Jack thought about that for a moment, a tiny smile on his lips as his finger went to run along his bottom one to get any stray lipstick from the kiss. He took another sip of his drink then shrugged, "It never hurts to have back up, now does it?" He said with a grin. There. He had bit the bullet as well and played along. He was frankly surprised Greg was offering at all, and was almost eager to do it just because of that fact alone. He would probably feel awful about it afterwards, and plead with Jules for forgiveness, but at that moment, Jack very much wanted to make out with Greg House in the bathroom of the seedy drag club.
