I was in chastity for three months, and then I ruined it. Master was playing a game where he brought me to the edge and then stopped, and then started again. We'd do this for hours. I accidentally came when I wasn't allowed to, so I have to go into chastity for another six months without any pleasure at all!" She frowns, "I would've loved to play with you..."
You could see that Xavier was enjoying this. He liked making Sophia say these things and feel embarrassed, and you were glad that you weren't part of his BDSM play.
