Agastopia: Admiration of someone's body.
"These are all your fault, you know," Loki says as he looks at himself critically in the tall looking glass standing beside their armoire and rubs at the silvered stretch marks that still litter the creamy skin of his inner thighs. Thor, in the middle of unbuckling his armour, cannot help but stare at Loki's naked body.
Loki catches him staring over his shoulder, and grins impishly as he spreads his thighs a little further, inviting Thor to look and accidentally drop his breastplate onto the floor with a loud clang.
"Well, technically," Thor says, his mouth suddenly dry, "they are Modi's fault, not mine. I was not the one inside you and stretching out your skin."
Loki arches an eyebrow at him. "No? I seem to recall it quite differently during my cycle. Alas, how am I to know the truth? Events during that time are very like to be all skewed with heat and lust."
Thor swallows roughly, his eyes sketching across the planes and slender curves of Loki's long body, tracing each and every stretch mark with a burning gaze that has heat coiling and tingling at the base of Loki's spine.
"Perhaps," Thor says roughly, his voice husky, his eyes dilated, "I might be able to remind you of what exactly transpired during that time. To help your memory, of course."
"It would be a sad thing to forget," Loki muses, and in the dim reflection of the mirror, Thor can see Loki's cock begin to stiffen against his thigh, can see a light flush creeping across Loki's chest, and longs for nothing more than to lay his mouth on soft, sweet skin and suck and bite and lick.
"Most definitely," he agrees. "It would truly be a shame if you were not to remember it."
Loki grins, the curve of his mouth gleaming in the mirror as Thor steps hurriedly out of his trousers and reaches out for him.
