Tell your own funny sex story

Ok I will star with one of my own.
This happened when I was younger (a long time ago LOL) I was on vacation with my boyfriends family, they were staying at a nice apartment in a top floor near the beach. One very hot day me and my boyfriend were very very horny, it was about 3 oclock in the afternoon so it was very diffult to do anything. I mean we dont have a room for ourselves we share a room with his brother and his sister and the other room was for his parents.. anyway I was teasing him very hard, touching his leg under the table and licking my lips sensually all the time. At one moment he couldnt take it anymore and said to me. how about if we go to the shop and get some beer? I agreed,
he took the keys and open the apartment door I followed him, at the moment he closed the door he kiss me passionately and push me very close to him, I was at that point so horny, he keep kissing me and begin to touch my breast (I was only wearing a short and my bikini set because it was so hot that day) my head was spinning and I even dont mind being in the front door of the apartment, I even felt his bulge growing in his pants.
He took me by the hand and led me upstairs where the access door to the rooftop was. Of course it was closed but the corridor ledding to the door was out of other peoples view. I was so horny I could resist anymore I grab his full hard cock at this point and started to suck like crazy...but he wouldnt let me do my job too long. We didnt have anyprotection so I tought that was the only thing that would happen but he push me up into my feet turn me around and started to rub his cock against my asscheecks, push my to the glass windows in the access door to the roof and begin to rub my tits. He put a side my short and penetrated my pussy with his fingers it was driving me crazy, suddendly his full cock was inside me and he was pumping like crazy. My face was presed against the cold windows wile she fuck me from behind, he continued fucking me and started playing with my ass with a finger
he suddenly stop and whispered to my ear. I will fuck your ass. I was so horny at this point I dont even care... was so much about to cum that I said to him that he have to fuck me hard at my ass. He pull dowm my short and bikini and guide his huge cock into my ass hard... OMg it was amazing I tought I will faint of pleasure...
suddenly we hear a noice the door below us, the door of his parents apartment opened and his folks, brother and sister come out... they were going somewhere.
We were there freezed... listening, he was still inside me and there we are half nude and with no possible place to hide. Trying not to make a noice we keep that way for...I dont know how far, seconds, minutes, hours?. His family were waiting for the elevator and we were there just one floor upstairs.
Then we heard steps going up the stairs and his little brother asking....what is up there? My heart stopped right there, if he go up a few steps more he could see us, I could not explain what I felt, I keep hearing the steps coming closer and closer I was about to cry about to get a nervious break down right there, my body trembling, and sweeting trying not to move a muscle to do any noice...
Finally the elevator arrived, the doors opened with a saving noice and the father said to the little brother to came down with them.
We dressed up in a hurry and and went down to his apartment and then in safety laugh a lot about what happened... but I still remember that moment when my heart almost explode with excitment.
That was one funny/terrible/sexy story that I want to share with you...how about you?
