Guys here are my 2 cents: First of all, choot marna humare liye bohot badi baat hoti, choot hume keemti khazana lagti hai lekin aurto ko ghanta farak nai padta. It's just a normal body part for them. Toh wo itna deep nai sochti choot dete waqt, jitna hum. Now add in following to it: Naye lund ka maza + belief this can get them pati ki lambi umar/success in life + safe as it will not be disclosed from the powerful person + some fear that not doing it can bring them bad luck + treating him as divine (whatever he says will come true) = Chudai which we see in the videos
