Cunnilingus

Sick of seeing Hiccup in such a morose mood, Astrid stood up.

Without saying anything, she reached under her plain white skirt, thumbed the straps of her underwear, tugged them down to knee-height and raised her skirt up. Hiccup blushed as he had gotten a good look at the tuft of blonde hair surrounding her pink flower.

"Astri--"

"Eat me," said Astrid as though it were a fact instead of a request.

Hiccup's face went from pink to red-hot and his gaze flipped from her face to her exposed area. He swallowed nervously, but rather than put up any kind of resistance, he got off of his bed onto his knees, carefully places his hands on both of her exposed thighs and got to work.

Perhaps in another life, using her gender to get results like this would have been beneath her. There was a part of her that felt conflicted even now, but it wasn't all bad. She actually loved Hiccup, and the fact that she was able to make him happy in such a way gave her a warm fuzzy feeling inside.

The fact that Hiccup was a natural at giving head certainly sweetened the deal.

They have been roommates since that horrible day and that has an effect on people. When puberty set in, both Hiccup and Astrid had caught each other staring more than once.

It was on the anniversary of when her parents were banished and she was basically sold into slavery when he told her he loved her and that he would do anything for her.

She knew that he would eventually have to marry someone else. Maybe he'll grow tired of her and find someone else, or his dad would form some kind of alliance with a neighboring tribe and he would have to marry some Chief's daughter.

In the meantime, she had Hiccup all to herself.
