Astrid's moans weren't very quiet. They echoed off the walls of the cove as she felt both Viking and dragon thrust. Hiccup was behind her, moaning into her ear with every thrust from the dragon who was behind him.
They had all agreed they were in a shared relationship, and they now have a weekly (sometimes daily) outing to the cove to please each other, whether it's two of them while one watches, or all three of them. They always found new ways to get involved with each other. Most of the village had gotten word of this shared relationship and had begun to try spicing up their lives with their dragons as well. This was to be the last time for a week that they would be able to do this as a threesome due to Astrid having to go to the far off lands as a diplomat between Berk and the meatheads.
"I love you so much Hun" hiccup whispered into Astrid's ear as he pumped in and out of her slick hole. Toothless gave an appreciative growl to hiccup as his balls slapped against the Viking boys ass. Soon both Hiccup and Toothless began pounding hard, causing all three to moan loudly in unison as they approached their peaks. Astrid gripped the back of Hiccup's head, pushing her fingers through his hair as the pleasure got more and more intense. Hiccup bite down on her neck, marking her as his as he felt Toothless' thrusts get more and more erratic with his release getting close.
Not even 30 seconds later, all 3 moaned loudly, scaring off birds perched in nearby trees, as they all released. Toothless pulled out of Hiccup and as soon as he dismounted him, Hiccup collapsed onto Astrid, exhausted. Astrid, also being exhausted, couldn't hold them both up and collapsed onto the ground, panting. After a while of heavy breathing Hiccup finally woke up "Ahh I'm going to miss you so bad milady…" He said with a sly wink towards her as he got up off her "I know babe, I'm going to miss you too" She had also gotten up and was walking around the cove, picking up her clothes, which had been trailed from the entrance of the cove, they having stripped while they walked to their normal spot.
Toothless made a growl, as if to agree with Hiccup, after all, he would be missing out as well, and he had become very attached to Astrid. "But don't worry my boys." said Astrid. "I'll more than make it up to you both when I get back but in the meantime you two play nice… Or rough" she smirked at them both. Toothless warbled a laugh while Hiccup just chuckled. "Can't help nature, if it happens it happens" Astrid couldn't help but giggle at the pair of them "Yeah natural urges can be rather powerful" Hiccup chuckled. "Yes, but also rather fun" Toothless warbled in agreement again, making the Viking couple laugh.
They kept talking, laughing and generally have fun and enjoying each other's accompany, until they had reached the village. Astrid sighed in sadness. "Well… I guess I'll see you both in a week…" Hiccup pecked her on the cheek "Don't worry dear, we'll be thinking of you while you're gone". Toothless nodded his head in agreement, looking up at Astrid with big sad eyes. Astrid smiled and lifted Toothless' head slightly to kiss Toothless' nose. "See you later boy" She then grabbed Hiccup's face and kissed him roughly. "See you soon babe". "Goodbye for now Hun" he replied, waving at her as she boarded the ship.
Toothless and Hiccup went for a flight to burn off some adrenaline, and then went to bed after dinner. But the next day, Hiccup was already feeling lonely, not having Astrid next to him. He looked over at Toothless who looked back with wide eyes.
"Wanna go to the cove?" Toothless' instant nod put a smile on Hiccup's face. They were soon in the cove and Hiccup had stripped down. Toothless was instantly on him, licking hiccup's body all the way down to his semi erection. With a few gentle licks of Toothless' tongue, Hiccups cock was soon at full mast and standing to attention. "And now to repay the favour" Hiccup said as he crawled beneath the dragon and started to lick at the dragon's sheath, coxing the dragon's member out. The dragon purrs as his shaft was quickly moving to greet him. The boy beneath him grinned and brought a hand up to fondle his balls before licking them, tasting the powerful musk. The dragon moaned above Hiccup, which encouraged Hiccup further.
Soon Hiccup's mouth was full of Toothless. The dragon would rock himself in and out Hiccup's mouth, enjoying the boy's mouth. But Hiccup was getting inpatient and pulled Toothless out of his mouth and got on his hands and knees, presenting his rear to Toothless. Toothless didn't hesitate, he mounted Hiccup and was straight in Hiccup, making them both moan out.
Toothless began with a gentle pace, going in and out with a slow and smooth movement. Hiccup moaned softly, enjoying the slow pace. However, it wasn't long before he wanted more. More rough. More Toothless. Toothless must have sensed it before he started to rock faster and harder into Hiccup, crooning into Hiccup's ears as the boy arched his back and moaned. Toothless nipped and licked Hiccup's back as he slammed into the boy, going as deep as he could.
The Viking boy was in complete ecstasy, his loud moans encouraging the dragon. After a while they could both feel their release rushing to meet them. Hiccup panted and moaned like a dog in heat. Toothless moaned and with one final deep thrust, they both moaned and released, Hiccup having tears in his eyes from the intense pleasure. The dragon panted above the boy before dismounting and laying down. Hiccup rested next to him, leaning against his side.
"Thanks for that bud" Toothless roared a reply sounding almost like "thank you" and Hiccup smiled, rubbing his best friend's head.
Over the week, Hiccup and Toothless had fucked every day, up until Astrid returned from her trip.
The pair greeted her happily when she returned, Hiccup passionately kissing her and Toothless pushing the pair to the ground, licking them both happily. "Ugh Toothless! You know that doesn't wash out!" The couple laughed before getting up. "So how were my two favourite boys while I was gone?" Asked Astrid with a slight smirk on her face. The boys in question looked at each other with sly looks before both turning to the young warrior. "We looked after each other and were very well behaved. Can we have a reward?" "Hmm I think that can be arranged tonight" giggled Astrid who was now biting her lip and blushing bright red. Hiccup smiled widely. "We can't wait, but for now, let's get you settled back home and then go for a nice flight" Astrid gave Hiccup a loving look and wrapped an arm around his back as they started to walk up the hill to Hiccup's house. "Sounds great to me"
