Hurry
Their breaths were misty in the night air. It was cool, and yet their skin was ablaze with heat. Sweat glistened in the moonlight as their moans were throaty and hurried in their ears. Lucius was thrusting against Bellatrix, their bodies beating urgently against the side of Riddle manor. She came first, screaming a muffled scream into Lucius' shoulder as he threw his head back and let out one final grunt.
After they caught their breaths and refastened all of their clothing, Lucius cleared his throat. "We had better hurry, Bella. With luck the meeting won't have started without us."
