The three passionate, naked girls then heard a noise behind them. Miss Carter was standing there watching them, smiling she said "you three are taking a bit of a risk, but I feel horny so let's have some fun". Sally was still knelt behind Lucy enthusiastically humping her pussy onto Lucy's firm arse cheeks, so Miss Carter called her over. Sally regretfully stopped, leaving Lucy's bum shiny from her juices, it didn't stay that way for long as Gill pulled her to her feet and began licking the juice off. Miss Carter dropped her skirt to reveal her newly shaven pussy, then pulled a strap-on dildo out of her bag. As she pulled it on she told Sally to lean up against the wall and open her legs, then she moved between the schoolgirls open thighs. As the knob of the dildo nudged against her pussy Sally moaned then gasped as the length entered her, she raised her leg and wrapped it around her teacher to get all of the dildo inside her, then relaxed into being shagged. As Miss Carter's hips ground the false cock into her pupil the two passionately kissed and groped each other. After a few minutes of great fucking Miss Carter said, "I want to fuck your arse now". "Please don't stop, I'm nearly there" replied Sally, "If you get naked in my next class and do anything I desire I'll take you there" bargained the teacher; "Yes, anything, I'll do anything" moaned Sally. Miss Carter then speeded up her hips, Sally bucked and ground herself onto the dildo, work herself up to the orgasm she craved, until it finally crashed through her, she hung onto her teacher for support as her body twitched uncontrollably with pleasure.
In Miss Carter's next class, Sally and Gill had taken their customary seats at the back of the class, Sally didn't waste any time getting naked and sat there gently caressing her breasts as Gill stroked her pussy. Miss Carter arrived, she looked normal but both girls noticed she had removed her blouse so only her jacket covered her firm tits. At the first opportunity Miss Carter was beside the naked schoolgirl, she bent over giving both girls a good look at her tits, then pulled a large butt plug out of her pocket "this stays inside you until I remove it, Ok?" she whispered to Sally. Sally nodded, turned to face her teacher then lent back to allow access to her bum. Miss Carter quickly fingered Sally's cunt then greased the plug with the juices and carefully inserted it into Sally's tight bum. It wasn't easy as it was rather large, but once it was all the way in Sally very full and very horny. Miss Carter then leant over to Gill and whispered "keep playing with her, I want her nice and wet", Gill nodded and reached between Sally's legs and slipped two fingers into her cunt. Sally by now was in heaven, her bum was full, her cunt getting fingered; she sat there moving her hips and stroking her firm tits and rock hard nipples. When Miss Carter returned Sally was soaking wet, the teacher gestured to the girl to swivel round on her seat, which Sally did. Miss Carter then produced her largest strap-on dildo, gave it to Sally then hitched up her skirt. Sally quickly positioned it and buckled it in place over her teachers crotch, then lay back. Miss Carter knelt down and moved the plastic knob up to Sally's wet hole then pushed forward. Sally stifled a gasp as the thick phallus slid in, then began to whimper quietly as her teacher began fucking her. Sally reached up and undid the buttons on Miss Carter's jacket and then slid it from her shoulders. Despite the risk the horny teacher was dominated by the grinding of the back of the false cock on her clit, so she pulled the jacket off and leant over her pupil so that her tits caressed the breasts of the younger women. She fucked harder and harder, both now oblivious to anything but the feeling between their legs. Neither had long to wait for their orgasms and both shook as the pleasure ran through them then Sally dragged her teacher down onto her and kissed the women hard. As they broke up Miss Carter whispered "you can pull that plug out of your bum now and push it into Gill, because next I'm going to fuck your arse".
Sally quickly leant sideways and pulled the plastic plug out of her tight arse then looked at Gill suggestively, Gill smiled and leant over, allowing Sally access to her bum. Sally slipped two fingers into her cunt to moisten them, then gently inserted them into her girlfriends backside. Gill breathed in sharply as they slid in, then started to move her hips as Sally started to twist her fingers around. Sally fingered her bum for a minute or two whilst sucking on the smelly butt plug to lubricate it, then removed her fingers and moved the butt plug into position. Gill felt it nudge against her hole and tried to relax to ease its entry, but its size took her by surprise and she had trouble getting it all the way in until Sally reached under her thigh, frigged her cunt then smeared the juices onto the plug. As it slid all the way in Gill sighed passionately then pulled Sally in for a fierce snog, they were still kissing when Miss Carter returned to fuck Sally's bum. Sally quickly swivelled round and began snogging Gill again as Miss Carter strapped the dildo onto her crotch, then easily pushed it first into Sally's cunt to lubricate it, then into the depths of her bum. Sally again reached over to her teacher and undid her jacket; Miss Carter quickly pulled it off allowing her lovely firm tits to bounce as she fucked the teenager in the arse. Gill was being driven crazy by the feelings from her bum as the muscles stretched and tensed around the plug, she reached over and plunged two fingers deep into Sally's cunt and began to furiously frig her. Sally's tongue began to dance around in her mouth, it always did when Sally was kissing her and she was nearing orgasm. She then felt her girlfriend tense and begin to jerk as her muscles spasmed in orgasm, she pulled Sally tighter to her as she twitched and jumped uncontrollably.
