Unfaithful - part 2 Mark had shown up being his normal cheerful charming self and making her feel guilty beyond belief and now the two of them stood waiting on the platform. "This will be so much fun..." he said, "...there's supposed to be a restaurant, a pub and even a small movie theater on board." He was standing close to her with his strong arm around her and she couldn't believe that the night had turned out the way it had. She really had everything she wanted hadn't she? She leaned her head against his chest closing her eyes for a few seconds. They heard the train arriving and as on a queue the girls together with Sean seemingly out of nowhere appeared next to them. She avoided Rosin's look and quickly followed Mark as they boarded the train. The corridors were a little narrow and the train, with most passengers already on board, was quite crowded. Sandy was way too preoccupied to be able to make out the number system of the compartments but Mark was thankfully very good at those things. It was hard enough for her just to keep up with his broad shoulders in the state she was in and that was what she was doing when suddenly finding her way blocked. She looked up and into a pair of sultry dark eyes openly checking her out. The woman was really beautiful in a kind of Hispanic way and the sensuous but superior air around her was catching Sandy completely off guard. "Please...let me through..." she almost whispered as she averted her eyes. It was like the woman was undressing her with those intense eyes but she really couldn't take it all in. Was the woman a lesbian? And was she really someone that could turn...a dyke on? They stood like that for a few seconds until the woman finally turned. But Sandy had to turn as well when passing and the inevitable contact nipples to nipples were almost electric. She somehow managed to move past and continued hastily. She had to get out of there. She had to get back to Mark. "Well hello again..." Mark had disappeared into what must be their compartment and of course the four girls had to be next to them and now Roisin stood in the doorway watching her. Sandy opened her mouth to say something when suddenly she felt the girl's hands on her hips pulling her forward. Loosing her balance she stumbled into the compartment. The girl spun her around with surprising force and then she felt two arms slipping around her from behind. Soft and slender hands started to cup and squeeze her breasts in the most amazing way. But she couldn't go along with this with Mark just next door! "No...please don't..." she whispered as she automatically took hold of the shelf over the seats for support. She couldn't help but to moan as Roisin began kissing her neck while pressing her perfect small breast against her back. Glancing sideways she could see their images in the window leading out into the corridor where Mark could turn up any second now. The surreal vision of her holding her hands against the shelf for support and the girl behind her reaching down and begin to pull her dress upward was so unreal. It was like she was watching herself from the outside but the violent feelings roaming inside her body and the girls hands and lips told the truth. It was really happening and she was doing nothing to stop it. The short encounter with the librarian was nothing compared to this. It was like her most secret, wildest lesbian sex dreams coming true and as ashamed as she felt she also realised that this maybe was a once in a lifetime opportunity. She caught a sudden movement out of the corner of her eye and terrified she turned her head expecting Mark to stand there. But it was the three other girls entering the compartment one-by-one. No words were said, the girls had obviously done this before. Eager hands gently eased her down on to the seat and she closed her eyes feeling soft wet lips and delicate fingernails started to caress her body. All that mattered now was the sensual touch of the pretty teenagers' hands moving all over her sensitive skin. Her dress was skilfully removed and then her panties were being pulled down over her legs once more. Ailin, the redhead, was up on her knees between Sandy's legs and she stared like crazy as the young girl's cute freckled face moved forward, closing in on her open sex. Ciara, the blonde and Eithne, the raven haired was by her side helping each other undo her bra. Her breasts were released and soon her rock hard nipples were each covered by a delectable mouth. Anyone passing by in the narrow corridor would have seen them but Sandy was so beyond caring now. Rosin was standing behind her two friends unbuttoning her jeans while watching her friends get to work. Ailin had started to eat her now and the young girl's tongue was doing wonders between her legs alternating between kissing her clit, sucking her outer pussy lips and licking her anus opening. Then Roisin was done undoing her jeans and she quickly stepped out of them pushing her panties down in one fluid movement. "God you're so sexy..." Rosin mumbled and then she straddled Sandy's face like it was the most natural thing in the world to do. For the first time in her life found herself with another female's pussy in front of her face and it was the prettiest thing she had ever seen. Seconds later she tasted it as well. * `Better tell me when you use the bathroom next time honey, wouldn't want to loose you :). I'm off to check out the movie theatre. Be right back. Love you. Mark.' The note seemed so normal and reading it made her feel so bad. He must have gone in the opposite direction otherwise he would for sure have seen her and the girls. "God...what am I doing" she mumbled as she looked out over the rapidly darkening landscape moving by outside the window. She had started on a very dangerous path and she was only too aware of where it might lead to. She could try and convince herself that the three encounters had been unwilling but they really hadn't. Being taken like this was like nothing she had ever experienced before. The submissive feeling coming over her when first the man in the library and then the man on the train station had taken her...fucked her brains out...had totally blown her mind. It was so much not her but it was also the most exciting thing she ever had experienced. The four teenage girls was a completely different story; so weird and kinky and far out. So different from being fucked by a man yet so much the same. She had made Rosin come and Ailin had made her come. She had an idea that Mark would...like approve of her doing it with the girls. She knew two women together turned him on. But the two men...she would never ever willingly admit that to him. But the man from the train station was probably on the train and she just hoped she wouldn't bump into him again. She felt an overwhelming need to freshen up and after bringing out a fresh pair of panties she headed for the public rest room. * The vision of Roisin with just her top on and spread legs breathing hard due to the orgasm she just had given the girl was dancing in front of her eyes as she splashed her flushed face with water. She was in the rest room watching her self in the mirror, unsure if it really was her she was seeing. Her skin was still sweaty due to the intense lovemaking and her violent climax induced by the three other lovely teenagers and her eyes had a new, aroused but almost frightened, look in them. Her panties had been embarrassingly wet and the new ones already felt soaked. "This got to stop now" she mumbled and braced herself to go back. She opened the door only to find her way blocked again, this time by Ciara and her brother. She had had the petite blonde sucking on her nipple just minutes ago and now the girl apparently wanted more. And so did her brother. "Om my god...please ..." Sandy whimpered. Her sensible self screamed at her to get the hell out of there but her body was betraying her and she immediately gave in to the inevitable. Ciara gently pushed her backwards and down onto the toilet seat while Sean closed the door. "Not again..." she weakly tried protesting mostly for show. She was to exhausted both mentally and physically and could do nothing to strop them. Sean was so close now kneeling down beside her. He had put his left arm around her neck cupping her breast with one hand while the other one slowly stroked her stomach through her dress. Ciara was standing by the sink watching them and the excitement showing in the girl's sweet face made the cute teenager look so...delectable. "Told you she was up for it" the girl said in a low voice watching them with lust filled eyes and it wasn't until then that Sandy realised the real kinkiness of the situation. Ciara seemed to be turned on by watching her brother do it. The normal thing for the teenager would have been to leave but the young girl stayed put following their every move. Sean's tongue opened up her mouth and she sighed and closed her eyes feeling his hand slide even lower. In under her dress it went and she instinctively lifted her butt making it easy for him to pull down her new pair of panties with one powerful tug. Then he let goof her and she opened her eyes again seeing him shift position and start to undo his belt. Soon his cock, looking so hard, was out in the open and she stared like crazy at the male love muscle. "Lick it..." he whispered, "...make it real slippery and nice..." Before she had been passive all the way, apart from licking Rosin's pussy but now there was no turning back. If she did this it would be like 100 % cheating. She was aroused beyond belief now and still she hesitated. She had never gone down on a man before not even with her husband. But he was holding her by the neck, so strong and determined, and without knowing how she found herself slowly lowering her face towards his manhood while parting her lips to give him room. "Oooh..." he gasped as her tongue came in contact with his cock head. It tasted salty and strange but at the same time so good. She gradually let more and more of him slide into her mouth almost passing out when feeling him fill her up. Then she pulled back slowly letting him slide out again. "Oh god...that's so hot..." she heard Ciara whisper and the girl's obvious excitement somehow made her bolder. The girl wanted a show and she was going to get one. On and impulse she gathered as much a saliva as she could in her mouth and then parting her lips just an inch away from his head she let her spit dribbled down onto his sensitive skin. She encircled him with her hand feeling his shaft, slippery from her saliva against her palm for a few seconds before starting to stroke him. It wasn't until then that she realised that Ciara, now topless had moved forward. Leaning in over Sandy's head the girl started to kiss her brother feverishly letting him cup her small breasts as she opened her mouth wide for him. `This is just too weird...' Sandy dimly thought before closing her lips around his cock again. She started to suck him hard to the sound of him and his sister kissing moving her head rapidly and in less than thirty seconds she felt his hands on her shoulders stopping her movements. "Oh god...fuck...that's enough..." he panted, "...Let me just..." He didn't finish the sentence. Instead he guided her up onto the toilet and positioned her on her knees. She came in perfect position for Ciara's small breasts and leaning forward while holding onto the water container for support she took one of them into her mouth while feeling Sean push up her dress all the way in under her armpits. "Use your hands baby...open up for me..." he said from behind her and at first she didn't understand. "Let me see your sexy adorable little pink anus." "Oh no!...not there..." she whispered but she did as told parting her buttocks with her hands while continuing to suck on Ciara's nipples. She hadn't had anal sex either and had never given it much thought before and she was anxiously waiting for what was about to come. "Oh my..." she heard Ciara whisper and she had an idea that the view from where the girl was positioned was quite spectacular. Sean's tongue was warm and wet and she shivered as he began coating her anus with saliva. His hands were on her freely hanging breasts, cupping them, fondling them and making her feel fantastic and then the inevitable came. His hard hard-on against her back door: probing, pressing, opening her up a little before pushing forward. "Look at that..." the girl mumbled from somewhere above. She released the Ciara's breasts moving her hands to the slender jeans covered thighs for support as the young teenager leaned over her to help her brother keep her open. Ciara was spreading her ass cheeks so wide and he was so slick with her saliva making her feel fuller than she ever had before as more and more of his cock penetrated her ass. Then he was a far as he could go stopping there for a few seconds before starting to move his hips. Nothing gentle now. His intentions was to fuck the living daylights out of her and he did just that not making her come but making her feel like a bitch in heat being mounted in the most primal way before shooting load after load up into her tight back door.
