Severus' lips curled in the smallest of smiles. "Then, yes, but not anymore." Discretion was still necessary but hiding outright was not. Being careful went without saying.
"No more discussion," he said. He pulled away and settled on his knees between Draco's legs. He arched an eyebrow, appreciation and amusement warring in his eyes as he looked down at his lover. Draco looked like an invitation to sin and who was he do deny that?
He reached out and ran a hand down Draco's chest and stomach, curling it around his cock and stroking once before moving further down. He brushed a finger over Draco's entrance and cast the spell to prepare him wordlessly and wandlessly. He then leaned forward and kissed Draco, enjoying dragging this out as long as possiible... or as long as Draco would let him.
