After recent examples of good behavior, my mistress has decided that I deserve a reward. I haven't been allowed to orgasm in weeks, and it is due time she's allowed me to have my leg humping reward. My mistress leans against the wall, and directs me to walk to her. She motions me to straddle her thigh as she extends it out a bit. She allows me to start humping her thigh like the good slave in heat I am and I thank her. After a bit, she tells me that I better hurry up she doesn’t have all day. As I am near orgasm, she firmly grasps my hair and I cum all over her thigh, thrusting in and out. I am behaved so well up until this point that she pities me and allows me to rinse and repeat for a strong second orgasm. She won’t be giving me another chance for this in a long time so I cherish this reward.
