2 months on and Leah knew something was up, as she studied her naked reflection in the bedroom mirror. She wasn't long into her summer holidays and only two weeks past her 12th birthday, but puberty seemed to have finally hit her; and it hit hard, at least in her bottom half.
Her hips were widening, finally shifting her frame from the gangly childish legs to a more womanly frame. She was a long way off grown-up looking, but her hips were certainly not that of a pre-pubescent child anymore. She turned side on to regard her reflection from a different angle. Her but had also filled out, muscle and fat giving it a gorgeous shape, ripe and firm.
Her hands ran down her sides and trailed over her hips, before squeezing her butt cheeks, testing their firmness and bounciness. She smiled at the result. Hands now close to her asshole, she couldn't resist snaking a hand between her cheeks, not needing to part them, to run her fingers around her puffed up ring. Inexplicably, it had gotten even thicker in the last few weeks, now the diameter of a coke can, and sticking out at least a thumbs width from the rest of her skin. It was large grotesque, sensitive, and she loved it.
With her wider hips, stance and pliable hole, she now had no problem taking Eric's horsecock for anal sex, which is where she had just come from.
Summer holidays had been the perfect opportunity for the two of them to spend a lot of quality time together. With both of their mother's working constantly, and both of them out of school, they spend most days in each other's company, and most of that time was spent behind locked doors.
They'd gotten into a serious rhythm, and Leah's appetite had grown massively. Most nights she went to sleep with a tingling asshole holding in a large load of horsecum.
Just the thought of the current load sloshing around in her bowels now made her pussy tingle in sympathy. Her other hand snaked down to her wet folds and grabbed the hood of her clit between thumb middle and forefinger. She grunted and began gently putting pressure on her enlarged clit.
Along with her hips and ass, Leah's clit had begun to grow too. Always on the big side, it had begun to swell even further in the last two weeks, now the size of a man's grown thumb; though still always fully covered by her clitoral hood. Between her large clit and monster asshole, Leah had had to shake up her wardrobe. No longer could she wear leggings without making it painfully obvious that her asshole and clit stood out massively. Instead she's either covered the leggings in shorts and skirts, or avoided pants in favour of dresses altogether.
Eric's favourite place of course, barring buried deep within her, was with his face stuffed between her legs, sucking, licking and kissing her clit. Her lovers head is what she imagined as she began to tug more roughly at her clit; back curving and hips sticking forward in pleasure. Her eyes rolled and she began shaking. Mumbling to herself.
So enraptured was she by the time her orgasm hit that she didn't even hear the door to her room open.
"LEAH CHILD! What are you?..." She froze grunting in shock.
"OH MY GOD BABY. WHAT IS HAPPENING TO YOU?" Leah's mother called out.
