Delina threw her teacher's legs over her shoulders. She had spent the last five minutes playing with her boobs, licking and sucking them until Mrs Mwera was groaning like a patient in a Flying Doctors' ambulance. Now, she stared at her language teacher's dark pussy lips shining with the juices of arousal. The sparse cunt hairs clung to the sides as if fearing they would fall into the pink depths. Delina lowered her mouth to wash the thick lips with her outstretched tongue.
"Tss-aah" wailed the poor teacher. Arms supporting the thick thighs, the girl lapped the lips up and down, spreading saliva and cunt juices all over the outer lips, which were gaping open ready for anything. "Aaaaah," wailed the teacher again, this time because Delina's partner in crime Marge, behind the sofa and leaning forward, had taken their teacher's boobs in her hands kneading them, and squeezing the nipples gently. At the same time she was running wet lips over Mrs Mwera's very sensitive neck and ear region. The young Ruthie sat in the opposite sofa watching all this going on, remembering how she had felt two days before, when her bathtime was invaded by these two girls. A wild mixture of pleasure and embarrassment came over her again. She clamped her naked thighs together, yet the smells, sights and sounds of girl-on-girl sex were getting to her. Delina's bottom as she knelt between the teacher's legs seemed to invite her, but she had been ordered to sit still.
Then Delina invaded her teacher's inner lips with her tongue, flattening them against the sides of the wide-open cunt. "Wuuuui!!" the teacher gasped in ecstasy. She ran her wicked tongue along the gash left by the inner lips, stopping just before touching the clit. Mrs Mwera had been expecting the tongue to visit her clit.
"Oooh, don't torture me that way, girls!" For answer she felt a finger at her cunt's entrance, rimming the hole. Slowly as the tongue continued its depredations, the finger pushed into her hole. It set up a fucking motion, before it was crooked to attack the roof of her channel, where folds and grooves lay hidden. As this was rubbed, by the tip of the finger, the teacher's boobs were being sucked. At one and the same moment, Marge sucked one nipple into her mouth, Delina's tongue eventually arrived at the clit and the rubbing of her G-spot hit a peak.
