You've been such a good slave, an overachiever, actually... and you know what that means: you've earned your weekly milking. You must be so horny what with me rubbing up against you, teasing you all week, telling you how wet I am, bending over in front of you. This whole time I have enjoyed getting you hard, keeping you on the edge of orgasm and then locking you up in chastity. You may just graduate to fuck toy if you first prove yourself... show me you can last without prematurely ejaculating. If you fail: it's a month of chastity for you.
