Anser this sentence: awww dont be terrified baby i can work somethin out for u... maybe we can come to a lil arrangement. For the context she was talking to me about onlyfan but I said I couldn't add it, being horny ask her what the arrangement is
You could respond with something like, "I'm curious about this arrangement you mentioned! What do you have in mind?" This keeps the conversation light and open, while showing interest in what she is suggesting.
