The arousal he felt from their joining was intensified, magnified almost beyond comprehension as Sirius moved, every thrust carrying him higher and higher toward an elusive peak. He clung to Sirius, fingers tensing on the damp skin of his lover's back, his legs locked around Sirius' hips.
"Yes, want you so much, Liebling," he moaned, head thrown back as he shivered at the feeling of Sirius' teeth, the tinge of pain only making everything that much more arousing. But it was the sensation of Sirius' fingers around him, curling over hot, aching flesh and urging him higher still that finally proved his undoing.
With a sharp cry Gaius arched back, body bowed as his pleasure crested, his breath torn from him as his nails bit into Sirius' back. Wave after wave flowed over him, and he gasped out Sirius' name each time until he finally shuddered and collapsed back against the foliage, panting, skin drenched with sweat and satiation. "Love... oh, love," he murmured, staring up at Sirius with a slumberous gaze. "Let me see you shatter for me."
