She seemed to blush and be somewhat intrigued by my suggestion. I noticed that her cute little nipples seemed to become more prominent through the tig...t tank top she was wearing….apparently with no bra beneath it. I think her nipples twitched a bit, as did my cock. Lisa winked at me, and I returned her wink. Then I walked over to her and said, “Lisa, if we are ever under a Tornado Warning or Severe Thunderstorm Warning you can come over and seek safety in my storm shelter with me.” Our flirty.
