This is a genuine question that you asked which some of the members shy to ask. I want to bring one of my recent experiences of staying in hotel for a business meeting for two weeks. When one of relation ( a girl) came to meet me at the hotel reception and we have plan for a lunch in the ground floor. Before this I had already informed the hotel reception for this in advance so that nothing will mesh up. But the incident happened was totally different and the staffs reacted in such a way that I felt embarrassed situation. Even if I don’t have anything wrong in mind they suspect me and in your case its totally opposite. Dear friend you have to take care of the situation prior to enter to the hotel else you would face problem.
The hotel staffs are purely business minded and ready to insult you in between but there are hotels who behave professionally and never interested to interfere in private matters. Its better to choose a place far away from railway station or airport so that you can have fair chance of getting a good place and hotel should be reputed. Don’t compromise in money and invest in a star/reputed hotel.
Its better to have session in her home. Its better to ask her about possible safe places for have sex. I am sure she would find place in her friend’s home or anywhere which you couldn’t think about.
If you want to take an aunty other than your own then the arena of analysis or suggestion would be different. Be open up with your question further so that members can able to suggest in a broader way. Hope you will reply accordingly.
