The Magic Stone
Story by Kotelette on SoFurry
Heather discovered a magic stone that she shows to Hiccup and Astrid. Touching the stone results in her breasts growing, her body fat to reduce infinitely, and eventually a cock to grow just above her pussy. Hiccup and Astrid are completely amazed by this and help pleasure both of Heather’s sex organs.
“Heather is already coming back?!" Hiccup asked confused.
“Yes. She found a weird glowing stone on an abended island and she wants us to take a look at it," Astrid explained to him.
About two hours later, Heather's boat arrived, and she hastily got on land, running towards Hiccup and Astrid.
“Guys, guys, guys! You need to help me; I think this thing is some kind of magical item!" Heather shouted completely out of breath.
Hiccup and Astrid tried calming her down, bringing her to Hiccup's hut so she could tell them a bit more details about this stone she found.
“So, what is this magic thing you were talking about?" Astrid calmly asked Heather.
“At first, it was this weird feeling I was getting every time I touched it, but then, it began changing my body, but only temporarily!" She reported.
“Oh, ehm, wow, this sounds really weird. What kind of changes?" Hiccup questioned.
“Well, ehm…it appears to reduce my body fat and enlarge my breasts." She admitted blushing deeply.
“That sounds…ho-interesting," Hiccup said, giving Astrid a mischievous idea.
“You know, we've never seen something like that, and it doesn't appear to do anything horrible to you, so I'd suggest that we try studying its effects on you when you touch it, only if you don't mind of course," Astrid proposed.
“I think you just want to see my breasts grow, Astrid. But, I do have to admit liking the idea as well. I mean, maybe this could be the best fun we've ever had," Heather agreed.
“Perfect! Let's get you undressed!" Astrid shrieked, walking over to Heather to help take her clothes off.
Seeing Heather get naked gave Hiccup the last bit of indications that they were going to have sex again, so he began unclothing as well. When Astrid was done helping Heather, she did the same, stripping down to complete nakedness. Heather then took the stone out of her bag, showing the beautifully glowing colors to her friends.
“Wow!" They said in unison.
“I think I feel it start again," Heather informed them.
“Omg! Hiccup, look at her skin! It's getting thinner and tighter!" Astrid noticed.
And indeed, Heather's body fat seemingly got absorbed by the second, her ribs and muscles getting more and more visible. Astrid now placed a hand on Heather's stomach, feeling how her skin basically felt nonexistent anymore, Astrid thinking she was touching her bare muscles.
“Heather, this is really hot! I can clearly feel even the tiniest details of your muscles!" Astrid admired.
“It's true! You can see every single vein on her," Hiccup added, similarly admiring Heather.
Astrid got so lost in her trance of admiring her so defined muscles that she didn't even notice Heather's breasts starting to grow at first.
“Astrid, look! Her breasts are getting bigger!" Hiccup pointed out to Astrid.
Astrid quickly looked up at them, watching intently as they continuously got bigger and bigger.
“Holy crap, they're getting big!" She noted, suddenly grabbing them, unable to resist her internal urges.
Hiccup's dick was quickly rising to full mast, seeing how Heather's breasts were now almost double their already enormous size. Especially watching Astrid intensively kneeling her big orbs, her wetness literally dripping to the floor.
But what astonished him even more was what he was now noticing about Heather's groin; something seemed to start growing there.
“Ehm…Heather…I think somethings weird is happening to your groin," Hiccup pointed out.
“Omg, Heather! You're growing a penis!" Astrid shouted, realizing what was happening to Heather.
“No way! It does this too?!" Heather squeaked.
The trio couldn't believe what was happening; Heather currently growing a decently sized shaft just above her clit. When it seemingly reached its maximum length, there even began forming two testicles just under it, equipping her with balls too!
Astrid was unable to close her mouth by the shear fascination she had, just staring at it wordlessly for what felt like an eternity.
“I…I have to know if it's real," Astrid said before quickly getting down to take Heather's cock into her mouth, instantly moaning upon contact; it felt incredible. She could smell two different smells at the same time: the one from Heather's pussy as well as the one from her newly formed cock, driving Astrid insane with arousal. Heather was moaning now as well, the completely new feeling of having a cock that was on top of things also currently sucked on by Astrid, driving her mind wild with new senses.
Hiccup couldn't believe his eyes, but his cock definitely had definitive feelings about this, getting him to go over to Heather and suck on her still unattended pussy to present her with two care takings at the same time. Astrid was really surprised, seeing how Hiccup was currently getting to work on Heather as well just a few centimeters away from her. Hiccup also thought this was crazy, seeing how just above the place where he was suckling on Heather's pussy was the base of her cock that Astrid was currently sucking on.
Heather's mind was on fire, feeling twice the amount of pleasure she would normally feel which made sense to her given that she had two genitalia now.
Astrid was currently getting a steady stream of precum, absolutely amazing her that she was currently gulping down actual cum produced by Heather's cock, even liking the taste immensely, reminding her a bit of her juice taste but a bit creamier and more intense, gladly swallowing everything she'd got.
Heather was struggling more and more to withstand such intense pleasure, feeling how she was awfully close to orgasming now. Hiccup noticed this as well by the increased rippling of her folds and increased his tongue ministrations to his best abilities. Astrid had a similar hunch by the way Heather's cock was twitching in her mouth, increasing her sucking just like Hiccup did.
And then she came; her cock released huge spurts of semen right into Astrid's awaiting mouth while Hiccup was receiving a similarly big load of warm feminine juices right into his mouth.
Heather was in pure bliss, experiencing two orgasms at the same time coupled with experiencing her first cock orgasm ever; it truly was a delight that even kept going for quite some time, the stone apparently having boosted her in this way as well.
When she was finally empty in every way, Hiccup and Astrid got off her to congratulate her on this amazing moment she just had, telling her everything special they've noticed.
Astrid went to feel her up again, still enjoying her so exposed veins and muscles greatly. Hiccup noticed how painfully wet Astrid was and offered his help to her which she gladly accepted. Him quickly getting to work on her folds as well, adding her drink to Heather's one in his stomach. Her juice flow was especially high due to Astrid's constant admiration of Heather's body. Especially when Astrid grabbed hold of her shaft and explored it in great detail, Hiccup clearly noticed how she was literally pumping her drink into him, quickly getting to orgasm as well which only 'overjuiced' him even more.
When Heather and Astrid were fully satisfied, they noticed Hiccup's painfully erect shaft and didn't want to leave him unattended, so they told him to lie down on the bed in order for Heather to take care of this problem.
Heather positioned his hard shaft right between her unbelievably enormous breasts, letting the tip slightly enter her mouth. She then began squeezing her breasts together and began pumping his shaft up and down, milking his seed into her mouth. This beautiful feeling on his shaft, added with the amazing hermaphrodite doing this to him, caused him to reach his orgasm pretty quickly, spraying his decently sized load into Heather's mouth who gladly gulped it down, deciding she still loved his taste.
