He would have answered but his lips had suddenly become very busy. Not that Mark minded in the least. He was aware that the two of them hadn't been able to have much alone time since so much was always seeming to happen. This was their time now, they were alone and enjoying each others company and it was wonderful. He loved it so much. He loved Jace so much.
His lips smashed back into Jace's and there was a small groan of pleasure that happened as he let his tongue push out against Jace's lips to dance with the others. His legs entangled the shadowhunters, almost pinning him close to his own body as legs wrapped around Jace's ankles, oops. Grinning into the kiss for a moment. "There now you can't get away." He murmured in between their kisses.
