After recent examples of good behaviour, your master has decided that you deserve a reward. You haven't been allowed to have an orgasm in weeks, and it's time for him to allow you to indulge in the delighted pleasures of domination. Your master starts off sitting (or alternatively standing) and instructs you to crawl towards him. He gestures for you to straddle his lower leg below the knee as he spreads it. You get into a high kneeling position and begin to press your pussy against his lower leg. The pressure is delicious and you begin to hump his leg slowly. He belittles you but allows you to continue like the good bitch in heat that you are. This instantly lights a fire in you. Your primal animalistic urges are no longer repressed as you rapidly thrust your hips in and out like a You moan in pleasure, your back gradually arching forward inside him. After a while, he tells you that you better hurry up, he doesn't have all day. You get closer and closer to orgasm (or orgasms), and as you moan in excitement, you happily cum all over his leg (see reference images A). You've behaved so well up to this point that he takes pity on you. He'll let you try to reach one final orgasm. He holds his leg out for you to position yourself and beckons you over. He won't give you another chance like this, so you appreciate this reward. In a moment, you move to position yourself against the master and eagerly grind yourself to the finish.
