Arabella enjoyed watching Ferdinand's reactions to her touch. She was tempted to use her mouth since she knew he would love it even more and his reactions would be stronger.
But she realized that Ferdinand might assume she had some kind of experience with it which was how she knew how to do it. Her first experience with it was with him in the past life though.
'I'll save it for later.'
Seeing how he licked his fingers earlier to taste her, she was sure he would try to go down on her soon. She would go down on him after he does to her. That way, she could reason since he did it for her, she would do it for him too.
After all, in her past life, that was how it began. Ferdinand always went down on her when they had sex so she wanted to do the same for him.
"Your body is so hard," Arabella caressed his arms, chest, and abs too as she teased his member.
[Her hands feel so good. Who would have thought she would touch me too? Is she curious about my body?]
