Even such a pathetic loser deserves a piece of cake on his birthday

Today is my slave's birthday, and as a gift, I'm letting him eat a birthday cake off my gorgeous feet. He began greedily licking his cake off my legs, and I immediately noticed that his cock began to harden without my permission. The stupid loser thinks he can get away with anything on his birthday, but I don't care about his birthday, the main thing is that I will enjoy while I ruthlessly beat off his erection through pain. All this time he will be forbidden to get excited, but I specifically let him admire my legs and seductively play with his manhood, thereby leaving him no chance to restrain his erection, so that for this I can hit him on his swollen balls with the strongest blows he has ever experienced. From time to time, I brought him to orgasm over and over again, only to plunge my heel sharply into his sensitive balls. At some point, he couldn't stand it, and his warm sperm flowed down my legs while I pressed my heel on his balls. (I was even a little aroused by the fact that the warm sperm of the man I had stripped of his manhood was flowing down my sweet leg). In the end, I squeezed his balls dry and drove my foot hard into his crotch, thereby causing irreparable damage.)
