in my life a lot time i did such sex , one memorable was in a small town in central india with someone , we were travelling by a cab that got stand still in middle of the road suddenly around 10pm at night all around dark , driver told that there must be some difficult problem that he can't fixed by own so he stayed at car till morning and told us to arranged a stay for night , we started walking and after 20-25 minutes later found a Dhaba (Sarai) , no rooms there but they agreed to give us the rooftop single storeroom for the night and after having night meal , we went there , a very dark small almost dusty room with a wooden bed , a door was there to enter but only door frame no door leaf with a nasty curtain I saw in deem light of lantern , I remove that completely so some air can pass and put the lantern off and we removed our cloths and get completely naked and started to achieve the thrill of high ending sex to overcome the travel lag and tiredness in that dark , after a while we feel that there was some one on rooftop front of the door but we didn't stop as per situation , later when we finished we found that a boy of 13-14 sleeping on the rooftop under open sky ,
