Zephyr ask "Nuffink? Do you love me like a sister or more?"

Nuffink ask "like mates?"

Zephyr nods her head "yes."

Nuffink quips "well we still have years to find mates before continue our bloodline."

Zephyr sighs "look at ourselves! We're hybrids. No one may want to date us. We only have each other."

Nuffink sighs "your probably right."

Zephyr comments "we could start with a kiss or wait."

Nuffink comments "parents would be mad at us."

The kids left them to go eat dinner.

Zephyr change into her Night Fury form and flew to the cove to catch fish to eat.

Nuffink change into his Night Fury form and chase after her.

Five minutes later, Zephyr landed by the lake and says "I win."

Nuffink crash into his sister laying on top of her back.

Zephyr groan "Nuffink? That hurt a little."

Nuffink raise up to move off when Zephyr felt his member rub her tail.

She move it to the side and back into his member touch herself.

Nuffink gape in shock "Zephyr?"

Zephyr licked her brother's face "No one would know what happen out here."

Nuffink ask his sister "what if I get you pregnant by mating with you?"

Zephyr answers "I'm not old enough to get pregnant by you."

Nuffink worries for his sister "Zephyr? Mating would cause you pain."

Zephyr nuzzle her brother neck.

Nuffink nuzzle back.

Zephy moans "Nuffink, put your member in me."

Nuffink groans "I can't."

Zephyr moves her body forward and back to get her brother to enter center to whimper at the intrusion.

Nuffink groans at what his sister did to him.

Zephyr moans "move your hips."

Nuffink sighs and begins moving his hips back forth.

Zephyr purrs at the feeling.

Nuffink sighs "how long did mom and dad go for?"

Zephyr answers "I don't know."

Nuffink pulls out and says "let's promise to never mention this to anyone."

Zephyr chuckled and licked her brother "I love you, brother."

They eat fish and fly back to the Haddock home to sleep.

In the morning, Hiccup and Astrid return with an army of dragons to protect Berk.

They changed into human form.

Zephyr hugged her father while Nuffink hugged his mother.

Astrid curious ask "what did you two do while we were gone?"

Nuffink answers "dad's parents told us about Zephyr as a baby."

Hiccup sense something different about his kids.

Zephyr grins "they told us that I like to fly around before bed and mommy got too mad."

Villagers rebond with their dragons.

Zephyr and Nuffink were surprised that Toothless had babies with Luna.

When dinner time came, Astrid put her daughter to bed and says "you and your brother seem to bond while we were gone?"

Zephyr smiles "we're a family."

Astrid ask "what were you thinking?

Zephyr answers "I was wondering if we would find mates to continue our bloodline in the future when we get older."

Astrid ask "your too young to think about mates right now."

Zephyr smiles "I worried about my future of finding love because of my powers."

Astrid sighs "it's okay, daughter."

Zephyr smiles at her.
