Her body trembled lightly when he pressed his tongue against her harder, her toes curling a little bit. When she had found out that she was going to have to marry a demon, she thought it would be passionless feelingless sex with him as often as he made her. She hadn't thought there would be foreplay, actual attraction, and desire. There was tension between them, but that just added to what they already had.
His tail exploring her body made her unable to focus. One moment it was rubbing her back, the next caressing her lips, the next it was still and she could focus on his tongue. It figuratively kept her on her toes, kept her looking for what was next. When his tail whipped her ass she squealed, her entire body jumping. Her eyes grew wide, the sting of pain hadn't been at all unpleasurable. "Yesss," she moaned in response to his question as he pushed his tongue inside of her.
