Queen of Night has really gotten me in to writing this story.
Disclaimer: Oh what ho, is that ownership of the idea I see? What a shock! Yes it is! Is there anything else I posses ownership of? Not even a little bit!
Tony is pretty unflappable. He's walked in on them screwing too many times to be healthy(they actually think he does it on purpose), and the time they invited him to join in he just smiled and told them Pepper would castrate him if he tries.
So there is conniving. Planning. Sneaking.
And they've come up with something.
Darcy is a pretty nifty programmer. So they appropriate Dummy(read- steal) and attach a dildo.
Now, you would think that the plan would be for Tony to catch Darcy mid sexytime with their new toy, but you would be wrong. That isn't enough. They are all in.
The next day finds Steve balls deep in Darcy and with a dildo embedded in his ass, in Tony's lab.
Just for good measure, Darcy is wearing a ball gag and her hands and tied to Tony's desk.
They are right in the middle of going at it for the fourth time(that serum did wonders for Steve's stamina) and Tony walks in. Humming, and focused on some new gadget he is tweaking, he wanders over to the desk and starts typing on his computer.
He really should pay more attention. He barely misses Steve's come from round two.
"Mmf." Says Darcy.
Tony looks up.
He faints dead away.
Steve and Darcy can barely stop laughing as they come.
Steve removes the dildo from his ass, unties Darcy, and naked as they day they were born, they skip away, giggling.
The skipping causes some interesting bouncing which leads to wall sex, which leads to three unconscious scientists, and four or five blushing junior agents.
All in all, a good day.
They see Tony at dinner, and he blushes tomato red and scuttles away, muttering something about going down to the lab. They bite their lips, and wait for the inevitable visit to medical.
They left the dildo in Tony's lab.
