Mind over Matter

Honestly, Robin had just wanted to use it for a prank to get back at Lissa. He hadn't expected it to actually work, or to...this degree. After all, what kind of tome - even one that had allegedly been around since before Marth's time, if Miriel's aging process was correct - could possibly dictate enough power to control another person's mind entirely?

Of course, it was almost completely useless in combat, what with the casting time and limited range (and the fact that as soon as he left the range, the subject would not only fall out of his control but also have no memory of the time they were under his influence), but the sheer fact that it worked at all had astounded him. And the thorough testing had led him here, to Chrom's little sister sitting under his desk and obediently licking his cock. 

"Is it good?" Lissa asked, stopping to rub it with one hand. Robin nodded mutely, running a hand through her hair, and hte princess resumed sucking. 

This is actually happening. 

Good gods, she was married. Still, it wasn't like he'd get her pregnant, and she'd never know either...besides, hadn't he earned this? Three strait years of working for the royal family, making sure that they all lived perfectly intact?

He'd killed himself for them, even if he had gotten better. He'd earned something like this, surely.  But why stop here? With this, he could get what he deserved from...everyone. That's what he'd do. One night with each of them, and then he'd finally call it quits and lock the book away. It was just a reward. He deserved a reward...and respect. Respect that Lissa had, to be completely honest, very rarely given him. 

Twisting his hands around her twintails, Lissa looked up in alarm before Robin let out an animalistic growl and started thrusting, his cock ramming into her throat over and over again. The princess tried to pull back, but a harsh command from Robin - "don't" - stopped her, and she sat there and took the suddenly brutal face-fuck, tears gathering in the corners of her eyes. His growls turned into moans of pleasure, and after a few moments he pulled out of her throat and pointed his cock at her face. Lissa coughed, rubbing her throat and yelping in surprise as Robin came with sudden force, splattering her face and hair with thick cum. 

Panting, the tactician fell back into his chair and ordered Lissa to clean up, which she meekly did. Yes, this plan would work quite nicely. The only question now, however, was who to approach next?

(A/N: Lissa's full chapter will come at another point, this is just a prologue)
