It was always a matter of trust. His tongue licked Sirius's neck clean, his body pressed skin against bared skin together in comfort and in trust. Biting someone, taking their blood, was always a sexual act for Lorcan. Penetrating flesh, and taking from it pleasure. There was no other way to see it. And the small whimper, sent an enticing shiver down his spine. "I'll never let it hurt," he said in a reassuring murmur.
He stepped back a mere step, allowing himself room to prop himself up onto the arm rest, his legs dangling of the floor. He hooked his heels behind Sirius's hips and tugged him forward.
Lorcan was growing harder, each squeeze and stroke of his length caused his breaths to quicken and his face to start to flush for a brief moment. His hand came to rest behind Sirius's neck, squeezing the back of his neck and encouraging him to shift his attention to his hardness.
"Oh gods. That mouth," he said between heated breaths. "Please."
