Andy crawled out of the car and stumbled toward the gas stations doors holding his crotch. His zipper was about to give, he bladder was being crushed by his tight underwear and he could feel his clothes dig into his skin. He let go of his crotch for a moment and uncomfortably walked into the the gas station his bulge sticking out very noticeably and to his dismay saw no toilet. He asked the gas station attendant. “Where is the toilet?” The gas station attendant was a bony looking fellow in his early twenties with a company cap. “Ah, it's out back.” He rustled around under the desk with his hand. “Here is the key, give it back when you're done.” Andy thanked the attendant and turned around with the key in hand. His zipper finally gave. “What was that?” The gas station attendant wondered out loud. “Sorry, that was me, it was nothing.” Andy looked down and saw his bulging underwear poking out between the zippers.
He reached the toilet and opened it rushing in and slamming the door behind him. It was a simple but surprisingly clean toilet cabin that reeked of bleach with ax with a single toilet, a single urinal and a washing bin. His trousers where so tight that he couldn't get his dick out, it took quite a painstaking effort to unbutton but then he finally got it out. Andy didn't have time to marvel at his flaccid manhood. The urinal was so high and his manhood so long that he had to lift his dick quite high to piss into it. A powerful stream flowed out of his manhood and he sighed in relief. When finally relieved he looked down at his dick even flaccid it was now about 9 inches long, it looked significantly nicer than his former flaccid, heck it looked nicer than his old erection. It kept dripping so he shook it a bit from side to side. He started getting horny. He looked at the door, it was fully sealed nobody could look into the toilet from the outside and the door was locked.
Realizing that they had been the only car to have pulled over here he decided to jerk off. Jesse couldn't stop him and he could say he had to take a shit as well anyway. He started rubbing his long shaft and wiggling it around some more. He felt it took a quite a big amount of time in to get hard with this monster but his comprehension of time quickly started to fade. 10 inches, 11 inches... 12 inches... 13 inches. He lustfully looked at his intimidating manhood. It looked so amazing it's proportions far superior to Jesse's old manhood. He kept stroking it, and stroking it, and stroking it. His breathing becoming quicker and his shaft feeling hard in his hands.
Suddenly Andy realized that there was someone pounding on the door. “What are you fucking doing in there!? It's been HALF A FUCKING HOUR.” Jesse screamed from the other side Andy didn't even hear him the first time he called. Andy while still pleasuring himself answered but accidentally with a unmistakeably horny tone. “What the fuck? Get out of there! You better not be doing what I think you are doing!” Jesse yelled. Jesse than yelped as his crotch stung again. Andy's crotch now uncovered felt warm Andy saw and felt his shaft lengthen and moaned from the experience and started to rub his growing shaft as fast as he could despite already being fatigued and just as his manhood reached 15 inches long he came a thick squirt of semen shot into the urinal and then again... and then again... On the other side of the door he could hear Jesse groan. Presumably with his hands on his own 1 inch long manhood.
