This happened last year when I[32M] and one of my cousins[33M] went to meet a friend[32F married] of his. She was in Delhi for a couple of days and was staying in a hotel. The plan was to meet her in the hotel lobby (it was in Connaught Place), but when we reached there she asked us to come to her room instead of waiting for her to get ready and meet. Now, I knew that he was going to fuck her which he already told me. And I was supposed to wait in the lobby. But when I went to the room and we started talking she took a liking to me and so we decided that I can stay in the room when they do it. I tried not to look when they started it, but when she was being fucked in doggy she asked me to come closer and placed her hand on my crotch area it was already hard :D, then one thing led to another and she started sucking it, it was an amazing feeling. It was good to see her enjoying the fucking as well as sucking at the same time. So that is how I entered an unexpected threesome. We took turns fucking her and it was really good. We left after only one session as we had to leave quickly (that is why I decided to wait, I thought it would be over quickly).
