Now I don't really consider myself a weirdo, but I know I can get a bit obsessive, and when that happens I'm prone to doing some unusual things. I'd been attracted to other women for a little while now, but had only ever got to the drunken snog stage before losing it and backing out in a hurry. Anyway, it had been a while since I'd had a liaison with either man or woman, and I was feeling decidedly frustrated.

One evening I was returning home after work - I only just managed to squeeze myself onto the tube which was crammed with commuters and found myself wedged between two suits - not my idea of fun. At the next stop a couple of people got off, and were replaced by two young girls, obviously not locals as they proceeded to talk to each other in what sounded like Spanish - though as I'm no linguist this was only a guess. As the doors closed one of them pushed right up against me to avoid being crushed, and I could feel her firm breasts against my arm. She smiled apologetically, and I couldn't help noticing how attractive she was - long dark hair, unblemished olive skin, big brown eyes and lovely full, sensuous lips. I guessed she was about 19 or 20. I stared back, oblivious to the fact that I was breaking all the rules of tube travel - never look at anyone. If you do, pretend you don't see them, and certainly don't maintain eye contact for more than a second. My behaviour obviously puzzled this girl because she raised an eyebrow and looking away, said something to her friend, and they both laughed. I blushed and looked down, but because the tube was so crowded we were still pressed right up against each other. The motion of the train meant that occasionally I would be thrown against this girl, my bum pressing against her hip, and my arm rubbing against her tits. Each time, I couldn't help looking at her, and each time she looked away, patently embarassed but helpless to move away. I did notice, however, that although embarrassed, she did secretly smiled to herself on each occasion I looked at her - enjoying the attention, I think, but unsure how to react.

The train stopped at the station before I was due to get off, and the two girls stepped onto the platform. As they started to walk away, the girl who I had been getting rather intimate with looked over her shoulder, and we made eye contact. As the doors began to close, I jumped off the train, aware I was acting irrationally, but powerless to help myself. The girl quickly looked away from me, and she must have said something to her friend, who also looked round. Feeling decidedly foolish, I thought I'd better act as though this was my stop, and walked after them towards the lift. A lot of people were waiting for the next lift to arrive, and I stood opposite the two girls, occasionally looking up to see one or both of them staring at me. I would just smile back enigmatically, wondering what the hell I was doing. Eventually the lift arrived and we got in, caught in the crush yet again. This time, it was the other girl I was in close proximity to. She was shorter and more curvaceous than her friend, with blonde hair - but just as pretty. As people crowded in behind me I was pushed up against her, our breasts brushing together, faces inches apart. She said something under her breath in Spanish or Portugese and I could have sworn that, just perceptibly, I felt her rub against me, felt the slight caress of her hand against mine, before we both moved away slightly. I was getting quite excited by all this unexpected frottage, and started thinking quite dirty thoughts to myself, wondering what this girl would look like in just her underwear, wondering how she would react to my hands on her arse, my mouth on her nipple, while her friend watched us. The lift doors opened. The two girls made for the exit, and I felt compelled to follow them. They turned out onto the high street, with me a few yards behind. They were laughing and chatting away, seemingly oblivious to the fact that I was almost stalking them. Soon they turned off onto a quieter road with not so many people about. As I trailed them, I realised this was getting a bit ridiculous - what was I doing? And what would I say if they confronted me?

A couple of minutes later, they arrived at what was clearly their destination, opening the gate to an old Victorian house as one of the girls looked in her bag for keys. As I walked past, the shorter girl saw me and, with a look of surprise on her face, spoke to her friend who also looked up. I pretended not to see them, but as I continued on down the street, the shorter girl said "Hey, why are you following us?"

I froze, now at a loss as to what to say. I turned around, expecting them to be angry, but found that they were both smiling. As the taller girl unlocked the door, the other said "Well, do you want to come in, stalker?" in heavily inflected English.

"Thanks" I stammered, and again, not quite sure what I was getting myself into, I turned around and walked toward the house. I smiled at the girl, who gestured me to go in. As I did so, she patted me on the small of my back, her hand resting there a second too long than was necessary.

The first girl had disappeared into one of the rooms, so I turned to the other, who had come up behind me.

"What is your name?" she asked. "Belinda" I replied with a nervous smile. "Well, Belinda, do you often follow strange girls home?" but with a smile on her face. "To be honest, I wasn't following you" I lied, "I live just around the corner".

I don't think she believed me, but she nodded. "My name is Conchita and my friend is Helena" she continued. "We think you are very strange. Strange - but pretty also". She said this while looking straight at me, her eyes wandering over my body in an overtly flirtacious way. I returned her gaze, feeling slightly weak at the knees as my heart pounded. I looked away, and saw the other girl, Helena, through the doorway. She was getting undressed with her back toward me. I watched as she unbuttoned her blouse and slipped off her jeans so she was wearing just a black bra and skimpy thong. She had a gorgeous body - slim and tanned, with long smooth legs and an incredibly sexy arse. She reached round to unclasp her bra and then turned around. She had beautiful tits - surprisingly big for such a slim girl. She saw me watching her, and walked out of the room, then disappeared from sight.

"She is having a shower I think" said Conchita, quite close behind me. I felt her hand on my shoulder. As I turned around she moved in towards me, and suddenly we were kissing. Conchita certainly wasn't shy, and as our lips met, I felt her tongue flick inside my open mouth. She pushed me up against the wall, our breasts pressing against each other, just like in the lift. I pulled her into me, our kissing getting more and more frantic, and I could feel her hands on my body. She began unbuttoning my blouse, and before I knew it I was in my underwear. Conchita quickly took off her clothes until she was wearing just bra and knickers, then led me to the couch. She sat down, legs apart, and I knelt in front of her, kissing the inside of her thighs, trailing my wet tongue upwards towards her sweet smelling pussy. As my mouth reached her knickers, she pulled them aside to reveal a neatly trimmed, dark blonde bush. I began licking her swollen lips, soaked in her juices, then parted them with my fingers to push my tongue up inside. She sighed as I found her clit with the tip of my tongue, and pushed her cunt into my face, her breath coming fast and shallow. As this lovely Spanish girl writhed in front of me, thighs wide apart as I lapped at her soaking pussy, I thought to myself "What are you doing!!!" but I was too turned on to stop now. Suddenly I felt a hand on my back, then someone tugging down my knickers and removing my bra to let my tits hang free. I knew it had to be Helena. She knelt behind me and cupped a breast in each hand, her fingers teasing my nipples until they became erect. She pressed her crotch against me, doggy style, and I opened my legs and pressed my arse backwards, increasing the tempo of my cunt licks as Conchita gyrated against me. My own cunt was dripping now, and I felt Helena's tongue on it. I shivered as she lapped at my slit, then sucked on my swollen clit. She moved her tongue up to my asshole, and as she licked at it, she slipped first one, then two fingers into my fanny. This was driving me wild. I felt really dirty and was prepared to do almost anything. Pushing Conchita's knees behind her ears, her lovely pink asshole came into view, just below her gaping cunt. I tentatively touched it with the tip of my tongue, then quickly made it all wet and slippery with my saliva . She whimpered, and began massaging her clit as I licked out her anus, and soon she came, her asshole spasming as an orgasm ripped through her. I came pretty soon afterwards, as Helena finger-fucked me while pushing her tongue into my dilated asshole, the muscles contracting around her tongue as waves of amazing pleasure overcame me.

We swapped positions so that I was lying on the floor, Helena straddling me in the 69 position, while Conchita sat on the couch, legs apart with two fingers crammed into her pussy. As Helena continued to eat me out, I eased two fingers into her anus while burying my tongue in her cunt, which was shaven and smooth, slick with her arousal. I began pumping my fingers into her ass rhythmically, feeling her heavy tits brushing against my stomach with the motion, her fanny wide open as I tonged her engorged clit. Conchita then knelt between my legs and as Helena sucked and nibbled on my clit, she began licking, then finger fucking my asshole. I brought my knees up to make it easier for her, and came again very quickly. Eventually, as my whole mouth was beginning to go numb from the effort, Helena also came, her pussy dilating and contracting around my tongue, her asshole tightening around my fingers.

We all collapsed in a heap, exhausted from our exploits, happy grins on our faces. We've been firm friends (and lovers) ever since.
