My submisive life with my dominant wife

in my life my wife tells me what to do and when.
if i dont follow her orders i get thrashed or i am left in my chastity cage till she lets me out.
i have been enclosed for two years at times .
for a reward i am milked or i am allowed to look at her pussy and wank for twelve mins and if i dont cum in the time allowed i am re locked again .
at times my wife brings her friends around to watch as i am milked or they join in and help or just torment me while i am tied up.
my wife often ties me up and brings home a lover and i have to listern from next door to her moans and screams .
now and then i am tied at the foot of the bed to watch my wife struggle to accomodate a big cock or two .
she has three c***dren by her lovers .
i was told that she wanted strong offspring not my weedy efforts.
the two eldest ones from about the age of early teens totaly disrespected me and often slapped and beat me while their mother just laughed saying that her strong daughters would in turn dominate their own fufure husbands.
