Ballen vastgebonden, gemolken en op handen en voeten verpest zijn ballen in een glas

My chastity sub is blindfolded, restrained on the bondage table on all fours by his ankles and wrists and his balls are tied behind him upwards to keep them tight and out of the way while I milk his cock between his legs and ruin his orgasm four times in a row while collecting his cum in a glass. When his balls are empty and his cock is spent I write a note on his ass in marker pen and leave him restrained while I go take a shower.
