So yeah. My friend is actually forcing me to write this though I don't really know why. Also, apparently I put it in the wrong section so I'm just going to point out that I have never, ever seen Avengers so everything I am writing I have absorbed through listening to friends' conversations... Again, I am aware that little sense is made and it is written really badly.
Kiss and make babies
Having successfully skipped their way back to the tower (only stopping 23 times to continue the lip lock) Tony and Loki crept their way up a couple of staircases. Loki wanted to play around in the R and D level (whatever that is) but Tony was far more interested in playing out one of his fantasies. Walking the 17th floor corridor the couple (I think we can call them that now) made their way towards the cupboard that Loki new housed a couple of brooms. Stopping briefly in front of another cupboard Tony pressed a quick kiss to Loki's lips and pulled his phone out of his pocket. Loki looked on confused while Tony double checked that the cupboard they were in front of was actually an empty one and not the one currently occupied by Clint and Tasha (conveniently everyone else had left the tower). It was. This pleased Tony and he hurriedly grabbed Loki by his long flowing hair (supposedly it is, I don't really know) and dragged him inside. This resulted in yet another tumble to the floor (well partial tumble, the cupboard was rather small). However, neither breathing thing with two legs (I can hardly call them men, Loki is a god) really cared. After all, they did only have one thing on their mind. Sex.
What followed was a rather frenzied tearing of clothes off of bodies and the throwing of said clothes over shoulders. Accidently Tony managed to successfully get his sock wedged on the rather dim lightbulb leaving the room in darkness. This made the whole situation seem more mysterious and both made the simultaneous decision to carry on regardless. There was a lot of awkward fumbling but eventually Loki managed to gain the upper hand (well duh, he is a god) and had his way with Tony. Several hours and several orgasms later the two finally rose for air. They just lay in each other's loving embrace (n'aww isn't that sweet) for a while before Loki realised that he was meant to be meeting his brother Thor for dinner in 3 minutes and 2 seconds. He hurried to grab his clothes and redressed himself as quick as possible pausing only to drop kisses all over Tony's body (yes, all over his body) before legging it out the door. Running down the corridors he bumped into Clint and Tasha who both wore ephemeral grins of relief and love for each other as well as having that unmistaken after-sex smell. Loki was unable to stop and congratulate them however as he was really late by now so he kept running, disappointed at himself for leaving his lover behind him without so much of a goodbye but all the same ecstatic that things had finally happened between them. Back in the broom cupboard Tony was feeling the same way and spent the next 20 minutes jumping up in an attempt to grab his sock from the light before running out into the corridor and releasing his joy in a yell (boy, was it a good job the place was empty).
