"I sure do," Lois said teasingly and pulled him into the janitorial closet.

Lois put her arms around him and pulled him in for a kiss. Not protesting at all, Clark returned the kiss and deepened it when Lois parted her lips slightly to invite him in. He
pulled back and looked at her through the dimness.

"If I knew this is what would have happened in the closet, I wouldn't have corrected your error last month," he said, laughing.

"Who would have thought," Lois said to him, "that just over a month after we met, we would be doing this," she said as she continued kissing him, pushing him up against the wall
again.
