Paternal

"Do I have to, Dad?"

"Yes, Hiccup. Like I said, the couple in need specifically requested you to babysit their daughter while they go off to visit their relatives on another island."

"B-But I have dragon training with the others to take care of! And don't get me started on Astrid's or Ruffnut's reaction to this... Who knows what they'll think when they see me with a baby in my arms... Let alone do to me..."

"I know, and for that I am sorry, son. Then again, I'm sure you can think of something."

"... And that's why little Sigrid's here with us today, gang." Hiccup finished explaining to the gathered dragon riders, while careful not to let locks of his hair get grabbed by the energetic bundle in his arms. "So you can put your weapons down now, Astrid and Ruffnut."

"What weapons, Hiccup?" They both asked him sweetly, their faces the picture of innocence as they casually hid them behind their backs.

"You two know what I mean." The brunet sighed, and adjusted his hold on the baby. "Anyways... irregardless of my babysitting little Sigrid, we're still going to have dragon training today."

"Ooh, ooh!" Fishlegs raised a hand, causing everyone to look at him. "Can we take turns taking care of her, Hiccup?"

"Yeah! Why not let us hold her too, Hiccup?" Tuffnut excitedly asked as well, surprisingly enough.

"Um." Hiccup frowned as he carefully looked back and forth at the two eager boys, and then glanced at Sigrid. "There's one reason why I won't let you guys hold her."

"Which is?" A confused Snotlout gestured him to continue.

"She won't stop crying if someone else other than me or her parents carries her."

"Oh."

Today's dragon training turned out perfectly well despite Hiccup being busy with babysitting Sigrid, and after they sorted everything out in the academy, the gang went home as a group to Hiccup's house where they spent their time just watching him take care of her as if she was his own daughter. Whether if he was aware he was doing so, they didn't know, nor did they really care. They were quiet as he paid close attention to Sigrid and attended to her every need, with the caring brunet even going as far as to hum her a sweet and gentle lullaby that sent her and the other boys - including Toothless - to a peaceful slumber when she started to cry. Minutes later his humble room was filled with a lot of snoring - some very obnoxious, some not so much.

It took Hiccup time after he finished humming, but eventually he realized he was alone with two pretty girls - in his room, no less - who were interested in him, and despite the fact that there were others asleep in his room, he didn't feel safe at all being left awake with Astrid and Ruffnut - for the girls were giving him dreamy looks, and their eyes were also filled with desire. The sight of them looking at him like that were enough to leave Hiccup feeling extremely uneasy, and the fact that he seemed to be good husband material to them wasn't really helping his case.

"The sooner Sigrid's parents are back, the better." He thought as he nervously gulped. "I wish Dad was here."
