This was how his morning went:
Tony woke up, nearly naked, and alone on the couch in the workshop. That wasn't unusual, not anymore. The naked was, but given that he'd spent the early morning hours testing his new toy, not so unexpected.
Tony Stark was no fool. Over the past weeks, he'd thoroughly tested it on various inanimate models of himself and worked out the kinks, so to speak. There was no way he would let anything that hadn't been rigorously tested near his cock. As soon as he deemed it safe (which was maybe a bit too soon, but nothing bad had come of it, so it didn't count) he stripped, fastened everything in place, and got down to really testing it.
All in all, it had been an excellent use of his time. Much better than responding to those emails Pepper had left for him on the desk. In fact, it was a miracle she hadn't already come down to wake him up and chew him out for not listening to her.
The toy was still on him — he'd fallen asleep from pure, blissed out exhaustion before pressing the release button on the remote that would open all the locks — and he patted the floor by the side of the couch. The remote must have fallen out of his hand while he slept and landed somewhere down there.
When he couldn't find it in the first few pats, he rolled over and off the couch, landing on his hands and knees and groping while he tried to blink the sleep out of his eyes. It was a square, hand-sized box. It wasn't like it could have bounced far.
But his hands groped around to no avail, and he eventually sat back on his heels, scratching his chest absently and frowning at how sticky his chest hair felt. He really needed that shower, and it was as good a time as any to test its waterproofness. He'd find the remote when he got out.
