One lunchtime Sally was by herself in the library, which was very unusual. She could call on many girls for sex, so she was never normally alone but she simply had to finish this homework. She thought wistfully that Gill and Lucy were probably finger deep in some lovely girls' body by now, or having their lovely cunts tongued to perfection. Snapping herself out of her fantasy she went back to concentrating on the work, maths was so boring unless you were counting the number of orgasms or dividing girls legs. She had secreted herself away in a corner to concentrate and was in her usual homework mode -- legs open, skirt round her hips and fingers gently caressing her cunt; sure the sensation was slightly distracting, but less so than her pussy screaming for some attention! She thought that she was away from curious eyes, not that she really minded, deep inside she always had the urge to strip naked and offer herself to all and sundry -- maybe even the boys might get a look in, she loved getting fucked after all. Yet again reason took over, getting naked and offering herself to all -- maybe, letting boys do anything -- no way, she simply couldn't visualise a situation where a man entered into her sex life. "Dammit do your math", she implored herself and got back down to the simultaneous equations that had ruined her lunch hour.
To her credit she concentrated so hard for the next ten minutes that she didn't see that someone could see her, looking up though it was obvious. Standing about ten feet away was a rather yummy looking blonde, Sally hadn't had much contact with her as she was in the other half of the year, but she knew her name was Carla -- she also knew she was interested. Although she had turned a rather fetching shade of red at being caught, Carla was still staring at Sally's slender fingers stroking her cunt. Sally waved her over; she approached nervously and sat down. "Would you like to help me with this?" Sally whispered; "the math or that" responded the newcomer, looking down between Sally's legs. "Both would be nice" Sally laughed back. "It would be too obvious if I were just to lean forward and starting rubbing you", whispered Carla nervously "we might get spotted". Sally of course wasn't bothered but she had to make allowances for the other girl, "Ok, why don't you use your foot" she replied. It was an unusual suggestion, Carla's surprised look confirmed this, but Sally had a way of taking girls into extraordinary situations they ended up loving every second of it. Carla slipped of her shoe and lifted it towards Sally's crotch; "take off your panties first, so I can see your pussy as you do me" suggested Sally. Carla stopped, then raised her bum off the chair and pulled up her skirt, "let me" murmured Sally, leant forward then hooked her hands under both sides of the pants and slowly pulled, running her hands all the way down the firm legs of the other girl. She looked appreciatively at the tightly cropped bush of pubic hair and the already wet and hot looking pussy below it.
When she had let Carla's pants fall to the floor she stood up and quickly pulled off her skirt, then sat back down and opened her legs. Carla's right foot crept back up then tentatively began to rub Sally's moist hole. Sally ground her hips back enjoying every second of this encounter, "push your toes into me" she mouthed. Carla now began to push her foot forward into Sally's cunt, which began to relax and allow more in. Sally couldn't take much more and grabbed hold of Carla's heel to increase the pressure, she wanted the whole foot inside her, and she'd been fisted before so why not foot fucked. One big push from both girls and the foot slid in, right up to the bridge. Carla couldn't believe it; neither could Sally who was in heaven, especially when Carla wiggled her toes. "Do you want to see my tits?" panted Sally, Carla nodded so Sally quickly unbuttoned her blouse and pulled it open. Carla was entranced by watching the firm breasts topped by the hard nipples moving up and down as Sally's chest heaved with passion. "Can you open your legs wide enough to get the soles of your feet together?" Sally now asked. "Yes, why?" queried Carla, "then do it and try to get your other foot inside me too", responded the nearly naked blonde. Now Carla really couldn't believe it, but the look on Sally's face told her to try, she rotated her right leg then brought the left foot up to join the right. The foot twisting inside Sally made her cum, and as she felt the toes of Carla's left foot squeeze inside her she cam some more. As Carla pushed Sally felt her cunt stretch, she loved it, the pure thrill of doing something so rude and unusual in such a public place really got her going, so when she could expand no more her whole body was racked with the most fantastic vaginal orgasms ever. Carla felt the spasms around her feet, then came herself -- without any stimulation -- when Sally's cunt wrapped her feet in juices.
It took some time for Sally to come back down but when she did she moved her cunt off the two feet inside her, then went to work licking and sucking her cream off. Carla was now squirming in pleasure, which multiplied when Sally almost dived forward between Carla's legs and began tonguing and fingering her cunt. Earlier she had been reticent about having sex in such a public place, now she couldn't care. Sally was a master of oral sex and she knew it. Sally adored showing off her body and pushing sex to the extreme, she would try virtually anything, be used in any way by the girls she loved because she knew she could make it up to them once she got between their legs. Carla had now found that out and she was now totally committed to lesbian sex.
