"OK, don't tell me."
When the milk was simmering, Samantha poured it into the mug and then added most of the contents of the phial, leaving just a tiny trace in case, she told herself glumly, it was required for later analysis. She stirred thoroughly and bore the mug through to her sister.
"Thank you, sweetie," said Rosie, smiling at her. "What would I do without you?"
. . .
Samantha was woken at three o'clock by the rhythmic banging of Paul and Rosie's headboard against their bedroom wall. Rosie had confided that she hadn't felt like having sex since her positive pregnancy test so this, at any rate, was progress. Less a fertility drug, thought Samantha as Rosie began to cry out in orgasm, than an aphrodisiac. Either way, it was a bargain.
Her train of thought was interrupted by a scrabbling noise from under the bed. The box! She leaned over and groped until her fingers found the shifting wooden casket and pulled it out from beneath the bed. She sat, naked and cross-legged on the white sheet, and very slowly opened the box. Crammed inside were five tiny creatures.
Samantha switched on the bedside light and peered at them. Not gremlins, she thought, although they gave little squeaks of protest at the intrusion of light. They were vaguely humanoid, tiny, pale creatures who looked like they'd lived in the dark all their life. All five could have nestled comfortably in the palm of one of her hands. They had lumpy, wizened little faces, disproportionately long, knobbly limbs and webbed hands and feet with sharp, barbed nails. And attached to their shoulder blades were paper thin, veiny wings. They were looking curiously back at Samantha, chattering. She lifted the box towards her face, smiling, and as the box reached the level of her breasts, the chattering became more animated. One of the sprites pointed at her breasts and all five stood on tiptoes to get a better look. Suddenly, two of the tiny creatures spread their wings and leapt from the box, extending their sharp little claws and reaching out for her tits. Samantha gave a little shriek as the barbs of their nails sank into her areolae and dropped the box. The creatures inside squealed angrily but Samantha was more concerned with the ones on her chest. She went to brush them away, but they were securely attached and could not be dislodged. She peered down at them in distaste and together they opened their little mouths, revealing rows of tiny razor-sharp teeth, and latched on to her nipples.
Samantha gasped and fell back on her pillows as the banging of the headboard in the next room resumed. The creatures sucked hungrily on her breasts, pulling as much of her soft flesh into their tiny mouths as they could. She was about to attempt to push them off again when she realised that the sensation was pleasurable. She had always loved having her nipples sucked and however tiny their mouths, the creatures were exerting powerful suction. She put her hands behind her head and surrendered herself to pleasure, her pussy beginning to juice. The three sprites from the box were pulling themselves onto the rim, and as she moaned in arousal they jumped lightly onto her belly and crept up to take a closer look at her face. She opened her eyes, which had closed in ecstasy and looked them over. Between their legs they had tiny penises and scrotums, she saw, which now were swollen and rearing up against their bellies. She smiled at the sight and they chattered to each other before, by common consent, making their way back down her body.
She was writhing and moaning at the tingling in her nipples when she felt a pricking in her groin. One of the sprites had sunk his little claws into her and was now sucking on her clitoris. She sucked in her breath in shock and bucked beneath his ministrations. The two remaining sprites were pulling back her labia, running their tongues along their length. Samantha was losing control. She arched her back and squeezed her eyes shut. In the next room, Rosie was reaching her own crescendo. Just as she began to cry out, the two sprites crawled inside Samantha's sopping pussy and she came explosively, thrashing about on the bed.
If she'd thought the little creatures would stop now she had climaxed she was wrong. The sprites simply traded positions, the ones who'd sucked her nipples burrowing into her cunt and rolling around, humming and causing delicious vibrations inside; the one who'd sucked her clit ceding to one who'd emerged from her pussy and, with the other, crawling up to set to work on her nipples.
Samantha rolled around, overloaded with sensation, trying to prise them from her sensitive flesh, but their little barbed claws were sunk in deep and she couldn't remove them. They forced her mercilessly towards another orgasm, and another, and another - until Samantha slipped into an exhausted sleep in which she came repeatedly until morning, when the creatures, sated at last, fluttered back into their box and pulled down the lid to shut out the morning light.
. . .
Samantha buttoned up her shirt gingerly over her inflamed nipples and made her way downstairs on shaky legs. Rosie and Paul were already eating breakfast at the kitchen table. Paul looked exhausted, but Rosie was full of beans, humming as she bustled around the kitchen and smiling radiantly.
Samantha and Paul exchanged a meaningful look behind Rosie's back. "Good night?" Samantha mouthed. Her brother-in-law shrugged, rubbing his tired eyes.
Rosie was still off work sick and once Paul had kissed her goodbye and departed for the office, Rosie brewed two more mugs of tea and the sisters curled up together on the lounge sofa.
"What a night!" Rosie breathed, still grinning.
"Hmmmm," said Samantha. "I couldn't help hearing you two going at it like teenagers."
"Twice," added Rosie, smugly. "And then I had the most incredible dream. A hooded creature was fucking me in a forest. It had a huge cock - I could almost feel it in the back of my throat - and it came gallons, deep in my womb. When I woke, I was in the middle of my third orgasm of the night!"
Samantha stared at her. "Rosie!" she gasped. Her sister had never shared anything like this before.
Rosie laughed at her appalled face. "I'm sorry, Sam," she said. "But it was incredible. Come on, let's nip down the high street for a spot of window shopping."
When Samantha went upstairs for her bag, the box was rocking violently on the floor. She carefully eased it open and peered in at the five ugly little faces, flapping their bat ears at her. "Sssssshhhh," she implored them, putting her finger to her lips. As she slackened her hold on the box, the creatures, in concert, thrust the box fully open and took off. One by one, giggling, they plunged down her shirt front and took up position, their little barbs sinking into her soft flesh. She gasped and gave a little sob, bracing herself for the assault on her tender erogenous zones, but it didn't come. The creatures on her breasts and clit just snuggled peacefully against her and the ones in her pussy curled up quietly and were still.
They remained quiescent as the two women shopped. It was only when they sat down in a cafe for a break that the sprites awoke and began again to suck. Samantha wriggled in her seat and Rosie gave her a curious look. "Wedgie," Samantha said, "Excuse me while I sort it out," and she hobbled to the loo. Locked in a cubicle, she seized the creature on her clit and tugged. Quick as lightning it twisted its ugly little head, hissed loudly and sank its pointed teeth into the fleshy mound at the base of her thumb. Samantha shrieked and snatched her hand away, watching as the blood welled up and ran down her wrist. The sprite glared at her and lowered its head, resuming sucking with enthusiasm. Samantha leaned forward, hands on the cistern, and gave herself over to the sensation, shuddering as she came.
. . .
Two weeks later, Rosie announced her pregnancy. Samantha, by this time drained and pale from the round-the-clock assault on her body yet with breasts bigger than ever, reacted with little enthusiasm. Rosie, misinterpreting her lassitude, hugged her and said, "Don't worry, darling. It's going to term this time. I can feel it."
Scans came and went and the foetus thrived, a little larger than average for dates but giving no cause for concern. It was active with a strong heartbeat and its mother glowed in pregnancy. She bustled around, preparing a nursery and researching classes, while her sister faded, enduring orgasm after orgasm at the hands of the fae.
Paul, too, was suffering. Worried about the baby, Rosie had banished him from the bedroom after her 12 week scan. As the months passed he became more and more despondent and their arguments about sex resounded through the house.
One morning, as Rosie was out at a breastfeeding class, Samantha found him packing a bag, tears streaming down his face. "I can't stand it, Sam," he said. "She acts like I repulse her."
"But, Paul, you can't go! What about the baby?"
"I know. I'm a heel, but I just can't cope any more without sex."
The wise woman's words echoed in Samantha's head: "Rosie is likely to lose interest in Paul altogether. You might well have to fuck him while she is pregnant, to hold them together."
Samantha took his face in her hands and kissed him with infinite tenderness. His hands found her waist and she stiffened as his left hand burrowed beneath her top and crept up towards her breast, but the creature suckling there detached itself and crawled round her body to her back so when she cupped her breast in his hand he found only soft titflesh and a swollen sensitive nipple.
"Your tits are bigger," he muttered into her hair.
She took his hand and led him up to her bedroom. As he turned his back to undress, the creatures fluttered down and crawled beneath the bed to their box. Paul lay on the bed and Samantha's skinny frame straddled him, guiding his thick penis into her swollen pussy. She rode him slowly, rolling her hips, and he gazed at her engorged breasts, bouncing on her ribby torso. After his enforced celibacy he couldn't last long and came inside her after only a few minutes, apologising over and over for not making her cum. But Samantha had had enough orgasms in the past few months not to care if she never had another. She lay on top of him, his softening cock slipping from her pussy, and nuzzled his neck.
