I read chastity captions elsewhere but yours are my favorites. One thing that sets you apart is the females' voices, which neatly match their attitudes and vary from one gal to another. Also, I particularly responded to your term, "'female orgasm only' couple".
Thanks; that comment ties in well with my methods: I look at a picture and try to think what she might be saying. I like the caption to particularly match the picture if possible, although there are always a few fairly generic ones leavening the bunch.
You have absolutely the best captions!
Thanks, chastity sub, I appreciate the feedback!
