Turo: A massive story.

— I’m sorry for this mess…

Those words were his last after the laboratory of Professor Birch was destroyed, bursted and smashed, like nothing. The last words from a naked, sweaty and tender Professor Turo, almost crying for everything he had just done in front of his dear… friend with sex rights?

— Don’t apologize, it was amazing. I never felt something so pure and magical as this moment. I love the kind of passionate monster you became — and Birch kissed Turo, making him blush.

2 Hours before.

— Well… if I take a bit of this food and mix with this drink the proteins could make my muscles a bit juicier, just the close point to look a bit better as Birch loves. He is satisfied with my 10 inch cock so I just need to have more arms to feed him… Dammit, I love when he stares at my arms and starts to touch them. Like a good boy playing with his favorite toys, just following with a sweet kiss from his lips on mine.

*Flashback:

The minutes passed by while Turo was thinking about the romance with Birch, it was an open relationship. They were with Professor Mirror too. He was very helpful with the problem Birch had in the past with wild Pokémon. Mirror held Birch hands to touch a wild specimen and when it was the right moment and some laughs they were kissing. Turo was there watching the scene, and both couldn’t resist touching Turo… making his hands crazy around his muscles. The three bodies were getting closer, more and more… The breaths, those muscles… Birch was a bit fit too but no abs, big arms, fat pecs… It was maybe the bigger one of that trio. Mirror and Turo couldn’t resist to up his arms and lick his armpits, enjoying then, making him growling like a feral man. Giving them a boner, taking off pants and starting jerking off while kisses were creating something beautiful.

That night the bed burst thanks to a hard sex while Birch was fucking Turo and Mirror was getting pregnant of Turo, a train of love with positions changes, fucking every hole, cumming on each other, spreading an aroma that made them having sex for 4 rounds.

— Oh f-FUCK Turo, keep it up KEEP IT UP MY LOVE KEEP… DES-troying my fucking tiny ass OH FUCK that ITS. — Birch was growling so loud and it happened. That feeling.

Turo started to go faster, harder, even his balls were deep inside Birch the bed was crushing down, Turo was growling too but deeper, louder. Mirror was cumming a lot watching the scene, cumming over Turo shoulders and Turo started to flex his biceps pumping some veins making Mirror cumming more and more over those big balls from his arms.

Turo fell down tired and both wrapped him up, that night was magical.

2 hours before.

— I loved that moment but my mind… my muscles were growing or something strange. Maybe it was all the love, the passion and rage, the way I would fuck them harder and deeper but I couldn’t reach that point to make him cum just with a glance. But they were enjoying my body, my entire penetration… my cock and veins were pumping like crazy, all the strength. ALL, the fucking STRENGTH! — Then Turo punched the table till he tore it apart in two, just like it was made of fine paper.

His hand was sacking, the veins of his hands were getting pumped and bigger and he realized he had a big and tender boner under that sexy and blue outfit.

— Honey, I’m home! How was your day?

— Oh… no… nO! — Turo shut up his mouth with his hand because his voice was a bit deeper. It was like the other time? Were the memories? What was it exactly? Then started.

— My dear Turo, I hope you — Birch realized what was happening to Turo and closed the door just to watch what was happening to him. He noticed when they were fucking, making him flex his muscles to proof and make him growing a bit bigger.

Turo just stepped once to rip the shoes, stomping the ground, his toes free, the foot growing, the calves pumping harder and faster, destroying everything around his legs. His back was getting inflated, muscular and tense.

That pretty ass was so tight, tighter and tighter, till it exploded from a tiny hole to a mess full of threads and showing his hairy ass ready to be eaten by someone very hungry. His balls were getting bigger till falling down and punching the air with effect and bouncing… just to let his monster breath and grow bigger and veiny: His wonderful and juicy cock. Full of warm milk.

He was growling more, his lips full of warm spit, his tongue so hungry to eat nipples, armpits and biceps, maybe a good ass too… Turo was turning into a beast, a hungry massive BEAST.

— T-this… is amazing, fuck OH FUCK. I’m growing massive, m-my arms so — he flexed his pumped and growing biceps, his trapezoids pumping out like crazy and shoulders too till up his arms showing off hairy armpits, veiny biceps and triceps. Liking them with passion, growling more, whispering Birch and Mirror names, jerking off his cock.

Time to masturbate, to feel everything, stomping the ground with little steps, growing bigger, smashing the walls till burst them all, moaning and precumming. The smell was getting Birch so horny that he was cumming over the door non-stop till the liquid was sniffed by Turo and his cock destroyed the entire wall. Face by face, a monster 10ft taller Turo in front of a demi naked Birch holding and jerking off his cock and cumming. Then Turo started to cum covering Birch in cum, as it was a shower. Watching the scene was making him extremely horny so he flexed his biceps against, growing 1ft bigger till burst the roof and feeling his muscles as if someone was giving him a massive blowjob, but it was Birch, covered in cum, sucking his cock as much as he could. Turning the entire laboratory part in a mess, destroyed, full of sperm and sweat.

Till the very beginning of this story, when Birch was kissing Turo and eating cum from his lips.

Having a good sex in a normal size but maybe growing a bit inside Birch filling his ass like a delicious cutie pie.
