Zany's question surprised Andrew, as he never expected her to ask that. His surprise was so much that he stopped moving and Aki, who was concentrating on enduring Andrew's cock in her ass, didn't even hear what Zany said.
Although she didn't hear, when she felt that Andrew had stopped, she turned her head and asked bewildered, "Why did you stop?". Unfortunately, no one answered her, as Andrew still hadn't gotten over his state of shock and Zany was embarrassed that Andrew didn't say anything to her proposal.
Because of this, Aki was starting to get annoyed. She felt Andrew's thick cock inside her, as he hadn't taken it out, but his not moving didn't give her any pleasure. Annoyed, she screamed, "How long will you make me wait?".
