Sandy grabbed Callum by the hand and led him to the boy's toilet. Surprisingly, the place wasn't as pungent as she had hoped but there remained the faint scent of piss. She continued to pull him to the farthest and larger stall and locked it behind her. No one would see them here, especially when the school didn't skimp out on extending the walls down to the floor.
Sandy looked at Callum's widened eyes. He must be thinking all sorts of questions about why Sandy's little brother dragged him to the boy's toilet. Sandy thought he was smart enough to realize she'd say something of the utmost secrecy. With him waiting for something to happen, Sandy removed her clothes which surprised Callum even more. He was about to leave the stall when he saw the zipper running along Graham's back.
"Open it," Sandy whispered.
Intrigued, Callum held the key and slowly pulled it down. Sandy could feel Graham's flesh parting away, separating the more teeth the key passed. Graham's flesh hung heavy and they slid out of her face and torso. They hung loosely around her waist.
"Wha- Sandy? Is that you?" Callum said in a loud whisper. "You looked exactly like your brother. What did you d–" He was about to continue his questions when they heard the door creak open. They waited until the person finished taking a piss and left the restroom.
"He didn't even wash his hand. Gross." Sandy said with her voice again. "And yes. I was my brother. There's this zipper that turned him into a skinsuit I can wear, and I've been him since this morning. And if you're going to ask, I saw his dick and I wasn't impressed. I'm now open for further questions."
Callum's mouth hung open for a moment before calming himself. "I was about to ask that question, and thank you for asking promptly. As for my other questions. What the fuck!? What you did to your brother was both amazing and terrifying. Did he know he was going to be turned into that?" Callum pointed at the hollowed-out flesh hanging around Sandy's hip. "Can– can I also turn into that?" He gulped.
"No. My brother didn't know. I turned to him when he was asleep. And, yes. I can peel the zipper from my brother once I turn him back and stick it on you. I can wear you just as easily."
"Please, don't. I'm still fond of being myself, thank you very much."
"Well, I have no intention of turning you into a skinsuit any time soon. I'm still doing quite decently as my brother, but it has been boring so far. I learned how hungry teenage boys could be and spent his first class answering his pop quiz." Knowing her display was well-seen by Callum by now, he wore Graham again and closed the zipper. He picked up his shirt from the toilet lid and wore it over herself.
"You don't even look like you're wearing the skin of your brother. You're just… him!" Callum checked Sandy's eyes and made her open her mouth to check. He found no signs of the disguise except for the zipper running down Sandy's spine. He was about to comment on his findings when another person entered the restroom and promptly left after pissing. "I think we should find somewhere else to talk to."
They found a semi-private area to talk on the empty bleachers after leaving the restroom. They were thankful for the roof that shaded them from the sun, especially Callum, who took great care to protect his skin from the heat. The only people around were some members of the band practicing their routine.
"How do you feel so far? Being a boy, I mean." Callum shifted on his seat while pinching the skin on his wrist. This whole thing with the zipper must be getting to him. "No offense but, I think this is good on you. You've always been tomboyish since I knew you. Becoming a boy must be liberating, at least that is what I think."
"It kinda does. My mom didn't berate me for having Graham's pungent musk, even when I couldn't scrub it all the way after taking a quick bath. Boys can be messy and it'd take a lot before someone reprimanded for being so." Sandy looked at Callum's neat appearance and realized he might not be able to relate.
"I understand. I wasn't always this conscious about my appearance. I was a slob too, you know?"
"And how long was that?"
Callum chuckled. "When I was a baby. Mom said I was a messy eater."
"Idiot. That doesn't count." Sandy shifted on her seat and tugged his jeans. His dick and balls are stuffed inside there, and he had to move his legs in various directions to let them loose. Even though they were in the shade, the sun shone brightly on the zenith and made the surroundings a tad bit warmer. He could feel sweat staining his underwear.
"You said before you saw your brother's dick already. I am not going to beat around the bush with this question but have you jacked off with it yet? And if yes, how different is it from female masturbation? You might finally crack the questions many scientists have asked."
"Nope. I haven't jacked off with my brother's dick yet since I never got the time this morning. I thought of jacking off in the restroom, but it seemed like a poor place to have my first male ejaculation. Maybe when I get home…" Sandy then remembered he had to come home as herself if she did not want to get her mother mad. Just thinking about ejaculating made her borrowed dick hard. But he doesn't know where to release this pressure budding in his groin. "Fuck. I won't be able to jack off home since I think I'm in trouble with my mom."
Callum gulped. "I know a place."
"You do? Don't tell me it's the bathroom."
"No, it's not." It was Callum's turn to grab Sandy by the hand and lead her to the side of the bleachers. Callum scoured the white wall of the bleachers and his eyes widened when he found a latch. "Jackpot," he said. The door creaked open, and they hurried inside. Surprisingly, the interior was dust-free, illuminated by light filtering through holes in the ceiling. Sandy was shocked to discover that the bleachers were hollow—they had never sounded hollow during football games when students stomped their feet.
"How did you know about this place?" Sandy asked.
"Forgot her name, but one of my admirers wanted to suck my dick here."
"Did you get your dick sucked here?"
"I wanted to, but I got cold feet. She didn't ask me after that so I thought she got cold feet too. She said she's the only one who knows about this place since her uncle used to work in maintenance here. She brought her secret with her when she went to college." Callum scratched the back of his head. "Thinking back, I should have followed through. She was hella sexy and I've never received any bold invitations like that since."
"I'm surprised. I swear half the bitches in this school are salivating for your balls."
"I'm more surprised that a girl like you can say such a thing."
"Well, I'm no regular girl. I was a tomboy, remember?"
"Yeah…" Callum disappeared to the other side of the room and dragged back a chair and a box of tissues. "Here, have a seat."
"Don't tell me this is your goon cave, Callum."
"This is my goon cave," Callum said with a defeated expression. "Whenever I goon, I look up one of those holes and imagine I was looking at a beautiful cooch. If I'm a bit daring, I imagine what happens if I follow through with the request of having my dick sucked."
"Gross… You boys are truly disgusting." Sandy sat on the chair where Callum must have jerked off a hundred times. She tried looking at one of those holes but they were too far. A girl must have a big fat vagina for it to be seen in those holes. She turned her gaze back to Callum and then to her body. "If only those girls knew how much of a gooning dork you could be. They'd be surprised, Callum."
"I bet they would," Callum said, his voice quivering. "But please, don't"
Sandy unbuttoned her jeans and let the pool around her legs. It was sweltering hot beforehand, and that made her brother's underwear drenched in putrid sweat. He rubbed the bulge and felt how damp it was. Not only that, it released a thick musk that swiftly spread throughout the room.
"Damn, you weren't kidding with your brother's stench," Callum said. Despite commenting, he did not seem to reel from the smell. "Do you want me to teach you how to jack off a penis?"
"Nope. I think I got this. I watch gay porn too, you know?"
Sandy hooked her fingers around her brother's underwear and slid them off. Her cock—Graham's cock— stood semi-hard but a few quick strokes pushed it to full mast. She slid her hand up and down while glancing occasionally at Callum to see if she was doing it correctly. Callum made faces as if he was getting pinched in the nuts.
"Do you feel pain?"
"I think so… I never thought male masturbation was painful." Sandy winced when she slammed her hand.
"It shouldn't be painful. Can… Ummm… I think you need help."
Sandy let go of her dick and waited for Callum to do something. She watched as Callum drew closer and wrapped his warm fingers around her shaft before jerking it off. Somehow, having another person jerk him off felt quite heavenly. Each careful stroke sent waves across her stolen body, sending her into a deeper haze. He has done this countless times and must be well aware of the point-perfect strokes that could squeeze out most of the pleasure from this dick.
"Oh, yeah… That feels so much better," Sandy leaned back and basked in the feeling raging in her dick. Is this how boys feel all the time? No wonder they jack off a lot. This is fucking amazing! Nothing could make this be— Sandy jolted on her chair when she felt something wet and warm wrap around her dick. She looked down to see Callum's handsome face sucking her off. "Callum, what the fuck? I thought you're straight!"
"I am straight," Callum said before dragging his tongue up Sandy's shaft. It caused her to collapse back into the chair before letting out a soft moan. "You're a girl, and I'm a guy. I think this is still straight to me."
"That doesn't make sen—" Sandy was hit with another cute suckle. He could feel Callum's tongue prodding underneath her glans before swirling around the tip. His mouth was like a vacuum, and fucking hell— he was sucking her dry. What truly pushed Sandy over the edge was Callum suckling on his little marbles. Fuck! Her legs spasmed from the thorough sucking he put her dick under. Through instinct and desire, she grabbed Callum's blonde hair and fucked his face relentlessly. Callum surprisingly took every thrust. And before they knew it, Sandy shot her thick load down Callum's throat. Muffled moans sounded on her cock as he made her own sounds of pleasure.
Sandy still dripped wet with her ejaculation when Callum pushed her to the floor. She heard him shuffling and when she looked, she saw Callum had removed his pants. He spread Sandy's cheeks and licked them wet. "Mmm… you've got a delicious boy pussy, Sandy."
Still reeling from her load, Sandy could only nod weakly. Callum was about to fuck her and she was too weak to protest. No… She– she wanted this. She might not love Callum as the other girls, but she was always fantasized about getting fucked by him. The only difference was, she never thought it would happen while she looked like her younger brother.
Callum pushed his hips forward and Sandy felt as if she was breaking apart. She clenched her fist and gritted through the pain. Their bodies rocked with every thrust, sending both of them into intense euphoria. To her surprise, each push of Callum's thick cock sent waves that made her cock harden again. She merely came here to learn how boys jerked off, but she experienced something more than she had hoped.
"Fuck me more, Callum." Sandy said.
Compelled by her commands, Callum fucked Sandy harder and faster. They groaned in pleasure and pain, their moans fused into harmony. The intensity grew between them, and they were soon thrown into their peaks. Callum made his deepest thrust yet and burst his seed inside Sandy's rectum. At the same time, she emptied her second load on the floor. Thick and copious, semen splattered on their bodies. They were drenched in sweat and embraced by their shared aromas.
Callum's hips slowed down and he slid out with a pop. Sandy thought Callum was going to kiss her, but it seemed this might be too gay for him. Not that she cared.
"So, which masturbation is better?" Callum breathed. "A man's or a woman's."
"You idiot. You tampered with the methodology when you decided to suck my brother's dick and fucked me in what you called a "boy pussy". I always had this feeling you were going to do that." Sandy picked up the box of tissues and wiped the mess they had made. She was about to clean up Callum when she saw how massive his cock was. She only had a feel of it earlier, and now she could see its sizable length from the pilfered light above. She could not believe she took that in, with his brother's tight asshole no less.
"Sorry. I better leave you to jack off alone in the future. I just… I haven't had a decent jerk off in a while, and I'm sorry you had to see that side of me."
"Well, it's done. Now help me clean ourselves. We still have classes and we can't go smelling like cum."
They cleaned themselves afterward by taking a shower in the school gymnasium. Luckily, Graham packed extra clothes in his locker and Sandy still knew his code. It was 0513 because it was his code for Friday the 13th. "What a fucking cringe," she said under her breath while he scrubbed her dick and balls.
