Just let her decide, and keep the option open for another night?

As Martin had promised, she was ten minutes away on the expressway, and he pulled up at her door at 12:45.  He reached to kiss her once more, and this time her mouth opened.  The kiss became a long one.

   "I suppose that I don't know you that well," Lisa said, " but I would like to invite you in for a little while.  Can I trust you?"

   "I would not make you do anything that you don't want to do," he said.  "But I don't guarantee not to find out what that is."

   "Like Carmen said, you are +fairly+ safe.  I don't think I want to do quite what she and Joseph are doing tonight, but I do want to talk to you some more."

   Martin was surprised at her frankness, but perhaps she was more affected by the **** in the punch at the dance than he thought.  He had tasted none of it in her mouth, however.

   Nor did he taste it a few minutes later when they kissed on the couch.  This time she became visibly excited, even flushed.

   She trotted off to the bathroom after a while and when she returned he took her into his arms as they stood.

   Should he just kiss her goodnight, and leave anything more for another time?
