He is allowed to cum when i say so

Description: I lock his cock in the morning and go out for shopping. at night i come back home wear my strap-on and start teasing him. unlock his chastity cage and then i start fuck his ass with my new dildo "my slave is always ready to get fucked by me". when i told him that he is allowed to cum he start jerking of his dick for me with my big strap-on inside his amazing ass. the cumshot was very big and squirty, his eyes and his body looks so relief.
