"Okay." Hannah smiled cutely as she unconsciously snuggled a bit more into Megan. "I believe you."
As Megan stumbled for words - Hannah noted this as the first time she had Megan stumbling, Hannah was working up the courage to push things further and actually kiss Megan.
For Hannah, there wasn't anything hypothetical about it, though she portrayed it that way. In her fantasy, it really was Megan who was her lover...
At Megan's challenge, Hannah finally worked up the nerve and brought her lips to Megan's in a gentle kiss, almost as if she was afraid the other girl would reject her.
