While it was probably not what she had intended, though Loki could not be sure, as soon as Sigyn said it his mind was already coming up with all the different things a woman could do naked in a bed to entertain herself. There was no stopping the thoughts the second they started flooding in, no matter how unlikely some of them were in regards to the woman he was currently holding against him, and he was trying to keep any physical reaction to thoughts she didn't need to know about him having from coming up.
Along those same lines, was that her saying that she was making repeats of the incident that had caused her to run off with a concussion? Because if that was the case Loki was really going to have to have to find a delicate way to explain that as much as he would like to... would really like to... he was trying to not turn this into just another lover.
“It's fine,” he said with a chuckle. “I don't mind. Go in there whenever you want, just... be careful of who is watching until Frigg is dealt with. Whether I'm there or...”
Suddenly, his words were lost. Breathing stopped, his heart may have stopped... Loki wasn't certain. But Sigyn had placed her lips on his throat and all the thoughts he had been fighting to push back flooded forward. He had a moment to breathe when her head laid down and he had to think quickly about what to do. He had restraint, he was not an animal... but she was clearly willing and tempting him. Even Loki would break eventually.
Then she did it again.
For Loki, he was feeling warm. It was time to come up with a reason for her to put her overdress back on.
“So,” he asked, upper body leaning back a bit to give just a bit of distance, “when do you have to be back? Is Frigg going to send a search party? Or do we have time to finish your paints and then go for a wander?”
