The lunch bell rang and before anything else she went to the bathroom, as she needed a piss and had been holding back for some time. She entered the ladies room and headed to a stall, which she entered and locked the door. She entered the ladies room and headed to a stall, which she entered and locked the door. She then unbuttoned and unzipped her jeans, stuck her dick out, aimed at the toilet and relaxed her muscles and let her piss out. She enjoyed the relieving sensation of emptying her bladder, and once she was done pissing she shook her cock to get rid of the last few drops.
"Well, well, who would have thought that the great beauty of the school had such a big dick." Kelly froze at the sound of someone talking before she could tuck her dick back into her pants. She searched for the source of the voice and found a girl leaning over the partition with the neighboring stall. She wasn't close to this girl and all she knew was that her name was Samiya.
"Please don't tell anyone about this." Kelly said without thinking
"Maybe I'll keep your secret, but you'll have to do something in return." Samiya said
"What do you want me to do?" Kelly asked
"Here and now we will not have space and time. Go to this address after class, I'll be waiting for you. If you don't show up, everyone at school will know your secret pretty quickly." Samiya said and handed Kelly a note with an address. She then winked and disappeared on the other side of the partition.
Kelly tucked her cock back into her pants and waited a bit until she was sure Samiya had left the bathroom. She couldn't accept that someone had discovered her secret.

Seeing no alternative, Kelly went to the indicated address after class, arriving at a relatively large house. Whoever lived there might not be very rich, but he still led a comfortable life. She rang the doorbell then Samiya opened the door wearing nothing but lingerie.
"It's about time. Come in, today we have the house to ourselves." Samiya said
"Do you live alone in such a big house?" Kelly asked after she walked in and Samiya locked the door.
"Of course not. My parents are traveling for work, my brother went to play at a friend's house and is going to sleep there, and my sister went out with her boyfriend. Knowing her it's almost certain that she won't be coming home today." Samiya said "Now forget the others, today you are all mine." she said and grabbed Kelly's dick through her pants.
Kelly tried to escape, but Samiya said she would spread her insurance if she didn't let her do what she wanted, and she was forced to let her dick be caressed by the other girl. Inevitably her dick ended up getting hard, and that was what her schoolmate wanted, so she unbuttoned and unzipped her jeans, pulling them down and admiring the boxers stretched to the limit by her erection.
Samiya lowered Kelly's underwear and stroked her cock some more, watching the precum that ran down it before starting to suck it.
Kelly couldn't deny that she was enjoying it, and deep down she really wanted to go further. She imagined herself fucking Samiya, but remembered the other time when she lost her friends when they became dickgirls after being fucked by her. Samiya didn't know this and she feared the same thing would happen again and what could come if she changed too. She tried to warn, but not knowing how to explain so that the other girl would believe her, so she took too long and when she realized she was already going to come. Samiya also noticed the approaching orgasm and took the cock out of her mouth, stroked it some more making her come and letting the cum hit her face.
Samiya didn't even bother to clean up. She took Kelly to her room and ordered her to undress, the same as removing her lungerie. She then forced Kelly to lie on her bed and sat on top of her, rubbing her pussy against the dickgirl's now flaccid cock, making it hard again.
Realizing what Samiya wanted, Kelly tried to stop her by telling her the story her mother had told about her and what had happened to her old friends, but the girl didn't believe it and still said "That can't possibly be true, and even if it is, I don't think it would be a problem if I grew a dick." and she descended on her cock, burying it in her pussy.
Kelly then, knowing she couldn't help it, didn't hold back either and fucked Samiya in order to achieve maximum pleasure. She noticed how wet she was and very different from when she fucked Anna and Tina, and decided to enjoy the exoerience more as if the same thing happened to her high school friends soon that pussy would no longer exist.She then took control and turned around, forcing them to reverse position and Samiya to lie on the bed while she fucked her hard. The girl accepted the change of domain and feasted and moaned as she was fucked, having two orgasms before Kelly finally came inside her.
"I fucked you like you wanted, now don't blame me for what's going to happen to you." Kelly said
"I've already said that I don't believe your story at all. Okay, I feel different from the times my old partners came on me, but that's because your dick is bigger than theirs. No way that's going to grow a dick on me." Samiya said
"It's the same thing my friends said back then, but none of them liked what came next." Kelly said
Samiya wasn't convinced anyway and a few minutes later a cock came out of her pussy, which soon after inverted into a ballsack that was filled with her new testicles. "I can't believe this actually happened, my pussy is gone and now I have a dick. That's great." she said, as she had loved the change she had gone through. She got up and opened a wardrobe door that contained a mirror on the inside and admired herself, seeing her figure with his hard cock between her legs. "What do you think? Am I not sexy as a dickgirl?" she asked Kelly
"It looks good on you. But, aren't you mad at me for that?" Kelly said
"Me mad at you? No way. In fact, I loved it." Samiya said. approaching Kelly and comparing the size of their dicks, seeing that her newly grown dick was slightly larger than the other girl's, a difference that couldn't have been more than half an inch.
Samiya then wanted to debut her new dick and asked Kelly to have her back to her, so she positioned and started fucking the other dickgirl's ass, who was surprised because it was the first time she was fucked by someone. This being her first time playing the male role, she was inexperienced, and with that she came too quickly.
