That is so hot! I really admire your willingness to take the risk of other guys fucking your wife in what I perceive to be a very restrictive social and cultural situation. It is taboo in the US for a wife to have sex with other men and for white women/wives to have sex with black men but I suspect the taboo in India is much more prominent.
I worked with a gentleman from Hyderabad. He found it odd that American guys talk to each other about sex. He claimed that Indian men do not discuss sex with each other. It must be difficult to bring other men into having fun with your wife.
Do you like to watch? Would you/your wife like one-night-stands or long-term relationships with other men?
