Chronivac Version 4.0

Leah's expanding doughnut

added 2 years ago A BM

“Oh man, it's still so swollen…” Leah frowned at her reflection over her shoulder.

5 days on from Eric finally penetrating her, and her ring was still swollen. When she woke up the following morning with a hot sensation in her ass, a memory of his hot cum finally inside her, she thought nothing much of it. After all, Eric had only just fucked her with a horsecock. Really all that stuck with her that morning was the remembering what it felt like when his cock flared as he came. Rushed with blood the flat head of his horsecock had almost doubled in diameter. The feeling at the time was immense, pleasurable, but also painful, pressing against her insides so much she felt her hips expand from the inside and vaginal canal squashed flat by it; it was an incredible memory and happened so fast she was curious to try it again.
As the days went by though, the heat at tender feeling inside her subsided, but the swelling around her rim did not. She now wondered if they were linked.

Currently, her ring looked like a glossy, black, overinflated doughnut. It was incredibly soft to the touch and super pliable. Despite initial worries, and the first night where it constantly drooled horse cum, it was doing its job as normal, and Leah had no issues going to the toilet; other than the fact that wiping and cleaning herself made her want to play with it more.

Worrying swelling aside, her ass still itched and craved for contact. Every evening Leah gave in strumming herself off with the handle of a hairbrush shoved up her ass. She did think that it was probably because of this that her ass remained swollen.

She let go of her spread cheeks, they clapped together once, then separated slightly in the middle. Leah could feel they weren't touching at rest. So swollen was her ring that her cheeks were being kept apart. She frowned again, still worried.

Dressing herself for the day she pulled up a pair of cotton panties that wouldn't stop getting wedged in her ass crack, and dug into her hips.

Suited and booted for school Leah came down the stairs to her mum making breakfast.

“Morning love!” her mother greeted her, “pancakes on the table, I have to run. Rush on the E.R. this morning. Another bunch of people bitten by giant rats. Swear we need to de-vermin this town.” She sounded exhausted.

Moments later Leah was by herself again, munching the soft fluffy pancakes and shifting from side to side, feeling fabric pull tight against her swollen asshole, wishing Eric was having breakfast with her.

“One more day…” she breathed, then school was out for the summer and she'd be able to spend more time with her secret man.

One hand down the back of her skirt, fidgeting with her ill fitting panties, Leah munched hungrily at her breakfast.


“And then there were 2 more rats under the hedges outside the main gate too. They were huuuuuuge! Like dogs!” Leah was excitedly telling Eric. Hand in hand they hiked a route through the quiet woods.

“Teacher called the exterminators, but they said they were too busy somewhere else"

“So what happened then? What did they do with them all?” Eric asked.

“Nothing!” Leah giggled, “We just had to leave the school, rats squeaking and having sex everywhere. Sasha was crying because of the rat semen she got on her shoes and tights. I thought it was funny.”

“I guess she didn't…” Eric ventured as Leah nodded assent. “It got on her hands and everything, she was not impressed…”

“Bit mad isn't it! Plague of giant rats all around town, all having sex everywhere!” Leah commented, sidling up beside Eric, casually slipping her hand into his. He gripped her hand tight and pulled her in. His heart swelled as he did so.

“Madder than having a boyfriend 6 years your senior, who has a horses penis?” He countered.

“I suppose not! But… I like your penis.” Leah blushed. Eric was acutely aware that she'd never seen another, no human penis, only a horse one. This had to be affecting her sexual development.



“yeah!” Eric chuckled, “free now though, for the whole summer!”.

“yes! Free!” Leah beamed. “Mom never minds me disappearing for hours a day. So we've plenty time to hang out!”

She swung around and threw herself into his path to stop him. Then pressed herself against him. She was warm and soft looking up at him. “And plenty time for smooching!” she smiled and pursed her lips.

Eric laughed but then leaned down to give Leah a hungry kiss. She was grinning ear-to-ear when they resurfaced for air.

“What?” Eric smiled back. Leah's eyes darted down for a moment and she leaned into him; her warm body softly pressing against his hardening horsecock. “Oh, I'm just happy to know you like me.” She teased, beaming, large white teeth framed by black lips and soft brown eyes.

“Of course I do, fool.” Eric responded, good natured. “You're the only one who'd put up with my weird cock!” he joked.

She laughed, “speaking of which!” she pointed at his crotch. “Time to undress mister!”

Eric glanced around, making sure no-one was around. Not that anyone would be off-path in a secluded wood like them, but it paid to be safe. Opening his backpack he pulled out a blanket and with a flourish laid it on the loamy ground.

Within a minute Eric was standing naked, cock slid out of his sheath, dangling and bobbing free. Across from him Leah stood in only her white panties, the back wedged in between her cheeks, giving her a cameltoe in front. Already excited her nipples were puffy, making her tiny proto-breasts stick out from her shiny dark chest. Looking delicious, Eric couldn't help kneeling down and taking them into his mouth one at a time, drawing on them; sucking and rolling his tongue over the soft bumps while Leah gasped into his hair.

Eric drank deeply of Leah's scent, the warm scent of her skin and slight smell if sweat from an active day. He released her pubescent nipples and kissed around them, up and down her chest.

When he got to where her arm met her chest, Leah raised her arm and stretched giving Eric full access to her underarm. Her salty smell was strongest here and enough to make Eric's cock jump from where it was poking under her spread legs and thump Leah in the backside.

Leah grunted, “Are you knocking at my back door already?” She wheezed, exhaling happily while he nuzzled her. As if in response Eric's cock jumped again, slapping her directly between the cheeks, making Leah's doughnut wink. “Hhnngh" she moaned into his head again.

“You okay after the last time? Nothing hurt?” Eric asked between kisses. Leah thought about it, about her doughnut ass, how the swelling wasn't going down. Sex had obviously done and was doing something to her. She didn't hurt though, everything felt good and exciting so far. She definitely wanted to go again.

“All good! Wasn't sore at all!” she chirped, Eric smiled in response. “Good!” he said finally, before adding, “Sorry again about this stupid horse penis…”

Leah stood up straight, and reaching behind her, fumbled for Eric's warm silky shaft and pressed it between her cheeks. “Don't be… I like your penis. I'm glad it is a horse one.” She leaned forward and kissed him softly on the lips. As she leaned her cheeks parted more, and Eric could feel her warm soft rosebud being pressed against his cockhead, slowly stretching sideways, and enveloping the head of his cock. Leah moaned as she pushed the head in, slowly but surely. Half the head went from the rigde without much resistance; then, stretched across maybe half of his cockhead Leah had to shift and push the head dead on. She felt the swollen ring stretch taut, then stretch some more, covering more and more of Eric's cock head. Her eye screwed up in concentration until, with a pop, her ass engulfed the entire head. She immediately sank about 4 inches onto the shaft and felt the head press her insides. It made her feel incredibly full.

“Don't move!” she grunted. There wasn't enough lubrication for Eric to start pumping away and she didn't want tit to hurt. She was happy just with the feeling of him stuffing her full. “Hurts?” asked Eric, concerned. Leah shook her head, “Not like this, feels nice and full. But could hurt if you move". Eric nodded understanding, their lips met gently for a moment and then Leah leaned back, legs still spread and bowed.

With her leaned back, impaled on his cock, Eric had full access to her pussy. Carefully and gently he ran his fingers along her swollen lips, they came back slick with clear juices. He brought them to his mouth and gently tasted his girlfriend. She was warm, musty, slick.
Placing his palm on her lower abdomen, he began rubbing the prominent hood of her clit with his thumb, Leah gasped and grabbed Eric's head, pressing her small body against him.

His thumb swirled at first gentle, then as Leah began to squeak, moan and pant, he began to rub harder. Her body writhed and twitched on his cock, Squeezing it and stimulating it.

“Oh god.” She gasped into his scalp. “I feel so full! Can… can your penis do that thing where the head expands now?” she whimpered into his ear. “can you squeeze my tummy inside?”

Hearing the young girl beg to have him cum within her was enough to get the process going. Blood rushed to Eric's cock. He felt his sphincter tighten as he clamped down. He felt the already squashed head of his cock expand and expand, filling with blood; as another fluid gurgled deep within him. As the expansion neared its peak, Leah cried in shock, pleasure and pain. She could feel the cum rushing up Eric's shaft until finally with a pulse it began hosing her insides. She felt the warm liquid shoot up her ass, backfilling her bowels. There was a lovely itching to it as it spread inside her; she loved this feeling, she loved having something of Eric's as part of her now.

Hungrily she kissed him and hissed “stay there. Stay part of me.”

“Doesn't hurt?” Eric panted, spent. “Doesn't hurt.” Leah confirmed.

“Okay…” Eric wrapped his arms around her small trembling body and pulled her in close.

They rocked and held like that, Leah sinking slowly as Eric's cock slowly retracted and softened; all the while her ass held on to his cock-head like a vice.

“This can't be good for your bum Leah…” Eric croaked eventually. Leah, cheeks still burning, giggled. “Ah it was just a bit swollen last time. All okay"

“Swollen?” Eric inquired in a worried tone. “Oh… like a bit puffy… not sore at all though.” Leah admitted. “felt good to touch really”. She added.

“Good how?” Eric asked. “Ah I dunno…” Leah sighed. “Just feels good all puffy. I can always feel it.” Her fingers swirled on his chest. “Reminds me of when you're inside me.”

“Well… be careful please. I don't want to hurt you, or do damage.” Eric pleaded. Leah responded reassuringly. “Of course. It feels good. Doesn't hurt. Just is a bit puffy.”

Eric frowned but conceded as she finally pulled back and slipped from him. She felt her ring snap shut like an elastic, cum oozing from the centre. She flopped onto her back and pulled her legs to her knees, baring herself to Eric.”See! All fine" she grinned. Eric looked down at the glossy, puffy ring. Something looked weirdly familiar about it. It didn't look hurt or damaged, like she said, just puffy. Like an inflated tyre.

“Well… just look out for it. I don't want to hurt you". He concluded.

Leah grinned, blowing him a kiss. “what you do to me, definitely is the opposite of hurt!”
