Peter and his wife Felicity sat in their reserved seats in the carriage, waiting for the train to leave Kings Cross. Their conversation was interrupted by the sound of young female voices, laughing and giggling outside in the corridor. The door to their compartment flew open and in walked four scantily clad young girls, chattering away excitedly. They stopped as they spotted Peter and Felicity and then one of them said "Okay, so who's got the short straw sitting next to gramps?"
As they all checked their tickets, a slim brunette said, "Looks like it's me Sasha." At which she sat down next to Peter and smiled.
"Hi," she said, "my name's Susie and these three losers are Sasha, Cindy and Kat."
Peter was quite bemused by the introduction and introduced himself and Felicity, who just about managed a smile in the girls' direction.
"You'll have to excuse Fliss," he said, "she suffers from travel sickness and isn't the best company on these journeys." Turning to his wife, he asked "Do you want your sleeping pills now honey?"
She nodded yes, and he reached into his pocket and extracted a small box, handing it to her. She took two tablets from the packet and swallowed them with a swig from a water bottle she was holding, before handing the box back to her husband.
"That's it love; you'll be sparko in no time." said Peter as Fliss reached into the bag at her feet and removed a small travel pillow, which she placed behind her head.
By this time the train had started pulling out of the station. The three girls sitting opposite Peter had begun to chat amongst themselves and Susie had got a compact mirror from her bag and was checking her make-up.
Peter opened up the paper that was on his lap and began reading. He had a long journey ahead of him and, with his wife out for the count, wasn't envisaging any stimulating conversation with his fellow travellers.
His reading was frequently interrupted by giggles from the girls and he would occasionally glance over at them to check out what they were up to. They appeared to mainly be looking at things on their phones, sometimes showing the other girls what they were looking at.
About a half hour into the journey, he looked across at the girls for the umpteenth time. This time his eyes were transfixed; all three of them were sitting with their legs splayed apart and with the short skirts they were wearing he could see all three pairs of knickers. The girl sitting opposite him was Sasha and her knickers were so tight he could make out her camel toe.
"Enjoying the view," asked Susie, as she noticed a quickly developing bulge in Peter's trousers. The other three girls all giggled at this but made no effort to cover themselves.
"I uh .... I was ... Umm ... I was thinking about something..." said Peter.
"Yeah and I can see exactly what you were thinking about," said Susie. "So, is the missus out for the count for a while?"
"She'll be dead to the world till we reach Edinburgh" came the reply.
"Oooh, I was hoping you'd be going all the way," chipped in Sasha.
The other girls all laughed at this as Peter lightly blushed. He tried to return his attention to his newspaper but felt a hand on the crotch of his trousers.
"Poor thing looks trapped in there," said Susie, "How about we give it some room to move."
At this she reached for Peter's flies and unzipped them, putting her hand inside and surfacing with his semi- erect cock. She stroked it lightly and it twitched and hardened under her touch. The other girls were all watching excitedly, wondering how far Susie would go.
"Looks like you were wrong about the short straw Sash," said Susie, "Quite an impressive one if you ask me. I wonder what drink I can get if I suck it."
At this she lowered her head and took the tip of Peter's cock between her lips.
"Wow, pre-cum already- you were getting excited, weren't you?" said Susie, before returning her mouth to the task quite literally in hand.
Cindy got up and pulled the blinds down on the internal windows and the door to prevent any passers-by from seeing what was happening in the compartment and then returned to her seat, where she proceeded to stroke herself through her panties. Looking along the seat, she could see that Sasha and Kat were already working their pussies with their fingers. She smiled, "Looks like it's not going to be a boring journey after all girls," she said.
Susie was now working her head up and down the thick shaft beneath her, taking more and more of it into her mouth with each descent. Peter's left hand had entwined its fingers in her long brown hair, stroking her head as her mouth worked its magic on his cock. He was groaning and closed his eyes to savour the pleasure of this unexpected blow-job.
He heard other moaning coming from one or more of the other girls and opened his eyes. He was treated to the sight of all three of them stroking themselves. This caused a further moan to emerge from his mouth and he involuntarily licked his lips at the sight before him.
Sasha, who was immediately opposite, noticed his tongue and pulled her knickers to the side, exposing her shiny wet lips.
"You can use that here when Susie's finished with you," she said, watching Peter's face as she slowly inserted a finger into her hole.
"Oh fuck," said Peter as he strengthened his grip on Susie's head and pushed her mouth down hard on his cock.
Looking across at the window seat, Peter noticed that Kat had lowered the straps of her top and was playing with her breasts with one hand whilst continuing to stroke her pussy with the other.
"Gorgeous," he said as he eyed the small, pert breasts being squeezed.
Kat looked over at him. "Would you like a suck?" she asked.
Peter nodded eagerly, and Kat rose and walked across to him, bending her upper body forward above the pistoning head of Susie. Peter opened his mouth and took Kat's left nipple between his lips and sucked; he removed his hand from Susie's head and grabbed Kat's right breast, squeezing it as if trying to extract some milk. Kat placed her hands behind his neck and pulled him further on to her breast.
"That's it grandad," she said, "They're only small, see if you can get the whole thing in your mouth."
Peter opened his mouth as wide as he could and was rewarded with a mouthful of warm, soft flesh, which he sucked on and worked his tongue over.
"Mmmm," said Kat, "you're good. And good boys get rewards." With that she extracted her breast from his mouth and pulled away. She reached down and pulled her knickers to the side exposing her clean-shaven pussy to his gaze before returning to her seat where she resumed pleasuring her pussy while staring at Peter's cock as it appeared and disappeared in Susie's mouth.
Susie removed her mouth from his cock and began to stroke it, using both hands.
"Come on daddy, give me your load," she said.
