Cooper, the bastard, chats with the conductor for a few minutes as he changes the speeds and rhythms of the toy. I just smile tightly, trying desperately to avoid making it clear what’s going on through an ill-timed gasp or whimper. Not that I want him to stop—I don’t want that. I just want to come, and then get on my knees and suck his cock until he calls me a slut again.
