his mouth around the heated flesh. The taste of blood rushing, just beneath the surface of the skin, and Benny was lost, so very very lost.
He was lost when Castiel laid a hand on the back of his head, a hand that he should've been able to break with a touch, but laid heavy like tempered steel. Castiel's hips bucked up, fucking roughly into his mouth, hand holding him steady.
It was never like that again, but Benny never forgot the power that coiled just under Castiel's skin.
