Alecto grinned evilly against Spencer's neck. She had no idea that she would get that much of a response out of her from what she was doing. Now she knew that Spencer's weak spot was her neck. That would be good information for later. For now, she just enjoyed the reactions as her lips and teeth wandered over Spencer's neck.
"Does that mean you are ready to try?" She wasn't even able to keep up the pretense anymore. "Tell me you want me inside you. Tell me that you can't wait for me to shag you rotten until you come for me."

Taking her wand, Alecto silently used a Reduction Charm to make the cock a bit smaller. Because she hadn't seen her do it, Alecto didn't altering things a little in light of the newly acquired information that Spencer had never played with toys before.
Plus, she knew that Spencer would be stretched around it and get that perfect mix of pain and pleasure with her cock a slightly smaller size.
Ready to begin, she prepared to cast a spell that would lash Spencer spread eagle on the bed the moment she told Alecto what she wanted to hear.
