You can ask any 3 Wheel driver (Auto Local name) to take you to City Center Post Office this is a discrete way to get to Pune's Red Light Area. The Area is called "Budhwarpet". Once there you will know right away day time or night that your in the right area as soon as you stop, because of the women standing around. This is a fairly large area, but my advise stick to the side on which the post office is located, the otherside has Tranvestites who damn near look like real women.
You will find lots of decent women in this area. Most are from various parts of the country and Nepal. The Nepalese girls tend to be more docile. Some provide good service. The cost is cheap. You can also arrange to take them back to your hotel. The problem is trying to find a hotel to sneak them into. If you decide to do the deed at her place, be prepared for tight quaters. Some Nepalese girls can give you a great time, even in these tight surroundings. The Girls are all prepared with Condoms, and mostly wont have sex without one. But some offer BBBJ's also, depends on the girl. Most of all be flexible and Enjoy.
