Door 10 - Where's your G spot, loser?

How wonderful it is to kneel and drool in front of your domina. You can be glad that your mistress takes so much pleasure in losers like you. I like to humiliate you while wanking and make you cum exactly according to my instructions. And today, you freak, it's your tight little butthole. You didn't know you had a G-spot too? Well, my deal is pretty simple today: either you find it with me or you don't cum!
