It was the next week before anything else really sexy happened, Sally had been at home sick, sometimes she even felt too awful to masturbate. But she was back at school now, she felt great and really horny. It was in the morning assembly that she and Gill first got the chance to get erotic, Sally was gagging for sex, so her skirt hit the floor even before she had sat down. Gill smiled and moved her hand between Sally's open legs. At the first caress of her pussy lips Sally's desire burst, she started to undo her blouse; by the time Gill had two fingers inside her, Sally had all the buttons undone and was pulling it off her shoulders. Then Gill removed her fingers and started to whisper to her girlfriend, "now you're naked you're to do exactly as I tell you". Sally nodded vigorously, Gill continued "you've got to keep your legs wide open but your arms crossed in front of you, no touching yourself". Sally did as she was told, reluctantly but she did it. Gill then started to tell her about the previous night "Lucy and I went round to Miss Carter's house, we were naked underneath our coats so we groped each other constantly. You know when Lucy is turned on she gets really randy. She was walking along coat over her shoulder for ages, her lovely firm body moving beside me, then she stopped and without a word bent me forward and gave my arsehole and cunt a great licking -- right there in the street!" Sally was now trying to grind her cunt on the seat she was so horny. "Stop that" urged Gill and flicked Sally's left nipple, the waves of pain and pleasure merged through Sally's naked body and Gill could easily smell the musky juices from her girlfriends sopping pussy. Gill continued to tease Sally "When we got to Miss Carter's she was wearing the tiniest pair of panties you have ever seen, they were still too much though, so we pulled them off in seconds. We went inside, it was lit with candles, there was some hardcore lesbian porn on the video and her collection of dildo's and vibrators was out and ready. But now you'd better get dressed as the assembly is finishing". Sally looked round in chagrin and so reluctantly pulled on her skirt and blouse.
They were walking to their next class when they met Lucy, Sally was desperate for sex now and she ground her body against Lucy and said "take me, I'll do anything, just make me come". Lucy looked at Gill and smiled "Come on then" she said to Sally, "but you'll be mine for the rest of the day". Sally nodded eagerly, the three girls then went into the nearest toilets; Sally didn't even wait to be asked, she stripped off immediately then leant back invitingly with her legs wide open. Lucy made an appreciative noise then knelt between Sally's legs and began to expertly lap at her clit. Sally began to knead her tits until Gill moved forward, took her hands away and replaced them with her mouth, sucking and licking on the hard nipples. Lucy inserted two fingers into Sally's sopping wet pussy and Sally began to whimper as she approached orgasm. Her orgasm was predictably powerful and she shook and twitched as the two girls continued to stimulate her. Lucy then stood up and offered her juice covered fingers to Gill to suck on, who was never one to turn down such an offer and happily slurped away whilst Lucy said "right Sally, you're mine now, and seeing as you're naked let's have some fun". Lucy looked around then had an idea, she walked to the door, looked out, then beckoned to the two girls. Sally and Gill followed along, Lucy lead them to a section of the corridor that was open and light, then turned to Sally and said "I want you to put on a show for us, if it's horny enough we'll give you a good orgasm". Sally started to dance; twisting, turning, showing her lovely young body off to it's best, then it started to get more erotic, she started stroking her breasts, then down to her pussy. She ground her crotch onto her hand, then turned round and bent over, reaching round she pulled her pussy lips apart and heard the gasp from behind her as Gill and Lucy looked deep into her moist snatch. She then reached a little higher and pushed her first finger into her bum, it was joined by her middle finger, then by the first and middle fingers of her other hand. Feeling her bum muscles relax she then pulled her bumhole open, both Gill and Lucy were right there to look into her bum and then they both squeezed a finger each into Sally's bum. Sally now felt very full and very horny, so when Gill leant over and stuck her naked bum next to her face she didn't hesitate in enjoying it to the full.
Gill then pulled Sally upright, knelt between her legs and pulled Sally onto her face. Sally ground her wet crotch all over Gill's mouth and nose, she was so turned on she couldn't stop the small dribble of urine that escaped her into Gill's mouth. Gill looked up at Sally and begged "more". Sally reached down between her thighs and opened her pussy, then concentrated and jetted a stream of golden piss into Gill's mouth, then she started to move her hips around so the flow covered Gill's face. After she was empty she quickly bent down and began to lick and suck her piss from Gill's face, occasionally stopping to snog her. Lucy stood there watching them, she was frigging herself furiously. "I can't believe you two just did that" she moaned. Gill looked at her, "it's divine" she said, "would you like me to do it to you?" Lucy hesitated for a few seconds then nodded excitedly. "Kneel down then" said Gill. Sally knelt down behind her and started grinding her minge over Lucy's firm arse whilst reaching round to take over the fingering of her cunt. Gill straddled Lucy's face and pulled her pussy lips apart, then relaxed. The flow of golden piss from Gill's cunt at first caught Lucy by surprise, and then she opened her mouth to let it gush in. Sally lapped at the drops coming from her cheeks and chin, making sure none was wasted. When the stream finished Lucy grabbed Gill's hips and dragged her in so she could slurp the last drops from around Gill's cunt, then she looked up and said "I want to do that again, it tastes fantastic!"
