As you let go of Elizabeth, the arousal felt stronger. As Elizabeth began to turn away, you impulsively grabbed her and pulled her into a kiss, pressing your body tightly against hers again. Elizabeth seemed very surprised at first, but after a moment returned the kiss. After what seemed like an eternity, your lips finally parted.
"I'm sorry" you said. "I just felt so..."
"I know" said Elizabeth. "I feel it too."
"I thought you said you loved me as a sister?"
"As OUR kind loves between sisters. He are a sisterhood of the sea, but not biological sisters. When we are not feeding on men, we are often intimate with each other."
This time Elizabeth initiated the kiss, slowly and delicately. You returned the kiss and reached around to her back to untie her tiny bikini top. As that fell to the sand between you, Elizabeth helped you pull the baggy shirt you wore off over your head. It seems the two of you had gotten dressed just so you could get undressed.
