Jesse was staring at the door with a hateful rage. "Andy, we have to get home." He said barely managing to conceal any his anger. Andy was still inside quite out of breath his enlarged partially erect easily foot long organ dangling from his crotch. Jesse knocked on the door. The banging echo'd in the bathroom loudly "Andy, could. you. answer. me?" He shouted almost but not quite threateningly.
"Excuse me, sir?" a voice suddenly spoke to Jesse.
Andy recognized it as the gas station attendant.
"What?" Jesse hissed at the attendant.
"Sir, while I understand your frustration please don't slam against the door."
"You understand my frustration?! You fucking don't! and he won't come out!"
Andy whimpered behind the door. Whispering. "He's going to hurt me if I come out."
The attendant grimaced. "Sir, is this true?" Jesse couldn't suppress his rage much longer.
"I am not going to fucking hurt him if he comes out right now! but if I have to stand here much longer..."
Jesse felt a sting in his crotch again and shouted curses out loud as he grasped his crotch. The attendant stumbled back and rose his arms thinking Jesse was going to attack him. Andy despite being tired was however getting erect again as he felt his manhood getting larger again as his erection now finally stood at and absurd 17 inches. Andy couldn't help but start rubbing it again despite it still tingling somewhat sorely from the last time he masturbated. Jesse looked up at the attendant. "Don't you have a fucking key or something?" his voice being noticeably higher. "Sir, I can't just open this door for you while you are like this sir. You have to calm down. " Jesse grabbed the young mans collar. "You'll get the key." The attendant pushed him away as Jesse loosened his grip. "I won't, sorry, sir." Jesse's eyes turned especially fierce. "I'll fucking find it myself then! I'll fucking find the key and drag him home myself whether you help me or not!" He said to much Jesse's crotch stung and he grabbed it with one hand cringing painfully. Jesse found nothing there even his balls were gone. "M'am, you have to calm down." The attendant said. Jesse threw him a fierce glare and hissed. "M'am?" Jesse's own voice startled him in the process.
Andy meanwhile was moaned even louder than before as his dick felt so pleasurable that it almost hurt. As it grew he barely managed to keep hold of it and keep masturbating as his size dwarfed the rest his body. It reached 19 throbbing inches long. His panting became hastier yet deeper as he rubbed his meat. He couldn't believe how big it was. Jesse grabbed the attendants collar again. "Who are you calling M'am?!" He said with a high effeminate yet still somewhat gender ambiguous sounding voice. The attendant struggled. "Miss, I am sorry, I don't understand." Jesse saw his own arms and hands. They were less hairy and thinner more fragile looking. "What the fuck?!" He shouted. "Miss, what is wrong?" the attendant uttered confusedly. "What is wrong? I'll tell you what is wrong! I am a man!" The attendant stumbled back. "Sorry, Sir, I thought you were." Jesse interrupted him with a rant "My little brother is fucking up my life! I'll fucking make him pay some day!" Jesse felt his crotch sting again.
"What the fuck? It was already all gone!" He grabbed his crotch then felt it was different, he now instead of having nothing had a vagina. Looking down into his t-shirt he saw the hair on his chest was mostly gone but he still didn't have female curves. Feeling his hips he thought they might be somewhat wider. "Miss.... I mean... Sir... what appears to be wrong?" Jesse glared at him with intense hatred. "Don't talk to me." He said, his voice still sounding ambiguous in gender. Andy gasped as his dick felt weird again. He was just barely manage 19 inches and now it was growing bigger? He leaned back as it grew out another 2 inches supporting it best he could in two hands. He stared at it, 21 inches, he couldn't believe Jesse could have let it come this far. He continued to jerk off gasping for air and moaning. Rubbing the tip with his right while rubbing the massive shaft with his left. He went faster and faster the grip around his head tightening at first and then getting more loose again he sped up even more. Moaning and holding his breath and then just as the climax started really building it slipped out of his hands. Swinging down quickly and then continuing to swinging like a pendulum between his legs his cockhead dangling below his knees. Even while erect his penis at this size hung down as if it was just a massive flaccid dick. As it was hanging down his penis seemed to swell even more. Andy was still horny so he lifted it up and gave it what amounted to a few final rubs before he came. He couldn't even keep standing as he practically collapsed onto the floor. His swollen dick dripping over one of his tights.
