“Well this is awkward...” said Kris, feeling his bare ass pressing into the lap of his best friend. The train had been packed, and Alex had insisted that he didn’t want to wait for the next one, so they were forced to share a seat which meant he was stuck sitting on top of his friend. Not that he was going to protest, though - wearing something so revealing and with such a giant behind, every man at the station had their eyes glued to his ass and it was making him uncomfortable, since with no panties he was practically naked no matter how much he tried to push his skirt down to hide his modesty. He had insisted on standing on the train before and at least half a dozen guys had taken the opportunity to grab a handful of ass in the packed commotion, so it was either sit in Alex's lap or continue to be groped. Plus, as much as he didn’t want to admit it, it was beginning to turn him on like crazy watching them all wanting to feel him up and fuck him then and there in public, and it was taking a lot of effort to resist putting his hands down the front of his skirt and trying out his new clit then and there. He suspected it might have been a side-effect of Alex’s wish, but he was confident his friend would have revealed something as explicit as that.

Kris tried his best to mind his own business, but hearing Alex whisper a moan from behind him, he realized he had subconsciously been grinding his ass into his friend’s crotch, which was only confirmed when he felt something long and hard pressing between his cheeks. There wasn’t any room to stand up in the packed carriage, so he was forced to press against it, feeling it’s warmth against his body. He wanted to call his friend gross, to stand up and move away, but for some reason it just felt too good. It was like there was a switch in his brain that had suddenly turned on and now a lusty fire was building in his chest... and down below. The more he tried to resist, the greater he was getting turned on, and after a couple tense minutes he was fantasizing about how great it would feel to take a cock inside of his virgin pussy then and there. Brushing his hair he turned around and whispered into Alex’s ear, barely able to believe the words coming out of his own mouth. “Ugh... if it’ll help you get rid of that thing, you can... stick it inside of me... please.”

“You sure you’re okay with that?” Alex teased. “Fucking in public? People will think you’re a slut.”

Kris sighed, rubbing her big ass against Kris’ cock to try and tempt him. “Please don’t make me ask again, dude. I... I really, REALLY need your dick. I-I can’t control it, oh god... P-please fuck me right here, Daddy!” Getting a nod of approval and unable to wait any longer, Kris reached down and subtly unzipped Alex’s fly, almost gasping as he took Alex’s thick, long rod in his hands. He hadn’t realized that it was so enormous, especially now that he was so much smaller... using his other hand to hold his ass up, he guided Kris’ dick to his vagina and slowly slid it inside, choking back a moan as he felt himself penetrated for the first time.

As he slowly bounced his hips up and down, dressed in such a revealing outfit surrounded by dozens of bystanders that could catch them at any moment, a nervous sexual fire filled every nerve in Kris' body, his mind collapsing into heavenly bliss like he had never felt before. He could feel (and hear) his thick cheeks slapping against his partner’s thighs with every thrust as he took the mammoth member deep inside of him. He brought a hand to his mouth to muffle his moans, his eyes watering in pleasure as he tried his best to hide the incredible sensation he was feeling.

“Mmfh! Mmfh! Ah!” He squealed through gritted teeth, noticing the concerned glares of the other passengers. Deep inside of his brain he was mortified by what he was doing, but his body could only think of taking cock in his body and taking a load full of semen. Minutes of intense satisfaction passed between them with Kris feeling the sensation of female orgasm countless times until Alex groaned and began to cum, filling Kris' pussy with load after load of hot, sticky, pent-up seed. As Alex's dick softened he pulled it out and began doing his pants back up.

Kris got back to his shaking legs now that it had cleared out a bit and caught his breath. “Oh, we uh, missed our stop...” he said as he watched the station pass by outside, feeling cum drip down his thighs. Reaching down he subconsciously scooped it up with his fingers and began to suck on them, not even hesitating as his mouth filled with it’s salty and sweet flavour. Alex certainly didn’t mind. After all, he’d just fucked his dream girl in public and it was divinely better than anything he had ever felt before. Besides, his grandfather didn’t even live out this way and had already caught his plane back to China. But seeing how much Kris had enjoyed himself, perhaps he could convince him to hold off on the fix for a while. After all, it was a long trip back...
