Risky shower sex

So there we were on a party night for an organisation we worked for. The night progress lots of drinks all around when my gf grabbed me by the hand and whispered into my ear " come with me" pulling me towards the door into the next room. Being a little quieter here she said huskily "follow me" and we went into the basement where the changing rooms were. Once inside she looked at me with total lust and came close and we kissed passionately our tongues entwining searching out all the nooks and crannies, my hands working around her plump round arse making her grind into my crotch slowly pumping blood into the shaft. After a time we seperated and quickly undressed know someone could come in at any time adding to the passion we both felt. Once naked we again began French kissing our hands running over each others bodies grinding into each other both breathing heavily. I was now standing to attention so she dropped to her knees and took my shaft into her mouth sucking me not slow but hard and fast choking every now and then as my cock hit the back of her throat. The shower was running water falling over us both as she suck, i had to stop her and we swapped places me on my knees licking her pussy water cascading over me as she moaned and grabbed my head pulling me into her deeper into her cunt. I pulled her lips apart and went to town on her pink pussy lapping up her juices, she had to lean against the wall as she twitched with joy. She pulled me up and bent forward so i could enter her from the back her cunt dripping as i slid in. I began to thrust in and out her tits bouncing as i did her moans becoming more lustful backing on to me matching my thrusts, I began to speed up my balls slapping against her arse holding onto her hips as i moved in and out of her. She had to hold the wall to keep from falling over water still running over us. I was really going for it now speeding up and up until with a groan I shot my seed into her and she kept backing on to me until she on me her pussy muscles clenching tight on my hard spent cock. After a short time we seperated and kissed each other passionately panting our hand slowly caressing each other recovering from our risky sex. I don't think anybody came down and no one said anything as two red faced people rejoined the party.
