My Futa Academia: Chapter 5 - A helping Hand

Toru Hagakure has gotten a growth spurt, making it much harder for her to jerk her massive invisible futa cock. Yuga Aoyama decides to lend her a helping hand, but finds out too late he got in way over his head.

Notes:

This was a shorter one, just to let you guys know

------------------------------------------------------------------------------------------------------------------------------

Yuga Aoyama massaged the muscles of his jaw as he walked down the hall. Having to wear the U.A. High School mandatory ring gag was really starting to take its toll. He just hoped he wouldn't start developing any wrinkles on his beautiful face.

''At least I can take the stupid thing off during lunchbreak.'' he sighed as he rounded the corner.

To his surprise, he found Toru Hagakure, the Invisible Girl, in one of the empty classrooms. Or at least, he saw her clothes floating in mid-air, which was about as far as you could really 'see' her.

She was standing by a desk, backpack on the chair, as her sleeve rapidly moved up and down. Yuga blushed as the realisation hit him that Toru was jacking off. Despite having no visible facial expression, Yuga could tell from her body language that she was having trouble.

''Excuse me, Toru?'' Yuga said as he entered the room.

''Eh?!'' Toru yelped in surprise as she saw Yuga enter the class.

''Is something the matter?'' Yuga asked.

''Uh, w-well…'' Toru stammered awkwardly.

''Well, I got a growth spurt last night, and my dick has gotten much bigger. It wouldn't be that much of a problem, but I also keep having this hard erection, and I can't get it to go down.'' she explained shyly.

''You know, I could help you with that…'' Yuga suggested, a devious twinkle in his eye. Toru gasped in shock.

''No way! My cock is huge now! I can't even fit both my hands around it.''

''Oh please, how big can it be?'' Yuga rolled his eyes.

He got his answer rather quickly. Toru let go of her dick, and the invisible shaft of meat came down onto the desk with a 'thunk' so loud it made Yuga's heart skip a beat. He stared in shock as the wooden desktop showed signs of straining under the weight of the see-trough cock, showing little cracks in the middle.

''…On second thought, I don't think I got the time…'' Yuga desperately tried to back-paddle.

''Ah ah, no take-backsies. You offered your help to a lady, now you got to see it through.'' Toru said, sounding a lot more authoritative all of a sudden.

''Get on all fours.'' She commanded.

''Y-you're not even going to let me lube it up with my saliva?'' he gulped.

''Yuga, if I were to put this thing in your mouth right now, I would break your jaw and tear it off your skull. I'm doing you a favour by going through the backdoor.'' Toru explained.

Yuga trembled as he got on the floor, nervous sweat dripping down his naked skin. He got on his elbows and knees, hoisting his large fat butt into the air, presenting it to his invisible superior.

Toru grabbed her invisible shaft and prodded the tip against Yuga's asshole. Yuga whimpered in fear as he felt the huge veiny stick of meat rub and prod against his ass. The fact that he was unable to see the instrument of his doom was only filling him with more dread. He then felt Toru's hands firmly grip his hips.

''Alright, brace yourself, I'm going in!'' she declared. With a quick, firm thrust, she shoved her massive dick into his tight asshole.

''Aaah!!!'' Yuga cried out in pain. The cock was without a doubt the largest thing he had ever taken up his ass. He was fairly certain she had the biggest dick in the entire school at this point, save for maybe MT Lady, although only because the Social Studies teacher had size-shifting powers.

He moaned and panted as the invisible girl rocked her hips back and forth. Her giant invisible ball sack slammed against his ass as her cock stretched his asshole wide, her invisibility making it so anyone watching from the back could look far, FAR into Yuga's insides.

''Sacre Bleu! You're tearing me in half!'' Yuga begged for mercy as tears streamed down his face.

''Sorry Aoyama! I can't stop now! I'm almost ready to cum! Just hold on a little longer!'' Toru moaned as she smacked harder and harder against Yuga's fat girly butt.

''P-please! Mercy, mercy!'' Yuga groaned, his voice low and coarse as consciousness began to slip away from him. Toru paid him no heed as she kept selfishly using him as a disposable ona-hole.

''Please…merci, merci…'' Yuga gagged and gurgled as his eyes rolled back in his skull.

''A-ah! C-cumming!'' Toru moaned loudly as her cock twitched sporadically, rope after rope of thick hot semen pouring out.

Yuga groaned in discomfort as her potent seed filled his stomach to the brim, then gagged as it kept pouring in, leaving his stomach and rising up his throat. He retched and gagged as the torrent of sticky white liquid poured out of his mouth all over the floor.

Toru panted heavily as her cock began to grow softer and shrink slightly. Still, it took her some wiggling to pull it loose from Yuga's asshole. As it popped loose, a wave of cum came pouring out the poor boy's gaping asshole. It was stretched so wide, it looked like it might never be able to please another girl ever again.

''Ooooh, wow! That felt so good! I think I'll use your butt again if I need help, 'kay?'' Toru said cheerfully. Yuga just panted painfully.

''Yuga? Yuuugaaa?'' Toru called out to her friend.

''Merci…merci…'' Yuga moaned, mindlessly licking Toru's cum off the floor.

''Oh jeez! I went overboard again! I broke the poor thing! Midnight is going to kill me!'' Toru panicked.
