A Boy in an All Girls School

It was another day at school for Spike, girls flirting with him, a few slipping panties through his mail slot, the usual day. After class was done for the day, he had to go to the bathroom. Since he was the only boy, there still wasn't a men's bathroom, but he'd gotten used to being in places like that with girls at this point.

When he went into the stall, he noticed a hole in the panel that separated the two stalls. He could see a girl's shoes, meaning somebody was there. He thought for a moment, and said to himself, "I guess I could use a bit of relief." before unzipping his pants and poking his cock through the glory hole.

Meanwhile on the other side, unbeknownst to Spike, Topaz was on the other side when she noticed his cock and blushed, saying to herself, "I-Is that Bahamut's cock!? I can't believe he's so big!" before moving her hand to touch his cock, feeling how it throbbed in her hand. She smirked lightly and said in a fake voice, "Oh! You must be really stressed. Let me help." before licking his cock.

As he got harder, Spike moaned, "Damn, I don't know who you are back there, but your mouth feels amazing."

Topaz giggled, "If you think that's good, wait until you feel this." before taking her top off. For a girl her age, she had an impressive bust, a 36 D to be exact. As she wrapped Spike's cock in her boobs, she said to herself, "Mom's going to kill us if she finds out about this, but I don't care, I want Bahamut to be my first."

Spike continued to moan, "Man, your breasts are amazing, they're so soft, it's almost like they're pillows. If you keep it up, I'm gonna-"

Topaz told him, "Don't be afraid, cum as much as you want, you'll be getting more than just a boobjob, I want you inside me Spike." It felt strange to call her brother by his fake name, but if she called him Bahamut, he'd know something was up. As she continued to suck his cock, she sped up both her sucking and her boobs rubbing against his cock.

Soon enough, Spike was getting close to climax, "That's it, I can't hold back anymore! I hope you enjoy my cum on you!" before erupting in an orgasm, covering his sister's face and tits in his cum.

As Topaz wiped the cum off her face, she swallowed it and said, "Delicious, but now to the main event. Sorry if I'm a little too slow, but this is my first time."

Spike chuckled, "Well, I suppose if you want to lose your virginity in the school bathroom, I won't stop you."

Topaz shivered in ecstasy of what her brother said, "It sounds dirty, but I like it that way. I never thought I'd be losing my virginity in the bathroom, but it's making me even hornier." before pulling down her skirt and panties and rubbing her soaking wet pussy against Spike's massive cock.

Spike smiled, "Whenever you're ready."

Topaz pouted in her fake voice, "D-Don't rush me! I'm just nervous, it's so big, I'm just a bit worried it won't fit." before moving her pussy onto her brother's cock, moaning in both pain and pleasure, "It hurts a bit, but it feels so good! Yes, I'm a naughty girl! I need a good fucking!"

Spike smirked, "I don't mind obliging to that." before actually doing some of the work himself, slamming his cock in and out of his sister's pussy, enjoying every moment of it and said to himself, "Whoever this girl is, she's amazing for a virgin."

As Spike slammed his cock in and out of her pussy, Topaz moaned even louder, with her mouth covered so they wouldn't attract any attention from people walking by the bathroom. Soon enough, she cried out in ecstasy, "Oh fuck yes! Make me a woman Spike! Fuck me as hard as you can until I cum!"

Spike chuckled, "For a virgin, you're pretty slutty aren't you? Not complaining. I'll be sure to make you a real woman."

Soon enough, Topaz couldn't take it anymore, she had completely been overtaken by Spike's cock and yelled out, "Yes! I'm cumming!" before slamming her pussy against the panel, taking Spike's load completely, letting it drip out of her pussy. As she pulled out she told him, "Thanks Spike, I'm glad my first time was with you."

Spike pulled his cock out of the glory hole panting and told her, "My pleasure. If you don't mind, could you tell me your name?"

Topaz cringed as her brother asked her for her name. She knew their mother would kill both of them if she found out, but she didn't know how Spike would react. She gulped hard and said, "You have to keep this a secret. It's not that I don't like you, it's just... this could make some people angry at both of us." before dropping her fake voice, "Bahamut, it's me."

Spike's eyes widened when he heard the girl on the other side called him by his real name, and his eye was twitching when he realized he had just taken his little sister's virginity. He said quietly, but loud enough for Topaz to hear him, "This never happened." before zipping up his pants, and heading out of the bathroom.

Topaz was slightly worried about how her brother reacted, but pulled up her skirt and panties and putting her top back on. "I hope I didn't just traumatize him..."

Spike had made it to his room, completely ignoring the panties piled up from being slipped in through his mail slot. He laid down on his bed, face down in the pillow before screaming so loud that even muffled, every room in the hallway could hear it.

Twilight was shocked when she heard the scream and quickly went to knock on Spike's door, "Spike! Are you ok!? What's with the screaming?"

Spike said, "Go away! I need some alone time!"

Twilight started heading back to her room when she saw Topaz coming up the stairs and asked her, "Topaz, did something happen to... Spike?" Not sure of which to call him in front of his sister.

Topaz gulped and told her, "We... while we were out in the courtyard, I sort of tripped and fell on top of him and-"

Twilight shuddered at the thought of where this story was going and said, "No! Forget I asked!" before heading back into her room.

Topaz sighed in relief that her lie had gotten Twilight to drop the subject of what really happened. When she went to her room, she laid down on her bed, thinking, "What the fuck was I thinking!? Letting my older brother taking my virginity!? Am I insane!? I'm so going to Hell for this."

Meanwhile in Spike's room, he was thinking to himself, "Why did I enjoy that so much? She's my sister! Mom's going to kill us if she finds out. And yet... something about it being her got me even more excited than I already was. What the hell is wrong with me!?"
