With the small hit of oxy in his system, Liam actually feels it. That involuntary buzz of pleasure as Mike wraps his lips around his thumb. A crackle that goes up his arm and down to his groin. Involuntary and pleasant. The drug always disconnected his mind from his body, so his own thinking wasn't dulling the sensation. Which was why he brought the hitter to his lips again, drawing in a deeper lungful this time. He wanted to feel what came next deeper than anything he'd done to Mike before.

Head thrown back, he slowly exhaled. He looked utterly satisfied as if the drug were some form of nourishment seeping into him. Slowly, he rolled his head back and down, eyes half closed, just enjoying the twin sensations of the high and of Mike's lips.

"Do want another one, Mikey?" He let his stretch out, sounding almost lazy, making no indication what he might mean. Especially since his fingers curled beneath the other's chin, pushing his thumb a little deeper.
